Open-source alternative to Zoom cloud recording and transcripts

Which open-source option replaces Zoom cloud recording and transcripts?

Jibri is the recording component for self-hosted Jitsi Meet, and BigBlueButton has its own built-in recordings. Neither ships a Zoom-style transcript service, so transcripts need a separate backend such as Whisper or Vosk, which you would run and maintain yourself. If you are leaving Zoom because of a renewal, a residency rule or lock-in, the first job is to export the stored MP4, M4A, VTT and CC.VTT files from Zoom before any recording capacity is designed, because those files are yours to keep and move. Confirm the export scope and retention in your Zoom account, then decide which archived recordings need to move at all.

Recording is a capacity and storage problem as much as a feature problem. Jibri records one meeting per instance, so concurrent recordings are limited by how many Jibri instances you deploy, each with its own compute for encoding. Each Jibri host also needs a Jitsi deployment with working HTTPS and a valid domain certificate, since the Jitsi handbook says self-signed certificates cause problems. For BigBlueButton, the 4.0 install documentation specifies 500 GB of disk for recordings (50 GB without recording), so ask how many hours of video you expect per month and how long each file must be kept. Plan retention, backup and access controls for the recordings and transcripts together, because a transcript is personal data when it names participants.

DeployOpen plans, implements and operates these components inside your own cloud accounts, data centers or air-gapped networks, including storage sizing, Jibri hosts, transcription backends, backup and access controls. DeployOpen prepares systems and evidence for compliance assessments, but does not issue audit reports, attestations or certifications, which remain the job of independent auditors. Before you commit, ask your implementation partner to show how recordings are encrypted at rest, who can download them, how deletion requests are honored and how transcription output is tested against your languages and accents.

How Zoom recording features map to open-source options

This table maps each Zoom cloud recording output to the closest open-source option: Jibri for Jitsi, BigBlueButton's built-in recordings, and a transcription backend such as Whisper or Vosk. Read the coverage notes first, since several outputs are not confirmed in the supplied facts and need checking with each project before you plan around them.

Zoom feature	Jitsi Meet with Jibri	BigBlueButton built-in recording	Transcription backend (Whisper or Vosk)
MP4 video	Jibri records the meeting to video files on the Jibri host. Confirm the output container and whether it matches MP4 for your Jibri version.	Recordings are published as playback sessions in the BigBlueButton recordings view. Confirm whether an MP4 export is available for each recording.	Not applicable. Transcription needs audio extracted from the video file, so plan an extraction step.
M4A audio	Audio-only output is not confirmed in the supplied facts. Confirm with the Jibri project before assuming a separate audio file.	Confirm with the BigBlueButton project whether audio-only recordings can be exported separately.	Accepts audio files as input, so an extracted M4A or WAV file can be transcribed.
Chat text	Chat is not part of the Jibri recording output as far as the supplied facts show. Confirm how chat is captured and exported.	Chat is included in the playback. Confirm whether a plain text export of chat is available.	Not applicable. Chat must be exported by the meeting platform or the chat tool you use.
VTT transcript	Not confirmed in the supplied facts. Confirm whether Jibri or Jitsi produces any transcript file.	Confirm whether BigBlueButton produces VTT captions or a transcript file from speech recognition or caption input.	Whisper and Vosk output formats must be checked. Confirm whether your pipeline writes VTT directly or needs a conversion step.
CC.VTT captions	Not confirmed in the supplied facts. Captions would need a separate speech-to-text service fed by the recording.	Confirm with the BigBlueButton project how captions are attached to recordings and whether they export as separate files.	Can generate caption text from recorded audio. Accuracy and timing depend on the model and audio quality you choose.
Cloud storage and download access	Recordings sit on the Jibri host or the storage you mount. Plan disk for recordings and a download path for users.	BigBlueButton 4.0 recommends 500 GB of disk for recordings (50 GB without recording), per the install documentation.	Stores transcripts and audio on the same server or a separate store you control. Plan retention and access control.
Automatic transcript generation	Not confirmed in the supplied facts. Jitsi does not appear to generate transcripts out of the box. Confirm with the Jitsi project and your integration partner.	Confirm whether BigBlueButton generates transcripts or captions automatically in your version and language.	Transcription is generated only after you run the model on the audio. It runs as a separate job, not as part of the meeting.
Export access for admins	Confirm how administrators list, retrieve and delete recordings, since no export API is described in the supplied facts.	Confirm the recording management options available to administrators in your release.	Depends on your own scripts or storage tooling. Define who can retrieve transcripts and for how long.

