I've loved the way you're really trying to satisfy users' requests to make Corsfix an outstanding product. This is the aptitude I really like to see around me and my team.

I've tried a couple more proxy services but they didn't work as I was expecting, or at all. With that said I was quite surprised at how easy it was to use Corsfix and how well it's documented.

Frequently Asked Questions

What is this free CORS proxy about?

The free CORS proxy by Corsfix helps you solve CORS errors in your web app. It allows you to make requests to a target URL, and the proxy fetches the data on your behalf, returning it with the correct CORS headers.

Is Corsfix free to use?

Yes. You can use Corsfix for free within the free tier limits, with no signup required. When you need more, upgrade to a paid plan.

Does it work in production?

Yes. With the Corsfix SDK, the free tier works on your live website too, not just during development. Your site keeps working the moment you deploy.

Do I need to sign up?

No. Add the Corsfix SDK and it works without an account. Registering your domain in the dashboard raises the monthly data transfer from 10 MB to 100 MB.

Do I have to use the SDK?

The SDK is the recommended way to use Corsfix for free. While developing on localhost, you can also just add the proxy URL in front of your request, no setup needed.

Do you support open source projects?

Yes. Sponsored open source projects get unlimited requests for their public project website. It is subject to approval and for public repositories only. Apply here.

Is it secure to route my API requests through Corsfix?

When you route requests through Corsfix, we read the target URL to proxy the request and modify the response to include appropriate CORS headers. Any data processed is solely for providing our services and features.

What are the limits for the free tier?

The free tier includes unlimited requests at 60 requests per minute, 100 MB of monthly data transfer per registered domain (10 MB without registering), and 1 concurrent user at a time. Cached response and secrets variables are available on paid plans. When a limit is reached, the Corsfix SDK shows a small notice on your website so you know it is time to upgrade.
