Free API Testing Tool — No Signup | Send Web Request
Test any API in your browser—no signup or install. Just send.
Send Web Request is a free API testing tool that runs in your browser. No downloads, no signup required for the core tool, no credit card. Test any REST or SOAP API with custom headers, authentication, and request bodies. When you don't use an account, your request data doesn't leave your device. Optional Cloud Sync requires an account and subscription.
Features
• All HTTP methods: GET, POST, PUT, PATCH, DELETE, OPTIONS. • Custom headers: Authorization, Content-Type, Accept, and any header you need. • Query parameters and request bodies: JSON, XML, or raw. • Proxy mode for CORS-blocked APIs—test any endpoint. • Response viewer: status code, headers, and body with syntax highlighting. • Shareable URLs: copy a link to your request and share it.
Who this is for
Developers who need to test APIs quickly without installing software. QA engineers checking endpoints. Anyone on a restricted machine where Postman or curl aren't an option. Teams that want a zero-setup, privacy-first REST client online.
Send Web Request vs Postman
Postman is full-featured but requires installation and often an account. Send Web Request runs in the browser: no install, no signup, no workspace setup. You get the core of API testing—send a request, see the response—without the overhead. Use it for quick tests, demos, or when you need a free API testing tool that works in seconds.
Privacy and security
When you use the tool without an account, your requests and responses stay in your browser. We don't log your URLs, headers, or bodies. For direct requests, nothing goes through our servers. Proxy mode is used only when CORS blocks the request—we don't store or inspect your data. If you use Cloud Sync (saved requests), that data is stored on our servers for your account. For sensitive APIs and API keys, that matters.
Quick example
Enter a URL and click Send. Example:
GET https://api.github.com/zenIs Send Web Request really free?
The core API testing tool is free to use with no account, no trial, and no credit card. No feature limits for sending requests and viewing responses. Optional features—Cloud Sync (save requests to the cloud) and permanent webhook receiver URLs—require an account and a paid subscription.
