Cache everything
Turn slow, rate-limited APIs into instant responses.
Make any API faster, cheaper, and more reliable — instantly.
Direct API Request
Cached via CORSPROXY
Why developers choose CORSPROXY caching
Stop worrying about API performance. Let our global edge network handle the heavy lifting.
Bypass Rate Limits
Third-party APIs limiting your requests? Our cache serves repeated requests without hitting the origin, keeping you under limits.
Instant Response Times
Cached responses are served from the edge location nearest to your users. Sub-50ms response times, guaranteed.
Handle Traffic Spikes
Your viral moment won't crash the origin API. Our cache absorbs traffic spikes while maintaining consistent performance.
How it works
Add caching to any API in seconds. No configuration required.
Prepend the proxy URL
Just add https://corsproxy.io/?url= before your API URL.
fetch("https://api.example.com/data")
// After
fetch("https://corsproxy.io/?url=https://api.example.com/data")
First request caches the response
The first request fetches from the origin and stores the response in our global edge cache.
Subsequent requests are instant
All following requests are served directly from the edge — no origin hit, no latency, no rate limits.
