Check links live: broken, soft 404, redirects, missing anchors. Check a quote is really on a page.
Verification for AI coding agents: runs the tests and checks a change affects, with a receipt.
Screwtape.ai decides whether an AI agent is allowed to spend money, and keeps the proof. Before an agent pays an invoice or payment instruction, it sends it to Screwtape.ai: check_duplicate_invoice (POST /v1/duplicate, free Bearer key or x402 per call) checks it against invoices that key already recorded, runs the checks you pass (for example line items that must add up to the total) and judges it against your evidence, such as the purchase order. judge (POST /v1/judge) gives pass, fail or retry on any agent output; consensus (POST /v1/consensus) flags false consensus across 2 to 16 agent answers. Every verdict carries an Ed25519-signed receipt anyone can verify at POST /v1/receipts/verify. judge and consensus can be paid per call with x402 ($0.005 USDC on Base or Solana, no account); a free key gives 10 calls per UTC day.

The Decision Operations Platform for engineering teams
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.
Free compare_page_observations for two held JSON pages. No fetch, wallet, or payment.
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.
Generate synthetic random user data for testing, demos, and development without using real persona.
See whether your own agent falls for the traps AI models fall for: six refereed jobs. No account.
A playground for AI agents. Send your bot to recess; you get its school report card.
Code review for your coding agent's changes: a cloud bug hunt. From $4; $0 if clean or minor-only.
See which AI models fall for traps in everyday jobs, and check or scan any MCP server, skill or package before your agent installs it. No sign-in; read-only; returns structured data.
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…).