Which recording option fits Jitsi, BigBlueButton or a separate transcription service?

Recording and transcription are separate decisions. Jitsi and BigBlueButton each record meetings in their own way, while transcription usually runs as a service on separate hardware. The cards below set out when each option fits, what it leaves out and the trade-off to weigh before you commit.

Jibri recording in Jitsi

Jibri is the optional Jitsi component that records and streams meetings. Each Jibri instance handles one recording at a time, so the number of simultaneous recordings is set by how many Jibri instances you run. Each instance needs its own host capacity and enough disk for output files. Confirm how your Jibri hosts are provisioned and how recording start and stop is controlled, since Jibri does not produce transcripts on its own.

BigBlueButton built-in recordings

BigBlueButton stores session recordings on the server itself, so recording is part of the platform rather than a separate add-on. For 4.0, plan for a 500 GB recording disk, or 50 GB if you disable recording. Recordings are not transcripts, and retention, archiving and access control are your responsibility. Check how recordings are moved off the server and whether your LMS can pull them.

Whisper for transcription

Whisper is an open-source speech recognition model that can turn recording audio into transcripts. It runs as a separate job, not inside Jitsi or BigBlueButton, so it needs its own compute, usually GPU-capable hardware for practical turnaround. Test accuracy on your own accents, languages and audio quality before relying on it, and confirm the license of the model and tooling you adopt.

Vosk for transcription

Vosk is an offline speech recognition toolkit that can run on modest CPU hardware, which suits smaller deployments or sites with no GPU. Its accuracy varies by language model and audio quality, so measure it against sample meetings. Like Whisper, it runs as a separate service, and you need to build the workflow that sends recordings to it and stores the results.

Zoom Node hybrid recording modules

Zoom Node hosts modules such as Recording Hybrid and Recording Connector on your premises, but it is managed from the Zoom cloud. It is included here only as a comparison point: recordings made through it still depend on Zoom's management plane. If you want recordings to stay fully under your control, weigh that dependency against the self-hosted options above.

How recording differs between Jitsi and BigBlueButton

In a self-hosted Jitsi deployment, recording and live streaming are not part of the core meeting stack. They are handled by Jibri, which is optional and runs as its own container (jibri) alongside web, prosody, jicofo, jvb and jigasi in the official Docker setup. Jibri joins a meeting as a participant, captures the session and writes the output to storage, so recording is a separate workload from the videobridge that carries the calls.

Dedicated capture host: Jibri is designed around one recording per Jibri instance, so concurrent recordings require additional Jibri instances, each with its own capture resources.
Separate sizing: Plan for Jibri capacity on top of the videobridge sizing in the scalable setup guide, rather than assuming the bridge handles capture too.
Local storage path: Recording files land on the Jibri host or its mounted volume, so the disk you allocate there, and any copy process afterward, determines how long recordings stay available.
Optional by design: If no Jibri container is deployed, meetings run without recording, which keeps the minimum footprint small.
Rootless containers: Since stable-11146 the containers run rootless with read-only filesystems, so confirm with the Jitsi Docker guide that your Jibri volume permissions match that model.

Confirm with the Jibri project how many concurrent recordings your chosen Jibri build supports and benchmark it on your own hardware before setting a capacity target.

How recordings can coexist with Zoom during the transition

Most teams cannot move years of Zoom recordings on the first day, so old and new recordings will sit side by side for a period. The cards below cover where each library lives, how sign-in stays consistent, how links to recordings reach users, and who decides how long each copy is kept.

Read-only archive of Zoom recordings

Export the existing Zoom cloud recordings once, store the MP4, M4A, VTT and CC.VTT files on your own storage, and mark that location read-only for everyday users. Zoom keeps its own copies under its account settings, so the archive is a copy you control, not a replacement for Zoom's record. Check that file names carry meeting ID and date so a recording can be matched to its original meeting later.

New recordings on the open-source stack

Meetings held on Jitsi Meet with Jibri or on BigBlueButton write their recordings to the new server, so the two libraries grow separately. Confirm the storage path, retention job and backup target for the new server before the first live meeting. A single Jibri instance records one meeting at a time, so plan capacity for concurrent sessions in each team's calendar.

Unchanged sign-in across both libraries

Keep the same identity provider for both libraries so users do not need a second password. On BigBlueButton, Greenlight v3 can use OpenID Connect through environment variables, and the project suggests Keycloak to bridge Google, Microsoft and SAML logins. On Jitsi, the Docker setup supports JWT tokens and LDAP. Confirm that the archive viewer and the new server map the same group names to the same access rights.

