Fix it. Document it. Build on it.
MotionSpec™ is motion evidence technology you can run (MIT open core), rent (keyed hosted MCP), or embed (platform / OEM license) — scope stated plainly on every plan. Start free: the free motion check and the keyless MCP tools cost nothing — no signup, nothing stored. Self-serve starts at $29 when you want proof or power.
MotionSpec checks and compiles UI animation in AI-generated web apps — it does not generate AI video.
Self-serve
Fixed price. All three tiers check out instantly. Prices in USD; your local currency is shown at checkout. Checkout asks for the company name you are buying for — the invoice needs it. We build MotionSpec for teams and businesses; if you buy as a consumer, your statutory rights apply unchanged (see the AGB).
Two promises in writing — both narrower than a compliance guarantee, because that is the only honest shape one can take.
Motion Report, $29: refundable within 14 days, no questions asked — on top of your statutory rights. Re-checks stay free after you ship fixes.
Agency, $249/month: if the first full pass across your ten domains surfaces nothing nameable, you do not pay — first month refunded, keys stay live for thirty days. We can promise that because only 6 of the 196 AI-built pages we measured on 16 July 2026 came back clean on these checks.
What neither promises: that your site is compliant. No tool can honestly promise that, and we do not — read the exact scope and the fine print.
Agency
Most agencies start here
For agencies and teams that run keyed checks across client domains, not just one.
$24.90 per site per month.
- The same keyed tools — motion_compile, motion_audit, motion_stats — across several keys, one bill
- Ship client work with a dated audit history per domain — re-runs stay reproducible
- Deterministic output — cache a spec once and reuse it free, in any MCP client
- Catch regressions without looking: weekly re-scans of your domain
- Diff alerts the moment a deploy makes motion accessibility worse
- A live scan badge, refreshed by the latest scan
- Re-scans run the same checks as the Motion Report — same candidates, same WCAG mapping
- No SLA at this tier — that lives in the partner program
Ten client domains, each with a dated report you put your own logo on. Agencies put that on the client invoice as its own line item.
Finds nothing nameable? First month back
If the first full pass across your ten domains surfaces nothing nameable, you do not pay — first month refunded, keys stay live for thirty days. The exact wording.

Ten domain slots on one key, managed from your account page — add and remove them yourself. One developer, one domain? The Dev Key above is the cheaper fit. Need more than ten, or an SLA? Ask about the partner program.
Dev Key
For a single developer who wants agents that compile and audit, not just validate.
- Your agents do the work: keyed MCP + API access to motion_compile, motion_audit, motion_stats
- No queueing behind anyone — a dedicated rate limit of 60 requests / 10 s on your key
- Ship client work on it: commercial use for your own projects; embedding or reselling needs a partner license
- Show your work with /certify signing for MotionSpec spec documents
Cancel any time, from your own page
Your key is shown once on the page right after checkout, and you can rotate it any time from your account page. Cancel from the same page — it takes effect at the end of the billing period. The free keyless MCP stays free either way.
Motion Report
For a freelancer or site owner who needs one URL checked and a plan to fix it.
- See one before you buy — the full example report, a real scan of one of our own pages
- More than the free check shows — a full audit of one URL
- Fix it without guesswork — every candidate cited to WCAG 2.2.2 / 2.3.3 with a copy-paste snippet
- See how you compare — where your score sits among 196 AI-built pages
- In your browser right after checkout — printable as a PDF, and emailed too once our sending path is switched on; refundable within 14 days, no questions
Refundable within 14 days
Fourteen days, no questions asked — on top of your statutory rights. Re-checks stay free after you ship fixes. What the refund covers.
An engineering report, not legal compliance evidence — we detect; we never promise compliance.
Business & platform
Scoped per engagement and quoted, not self-serve. Prices excl. VAT.
Platforms & OEM
For AI site-builders and codegen platforms that ship generated motion at scale.
- Proof Sprint: we benchmark 50–100 pages your platform generates — report and prototype are yours either way
- Design Partner: hosted MCP with an SLA, dedicated keys, roadmap voice and named engineering support
- OEM: annual embedded license; continuity covered by the public MIT core on npm
- You pay against measured value from the sprint — we publish no platform pricing
Scope and stages are laid out in the Design Partner Program.
Open core — MIT
For developers who would rather run the evidence stack on their own machines.
- Run it all yourself: the compiler, all 40 reviewed primitives and the MCP server, MIT on npm
- Try it without an account — keyless motion_catalog and motion_validate store nothing you submit
- Check any URL for free with the free motion check
- Read it, fork it or bring your own diligence — the code is never the paywall
No key, no signup: set it up in any MCP client with the connector docs.
What none of these plans claim
No MotionSpec plan makes your site “ADA-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 audit.
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 evidence, 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.
