Pricing

The first check is free.Staying checked is what you pay for.

Every tier is the same loop: a real AI agent attempts your task in a real browser, and the evidence — screenshots, console errors, the agent's own reasoning — arrives at a private link. You pay when you want that loop running on its own.

Free

£0one real check

Watch a real agent try your site — and keep the evidence.

  • A real, state-of-the-art agent attempts the task you type, in a real browser
  • Every step captured: screenshots, console errors, the agent's own reasoning
  • One private report link you can forward — no account, no card

Pro

£49per month

Verification on every deploy — you hear about it only when the answer changes.

  • Your checks re-run on a schedule, or on every deploy through a simple hook
  • An alert when the answer materially changes — silence while everything still works
  • Different agents attempt the same task, so you see who gets stuck and where
  • A live badge for your site that links to the latest evidence
  • 200 checks included every month

Agency

£129per month

The same loop, run for the sites you manage.

  • Check your clients' sites as well as your own — 1,000 checks every month
  • White-label-ready reports your clients open without an account
  • Everything in Pro: re-runs on deploy, change alerts, and the multi-agent comparison

Prices are monthly. Checkout and billing run on Stripe; the free check never asks for a card.

Every check is a real agent in a real browser

No simulations, no static scans, no number you have to interpret. Each run ends one of three ways: the agent finished your task, the agent got stuck at a step we name, or our own run broke — and when it's our side that failed, the report says so plainly and never blames your site.

See what an agent does on your site first.
