Jitsi vs BigBlueButton: when each one fits
Jitsi fits general video meetings, and BigBlueButton fits virtual classrooms. Both are open source, so the decision turns on three things: the use case, the number of sessions you expect to run at the same time, and the hosting budget you can commit to for the next several years. Jitsi Meet is Apache-2.0 licensed and is built from separate components: the Jitsi Videobridge media router, the Jicofo conference focus and the Prosody XMPP server for signalling. BigBlueButton is LGPL-3.0 licensed and is built around teaching workflows, with a heavier install footprint on dedicated servers.
Start with the use case. If the core need is ad hoc meetings, calls with external guests or a join link that anyone invited can open, Jitsi's bridge model is usually the closer fit, because you add capacity by adding bridges behind the same signalling layer. Optional components such as Jibri for recording or streaming and Jigasi for SIP dial-in let you enable only what you need. Review the Jitsi handbook architecture guide before you draw the network diagram, so your firewall and load balancer plans match the components you choose. If the core need is scheduled classes with presenters and the teaching features that define BigBlueButton, confirm each feature you depend on against its current documentation rather than assuming parity.
Hosting budget is where the two stacks diverge most. The BigBlueButton 4.0 install documentation lists Ubuntu 24.04, 16 GB of memory, 8 CPU cores and 500 GB of disk for recordings, with UDP ports 16384 to 32768 open and TCP ports 80 and 443 free of any other web server. Budget that as a recurring server cost, and plan for it to sit partly idle outside teaching hours. Neither project's supplied material gives a concurrent-user ceiling for your hardware, so ask your team to define peak sessions and run a load test on staging before you commit to either platform.
Jitsi vs BigBlueButton by use case, concurrency and hosting budget
This table maps common meeting and classroom scenarios to the platform that fits better, with the reason tied to each platform's architecture and sizing. Read it with your expected concurrency and bridge count in mind, because the answer shifts as either grows. The main takeaway is that Jitsi suits general meetings that scale out with bridges, while BigBlueButton suits teaching workflows that justify a heavier dedicated server.
| Scenario | Better fit | Why it fits |
|---|---|---|
| Internal team meetings with ad hoc calls | Jitsi | Jitsi Meet is a general meeting client built on the Jitsi Videobridge media router, Jicofo and Prosody, with no classroom model to configure for a standup. |
| Customer or partner calls hosted in your own infrastructure | Jitsi | Jitsi Meet is Apache-2.0 licensed, and its component split lets you place the signalling and media tiers where your network policy allows. |
| Large public webinars with many listeners | Depends on concurrency | Jitsi scales out by adding videobridges, so capacity grows with bridge count. Confirm your listener model and bridge design with DeployOpen or your architect before choosing. |
| University or training classes with breakouts and recordings | BigBlueButton | BigBlueButton is built as a virtual classroom and is LGPL-3.0 licensed. Confirm breakout, polling and recording behavior against the current BigBlueButton documentation for your target version. |
| Recorded sessions or streams as a standard need | Either, with a check | Jitsi uses optional Jibri for recording or streaming. BigBlueButton records natively but needs 500 GB of disk for recordings in its 4.0 install baseline. |
| Single small server with a tight hosting budget | Jitsi | BigBlueButton 4.0 needs Ubuntu 24.04, 16 GB of memory, 8 CPU cores and 500 GB of disk. Jitsi can start on a smaller host, though you should size it against your own participant counts. |
| Many concurrent classrooms on a single dedicated host | BigBlueButton | Its 16 GB and 8 core baseline reflects a dedicated server per deployment. Plan one server per class load and confirm capacity with a load test. |
| Teams that can run several media servers and monitor them | Jitsi | Adding bridges is how Jitsi grows, so this fits teams that can operate multiple nodes, load balancing and monitoring as a standing function. |
| Mixed use: meetings and classes on one platform | Depends on operations | Two platforms mean two operating models to patch and back up. Ask DeployOpen to scope one platform for both needs or a split design with separate upgrade paths. |
How Jitsi and BigBlueButton are built and what that means for operations
Jitsi and BigBlueButton both run self-hosted video, but they divide the work differently. Jitsi splits signalling, conference focus and media routing into separate services, while BigBlueButton ships a heavier, all-in-one teaching stack with published host requirements. The cards below cover what each design means for ports, patching, recording storage and capacity planning.
