GulYour whole local stack on one public URL.

A self-hosted tunnel that puts your entire multi-service dev setup on one HTTPS URL.

One tunnel for your whole stack

The auto-router translator rewrites cross-service local URLs into gul routes on the fly, so your whole multi-service setup runs through one URL. No other local tunnel does this.

CORS just works

Bidirectional origin translation on Origin, Referer, and Access-Control-Allow-Origin, so cross-service browser calls are not blocked.

OIDC

Add your gul URL as a callback in your provider and log in through the tunnel. A provider on localhost needs nothing.

Self-hosted

You run the server, own the domain, and keep the data. No third party, no database.

Secured control plane

Only you can open tunnels, guarded by a browser OIDC login (Authorization Code + PKCE). Visitors stay anonymous.

One small binary

A self-contained CLI for 6 targets (Windows, Linux, macOS on x64 and arm64), one-line install.
