Open-source alternative to Google Drive

Open-source alternative to Google Drive: the short answer

If your renewal, data residency rule or lock-in concern centers on Google Drive and shared drives, Nextcloud is the broadest fit, Seafile suits sync-heavy teams that mostly move large libraries between desktops, and ownCloud Infinite Scale (oCIS) suits large or Kubernetes-first deployments where a single binary of microservices, S3 or NFS storage and Helm charts match how the platform team already operates. Which of these is right depends less on features than on team size, the volume of data that syncs to laptops, and whether your administrators want a PHP application stack or a Go-based service they can deploy on Kubernetes. The short answer does not settle browser editing. Real-time editing of Word, Excel and PowerPoint files in a browser is a separate component, usually Collabora Online or ONLYOFFICE, connected to the file platform through WOPI or a similar integration. Nextcloud, Seafile and oCIS all document connections to one or both, so test the editor with your own shared drives and permission model before you commit. Decide early whether users need co-editing in the browser, offline sync only, or both, because that answer changes the sizing, the upgrade plan and the support contract you will need. This page covers file storage, sync, sharing and permissions only. It does not cover Gmail, Google Docs, Sheets or Google Chat, which have their own alternative pages. For the Drive side of a Workspace exit, check first which Drive exports you can produce from the admin Data Export or per-user Takeout, since those files and sharing links drive the migration effort more than the choice of platform does.

Which Drive capabilities map to which open-source platform

This table maps the main Google Drive capabilities to Nextcloud, Seafile and ownCloud Infinite Scale (oCIS). Read each row as a starting point, and confirm version history depth, audit logging and retention in each platform's current documentation before you decide. The main takeaway is that packaging differs, so the edition, app or license tier behind each cell matters as much as the platform name.

Nextcloud, Seafile or ownCloud Infinite Scale: when each fits

All three platforms sync files to desktop and mobile clients, support sharing and permissions, and run inside your own infrastructure. They differ in licensing, in how paid support is sold, and in how much of a file workflow they cover out of the box. The cards below describe where each one tends to fit a team replacing Google Drive and shared drives.

Nextcloud for broad file workflows

Nextcloud Server is licensed under AGPL-3.0-only, and Nextcloud GmbH sells Enterprise subscriptions for support and extra features. Its app ecosystem covers calendar, contacts, Talk for calls and chat, and browser editing through Collabora Online, so teams replacing Drive and Docs together usually start here. The All-in-One installer bundles the database, caching, backups and antivirus for smaller deployments. Check which apps you depend on, because the upgrade path requires moving one major version at a time and third-party apps must be confirmed compatible before each step.

Seafile for library-based sync

Seafile organizes files into libraries that sync separately, and each library can be encrypted with a password chosen by its users. This suits teams that want clear boundaries between departments or projects and want sensitive libraries protected beyond server-side storage. The Community Edition is AGPLv3, while Professional adds SAML 2.0, multi-tenancy, role-based permissions and advanced search. Confirm whether your use needs those features, and what Seafile's commercial terms are for support beyond the free Professional use for up to 3 users.

ownCloud Infinite Scale for storage flexibility

oCIS ships as a single Go binary of microservices under Apache-2.0, with no external database needed for basic deployments. It supports S3, NFS and PosixFS storage backends, which matters if your files already sit on an object store or a shared filesystem. Helm charts make it practical on Kubernetes, and it can use the embedded identity provider or an external OpenID Connect provider such as Keycloak. Its browser editing works through WOPI with Collabora Online or ONLYOFFICE, so confirm your Office integration early.

How team size and browser editing change the choice

When people mainly need to sync folders, share files with partners and keep control of where data sits, the simplest self-hosted setup is usually the best starting point. Seafile is a strong candidate here because it organizes files into libraries that sync separately and can each be encrypted with a user-chosen password. Its Community Edition runs on generic Linux, and Docker single-node setups are documented. Nextcloud is equally reasonable if the team also wants calendars, contacts and talk features in one place.

