Cloudflare Tunnel (cloudflared) is an amazing tool — lightweight, secure, fast, and perfect for exposing local services without opening ports or managing firewalls.

But many users run into the same issue:

Tunnels are powerful, but the CLI/YAML workflow is not always convenient for quick, ad-hoc usage.

If you want to open an RDP session, temporarily expose an SSH service, or forward a TCP port for a teammate, you often need to:

write or edit a YAML file

remember a set of CLI flags

manage multiple tunnel processes manually

So I decided to explore a simple idea:

What if `cloudflared` had a tiny, friendly desktop UI?

Something minimal. Cross-platform. One-click.

A small helper tool — not a replacement for the CLI — but a shortcut for common tunneling tasks.

I built a prototype:

https://github.com/mlanies/desktop-argo-tunnel

Dashboard

What the app does

The UI focuses on the most common use cases:

Launch an RDP tunnel

Launch an SSH tunnel

Launch a TCP tunnel

View connection parameters

Start/stop tunnels with a single button

No YAML.

No terminal commands.

Just “Start tunnel”, “Stop tunnel”.

Internally it still uses cloudflared — the app simply generates the right arguments and manages the process lifecycle.

Why build this?

I noticed several recurring pain points among developers and sysadmins:

✔ Quick access should be easy

For one-time tunnels, writing YAML feels unnecessary.

✔ Not everyone on a team is comfortable with CLI

A UI helps junior engineers, support staff, or remote colleagues.

✔ Great for demos, remote assistance, and small internal setups

Some people just need an SSH or RDP tunnel right now — not a Zero Trust enrollment or a full access policy flow.

✔ It makes Cloudflare Tunnel more accessible

A friendly UI lowers the entry barrier.

Tech details

The prototype is built with:

Go — for calling and managing the cloudflared binary

Electron — for a clean, simple interface

Cross-platform intent (Windows/macOS; Linux coming soon)

The project is experimental, but functional.

Looking for feedback

I would love to hear your thoughts:

Should Cloudflare consider an official desktop UI for tunnels?

What features should such a tool include?

Would your workflow benefit from one-click RDP/SSH/TCP tunneling?

Any UX suggestions for the app?

I’m actively collecting feedback to shape the next iteration.