Jitsi's component split
A Jitsi Meet deployment combines the Jitsi Videobridge media router, the Jicofo conference focus, and the Prosody XMPP server for signalling. Jibri (recording or streaming) and Jigasi (SIP dial-in) are optional add-ons, so you install only what your meetings need. Each component can be patched and monitored on its own. Ask your team which services they will own, since the handbook architecture page describes how these pieces connect.
Concurrency grows by adding bridges
In a Jitsi deployment, the media load sits on the videobridge, so more concurrent meetings are handled by adding bridges behind the same signalling layer. This keeps media capacity separate from the web and XMPP tiers. Plan for the bridge count you need at peak, and confirm with your architects how Jicofo distributes conferences across bridges in your topology. Recording with Jibri needs its own capacity planning.
BigBlueButton's published host baseline
BigBlueButton 4.0 is documented for Ubuntu 24.04 with 16 GB of memory, 8 CPU cores and 500 GB of disk for recordings. Those figures describe a single host that carries the whole teaching stack. Size the server before you buy it, and treat the disk figure as a floor that grows with recording retention. Confirm current requirements in the install documentation before each rollout.
Port planning and web server conflicts
BigBlueButton needs UDP 16384 to 32768 for media and TCP 80 and 443 for the web front end, and those web ports must not be used by another web server. Coexisting with an existing intranet or reverse proxy on the same host is therefore a design decision, not a default. Check firewall rules, NAT and load balancer policy against this range before the pilot. Jitsi's ports and proxy layout should be reviewed the same way.
Patching and recording storage
Jitsi patches are spread across several services, so your change process must cover the videobridge, Jicofo, Prosody and any Jibri nodes together. BigBlueButton bundles more functions per host, so one upgrade touches more of the teaching stack at once. Recording storage is a recurring cost: decide retention, backup and deletion rules before you enable recording. Confirm upgrade paths for each platform with its release notes.
Confirm multi-server options
The supplied material documents BigBlueButton's single-host requirements, but it does not establish how or whether that stack scales across several servers. Before you size a multi-server design for high concurrency, ask the vendor or check the BigBlueButton documentation for supported clustering or horizontal options, and get the answer in writing. Compare that answer with the bridge model Jitsi uses when you build your capacity estimate.
Jitsi vs BigBlueButton feature by feature
This table compares the two projects row by row on licensing, release references, architecture, recording, dial-in, teaching features, scale-out and identity. Where the researched facts do not settle a row, the cell tells you what to confirm before you commit, so treat blank-looking gaps as open questions rather than missing features.

What licensing and paid options cover for each platform
Jitsi Meet is licensed under Apache-2.0. The latest stable release tag in the supplied facts is stable/jitsi-meet_11248, published on September 14, 2026. Jitsi Meet is self-hosted inside your own cloud accounts, data centers or air-gapped networks, and the supplied facts name no paid Jitsi Meet edition. Apache-2.0 is a permissive license, so you can run, modify and redistribute the code, including inside closed products, as long as you meet its conditions.
- Keep the license and notices: When you redistribute Jitsi Meet, include a copy of the Apache-2.0 license and keep the copyright and attribution notices present in the source.
- Mark changed files: Modified files should show that you changed them, and any NOTICE file content in the source should travel with your distribution.
- Patent terms: Apache-2.0 includes an express patent license from contributors that can end if you bring a patent suit over the software, so review that clause with counsel before you build a product on it.
- Commercial support: The supplied facts do not name a commercial support contract, hosted service or consulting offer for Jitsi Meet.
Before you commit, confirm with your legal team how your deployment and any redistribution map to these conditions.
BigBlueButton is licensed under LGPL-3.0, and its project describes its mission as building the most effective virtual classroom. The supplied release history includes v4.0.0, published on October 14, 2026, and v3.0.39, published on October 2, 2026. As with Jitsi Meet, the supplied facts name no paid BigBlueButton edition or hosted offering. LGPL-3.0 is a weak copyleft license, so its strongest obligations apply to the library-level code you change and the way you deliver it.
- Modified LGPL components: If you change LGPL-licensed code and distribute the modified version, you must make that modified source available under LGPL-3.0 terms.
- Linking and combined works: Software that links to BigBlueButton components can often keep its own license, but the exact boundary depends on how components are combined, so confirm it with counsel.
- Internal use: Running modified code only inside your organization is generally not treated as distribution under the license, but confirm how your own use case is classified.
- License text and source: Ship the license text and notices with any binary, appliance or image you distribute, and keep the source for each version you deploy available for audit.
Check the LGPL-3.0 terms against your specific build and deployment model before you customize the code.
