Cosh – a terminal-native coding agent written in Rust
Single-binary Rust coding agent with a streaming TUI, background subagents, multi-provider support (Claude, OpenAI, Gemini and more), and OAuth 2.0 device sign-in for GitHub Copilot and Charm providers.
Why it matters
Boots in milliseconds with no runtime dependencies and never truncates context — a bring-your-own-model terminal agent that stays usable offline.
What you could build with it
An indie developer on a low-RAM laptop could install cosh's single Rust binary and point it at a cheap model endpoint for everyday coding tasks; the concrete result is a fast terminal coding assistant with no subscription lock-in and context that survives long sessions.
Does it hold up?
Too early to judge for stability — v0.1.0 shipped 2026-10-01 and v0.1.3 on 2026-10-04 (four releases in four days), but the repo (created June 2026) still has 0 stars. Apache-2.0 licensed; installs via one curl command on Linux/macOS or irm on Windows.
