cors-proxy

cors-proxy

Reverse proxy to bypass CORS, used by spicetify at cors-proxy.spicetify.app. A Hono app on Cloudflare Workers.

Call it as cors-proxy.spicetify.app/<target-url> — the path after / is the target (keep it unencoded), e.g. cors-proxy.spicetify.app/https://github.com/owner/repo/releases/....

Features

• Bypasses CORS for the Spotify client (origin restricted to xpui.app.spotify.com).
• Rewrites protected request headers: send X-Cookie / X-Referer / X-Origin / X-User-Agent / X-X-Real-Ip, they're mapped to the real header upstream.
• Surfaces the (browser-blocked) upstream Set-Cookie as X-Set-Cookie and the final URL as X-Final-Destination.
• Per-request cookie jar (fetch-cookie) so cookies carry across redirects.
