Both are open source alternatives to LastPass. We compare license, tech stack and features to help you decide which fits your team best.

Bitwarden (self-hosted) has more GitHub stars, which usually indicates a larger community (not necessarily that it's the best option for your use case).
Bitwarden (self-hosted)
Official self-hosted Bitwarden server, a complete alternative to 1Password.
ℹ️ Bitwarden migrated its official self-hosting image from bitwarden/self-host (Docker Hub) to ghcr.io/bitwarden/lite (a single container). We've updated the image and version, but haven't verified the new container's environment variables one by one — check Bitwarden's official deployment guide before running this in production.
Pros
- It's the official server, with direct support from Bitwarden
Things to consider
- Considerably heavier on resources than Vaultwarden
KeeWeb
Web client for KeePass vaults, a lightweight alternative to LastPass.
Pros
- Builds on the KeePass format, very mature and well-audited
Things to consider
- It's a client, not a server: sync depends on another backend
