ApiTab nga Apon

ApiTab is a lightweight, local-first API testing tool that opens instantly in your browser — a fast, minimal alternative to Postman.

No account. No login. No cloud sync. Everything you build stays on your device.


Heavier API tools take time to load, push you toward an account, and sync your data to their servers. ApiTab skips all of that. Open it, build a request, hit send — that's it.


Request Builder
- Full method support: GET, POST, PUT, PATCH, DELETE, OPTIONS, HEAD
- Query params that stay in sync with the URL bar
- Dynamic headers with autocomplete suggestions
- Auth support: No Auth, Bearer Token, Basic Auth, API Key (header or query)
- Body types: JSON (with beautify + live validation), Raw, Form URL Encoded, Form Data

Response Viewer
- Status code, response time, and response size at a glance
- Pretty or raw body view with JSON syntax highlighting
- Full response headers table
- One-click code snippet generation: cURL, Fetch, Axios, PHP cURL, Laravel HTTP, Python Requests

Collections & History
- Organize requests into collections — create, rename, duplicate, delete, search
- Automatic request history, with easy reopen or clear

Environments
- Set up Development / Staging / Production environments
- Use {{variables}} anywhere in your requests — resolved automatically before sending

Import & Export
- Paste a curl command directly into the URL bar to auto-populate a request
- Export/import your entire workspace as a JSON backup

Built for speed
- Dark mode
- Keyboard shortcuts for sending, saving, and copying requests as cURL
- Runs requests from a background service worker — no CORS headaches, accurate timing, full response headers


ApiTab stores everything locally in your browser. There's no backend server, no account system, and no tracking. Requests you send go directly from your browser to the API you're testing — we're not in the middle.


Developers, QA engineers, and anyone who needs to quickly test an API without opening a heavyweight desktop app or creating yet another account.
