Tunneling OpenClaw Skill - ClawHub
Do you want your AI agent to automate Tunneling workflows? This free skill from ClawHub helps with web & frontend development tasks without building custom tools from scratch.
What this skill does
Create free SSH tunnels to expose local ports to the internet using tinyfi.sh. Use when you need to share a locally running app, test webhooks, demo a prototype, or get a public HTTPS URL for any local service — no signup or authentication required.
Install

TinyFish Tunneling Service (tinyfi.sh)
Creates instant public HTTPS URLs for locally running apps via SSH tunneling. Free, no account, no installation beyond SSH.
Pre-flight Check (REQUIRED)
Verify SSH is available (it almost always is):
which ssh && echo "SSH available" || echo "SSH not found — install OpenSSH first"
Quick Start
Expose a local port to the internet:
ssh -o StrictHostKeyChecking=accept-new -R 80:localhost:<PORT> tinyfi.sh
Replace <PORT> with the port your app is running on. The command will print a public https://<random>.tinyfi.sh URL.
Custom Subdomain
Request a specific subdomain instead of a random one:
ssh -o StrictHostKeyChecking=accept-new -R myname:80:localhost:<PORT> tinyfi.sh
This gives you https://myname.tinyfi.sh.
Keep-Alive (Stable Connections)
For long-running tunnels, add a keep-alive interval to prevent disconnection:
ssh -o StrictHostKeyChecking=accept-new -o ServerAliveInterval=60 -R 80:localhost:<PORT> tinyfi.sh
Usage Guidelines
When starting a tunnel for the user:
- Ask which port to expose if not already specified
- Run the SSH command in the background so the agent can continue working
- Report the public URL back to the user once the tunnel is established
- The tunnel stays open as long as the SSH connection is alive