Neither project's supplied facts name a paid edition, so support, hosted operation and upgrades are contracted separately. Depending on your situation, that work may come from a vendor or project maintainers if they offer it, from a managed hosting provider, from a systems integrator, or from your own team. The license terms do not answer these questions, and they often drive more of the total spend than the license does.
- Who supports the code: Confirm whether the Jitsi or BigBlueButton maintainers, or any third party, offer paid support, and what that support covers.
- Hosted offerings: Ask whether any provider runs either platform as a managed service, and where your meeting recordings and metadata would be stored.
- Upgrade ownership: Define who applies releases, such as Jitsi Meet stable tags or BigBlueButton major versions, and who tests them before production.
- Written scope: Ask for a written scope that lists versions, components, environments and response expectations, since that scope determines effort more than the license does.
Confirm these points before comparing budgets, because licensing is not the main variable here and support and operations are.
What drives the running cost of each platform
The running cost of either platform is set less by license fees, since both Jitsi Meet (Apache-2.0) and BigBlueButton (LGPL-3.0) are free to self-host, and more by the servers, storage, staff time and upgrade work the deployment consumes. For BigBlueButton, the published install baseline for version 4.0 is 16 GB of memory, 8 CPU cores and 500 GB of disk for recordings, per its install documentation. That is one server sized for the whole stack, so cost rises in steps when you need more concurrent classes, and recording storage grows with every session you keep. Jitsi splits its work across the Jitsi Videobridge media router, the Jicofo conference focus and the Prosody XMPP signalling server, so the media tier can grow by adding bridges as load increases. Ask the vendor or your implementer to show the expected bridge count for your peak concurrency before you assume the Jitsi layout is cheaper.
Staff cost is the largest recurring line in most self-hosted video estates, and it differs by platform. A Jitsi deployment needs people who can operate several cooperating services, tune bridge capacity, and manage optional Jibri recording or Jigasi SIP dial-in if you enable them. A BigBlueButton deployment is a more integrated appliance-style install, but it needs someone who can handle its server sizing, port layout and recording pipeline. Patch and upgrade effort recurs for both: each major or minor release, along with the operating system and database layers beneath them, must be tested and rolled out. One-time costs include the initial install, integration with your identity provider, TLS and network configuration, and load testing. Recurring costs include hosting, storage growth, patching, monitoring and any support contract. Confirm in writing who owns each of these, and whether a retainer covers upgrades and continuous testing.
A written quote should make these cost drivers explicit. Specify the scope (video meetings, classroom features, recording, SIP dial-in, identity integration), the environments (production, staging, and any air-gapped or multi-region setup), the concurrency target in simultaneous participants and simultaneous rooms, the recording retention period and where recordings are stored, and who owns upgrades and how often they are scheduled. Ask for the server and storage assumptions behind each figure, the one-time versus recurring split, and what changes the price if concurrency or retention grows. Fixed-scope engagements agree these items in writing before work starts, so a quote without them is hard to compare across vendors.
Moving users from Jitsi to BigBlueButton or back
This sequence moves meeting users, scheduled rooms and recording archives between Jitsi and BigBlueButton without losing track of what each platform can carry across. It ends with the old service retired and users pointed at the new one.
Inventory current meeting and recording use
The team that runs meetings lists every active room, who books it, how often it is used, and whether anyone depends on recordings, live streaming, or SIP dial-in. Include external guests and any teaching workflows that rely on shared slides, polls, or breakout rooms. Recording owners should record where archives live and how long they are kept. The output is a written inventory with one row per room type, owner, and dependency. You know it is done when the platform owners sign off that nothing in use is missing from the list.
Confirm identity and room-access requirements
The identity owner documents how people sign in today, whether rooms are open to anyone with a link, whether moderators need authenticated accounts, and which guests join without accounts. Compare these needs with what each platform supports in its published documentation, and confirm any gap, such as single sign-on or moderator controls, with the vendor before committing. The output is a short access policy stating who may create rooms, who may join, and how guests are admitted. It is done when the security owner has approved the policy against the target platform.
Build the target environment to published requirements
The platform engineering team builds the target server from its install documentation. For BigBlueButton 4.0, the published requirements include Ubuntu 24.04, 16 GB of memory, 8 CPU cores, 500 GB of disk for recordings, UDP ports 16384 to 32768, and TCP ports 80 and 443 free from another web server. For Jitsi, the team confirms the videobridge, conference focus, and XMPP signalling components, and adds bridges if concurrency needs it. The output is a documented build with network paths tested from both inside and outside the network. It is done when a test meeting completes with audio and video from at least two external networks.
