A free, 100% browser-based cURL tool that runs entirely in your client

Hi everyone,

I built curl.codewithneo.com because I was tired of switching back and forth between my terminal and the browser just to test quick API requests, format payloads, or debug headers.

While there are plenty of web-based HTTP clients out there, a lot of them send your data through their own backend servers. As a developer/security researcher, sending API keys, bearer tokens, or sensitive payloads through a third-party server always felt like a massive security risk.

So I built a completely client-side alternative.

Key Features
100% Browser-Based: All requests are executed directly from your browser. Your sensitive API keys, tokens, and endpoints never touch an external backend server.

Completely Free: No paywalls, no "premium tiers" for basic HTTP methods, and no sign-ups required.

Clean UI: Fast, lightweight, and built to let you drop in a cURL command or construct a request in seconds.

Why use this over a local terminal?
Sometimes you just want a clean visual interface to inspect response headers, pretty-print massive JSON payloads, or quickly tweak a request without messing up your terminal history.

I’d love to get your feedback on it. What features should I add next? If you encounter any CORS issues or have ideas for improvements, let me know!
