Simple, personal HTTP(S) tunnel service to share your work, test webhooks, or demo features without deployment.
Outprobe is currently under active development. I built this tool for my own use and want to understand how others might benefit from it before scaling up.
I'm granting early access on a case-by-case basis to gather detailed feedback and understand real-world use cases. If you're interested in trying it out, contact me at beta@outprobe.dev and tell me about your use case.
All tunnels use HTTPS with automatic Let's Encrypt certificates. Your data is encrypted in transit.
Same subdomain across reconnections based on your machine ID. No need to update webhooks every time.
Built with Go and Connect RPC for high performance. Minimal latency, maximum uptime.
No configuration needed. Just specify your port and go. Works out of the box.
Will be fully open source and self-hostable after release. Review the code, contribute, or run your own instance.
No registration, no login, no tracking. Install and use immediately.
# Expose local server on port 3000 outprobe 3000 Tunnel established https://489228f5.outprobe.dev → localhost:3000 Press Ctrl+C to stop
# Generate new random subdomain outprobe 3000 -U # Verbose mode with request logs outprobe 3000 -v # Custom local host outprobe 3000 --host 127.0.0.1
Outprobe creates a secure tunnel between your local server and our edge servers. When someone visits your subdomain, we proxy the request through the tunnel to your local machine and return the response.
Your subdomain is deterministically generated from your machine ID, so you'll get the same URL every time you connect. This makes it perfect for webhook development and API integrations that need stable endpoints.