Duplicate sharing links

Users who paste a Zoom link into chat will keep sending it after the move, while new links point to the open-source server. Two live links to the same meeting series invite confusion and sometimes expose a recording to people who should no longer see it. Publish one index page that lists both libraries, retire old share links in a fixed window, and check that access to the archive matches the access rules of the original meetings.

Linking recordings to chat and LMS

Where users find recordings matters as much as where files sit. For team chat, post the recording link into the channel that hosted the meeting, and for courses, add it to the LMS module that uses the session. BigBlueButton is embedded in Canvas, Moodle, Sakai, D2L and Schoology, so course recordings can stay inside the LMS. Confirm each integration with its owner before you retire the Zoom links that teachers already use.

Who decides retention

Retention is a business and legal decision, not a technical default. The records owner, typically the department running the meeting series, sets how long each recording lives, with legal and privacy staff approving exceptions for regulated content. IT applies the rule, for example through a scheduled deletion job, and keeps a log of deletions. Agree these roles in writing before migration so that archived Zoom copies and new recordings follow the same schedule.

How to move existing Zoom recordings and transcripts

This sequence moves cloud recordings and transcripts out of Zoom into a storage archive you control, and sets up recording on the self-hosted platform so new meetings are captured there before you cut over.

Inventory Zoom recordings and transcripts
The client's Zoom administrator lists every cloud recording in scope, with its owner, meeting date, size and whether it has a transcript or captions. Filter by account owner and date range so nothing is missed, and record the count per user in a shared tracking sheet. This step is done when the sheet covers every account that will be retired and each recording has an owner who is still with the organization. DeployOpen can design the tracking template and the naming convention, which is handled as part of the migration plan.
Download recording and transcript files
The client downloads files from the recordings page in Zoom. Expect MP4 video, M4A audio, TXT chat, VTT transcript and CC.VTT caption files for each meeting, as described in Zoom's file format guidance. Download with an administrator or the recording owner account, and keep each meeting's files together in a folder named by meeting ID and date. The step is complete when every file in the inventory has a local or staging copy and the chat and caption files sit beside their video. Bulk download tooling is a client decision, so confirm what Zoom's admin console offers for your plan before you start.
Verify file integrity and completeness
Compare each downloaded file against the inventory: correct file type, playable duration, non-zero size, and a matching transcript where Zoom generated one. Play a sample of MP4 and M4A files in the player the organization uses, and open a VTT file in a text editor to confirm timestamps and speaker text are intact. Record checksums (SHA-256 is a common choice) for each file so later copies can be checked against the originals. The step is done when a failure list is empty or every failed file has been re-downloaded and re-checked.
Set retention and access rules
The client's records, legal and security owners decide how long each class of recording is kept, who may view it, and how access is granted and revoked. Recordings may contain personal data, customer details or regulated content, so the rules should match existing data classification and retention schedules. Write the decisions down as a short policy that names the storage location, the access group and the deletion trigger. The step is complete when the policy is approved and the people who will administer the archive have read it. DeployOpen can prepare the policy document and the access model, and the client signs off on the business decisions.
Load the archive into chosen storage
Copy the verified files into the storage the organization selected, such as a file server, an object store with S3-compatible access, or the BigBlueButton server's recording area if that is where archived content will live. Keep the folder structure from the inventory and carry the checksums across. Run the same checksum comparison on the destination and confirm access groups match the policy from the previous step. Storage sizing depends on the number and length of recordings, so estimate from the inventory totals rather than a fixed figure. The step is done when destination checksums match the source and a test user can open a file they are authorized to see but not one they are not.
Set up recording with HTTPS and ports
On the self-hosted platform, DeployOpen can plan and implement the recording path: Jibri for Jitsi Meet, or the built-in recording for BigBlueButton. Jitsi's guidance states that HTTPS with a proper certificate is necessary for multimedia to work, so the certificate and hostname come first. Open the ports the chosen platform requires, and confirm that each Jibri instance records one session at a time, so plan how many instances you need for concurrent meetings. BigBlueButton 4.0 has its own hardware and disk guidance for recordings, which you should check against your capacity plan. The step is complete when a test meeting with recording switched on produces a file in the expected location.
Test playback and transcription before cutover
Run a set of test meetings with recording and any chosen transcription backend, such as Whisper or Vosk, and check the output. Play the recording from a range of devices and browsers the organization supports, and compare the generated transcript against the speech in the recording for accuracy on your typical vocabulary and accents. Confirm that the archived Zoom files open from the new storage with the same access rules. The step is done when playback, access control and transcript quality meet the sign-off criteria agreed in the plan, and any remaining gaps are logged with an owner. Confirm with your transcription vendor or project which language and model options fit your use case, since transcription capability is not part of Zoom's export.
Cut over and retire Zoom copies
After the archive and the new recording path both pass testing, announce the cutover date to users, switch new meetings to the self-hosted platform, and keep Zoom read-only for the agreed period so late requests can still be served. Once the retention window in the policy closes and the archive is confirmed, delete the Zoom cloud copies in line with the client's deletion procedure, and record the deletion in the migration log. The step is complete when the migration log shows every recording accounted for as migrated, retained or deleted, with approval from the data owner. DeployOpen can support the cutover runbook and log, and the client makes the decisions on read-only periods and deletion.