Pilot with a small group
Choose a small set of users and a few representative room types, such as a weekly team meeting and one recorded session. Run them on the new platform for a fixed trial period agreed in advance, and collect feedback on audio, screen sharing, moderator controls, and recording playback. Keep the old service running in parallel. The output is a pilot log listing defects, workarounds, and client settings that users needed. It is done when the open defects are either fixed or accepted by the owner in writing.
Migrate scheduled rooms and recording archives
Rebuild the scheduled rooms on the target platform, then copy recording archives that the team has decided to keep. Neither platform's migration tooling is named in the supplied facts, so the migration lead should ask the vendor which export and import options exist for room definitions, user lists, and recordings, and whether links can be preserved. Where no import path exists, archive recordings in their original format and store them under the retention rules from step one. The output is a mapping sheet from old room to new room, with recording locations recorded. It is done when a sample of migrated recordings opens correctly and every mapped room has a named owner.
Rebuild configuration, integrations and client guidance
Some items will not transfer and must be rebuilt by hand. These include room-level settings, calendar or portal integrations, dial-in numbers, and any SIP gateway that the old service used. The support team also rewrites client guidance for the new join flow, including supported browsers and what to do when a meeting link has changed. The output is a rebuilt integration list with an owner for each item and a published user guide. It is done when each integration has passed a test call and the guide has been reviewed by the pilot group.
Retire the old service
Announce a cutover date to all users, redirect old links to the new service where the platform allows it, and disable new room creation on the old service. Keep the old environment in read-only mode for a period the owner sets, so any missing recording can still be retrieved. Then decommission it and remove its firewall rules, DNS records, and certificates. The output is a retirement record listing what was removed and where archives now live. It is done when the old service no longer accepts connections and the record has been signed by the service owner.
How Jitsi and BigBlueButton implementation projects run long
Most overruns on either platform trace back to two decisions made late: the concurrency target and the network path. For Jitsi, the media path decides the schedule. The Jitsi Videobridge carries the media, Prosody handles signalling, and Jicofo allocates conferences, so the firewall plan must allow the media traffic to reach the bridges directly, not only the web front end. Confirm with your network team which UDP paths are permitted between clients and bridges, and whether TURN relays are needed for users behind restrictive corporate networks. For BigBlueButton, the same risk shows up as ports: the install documentation calls for UDP 16384 to 32768 and TCP 80 and 443 not used by another web server. A reverse proxy or shared web server on the same host is the most common surprise. Check port availability and proxy design before ordering hardware, and record who owns each firewall rule.
Concurrency targets and recording storage are the next two sources of rework. Ask the business to state the peak number of simultaneous participants, the number of concurrent meetings, and whether recordings or streams are required. Jitsi scales by adding bridges, so the design question is how many bridges and how Jicofo distributes conferences across them, and whether Jibri hosts are needed at all. BigBlueButton scales by server sizing, and its 4.0 install guide sets a minimum of 16 GB of memory, 8 CPU cores and 500 GB of disk for recordings. Recording storage sized after go-live usually means a disk expansion or a retention policy decided under pressure. Size storage from retention rules and expected class volume, and run a load test against the target concurrency with the real network path, not a single test host.
Identity integration and user training are the decisions most often discovered after go-live. Decide early how users authenticate, whether guests may join without an account, how moderator roles are assigned, and whether TLS certificates and identity providers must be integrated into the platform's configuration. These choices change configuration files, deployment steps and test scripts, so they should be fixed in the written scope with DeployOpen or your internal team before build starts. Plan user training for moderators and teachers separately from attendees, and schedule a pilot with the actual proxy, certificates and recording policy in place. Ask any implementation partner to confirm these items in writing, including which tests will prove each one works.
Questions buyers ask before choosing Jitsi or BigBlueButton
What does a Jitsi or BigBlueButton implementation cost, and what drives the price?
The cost is the written scope of work, not a fixed product price. Both platforms are open source, so no license fee applies to the software itself, but you pay for the people who plan, install, integrate, harden, back up and document the deployment. The main drivers are the number of servers and network changes, whether you need recording, SIP dial-in, single sign-on or LMS integration, how much hardening your security team requires, and whether you want ongoing support or upgrades under a retainer. Recurring costs are the infrastructure you run and any support retainer. DeployOpen does not publish a price list. Ask any provider for a quote built from a written scope that lists each component, the environments covered, and which items are one-time and which recur.
How long does a self-hosted video meeting deployment take?
