Fix it. Verify it. Build on it.
MotionSpec™ is verification technology you can run (MIT open core), rent (keyed hosted MCP), or embed in your platform (license) — each with its scope stated plainly. The free motion check and the keyless MCP tools stay free — no signup, nothing stored.
Platforms & OEM
For AI site-builders and codegen platforms shipping motion at scale.
- Proof Sprint: we benchmark 50–100 pages your platform generates — you keep the report and prototype either way
- Design Partner: hosted MCP with SLA, dedicated keys, roadmap voice, named engineering support
- OEM: annual embedded license, optional source escrow for the premium catalog
- Priced on measured value from the sprint — we don’t publish platform pricing
Details in the Design Partner Program
Hosted MCP — keyed
For teams whose agents should compile & audit, not just validate.
- Everything keyless (motion_catalog, motion_validate) — free forever
- Keyed tools: motion_compile, motion_audit, motion_stats
- Deterministic output — cache a spec once, reuse it for free
- Works in Claude Code, Cursor, and any MCP client — setup docs
- No SLA at this tier — that lives in the partner program
Keys are issued same-day by a human.
Open core — MIT
For developers who want to run the technology themselves.
- The compiler, all 40 verified primitives, and the MCP server — MIT on npm
- Keyless hosted tools (motion_catalog, motion_validate) — nothing submitted is stored
- The free motion check for any URL
- Read it, fork it, or bring your own diligence — the code is never the paywall
Setup in any MCP client: connector docs
What none of these plans claim
No MotionSpec plan makes your site “EAA-compliant”, “WCAG-compliant”, or “guaranteed accessible” — no tool can promise that, and we won’t. Every plan covers specific, machine-checkable motion criteria (WCAG 2.2.2, 2.3.3, and flashing checks in motion audit), stated per report with date and scope. Runtime JS/GSAP motion is flagged as not audited. If you need a full accessibility audit, hire a specialist consultancy — we’ll happily coexist with their findings.
Do you sell to platforms only?
Both, in different ways: engineering teams get keyed access to the hosted MCP, and platforms & OEMs license the technology itself — always scoped through a paid Proof Sprint first. The MIT core stays free for everyone.
Can I just use the MIT core for free?
Yes — the compiler, all 40 primitives, and the MCP server are MIT on npm. You’re paying for operated verification, hosted convenience, and dated reports — never for the code.
What happens to the free check and keyless MCP?
They stay free. They’re how you find out whether you have a problem; the plans are for when you want it fixed or enforced continuously.
