As answered by people managing Pinggy.io and CorsProxy.dev.
Pinggy.io's answer
No need to install any binary. One command creates a HTTP / TCP / TLS tunnel to localhost. Works in windows / mac / linux.
CorsProxy.dev's answer:
It's a managed CORS proxy that blocks requests to private IPs, loopback, and cloud metadata endpoints (SSRF protection) by default — most CORS proxies don't do this at all, hosted or self-hosted. The hosted API and the self-hosted binary run the same open-source Go core, so you can start on the free managed tier and move to self-hosting later without changing how you call it. It also runs a remote MCP server, so AI agents (Claude Code, Cursor) can call third-party APIs through your key without ever seeing the upstream secret.
CorsProxy.dev's answer:
Most free CORS proxies (corsproxy.io, allorigins, cors-anywhere) are unmanaged public relays with no auth, no logs, and no SSRF protection — fine for a demo, risky for production. CorsProxy.dev gives you per-key auth, rate limits, request logs, and a dashboard on a free tier, plus an open-source self-host path (MIT) if you'd rather not depend on a hosted service at all.
CorsProxy.dev's answer:
Go (self-hosted / open-source core), TypeScript on Cloudflare Workers (hosted SaaS), Cloudflare KV, D1, and Durable Objects for rate limiting.
CorsProxy.dev's answer:
Frontend and full-stack developers who need their browser app to call a third-party API that doesn't send CORS headers — indie hackers and small teams shipping fast without standing up a backend just to proxy one API call, plus developers wiring AI agents up to external APIs.
