AnalyticsProof watches your website and Android app tracking so you're not the last to know it broke. Free: A consent scan. Does your site track visitors before consent or after they opt out? Paid: Record checkout or sign-up once. We replay it every day and email you when a GA4 or dataLayer event or parameter goes missing or something broke. Ask your agent: "Check checkout on example.com every day" or "Add an AnalyticsProof check to our GitHub pull requests."
Test healthcare AI agents' medication claims against cited FDA label text. Not for clinical use.
Verify before the agent pays. Screwtape is an independent check on agent work before a payment goes out: invoices, duplicate invoices and reconciliation, with a signed receipt for your auditor. It is independent of your agent's own model and vendor, with no stake in your agent passing. - judge: pass, fail or retry verdict on one agent output, with a score, reasons and a next_step. Optional deterministic checks: required fields, types, formats, sums, regex. - check_duplicate_invoice (/v1/duplicate): opt-in duplicate-invoice check using keyed fingerprints. - consensus: scores agreement across 2 to 16 agent answers and flags false consensus. - Advisory mode: recommends approve, review or return; a person decides. - Receipts: Ed25519-signed. The receipt proves what was checked, when, and the verdict. Verify via POST /v1/receipts/verify or offline; export via GET /v1/receipts/export. - Judged content isn't stored unless you opt in. Free key: 100 calls/day. Or $0.005 USDC per call via x402 on Base or Solana, no key needed.

Free AI visibility check: can AI crawlers read a site, and do ChatGPT, Gemini, Perplexity cite it?
UI Verify is visual regression testing built for coding agents. Connect the MCP server and your agent (Claude Code, Cursor, Codex) pulls a pull request's UI changes into the conversation, views each visual diff, reads the AI judge's verdict of regression vs intended change, and accepts the intended baselines - all over MCP.
HefestoAI checks AI-generated code before you ship it.
The beta program platform for hardware and IoT teams, who run structured betas with their own testers. Connect your AI assistant to build tasks and steps, screen applicants, triage tickets, read results and track tester progress. Actions that reach testers return a preview first and take effect only after confirmation. Sign in with OAuth, with read-only or read and write access. Stomio does not recruit testers.
Your AI designs live on the UX Pilot canvas or runs its design agent: reviews, React, video, media
Web animation accessibility MCP: GSAP, static CSS checks, prefers-reduced-motion, WCAG 2.2.2/2.3.3.
Your agent verifies its change before commit; PR review that knows what depends on your change.
Design quality gate for AI-generated UI: score any URL on 45 deterministic checks, A–F grade.
Generate synthetic random user data for testing, demos, and development without using real persona.
AI QA for coding agents. TestOptim explores your web app, generates end-to-end tests and reports bugs with severity. Over MCP, Claude Code, Cursor or Copilot can start a test run on just the pages they changed, poll the result, and read the issues it found. Authenticate with a TestOptim API key as a Bearer token.
EU cookie-consent & tracker audit, run like a real first-time visitor (EU proxies). Free quick check, no account. Finds trackers and tracking cookies before consent, missing first-layer Reject, what still fires after Reject, Google Consent Mode v2 state per signal, plus Google Fonts/YouTube/Maps/reCAPTCHA. Every finding comes with the exact request as evidence and a concrete fix, in 13 languages. Weekly monitoring, white-label PDF for agencies, private share links. Works with any CMP (Cookiebot, Usercentrics, Complianz, CookieYes, Borlabs…).
Check public web pages for common WCAG 2.2 accessibility issues from your MCP client. The free scan_url tool needs no account and returns a score, severity breakdown, WCAG references, affected elements and fix guidance. Automated checks do not establish conformance; manual review is still required. Optional authenticated tools support monitoring your own sites. Documentation: https://allyproof.com/docs/mcp
The Decision Operations Platform for engineering teams
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
Open a React Native app in a simulated phone: read the screen, tap, type, set device state.
Check a landing page on a real phone and desktop, get the fixes, re-check after you publish.
