Batch analysis and stack comparison beats BuiltWith's $295/mo starting price.
Combines Wappalyzer fingerprints with DNS CNAME, TLS issuer checks and header matching to triangulate tech stacks — a practical, non-flashy way to catch what single-source scrapers miss. Batch analysis, compare endpoints, CPE IDs for NVD mapping and 24h smart caching make it genuinely useful for audits and competitor research; it's not reinventing the space, but it adds meaningful, usable layers that established tools often omit.
Yet another stack analyzer competing with Wappalyzer and BuiltWith.
Wappalyzer detection + DNS + SSL in one cached API, but is mostly orchestration of existing tools.
Cross-repo health dashboard for multi-stack teams, but solves a niche workflow pain.
Railway and Render already do this with larger ecosystems and proven reliability.
