API Tester
Send HTTP requests, inspect responses, and generate curl commands.
Headers
Generated curl
curl -X GET "https://jsonplaceholder.typicode.com/posts/1" \ -H "Accept: application/json"
Response
Send a request to see the response. Note: the browser blocks cross-origin requests unless the server sends CORS headers — this tool runs fully client-side.

JSON Formatter
Format, validate, minify, and prettify JSON data instantly.
JWT Decoder
Decode and inspect JWT tokens: header, payload, signature, expiration.
Base64 Encoder/Decoder
Encode text or files to Base64 and decode back. UTF-8 safe.
Regex Tester
Test regular expressions in real-time with match highlighting and groups.
Send HTTP requests to any CORS-enabled endpoint and inspect the full response: status, headers, body, timing, and size. Build requests with custom headers and JSON bodies, then export them as curl commands.