Library model: Seafile's separate libraries map cleanly to project folders and make access boundaries easy to explain.
Free tier limits: Seafile Professional Edition can run without a license file for up to 3 users, so confirm which edition the team actually needs.
Sync clients: Test the desktop client on your largest folder, including first-sync time and conflict handling.
Operating effort: A single node with regular backups is a reasonable target for a team without a dedicated platform group.

Confirm the user licensing terms for your edition and how the vendor's support options map to your internal capacity.

How sharing and permissions work after leaving Drive

The first decision is who owns the files. In Google Drive, a shared drive belongs to the organization, but individual files and link shares often trace back to the person who created them, so a departing employee can quietly leave gaps. On a self-hosted platform, plan ownership around team folders or groups instead of named users. In Nextcloud, group folders and shares can be set up so the folder outlives any one account. In Seafile, libraries are owned by a user, so confirm how ownership transfers before a departure. In ownCloud Infinite Scale, spaces are the closest counterpart to shared drives, and you should confirm how their manager roles are assigned and reassigned in your version. Map each Drive shared drive to one of these structures before migrating any content.

Access control should come from your directory, not from manual sharing. Nextcloud's LDAP app lets LDAP and Active Directory users log in with their directory credentials, and Nextcloud also documents OpenID Connect and SAML backends, so group membership can drive folder access. Seafile supports LDAP, Active Directory and several single sign-on options, and its Professional Edition adds SAML 2.0 and role-based permissions. oCIS can use its embedded identity provider or an external OpenID Connect provider such as Keycloak. Confirm which group attributes each platform reads, how nested groups are handled, and how deprovisioning removes access to shared folders. Do not assume that a Drive link share, an expiring link or an "anyone with the link" setting has a one-to-one equivalent. Test each sharing pattern you rely on with a pilot group before you commit.

Plan the link shares separately. Public links, password protection, expiry dates and download restrictions are the controls most likely to differ between platforms and between editions, so ask each vendor or your implementation partner to show them working in your version. Export a sample of existing Drive permissions, group them by pattern, and assign each pattern a target: group folder, user share or link share with limits. Document the exceptions. Those decisions, not the file transfer, determine whether the new setup is safer than the old one.

Moving Drive files and shared drives to a self-hosted platform

This sequence moves Drive content into a self-hosted platform with ownership, sharing and permissions verified at each stage, so users can cut over to files they can trust. The output is a reconciled archive, mapped team folders and a documented cutover record.

