Introducing our online CORS Tester

I’m excited to introduce CORS Tester, a handy tool built to help you quickly test whether any URL for CORS support. If you’ve ever struggled with CORS, then this tool is for you.

Why CORS Tester?

Setting up CORS can sometimes be trickier than expected, or you might be working with a third-party API and unsure whether they support CORS. With CORS Tester, you can find out in seconds.

How It Works

CORS Tester simulates how CORS behaves in your browser. Here’s what you can do with it:

• Test API CORS Support: Simply enter the target URL and specify the origin that’s sending the request.
• Customize Your Request: Modify the request method, headers, and body to match your testing needs.
• Simulate Preflight Requests: Some requests require a preflight check before sending the actual request. Our CORS Tester automatically handles this for you.

Once you run your test, CORS Tester will tell you if your API call would succeed via CORS. If it doesn’t, you’ll get clear information into what went wrong and which aspect needs fixing.

When to Use CORS Tester

Whether you’re developing a new API or need to check if a third-party URL supports CORS, this tool is a great addition to your developer toolkit.
