A precision instrument, not a suite.

CrawlSpec turns site crawls into implementation-ready specs. Built for teams and agents that act on evidence, not adjectives.

Why crawlspec.dev

The name states the mechanism directly: crawl a site, output a spec. Not a dashboard of scores, an implementation-ready document a developer or an agent can act on without re-research. The CrawlSpecBot user agent and the calibrated-dial mark carry the same idea forward.
