Show HN: Tunlr – Expose local environments globally with self-hosted infra

Hello HN, we built Tunlr, a low-friction Cloudflare Tunnel alternative that can be self-hosted. It's a reverse-proxy server/client that tunnels HTTP traffic over standard HTTP1/2 without WebSockets or custom ports, and it plays nicely with enterprise firewalls.

Tunlr came about mostly because Cloudflare Tunnels were so awkward to use within CI/CD pipelines and dev setups, they don't support local file serving, and we wanted something we could host ourselves for local developer environments.

Tunlr clients can be configured to limit requests via HTTP header and IP address checks, and will eventually support having the Tunlr server act as an OIDC authentication portal. TCP proxying is also on the roadmap, but we don't really have a business case for it yet that justifies the work.

You can try out Tunlr client without signing up for anything--you'll get a valid certificate and hostname (via Tunlr Cloud, under tunlr.link) which you can use for testing webhooks, redirects, or anything else that requires public access:
