# About Canonical: https://motionspec.dev/about About MotionSpec — who builds it — MotionSpec MotionSpec ← motionspec.dev About ## Who builds MotionSpec. MotionSpec is built and maintained by Kevin Fröba through Fröba Sales Solutions UG (haftungsbeschränkt) , a company registered in Kronach, Germany. It is a small, deliberately focused operation: one maintainer, a public MIT core, and a stated scope on every page rather than broad claims. ## The person behind it Kevin Fröba is the founder and maintainer. The work concentrates on one narrow, under-served layer of the web stack — UI motion — and on the security engineering around operating it: an SSRF-guarded audit service, key-gated infrastructure, an SBOM, and a fuzz-tested core. The company details, including the commercial register entry (HRB) and VAT ID, are published in full on the MCP docs Pricing Impressum . ## What MotionSpec is MotionSpec checks and compiles UI animation in AI-generated web apps — it does not generate AI video. The core is MIT-licensed and public on npm : 40 reviewed motion primitives and 295 automated tests that compile reduced-motion-safe, performance-budgeted animation. The operated layer — the hosted checking service and catalog upkeep — is the commercial product. MotionSpec does not claim to make a site EAA- or WCAG-compliant; the honest scope is stated on every page. ## How to check what we claim The point of an open core is that you don't have to take any of this on faith: Read the source and the test suite on npm and GitHub — no key required. Run the free motion check on any URL; it's the same MIT engine the product uses. Follow the tool-independent method in How to verify web motion accessibility to check any site by hand.
