In plain English

People who build websites can use Prufa to test a site the way a real visitor would, including signing up, logging in, and paying. Ordinary computer instructions check each result, and comments that are only opinions are labeled as advice, not proven facts. Teams pay because catching those problems by hand takes a long time, though anyone can paste a web address for a short free check with no account. People get reports and chat alerts, and other computer helpers can run the same checks. The AI does most of the testing and the billing, while Gregory Potemkin still checks quality, helps teams, and reviews strange results.

Overview

Prufa is an AI QA engineer for web products. An LLM-backed agent navigates your app like a real user — signup, login, checkout — and plain code verifies every result. Findings are machine-verified with evidence; LLM judgments are clearly labeled advisory. Humans get a dashboard, reports, and Slack alerts; AI agents get a CLI, versioned API, MCP server, and an agent skill. Free 60-second audit: paste a URL, no signup.

Operator: Gregory Potemkin. Category on TrustMRR: Developer Tools. Founded: 2025-08-27. Website: https://prufa.dev/
