AI Analysis

●●SolidShip ItNiche Gem

Ngrok alternative on Cloudflare Workers, but signup-free determinism is the only real edge.

Strengths
  • Consistent subdomains per port/client—actually useful for repeated testing flows.
  • No signup required; instant HTTPS tunnels reduce friction vs. Ngrok's auth wall.
  • Self-hostable via Cloudflare Workers lowers operational cost vs. centralized competitors.
Weaknesses
  • Feature parity gap: no auth, IP restrictions, or replay tools that Ngrok/Localtunnel offer.
  • Cloudflare dependency creates lock-in; if you self-host, you still need Workers setup.
Target Audience

Frontend developers, mobile testers, anyone needing secure local tunnels

Post Description

I'm building prod.bd, a lightweight open-source tunnel for exposing localhost services to the internet.

I originally made it because I often need to test frontend apps on real mobile devices during development. While tools like Ngrok and Tailscale Funnel work well, I wanted build something on my own.

You install it with a single command and then just run:

`prod 3000 8080`

It also has docker container too if you don't want to run untrusted binary.

It instantly gives you two HTTPS subdomain URLs that are publicly accessible. Subdomains are consistent for each port. It provides a simple stats dashboard to inspect url, headers and payload.

Under the hood, it uses Cloudflare's Workers, Durable Objects and D1. You can deploy your own version if you want.

I have used Kiro and Antigravity to build it. I wanted to experiment with AI tools while building something useful. On a side note, I am experimenting with plugin system to add new features while keeping core tunnel simple. Without AI tools, I would never try plugin system.

Would love feedback, suggestions, or ideas for improvement.
