Legit.Show — every launched service, tested

A directory of launched web apps, SaaS, AI tools, MCP servers and developer tools. Every listing carries an objective 7-Frame production-readiness benchmark — measured deterministically from the public surface, showing exactly what was observed. Never a black-box verdict.

What we measure — the 7 Frames

Each service is scored 0–100 on seven frames, from the public surface (URL · HTTP headers · real Lighthouse), so even closed-source SaaS is fully assessable:

Open-source repos additionally get a deeper code teardown (tests · CI · license · error tracking · MCP auth surface). No LLM in the scoring path — deterministic and reproducible.

Is a tool production-ready?

That's the question Legit.Show answers with evidence. Each service page leads with its overall score, the per-frame breakdown, and exactly what we observed — so "is this legit?" has a citable, reproducible answer instead of star ratings alone.
