Hydra is an open-source (Apache 2.0) desktop terminal built for AI coding agents. It finds the agent sessions already on your machine - Claude Code, Codex, Copilot, Cursor and more - and shows them all on one dashboard, with a full lifecycle: rename, hide, stash, revive.
Automatically tiles and organizes all terminal sessions in one native macOS window, scaling layouts from fullscreen to grid, grouping sessions by project with color-coding, enabling instant filtering, supporting any CLI tool, and requiring zero configuration.
Australia
A desktop app for isolated, parallel agentic development.
