CORS Anywhere became everyone's go-to when they needed to bypass browser CORS restrictions. Here's how the alternatives compare in 2026.

CORS Anywhere's public demo is frequently rate-limited or blocked because it's open to everyone. ToolBit requires a JWT token, so your quota isn't shared with the entire internet.
ToolBit blocks requests to internal IPs (10.x, 192.168.x, 172.16-31.x), localhost, and .local domains. Public CORS proxies often have no such protections, making them risky to operate.
CORS Anywhere's README explicitly says it's a demo and not for production. ToolBit is a commercial service with uptime monitoring on our own infrastructure.
AllOrigins only supports GET requests. ToolBit and CORS Anywhere support GET, POST, PUT, PATCH, DELETE - covering the full API testing use case.
CORS Anywhere's public demo at herokuapp.com requires manually clicking a button to enable access, is frequently down, and is often throttled. It was never meant for anything beyond demos.
CORS Anywhere is an open-source project you're meant to host yourself. If you're willing to set up and maintain your own server, that's a valid path - but it requires infrastructure and maintenance.
The public demo server was never designed for production use. Heroku changed their free tier policy, and the demo is now manually throttled by the maintainer. You have to visit the demo URL and click a button to unlock access for a short period.
AllOrigins is a community-maintained open-source project. It's free to use the public instance, but there are no official rate limits or uptime guarantees. It only supports GET requests, which limits its usefulness for API testing.
A CORS proxy lets your browser-side JavaScript make requests to external APIs that don't include CORS headers. Instead of the browser hitting the API directly (which gets blocked), it hits the proxy, which forwards the request server-side and returns the response.
For development and testing, it's generally fine. For production, you should be careful - open proxies can read your request data including any API keys you pass. ToolBit's authenticated proxy reduces this risk compared to fully public proxies.
Not currently. The proxy is designed for JSON/text API requests. Binary file proxying is on the roadmap for Pro plans.
50 free proxy requests per day. Authenticated, SSRF-protected, reliable. No credit card needed.
