Flowgen - One sentence in. A shipped, audited app out.

Flowgen is a suite of slash commands for Claude Code that runs one idea through five disciplines — design, code, security, test, debug — in six numbered phases. It doesn't just generate code — it attacks it. Phase 4 runs live DAST on your app in Docker: 40 attack primitives, 10 reasoned zero-day hypotheses, 13,600+ Nuclei security templates (~4,400 CVE). Then it hands you the evidence. Free Edition is $0 forever, no card. Full Edition is a one-time purchase. No subscription. No telemetry.

VistoFormat - robots.txt, rebuilt for AI readers

obots.txt told crawlers how to read the web. AI reads differently — it extracts and cites. Visto Format is an open spec for structuring content so LLMs can read it, plus a BYOK tool to measure if you're actually getting cited. Spec is free and open source.
