vaultwarden
Unofficial Bitwarden-compatible password manager server written in Rust, optimized for self-hosted deployment.
What is vaultwarden?
Vaultwarden is an unofficial, open-source server implementation of the Bitwarden password manager API, written in Rust. It provides a lightweight, resource-efficient alternative to the official Bitwarden server, enabling users to self-host their password vault with full compatibility across all Bitwarden clients. It solves the problem of running a heavy server by offering a minimal footprint while maintaining feature parity.
Individuals, families, and small organizations who want to self-host a password manager with full control over their data, using existing Bitwarden clients. It's ideal for users with limited server resources or those prioritizing privacy and data sovereignty.
Developers choose Vaultwarden because it offers a significantly lighter resource footprint than the official server, making it perfect for self-hosting on low-power hardware like Raspberry Pis or small VPS instances. It maintains full Bitwarden client compatibility, ensuring a seamless user experience without vendor lock-in.
