Brew Chai CLI is public: free for individuals, Pro for teams.

Brew Chai has been our internal tool for most of its life: the layer we use on top of Claude Code, Cursor, and OpenCode while we ship our own products. Today it's installable for everyone. One curl, one binary, signed-prompt fetches over Cloud Run. Free Forever for individual non-commercial work; Pro at €49 / seat / month for teams.

one curl · five platforms · code stays local

One install drops the full CLI on macOS, Linux, and Windows. The CLI fetches signed prompt packages from a Cloud Run backend; your code never leaves the machine.

The two tiers, plainly

One question shapes the divide: does this command read or does it write? Free runs the read-side and the small fixes. Pro runs the autonomous build pipeline.

Free Forever

€0individual · non-commercial

Audits (a11y, perf, SEO), repo diagnostics, dev-environment plumbing, knowledge ops, and bounded /brew for fix-class and tool-class intent, 10 runs per calendar month.

Pro

€49/ seat · month + VAT

Everything above, plus the autonomous build and heal pipelines: sprint planning, parallel agent worktrees, audit-fix loops with severity gates, the design and UI test suites, browser automation, and Ralph mode for unattended runs.

How upgrade works

Run brew-chai login --tier=pro. Your browser opens, Stripe Checkout collects card and VAT info, payment confirms, a Pro key is issued back to the CLI inside the same terminal session. The login window holds 20 minutes so you have room for VAT lookups; the Stripe Customer Portal handles cancel, seat changes, and invoices.

$ brew-chai login --tier=pro
  → opening browser for Stripe Checkout
  → waiting for confirmation (20m timeout)
✓ pro key issued · 1 seat · invoice INV-2087-A

Code stays on your machine

The architectural commitment is unchanged from the internal version. The CLI fetches a signed prompt package: prompt ID and API key only, never code content. Inference runs through whatever AI IDE is already on the developer's box (Claude Code, Cursor, OpenCode, Continue, Windsurf, aider, your tokens, your provider). The Brew Chai backend never sees the repository.

Enterprises that want zero outbound dependency can self-host the prompt backend behind their firewall, the dead-drop guarantee covers them either way.

One install. Forty-eight agents. Thirty-five workflows. Free reads. Pro writes.