How much storage and capacity recordings need

Recording storage grows with meeting hours, video quality and how long you keep the files, so plan from your own meeting volume rather than a generic figure. For BigBlueButton 4.0, the install documentation specifies 500 GB of disk for recordings, against 50 GB for a server that does not record. Treat 500 GB as the baseline for the install, not as a sizing answer. Pull a few months of Zoom usage reports to count recorded hours per month, then multiply by the average file size you see in the recordings you export. Confirm with the vendor and your own environment whether BigBlueButton's recording format and retention settings match the file sizes you measured.

Several choices push storage up or down. Retention period is the largest driver, because recordings accumulate until someone deletes them, so set a written retention rule before go-live. Video recordings cost far more space than audio-only recordings, so decide which meeting types need full video. Transcript and caption files are small by comparison, but each additional format you generate adds to the total. Backup copies double or triple the footprint, and they belong in the capacity plan alongside the backup target for the recording store, not as an afterthought. Ask your storage team how snapshots and replicas will be counted.

Jibri records one meeting per instance, so concurrent recordings need planning in addition to disk. A Jitsi deployment that must record several meetings at the same time needs several Jibri instances, each with its own capacity for recording and encoding. Confirm the current Jibri limits and hardware guidance in the jitsi/jibri GitHub repository before you size the fleet. For BigBlueButton, the 8-core and 16 GB specification applies to the server as a whole, so count how many simultaneous recorded sessions one server will carry and test that load before you commit to a count.

What does it cost and take to replace Zoom recordings and transcripts?

What are the one-time and recurring costs of self-hosted recording and transcripts?

The main one-time costs are the recording and transcription servers, the initial configuration, and the work to move existing Zoom files out of the cloud. The recurring costs are hosting, bandwidth, disk for recordings that keep growing, backups of those files, and staff time for patching and monitoring. Zoom's recording itself carries no separate server cost, so every component you run becomes a line item. Ask any quote to split these out so you can see which costs recur and which do not.

How much storage should we plan for recordings?

BigBlueButton 4.0's install documentation calls for 500 GB of disk for recordings, or 50 GB if you do not record, so recording is the largest storage decision in that platform. Jitsi's recording through Jibri writes files to the host, so the volume depends on meeting length, number of recorded sessions and the retention period you set. Storage needs grow with every recorded hour, so set a retention policy before go-live. Confirm with your vendor or implementer how recordings are archived, replicated and deleted.

What drives the cost of self-hosted meeting recording up or down?

The main drivers are how many meetings are recorded, how long they run, how many simultaneous sessions you need, and how long files are kept. Concurrency matters most for Jibri, because the Jitsi setup runs one recording per Jibri instance, so more simultaneous recordings means more instances and more hardware. Bandwidth also rises with the number of participants. Transcription adds its own cost if you run engines such as Whisper or Vosk on hardware you control, and that cost grows with audio hours processed.

Can our own team replace Zoom recordings and transcripts without outside help?

A team with Linux, container and TLS experience can deploy Jitsi or BigBlueButton, but recording and transcription add steps that need testing: Jibri configuration, storage layout, transcription pipelines and access controls for the files. Jitsi's documentation stresses that HTTPS with a proper certificate is necessary for audio and video to work, so certificate management is a skill your team must own. Be honest about who will patch these systems and rotate secrets over time. If that capacity is missing, an implementation partner can work to a written scope.

Are open-source transcripts accurate enough to replace Zoom's transcripts?

