What is Mini Postman (API Tester)?
Mini Postman is a browser-based API testing tool for developers who need to quickly test REST APIs without installing desktop apps. Send GET, POST, PUT, PATCH, and DELETE requests with custom headers, query parameters, request bodies, and authentication — all from your browser. It works entirely client-side through a CORS proxy, so your data stays private and you can test APIs from any device.
How to use
1. Select an HTTP method (GET, POST, PUT, PATCH, DELETE) and enter your API URL. 2. Add query parameters, headers, request body, or authentication as needed. 3. Click Send (or press Ctrl+Enter) to execute the request. 4. View the response in Pretty (formatted JSON), Raw, or Headers tabs. 5. Use Import cURL to paste a cURL command from your terminal. 6. Use Generate Code to export your request as JavaScript, Python, PHP, or other languages.
Features
- HTTP Methods — GET, POST, PUT, PATCH, DELETE with color-coded badges.
- Request Builder — Headers, query parameters, JSON/raw/form body editors.
- Authentication — Bearer Token and Basic Auth support.
- cURL Import/Export — Paste cURL commands or copy requests as cURL.
- Code Generation — Export to JavaScript (fetch/axios), Python, PHP, Java, and cURL.
- Environments — Create variable sets (e.g., dev/staging/prod) with {{variable}} interpolation.
- Request History — Auto-saved with search, filter, pin, and reload.
- Shareable Links — Encode requests in URL-safe links (sensitive data excluded).
- Security Scanner — Real-time warnings for exposed tokens, credentials, or sensitive data.
- Request Templates — Pre-built templates for common API patterns.
- Keyboard Shortcuts — Full keyboard navigation for power users.
- Stateless Mode — Disable history/storage for sensitive work.
- 100% Client-Side — Your data never leaves the browser.
Technical Details
Edge Cases & Tricky Inputs
- •CORS restrictions may block requests to APIs that don't allow browser-origin requests.
- •File uploads in multipart/form-data are supported for POST/PUT requests.
- •Self-signed HTTPS certificates will cause browser security warnings.
Performance & Processing
- •Request timing includes DNS lookup, TCP handshake, and response transfer — displayed in the response panel.
- •Response bodies up to 10 MB are rendered; larger responses are truncated with a download option.
Developer Notes
- •Supports GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS methods.
- •Request history is saved in localStorage for quick replay of recent API calls.
- •Environment variables can be defined and referenced in URLs and headers using {{variable}} syntax.
Known Limitations
- •WebSocket and GraphQL subscriptions are not supported — REST/HTTP only.
- •Request chaining and automated testing sequences are not available.
- •Cookie management is limited to what the browser allows for cross-origin requests.
