IP Test

🌐 Minimal HTTP server that echoes your IP and request headers as HTML or JSON.

Built with Elysia on Bun.

Usage

Send a request to /:

• Browsers (Accept: text/html or */*) get an HTML page listing the detected IP and all request headers.
• Anything requesting Accept: application/json gets a JSON body: { "ip": "...", "headers": { ... } }.

curl -H "Accept: application/json" http://localhost:3000/

Development
