KeePassDiff 2 - 🚧 Inviting Testers (Open Beta)

Diff & Merge Tool for KeePass Databases

KeePassDiff 2 is a modern desktop application for comparing and merging two KeePass (.kdbx) databases.

It is the successor to the original KeePassDiff web-based tool. While the original focused on quick comparisons, KeePassDiff 2 is designed for long-term, real-world use (especially when KeePass databases have drifted out of sync over time). The goal is to provide an intuitive, git-like diff and merge experience.

🚧 Inviting Testers (Open Beta)

🚧 KeePassDiff 2 is currently in early testing, and I’m inviting users to try it out and share feedback.

If you:

• Maintain multiple KeePass databases
• Sync databases across devices or systems
• Have dealt with merge conflicts or missing entries

…your feedback would be extremely valuable.

What I’m looking for

• Bug reports
• UX feedback
• Edge cases (large databases, long-out-of-sync histories)
• Suggestions for diff and merge behavior / more advanced features

How to help

• Test using non-critical or backed-up databases
• Report issues via GitHub Issues / X
• Include steps to reproduce, logs, or screenshots if possible

[!Important] We don't write to original databases. But still, since we are in beta, keep backups before testing.
