Brew Chai is open source.

One install drops the full plugin tree on macOS, Linux, and Windows. Everything runs on the developer's box through whatever AI IDE is already there: Claude Code, Cursor, OpenCode, Continue, Windsurf, aider. Your tokens, your provider, your repository. Nothing about your code is sent to us.

$ curl -fsSL https://creativehuman.ai/brew-chai/install.sh | bash
✓ brew_chai installed
$ /brew "add rate limiting to the public API"
→ plan · critique · sprints · tasks · parallel worktrees · audits · PR

What is in the box

• 48 agents, each with one job: planning, critique, sprint decomposition, implementation, audits for security, performance, accessibility, hygiene and craftsmanship, and the mergers that bring parallel worktrees back together.
• 35 commands. /brew runs the whole pipeline: one question round up front, then silence until a tested branch is handed back with every gate on record.
• The prompts are plain files. Read them, change them, send the change back.

Why open source, and why no paid tier

The value of an orchestration layer is in the prompts and the gates, and those get better fastest when the people who run them every day can read and improve them. A tier line would put the best of the pipeline behind a wall, and the pipeline is the argument. So there is none. Brew Chai is MIT, whole, for individuals and companies alike.

Code stays on your machine

The architectural commitment is unchanged from the internal version. Inference runs through the IDE on the developer's box. There is no Brew Chai backend that sees a repository, because there is no Brew Chai backend.

One install. Forty-eight agents. Thirty-five workflows. MIT.