Accuracy depends on the engine, the audio quality, the languages, speaker overlap and the hardware you run it on, so no open-source tool can be assumed to match Zoom's output in general. Zoom's own transcript files are VTT and caption files you can export, so compare your candidate engine against a sample of real recordings from your meetings before you decide. Measure word errors on the terms your business uses, such as product names and customer names. Ask any implementer to show test results on your own audio before accepting the design.

How long does this work take and what does it depend on?

The duration depends on the number of platforms, the size of your existing Zoom archive, how many recording and transcription paths you need, and how your identity, storage and network are set up. The BigBlueButton 4.0 documentation recommends a clean server installation rather than an upgrade, which affects the plan. Plan separate time for certificates, firewall rules such as the UDP port range, and testing. No timeline can be given without a written scope, so ask for one that lists each dependency.

How do we request a quote from a fixed written scope?

DeployOpen works to fixed scopes agreed in writing before work starts, and a quote follows from that scope rather than from a price list. To request one, list the platforms you are considering, expected concurrent recordings, retention periods, languages for transcription, the size of your existing Zoom archive, your hosting location and any compliance obligations. Ask for scope, deliverables and timelines in writing, and ask which items are one-time and which are recurring. Ongoing support and continuous testing are available as separate retainers.

How access to recordings is controlled on your own servers

Start with transport and identity, because recording access depends on both. Jitsi's self-hosting guide states that HTTPS is necessary for multimedia to work, and the handbook warns that self-signed certificates cause problems, especially with mobile clients, so plan a certificate from a proper domain before any recording test. BigBlueButton also requires a valid hostname for SSL. For Jitsi, the handbook recommends JWT token authentication over the older secure domain method, which it marks as deprecated for new installations, and suggests a separate anonymous domain for guests. The Docker guide lists internal XMPP accounts, JWT, LDAP, Matrix user verification and a hybrid Matrix plus JWT mode, set in the .env file. Confirm which option your directory supports before you choose one, since LDAP and Matrix bring their own account lifecycle and audit questions.

BigBlueButton's own access path runs through Greenlight v3, which supports external authentication through OpenID Connect configured with environment variables. The Greenlight documentation suggests Keycloak if you need Google, Microsoft, SAML or other login methods. Each BigBlueButton API call must carry a checksum computed with a secret shared with the server, and the API documentation warns never to embed that shared secret in a web page. Any integration that builds meeting or recording links in front-end code therefore needs a server-side step that signs requests. Check that your LMS or portal integration does this, and rotate the shared secret if it has ever appeared in client-side code or logs.

Access control to stored recordings is a design and test task that your organization owns. Decide who may list, play and download recordings, how links expire, where recording files are stored and who holds administrative access to the host. None of these controls is supplied by the recording software by default, so write them down and test them against your own identity provider. DeployOpen can plan, configure and document these controls and collect the evidence an assessor will ask for, but it does not issue audit reports, attestations or certifications. Independent auditors and certification bodies perform that assessment, and they will look for the access tests you ran, not for a statement from the implementer.

How DeployOpen works on this

DeployOpen plans, implements, integrates, hardens, backs up, documents and supports self-hosted open-source platforms inside your own infrastructure. For recording replacement, that means agreeing in writing which meetings must be recorded, where the files live and how transcripts are produced before any server is built.

How we scope

Inventory which Zoom cloud recordings, transcripts and captions must be kept, and who needs access to each.
Decide whether Jitsi with Jibri or BigBlueButton covers your recording needs, and record the reasons in the written scope.
Agree the storage plan, including retention periods, encryption and the expected volume of recordings in your own environment.

How we build

Deploy the recording host or BigBlueButton server in your cloud account, data center or air-gapped network, with HTTPS certificates for your domain.
Connect the chosen transcription backend, such as Whisper or Vosk, and test output quality on sample meetings from your own teams.
Test recording start, stop and playback end to end, and check that files land in the agreed storage with the expected access controls.

How we hand over

Deliver configuration, runbooks and an architecture record that describe recording, transcript and storage components.
Document the Jibri capacity limit of one recording per instance and the scaling steps your team would follow to add more.
Walk your operations staff through backup, restore and storage monitoring so recordings are handled the same way after handover.

How we support

Engagements are fixed-scope, with scope, deliverables and timelines agreed in writing before work starts.
Ongoing support, upgrades and continuous testing are available as a retainer, which you can request in the written scope.
Ask for a quote based on your written scope, since DeployOpen does not publish a price list.