Inventory shared drives and external sharing
The Workspace admin lists every shared drive, its owners and members, and every file or folder shared outside the organization, including link-sharing settings. Your migration lead records file counts and approximate sizes per drive, and flags orphaned files whose owners have left. The step is done when the inventory is signed off by the business owners of each drive and the external shares that must survive the move are marked.
Export Drive data within the retention window
Run the admin Data Export as a super administrator, or have individual users run Google Takeout where the admin has allowed it. Google's supplied facts say the admin account must be at least 30 days old, exports typically take about 72 hours but can take up to 14 days, and the default Cloud Storage bucket is deleted after 60 days. Download the archives to your own storage before the bucket expires. The step is done when every archive is downloaded and its size matches the export summary. The sibling export page covers the full procedure.
Reorganize content into team folders
Map each shared drive to a team folder or group folder on the target platform, and decide which legacy folder paths to keep. Remove duplicates and personal scratch files that no team owns. Convert native Google Docs, Sheets and Slides into office formats where the target editor needs them, and confirm the conversion path with your chosen office component. The step is done when a written folder tree is approved, with one owning team per folder.
Import with a scripted or client-based transfer
Load the reorganized files into the target platform using a scripted transfer over WebDAV, the platform's bulk import tooling, or a desktop sync client for smaller sets. Use a service account with the minimum rights needed for the import, and log each transfer batch. Confirm the storage backend (for example, S3-compatible object storage or local disk) has capacity for the full set plus growth. The step is done when every batch has a completed log entry and no transfer errors remain unresolved.
Map permissions and external shares
Recreate group memberships through the directory integration (LDAP, Active Directory, OpenID Connect or SAML, depending on your platform) rather than by hand. Translate Drive roles (owner, editor, commenter, viewer) into the target platform's share and permission model, and recreate external shares only where the business owner approved them. Remove public link shares that have no active owner. The step is done when a sample of files per team has been checked by a named owner, and the exception list is documented.
Validate checksums and file counts
Compare file counts and total sizes per folder between the export archive and the target platform, then compute checksums for a representative sample, or for all files if the set is small enough to verify in full. Investigate every mismatch, including files that Google converted during export. Record any intentional exclusions with the approving owner. The step is done when counts reconcile to zero unexplained differences and the validation report is stored with the migration record.
Cut over users team by team
Move teams in waves, starting with a pilot group, and announce a read-only freeze on each source drive before its final sync. Update bookmarks, desktop sync clients and any links embedded in internal documents or tools. Keep the Workspace drive accessible in read-only mode for an agreed period so users can check for missing items. The step is done when each wave has a signed cutover record and the support queue shows no open access issues for that team.
Retain the export archive under policy
Store the Data Export archives in an encrypted location that your records policy covers, and set a retention and deletion date that matches your legal and compliance requirements. Confirm with your compliance lead whether any regulated records need longer retention or a legal hold. Remove the default Cloud Storage bucket copies once your own copies are verified. The step is done when the archive has an owner, a documented retention rule and a deletion record for the source bucket.

Running self-hosted files alongside Gmail, Docs and Chat

Few organizations switch Drive, Docs, Gmail and Chat on the same day. This section covers four ways to run self-hosted files next to Google services while people move, and the two failure modes that appear in almost every phased move: broken links and duplicated files.

Keep Gmail and Calendar while moving files

Mail routing and file storage are separate decisions, so you can leave Gmail and Calendar in place while Drive content moves to Nextcloud, Seafile or oCIS. Users keep their mailboxes and invitations, and only file links change. Check that calendar invites and Gmail messages do not point to Drive files that will move later, and confirm that your identity provider can sign users into both systems during the overlap. Check whether your team relies on Drive previews inside Gmail, since those will stop working once the file is gone from Google.

Redirect Drive-era links to new URLs

Shared links, bookmarks and documents in Docs or Slack messages often point to drive.google.com addresses that stop resolving after migration. Build a mapping table from the Google file ID to the new path in your platform before cutover, then decide whether a redirect service or a published index page will serve old links. Test a sample of links from each team, because external collaborators may have granted access to a shared drive that is not carried over automatically.

Edit in Collabora while Docs stays

Teams that depend on Google Docs or Sheets can keep working there while files they host in Nextcloud or Seafile open in Collabora Online through the integration. Collabora edits .docx, .xlsx and .pptx files, but files saved back from Collabora are not Google-native, so Docs-native files still need conversion. Confirm which file types each team uses, how co-editing behaves when two people open the same file in different editors, and which version history the file carries after saving.

Phase the move team by team

Moving one team at a time limits the number of people working across two systems and makes support easier. Start with a team that has a clear folder structure and few external sharing links, then use that cutover to refine the export and import steps. Record for each team which shared drives, external partners and file types are in scope, and agree a date when the Google copy becomes read-only so that no one keeps saving to both places.

Avoid duplicated files

During a phased move, the same document can exist in Drive and in the new platform, and people will edit whichever copy they can find. Set a rule that each library has one owner and one active location, put the Google copy in read-only or archived state at cutover, and check for files modified in both places after each wave. Duplicates also inflate storage counts and complicate eDiscovery or retention, so review sizes and versions before you close each stage.

