atuinsh/atuin

Atuin is a command-line history and shell integration tool that captures, stores, and searches command-line history across multiple shells. It features a background daemon that provides fast, in-memory fuzzy search and semantic command capture, while the server component supports self-hosting with either SQLite or PostgreSQL backends. The system manages user accounts, synchronizes encrypted records, and handles shell configuration such as aliases and environment variables.

How it got here

2020–2024 · Daemon, workspace, and shell integration

The project underwent a major architectural shift to a multi-crate Cargo workspace, introducing a background daemon for in-memory search and command capture. This period also added comprehensive shell integration for multiple shells, expanded dotfiles management, and established a flexible server database abstraction.

2025–2026 · Daemon architecture and search overhaul

This period focused on introducing a new daemon component to handle history capture, search, and synchronization, alongside a complete rewrite of the search interface with an extensible keybinding system. The backend was modernized with a self-hosted SQLite server option and a capability negotiation protocol for client-server compatibility. Additionally, local AI session storage and script execution features were added to the client.
