Horizon

Sign-in and OAuth

Test OAuth and social sign-in on localhost with a stable HTTPS redirect URL from Horizon, for Google, Apple, Auth0, WorkOS, Firebase and more.

Give your sign-in provider an HTTPS redirect URL that points at your laptop, and keep it the same across restarts.

Many providers won't redirect to http://localhost. Some want HTTPS, and some reject localhost outright. A Horizon tunnel with a reserved subdomain gives you https://my-app.hrzn.run, which you register once. Start with Test OAuth redirect URLs locally for how it fits together, then pick your provider.
