Show HN: Sarab – Expose localhost to the internet using Cloudflare Tunnels

1 point

4 months ago

I built Sarab to make exposing local ports easier without needing paid services or complex config. It’s a single-binary CLI that automates Cloudflare Tunnels.

Key features:

- No Account Needed: Uses TryCloudflare to generate random public URLs instantly without login.

- Zero Config: Automates the cloudflared binary management, DNS records, and ingress rules.

- Auto-Cleanup: Automatically tears down tunnels and cleans up DNS records upon exit to prevent stale entries.

- Custom Domains: Supports authenticated mode using Cloudflare tokens if you need persistent URLs on your own domain.

It’s open source and written in .NET 10. Feedback welcome! [https://github.com/meedoomostafa/sarab]
