Free OSS core for individuals and small projects. Team tier for orgs that want priority support and the advanced scanners. Both run entirely on your machine.
Everything in the open-source CLI. MIT-licensed; use commercially without restriction.

Brass scans your code and produces YAML files. It does not call an LLM on your behalf, does not resell tokens, and does not mark up Anthropic's pricing.
When you hand the .brass/ai_instructions.yaml output to Claude Code, Cursor, Continue, or any other AI assistant, you're using your own API access — not ours. Your bill from Anthropic stays the same; your bill from us is just the Brass subscription.
This is a deliberate choice. Bundling LLM credits into a thin tooling layer is bad economics for everyone — the user pays a markup, the vendor takes margin risk on token-price changes, and nobody knows where the money is actually going. BYOK keeps the lines clean.
Yes. MIT license. Use it inside your company, fork it, embed it in CI, ship a derivative — all fine. Attribution preserved per the license; no usage caps.
Refreshed quarterly. The current plan: deeper SAST coverage (Semgrep ruleset integration), JS/TS taint analysis, and an extended secrets pack covering enterprise-only formats (Okta, ServiceNow, internal SSO tokens). The OSS core never loses features — Team tier is additive.
License keys are issued and tracked by LemonSqueezy via their License API. Activation is a single HTTPS call from your machine to LS; afterward the CLI re-validates at most once per week to pick up cancellations or refunds. The actual scanning workflow (brassai scan, watch, filter) makes zero outbound calls — only the three license-management commands talk to LS.
No. One developer is fine; ten developers is fine. We don't punish small teams with a "five-seat minimum" that's really just a margin grab.
Cancel any time from your billing portal; the subscription ends at the close of the current billing period. License keys remain valid through that period. We don't pro-rate on cancel because the OSS core is enough for most users — the Team tier is a "support yourself by supporting us" relationship, not a hostage situation.
