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.

It's very easy to use other providers. See https://openrouter.ai/ which also let's you filter by where the provider is hosted and their data retention policy. - Source: Hacker News / 2 months ago
If you want to try it yourself: grab OpenCode, point it at OpenRouter, select GLM 5.2, and give it a real task instead of a benchmark. The z.ai docs have the rest of the details. - Source: dev.to / 3 months ago
Hosted, minimal ops. You want to be calling models in five minutes and you are fine paying a small fee for it. OpenRouter is the marketplace default — 400+ models, ~5.5% on credits. Vercel AI Gateway and Cloudflare AI Gateway go further and charge 0% markup, billing you at provider list price while adding routing and caching on top. - Source: dev.to / 3 months ago
