Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
tdad
Test-driven regression guard for AI coding agents. After every code change, TDAD looks up impacted tests via a code-test dependency graph and runs only the affected tests before submitting a patch. It also enforces that every change includes a new regression test. Supports Python, JavaScript/TypeScript, Go, Java, Rust, and Dart projects. Evaluated on SWE-bench Verified, it reduced AI-introduced regressions by 72%.
Tada: automated QA for AI-written code
Your coding agent asks Tada to work through a feature in a real browser and gets back a verdict.
