Crush
Charm's terminal coding agent — beautiful TUI, source-available license.
About
Crush (charmbracelet/crush, ~28.6k stars) is Charm's terminal coding agent with the signature Charm TUI polish: multi-model support, MCP, sessions, and a plugin system.
License caveat: it uses the Functional Source License 1.1 (MIT Future License) — source-available, converting to MIT two years after each release. You can read and self-host it, but it is NOT OSI open-source; commercial redistribution terms differ from MIT. Flagged clearly here so there are no surprises.
