Atuin

Atuin replaces your shell's history file with a SQLite database that records rich context for every command: the directory it ran in, how long it took, whether it succeeded, and which machine and session it came from. That context is what makes its full-screen search genuinely useful: you can query for all successful make commands after 3pm yesterday, or filter by exit code and working directory, instead of scrolling through a flat text file. History can sync across all your machines end-to-end encrypted, using Atuin's hosted Hub or your own self-hosted server, and your original shell history file is left untouched as a fallback.

The project is open source under MIT, written in Rust, and had over 32,000 GitHub stars with commits landing the day of this writing. Atuin Desktop, in open beta, adds executable runbooks that combine documentation with live shell commands, SQL queries, and HTTP requests. The honest caveats: sync is genuinely end-to-end encrypted, but your local history database is plaintext SQLite for search speed, so full-disk encryption matters; and losing your encryption key means losing synced history with no recovery. For terminal-heavy developers, it is one of the highest-value free tools in the ecosystem.

1. Install: curl --proto '=https' --tlsv1.2 -LsSf https://setup.atuin.sh | sh, then restart your shell.
2. Import existing history: atuin import auto.
3. Press Ctrl+R (or up arrow) for the full-screen history search UI.
4. Optional sync: atuin register -u <USERNAME> -e <EMAIL>, then atuin sync; back up your encryption key somewhere safe.
