Made some progress today on a CLI you can also talk to

Pretty happy with the UX of it even though it's no where near "done" 😅😅😅

I've tried CodeRemote, YoloCode, Omnara, Claudia, Conductor, Cursor Agents, Kisuke is taking forever to ship, Tonkotsu, Terragon Labs.

Nothing beats github.com/slopus/happy with Claude Code. Simple, #OpenSource, and free for the win 🥇

How does it work?

Start Happy CLI and you'll have a regular Claude Code session. But you can continue that same session from iOS, Android, or Web

Happy has three parts that work together:

CLI Program (happy)

└─

This runs on your computer. It starts Claude Code and watches what it does. Then it encrypts this information and sends it to a server.

Mobile App

└─

This runs on your phone. It gets the encrypted data from the server and shows you what Claude Code is doing. All the display code lives here.

Relay Server

└─

This connects your computer and phone. It passes encrypted messages between them. The server can't read your data. It just moves encrypted blobs around.
