As answered by people managing Parsistent and MockServer.
Parsistent's answer
Built by a solo developer who needed a single place to test proxies, inspect HTTP responses, and debug CSS selectors while building scrapers. All existing tools required accounts or didn't support proxies natively.
Parsistent's answer
Built-in proxies (HTTP, SOCKS4, SOCKS5) are provided for free — no need to bring your own. The HTTP Request Tester automatically detects anti-bot systems (Cloudflare, DataDome, PerimeterX) and traces redirect chains. All tools work without signup.
Parsistent's answer
Unlike Reqbin or HTTPie, Parsistent provides free built-in proxies so you can test requests from different IPs instantly. It also detects anti-bot protection automatically and combines 8+ parsing tools in one place — no account needed
Parsistent's answer
Web developers and data engineers who build scrapers, test APIs, or debug HTTP requests. Also useful for QA engineers testing geo-restricted content and developers learning CSS selectors or XPath.
Parsistent's answer
Next.js 16, TypeScript, Tailwind CSS, Vercel (hosting). Server-side proxy support via https-proxy-agent and socks-proxy-agent.

I've just found out MockServer and it looks awesome 🤩 so I wanted to check it out repeating the steps of my previous demo WireMock Testing which (as you can expect) uses WireMock, another fantastic tool to mock APIs. - Source: dev.to / over 4 years ago
