A Postman Alternative in Your Browser

This web-based API tester lets you send HTTP requests and inspect responses without installing the Postman desktop app. Choose any method — GET, POST, PUT, PATCH, DELETE — add custom headers, query parameters and a request body, then send the request and view the formatted response, status code and timing right in your browser.

It is ideal for quickly checking a REST endpoint, debugging an integration or testing an API while you build. Nothing is installed and your requests run from your own browser session.

Frequently Asked Questions

Which HTTP methods are supported?

All common methods are supported, including GET, POST, PUT, PATCH and DELETE, so you can test full CRUD APIs.

Can I send custom headers and a JSON body?

Yes. You can add any number of custom headers and include a raw request body such as JSON, which is useful for authenticated requests and POST payloads.

Why am I getting a CORS error?

Browsers enforce CORS for cross-origin requests. If the target API does not send the right CORS headers, the browser will block the response. This is a browser security feature, not a fault of the tool.

Do I need to install anything?

No. Unlike the Postman desktop app, this tool runs entirely in your browser with nothing to download.

Is it free?

Yes, the API tester is completely free and needs no account.