Questions buyers ask before replacing Google Drive

What drives the total cost of replacing Google Drive with self-hosted Nextcloud, Seafile or oCIS?

The total cost depends on five components: the platform (open-source software is free to download, but support subscriptions are not), storage capacity and its backend, the support tier you buy, migration labor, and ongoing operations. Platform licensing is usually the smallest recurring line for a team that runs its own servers, while storage and operations staff time scale with data volume and user count. Nextcloud Enterprise list prices are per user per year and start at a 100-user minimum, so ask any vendor or partner to show the license math against your headcount. Ask each quote to separate one-time migration work from recurring hosting, backups, upgrades and support hours.

Can our IT team self-host Nextcloud or Seafile without an implementation partner?

Many teams can run a single-node pilot themselves, because Nextcloud All-in-One and Seafile both document Docker-based setups. Production rollouts usually add identity integration, backups, upgrade planning and sharing policy, which need someone who knows the platform well. Nextcloud requires upgrades one major version at a time with a backup before each, so a team without that routine should plan for the work or buy support. DeployOpen plans, implements, integrates, hardens, backs up, upgrades and documents self-hosted platforms in your own infrastructure under fixed-scope agreements, with retainers available for ongoing support. Confirm which parts your staff will own after handover.

How long does a Google Drive migration take when data volume and permissions are complex?

The timeline depends mainly on data volume, the number of shared drives and sharing links, how many permission rules must be recreated, and how many native Google files need conversion. Transfer speed depends on your bandwidth and the target storage backend, so measure a representative sample before committing to a window. Nested folder permissions and external shares generally take more review than bulk copies of plain files. No fixed duration applies to your case, so ask for a timeline in the written scope that lists each phase, the sample size used for measurement and the acceptance criteria for permissions.

How do the Google Data Export and Takeout limits affect migration planning?

Data Export is run by a super administrator and delivers zip files to a Cloud Storage bucket. The admin account must be at least 30 days old, exports typically take about 72 hours but can take up to 14 days, and the default bucket is deleted after 60 days. Takeout is per user and depends on whether your administrator allows it. Plan the export window around those figures, copy the archives to your own storage before the bucket retention ends, and schedule a second delta export for changes made during cutover. Confirm these limits with Google for your edition before you set dates.

Which Nextcloud Enterprise tier or Seafile edition requires a paid license?

Nextcloud Server is free to self-host under AGPL, and Nextcloud Enterprise is a paid subscription for support and extra features. Its tiers are Standard, Premium and Ultimate, and the pricing page sets a 100-user minimum. Standard includes one year of maintenance, Premium adds a maintenance lifecycle of five or more years and clustered instance support, and Ultimate adds support up to 24/7. For Seafile, the Community Edition is open source, and the Professional Edition can run without a license file for up to 3 users. Features such as SAML 2.0, cluster deployment, multi-tenancy and advanced file search belong to Professional, so confirm which edition covers your requirements.

What must our internal team provide before a Drive replacement starts?

Your team should provide an inventory of shared drives, user and group records, the identity source (such as Active Directory, LDAP, OpenID Connect or SAML), retention and legal hold requirements, and named business owners who will approve permission mapping. You also need hosting capacity, network paths, backup targets and a decision on storage backend such as S3, NFS or Ceph. Assign someone to test restores and to accept each migration phase. Ask any partner to list these dependencies in the written scope so gaps surface before work begins.

Does moving off Google Drive change our security and compliance evidence?

Yes, because you take over controls that Google previously operated, including encryption key management, access logging, backup, antivirus and patching. Nextcloud All-in-One bundles ClamAV antivirus and BorgBackup-based backups, and oCIS and Seafile support LDAP or single sign-on, but each control still needs configuration and evidence. DeployOpen prepares systems, controls and evidence for compliance assessments, but it does not issue audit reports or certifications; independent auditors and certification bodies do. Ask your auditor which controls they will test and map them to your own environment early.
