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
tailtest
tailtest automatically generates and runs tests every time Claude Code edits a file. No commands, no configuration, no reminders needed. It hooks into Claude's file write event, detects your language and test runner automatically, generates production-like test scenarios for the code that was just written, and runs them immediately. If everything passes, it stays silent. If something breaks, you see it in the same session while the context is still fresh. Supports Python (pytest), TypeScript and JavaScript (vitest, jest), Go, Rust, Ruby, Java, and PHP. Works on new projects and existing codebases. On first run, a ramp-up scan queues your existing untested files for gradual background coverage.
