Hi Product Hunt! Every time we needed to test a scraper, an HTTP client, or lately an AI agent, we'd either end up scraping someone else's real website or hand-rolling a one-off test page and throwing it away afterward. So we built the thing we kept wishing already existed: a free sandbox with predictable structure that's safe to point any tool at. What's in it today: Web scraping: an ecommerce catalog, pagination patterns, JS-rendered content, forms, login walls, plus canonical tags, meta robots directives, hreflang, and URL normalization edge cases HTTP & networking: an httpbin-style set of status codes, redirects, auth, caching, streaming, and rate limiting Mock Data APIs: deterministic fake REST endpoints (Users, Posts, Albums, Todos) to prototype against Generators: on-demand fake users, test credit cards, dummy files, placeholder images AI & LLM testing: a prompt-injection test page, a RAG retrieval corpus with a documented answer key, and PDFs built specifically to stress-test extraction (tables, multi-column layouts, repeated headers/footers) Every page does the same thing on every request unless its own description says otherwise, so it's safe to write real automated tests against. No signup, no rate limits except the one page built to demonstrate rate limiting, and it's open source: github.com/geekflare/testingurl Would love to hear what you end up testing against it, and what's missing. Thanks for checking it out!
