As answered by people managing jello and Parsistent.
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.

Yep, you can create a filter in jq to do that. Alternatively, if you prefer Python syntax you could try jello, which works like jq but is really Python under the hood. (I am also the author of jello). Source: over 3 years ago
