Bitbucket Cloud vs Data Center vs Server: Complete Comparison 2026

Bitbucket Cloud vs Data Center vs Server: Complete Comparison 2026

If you're navigating Atlassian's Bitbucket ecosystem in 2026, you're facing a critical decision: Bitbucket Cloud (SaaS), Bitbucket Data Center (self-managed enterprise), or migrating away from the now-discontinued Bitbucket Server. This guide compares all three to help you choose the right platform for your team.

TL;DR: Key Takeaways

• Bitbucket Server reached end of life (EOL) in February 2024: no more security patches or updates
• Bitbucket Cloud is Atlassian's SaaS offering (managed by them, pay per user)
• Bitbucket Data Center is self-managed enterprise software (you host it, full control)
• Migration urgency: If you're still on Server, migrate to Cloud or Data Center ASAP
• AI code review works on all platforms with Git AutoReview

The Bitbucket Landscape in 2026

Atlassian has reshaped its Bitbucket offerings over the past few years. Here's what happened:

2022: Server EOL Announcement

Atlassian announced Bitbucket Server would reach end of life on February 15, 2024, giving customers two years to migrate to Cloud or Data Center.

2024: Server EOL Date

As of February 15, 2024, Atlassian stopped providing:

• Security patches and bug fixes
• Feature updates
• Technical support for Server instances
• License renewals for new customers

2026: Current State

• Bitbucket Cloud is Atlassian's primary SaaS offering with continuous updates
• Bitbucket Data Center serves enterprise customers with on-premise requirements
• Bitbucket Server instances still run but are increasingly risky due to unpatched vulnerabilities

Bitbucket Server End of Life: What It Means

If you're still running Bitbucket Server in 2026, here's your situation:

What Stopped Working

• Security updates: New CVEs won't be patched
• Bug fixes: Known issues won't be resolved
• Compatibility: New Git features won't be supported
• Support: Atlassian support teams can't help with Server issues
• License renewal: New Server licenses are unavailable

Why This Matters

• Security risk: Unpatched vulnerabilities accumulate over time
• Compliance violations: SOC 2, ISO 27001, and GDPR audits often require current software
• Technical debt: Integration issues with modern tools increase
• Team morale: Developers expect modern tooling

Migration Timeline

Most organizations take 3-6 months to fully migrate from Server to Cloud or Data Center. If you haven't started yet, begin immediately.

Frequently Asked Questions

Is Bitbucket Server still supported?

No. Bitbucket Server reached end of life on February 15, 2024. Atlassian no longer provides security patches, bug fixes, or technical support.

Can I still use Bitbucket Server?

Your instance will continue to run, but you won't receive security updates. This creates increasing risk as new vulnerabilities are discovered.

How much does it cost to migrate from Server to Cloud?

Cloud pricing is $15-30/user/month. Migration itself is free using Atlassian's migration tools, but you'll need to budget staff time (typically 3-6 months of planning and execution).

Does Git AutoReview work on all Bitbucket platforms?

Yes! Git AutoReview supports Bitbucket Cloud, Server (during migration), and Data Center. It's the only AI code review tool with full Bitbucket coverage.

Can I migrate from Cloud to Data Center later?

Yes, but it's more complex than Server to Cloud migration. You'll need to export data from Cloud and import to your Data Center instance. Plan for 2-4 months.

What happens to my Bitbucket Server license after EOL?

Existing licenses continue to work, but Atlassian won't renew or issue new Server licenses. You must migrate to Cloud or Data Center.

Conclusion

The Bitbucket landscape in 2026 is clear:

• Bitbucket Server is dead (EOL Feb 2024) — migrate immediately
• Bitbucket Cloud is the right choice for most teams (simplicity, managed infrastructure)
• Bitbucket Data Center is essential for enterprises with on-premise requirements

For AI code review, Git AutoReview is the only tool that fully supports all three platforms. Whether you're on Cloud, Data Center, or migrating from Server, you get the same human-in-the-loop workflow, multi-model AI, and BYOK privacy.
