The Easiest Way to Test APIs Without Installing Software

DiyoVM Online API Tester is a professional developer tool that allows you to test HTTP requests (GET, POST, PUT, DELETE) without installing heavy software like Postman or Insomnia. Thanks to our cloud-based proxy system, you can send requests to any server without getting stuck with the browser's "CORS (Cross-Origin)" barrier.

Why Should I Use This Tool?

🚀 Built-in CORS Proxy: When sending requests directly from the browser, most APIs give a "CORS Error". Our tool forwards the request through a secure tunnel on our server, ensuring 100% success.
🛡️ Advanced Auth Support: Easily configure authentication methods like Bearer Token, Basic Auth, or Custom Headers.
💻 Code Snippet Generator: Instantly convert your request into cURL, PHP, Python, JavaScript (Fetch), or Go code and paste it into your project.
📥 cURL Import: Paste complex cURL commands copied from the terminal or documentation, and the tool will automatically fill in the forms.

Frequently Asked Questions

Can I test my API on localhost?

No. Since this tool runs cloud-based, it cannot access your "localhost". Your API needs to be on a public server or exposed via a tunnel service like Ngrok.

Are my API keys secure?

Yes. Your requests come to our server encrypted (HTTPS) and are immediately forwarded to the target API. No Header, Body, or Token data is saved to our database.

Which request methods are supported?

We support all methods in the standard REST architecture (GET, POST, PUT, DELETE, PATCH, OPTIONS, HEAD).
