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
SearchFit SEO
Free AI-powered SEO toolkit — audit websites, plan content strategy, optimize pages, generate schema markup, cluster keywords, and track AI visibility. Works with any website or codebase.
unstack
Analyzes any website's technology stack from a single URL using only public signals. Runs a five-phase investigation (HTTP headers, HTML source, cookies, asset URL patterns, framework path probing) against 100+ detection signatures, then produces either a styled HTML report or a quick chat summary. Every technology identified is backed by specific evidence (the exact header, cookie format, or URL pattern that revealed it), not guesses. No API keys, no headless browser, no external dependencies.
