This saved us days of work. Dropped it into our pipeline and had UCP endpoint validation running in about 20 minutes. Documentation is accurate.

The best developer tool in this category. TypeScript types are correct and complete. Error messages actually tell you what went wrong.

Solid tool. The test suite coverage is excellent. I found one edge case in the payment token validation that the maintainers fixed within 48 hours.

Integrated in an afternoon. The discovery endpoint just worked. The CLI flags are well-designed — composable, no magic defaults.

Good tool for UCP conformance testing. Runs fast and the output is easy to parse in CI. Would like a JSON output mode — currently only text.
