Atlas

Atlas is a coding-agent harness for the terminal — not a wrapper around someone else's harness. The agentic loop is ours: raw LLM calls through the Vercel AI SDK, with full control over what context the model sees, which tools it may call, when a human is asked, and what happens on rewind. Model-agnostic by construction — Claude and Codex subscription credentials are one provider implementation among several.

Built with OpenTUI, React, and Bun. Ships as a single compiled binary.

Install

curl -fsSL https://install.byatlas.io | bash

No GitHub auth needed — the script verifies the sha256 and puts atlas at ~/.local/bin; the binary self-updates from then on. To run from source instead:

bun install
apps/tui/bin/atlas-dev

Developing

See CONTRIBUTING.md for setup, the dev loop, and the PR flow. The architecture lives in docs/architecture.md.