The timeline depends on the platform you choose, the hosting environment and how much integration you need, so no single duration applies to both. A basic Jitsi Meet setup has fewer required services than a full BigBlueButton server, while BigBlueButton 4.0 has published hardware and network prerequisites that must be in place before installation starts. The factors that most often extend the schedule are firewall and port approvals (BigBlueButton needs UDP ports 16384 to 32768 and TCP ports 80 and 443 free of another web server), certificate and DNS work, identity integration, load testing and the approval steps in your change process. Ask for a timeline in the written scope that names the milestones and the client-side dependencies.
What does the work need from our internal team?
Expect to supply people who own the infrastructure and the decisions, even when an outside firm does the build. You will need someone who can provision the hosts or cloud accounts, a network owner for firewall rules and public DNS, an identity owner if you plan single sign-on, and a representative who can approve the security baseline and the operating procedures. For BigBlueButton, the install documentation calls for Ubuntu 24.04, 16 GB of memory, 8 CPU cores and 500 GB of disk for recordings per server, so a capacity owner should confirm that budget before work begins. Ask the provider which of these roles they expect you to fill and how many hours of your staff time the scope assumes.
Can our own team deploy Jitsi or BigBlueButton without outside help?
Yes, a capable internal team can deploy either platform, because both are open source and documented publicly. The question is whether your team can carry the work to production and keep it there. Jitsi Meet combines the Jitsi Videobridge, Jicofo, Prosody and optional Jibri and Jigasi components, so you need people who can operate that chain and scale it by adding bridges. BigBlueButton is a larger single stack that benefits from a dedicated server and a tested upgrade path. Consider your on-call coverage, your hardening standard, your backup and restore testing, and your upgrade cadence, since the BigBlueButton 4.0 release on October 14, 2026 and the 3.0.39 release on October 2, 2026 show that maintained lines change over time. A written scope can cover some of this work while your team retains operational ownership.
Can BigBlueButton replace Jitsi for virtual classrooms?
BigBlueButton is the platform built for virtual classrooms, and it is usually the better fit when teaching features such as shared presentations, breakout rooms and session recording matter to your program. Jitsi can host general meetings and can add recording through Jibri, but it is not designed around a classroom workflow, so confirm the specific features your instructors need before deciding. In the other direction, BigBlueButton is heavier to run, so it may be more than a general meeting service needs. Test the classroom features your instructors use on a staging server with the real session length and participant count, and confirm what each platform supports in the current release notes and documentation.
How should we plan concurrency for video meetings?
Plan concurrency from the number of meetings that run at the same time and the participants in each, then size servers for that peak. Jitsi scales out by adding Jitsi Videobridge instances, so capacity grows with the number of bridges you deploy, and the signalling and focus components need their own sizing. BigBlueButton runs as a dedicated server with published minimums (16 GB of memory and 8 CPU cores for version 4.0), so a larger peak usually means more full servers and a plan for how meetings are assigned to them. Ask the provider to load test with your expected peak, record the results and write the scaling procedure into the scope, and confirm current limits in each platform's documentation before you commit to a hosting budget.
How DeployOpen helps choose, implement or move between video platforms
DeployOpen plans, implements, integrates, hardens, backs up, documents and supports self-hosted open-source platforms inside your own infrastructure, whether that is your cloud account, data center or air-gapped network. For video, that means matching the platform to the meeting pattern you actually run, then building it so your operations team can keep it running after handover.
How we scope
- We confirm whether you need general video meetings, a virtual classroom, or both, before comparing deployment options.
- The written scope lists concurrency targets, recording or streaming needs, SIP dial-in, and the hosts that will run each component.
- Engagements are fixed-scope, so deliverables and timelines are agreed in writing before any build work starts.
How we build
- We deploy the chosen stack in your environment, including media routing, signalling, identity integration and TLS configuration.
- For Jitsi, we size additional videobridge capacity against the concurrency targets in the scope and test how it scales out.
- For BigBlueButton, we check the server specification, port layout and storage for recordings against your hosting plan before installation.
How we hand over
- We document the architecture, configuration, backup and upgrade steps so your team can operate the platform without us.
- Security testing of the deployed service can run before go-live, with findings tracked to resolution in the handover pack.
- Handover covers the evidence and controls your compliance assessors may ask for, which independent auditors then evaluate.
How we support
- Ongoing support, upgrades and continuous testing are available as a retainer after handover.
- Retainers can cover tracking new Jitsi and BigBlueButton releases, applying them in a test environment, and rolling them out.
- Ask any quote to name the support hours, response expectations and the components covered, so scope stays clear.
