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 CORS proxy?
CORS proxy by Corsfix is a service for solving CORS errors. When you make request to our proxy with your target URL, we fetch the data on your behalf and return it back to you without CORS errors.
Your website can then access the resource without any issues, as the proxy returns the data along with the necessary CORS headers.
Is the CORS proxy safe to use?
Yes, any data passed through our proxy is processed securely and used solely to provide our services. You can find our commitment to privacy in our privacy policy.
To safely use a CORS proxy, choose a service you trust, one that handles data responsibly. Rest easy knowing that we take your privacy and security seriously.
How does the CORS proxy work?
A CORS proxy acts as an intermediary between your application and the target server. When you make a request to the proxy with your target URL, the proxy fetches the resource and adds the necessary CORS headers to the response, allowing your browser to access the data without CORS errors.
Why do CORS errors occur and how can I fix it?
CORS errors occur when a web application tries to access resources from a different origin and the target server does not allow it via CORS headers. You can get around these restrictions by using a CORS proxy, which adds the required headers to the response so your browser can access the resource.
Do I need to use CORS proxy?
If you're building a web application that needs to access resources from different origins and you're running into CORS errors, then yes, Corsfix CORS proxy can help you get around the errors.
How do I use the CORS proxy?
Load the Corsfix SDK with a script tag (
<script src="https://unpkg.com/corsfix"></script>) or install it with npm install corsfix, then replace fetch with corsfix.fetch. The proxy will fetch the resource on your behalf and return it to you with no CORS errors. You can also call the proxy directly by adding https://proxy.corsfix.com/? before your target URL. See the SDK documentation for details.Which data types does the CORS proxy support?
Any types of data are supported, JSON, HTML, images, video, etc.
