About

Happy, also known as Happy Coder, is a free, open source mobile and web client that lets users spawn, view, and control multiple Claude Code AI coding agent sessions on any device, phone, tablet, laptop, or desktop, by syncing them in real time using an encrypted relay architecture so that a session started on one device can be continued seamlessly on another without losing context. It comprises three coordinated components, a CLI program that runs locally to launch and monitor Claude Code, a mobile app or web app that connects securely to the CLI session using end-to-end encryption so nobody (including the relay server) can read your data, and a relay server that simply passes encrypted blobs between devices without access to the contents; this design lets developers maintain their existing tools, editors, and workflows while adding remote control capability.

About

The open protocol that creates a censorship-resistant global "social" network is based on cryptographic keys and signatures, making it tamperproof. It does not rely on any central server or P2P techniques and is resilient as a result. Everyone runs a client, which can be a native or web version, to publish posts that are signed with their key and sent to multiple relays. Updates from other users are requested by asking multiple relays if they have any information about those users. Any individual can run a relay, which simply accepts and forwards posts without requiring trust. Verification of signatures occurs on the client side.

Pros & Cons from Real Users

Pros

  • Easy to create and setup Android client OpenVibe. I like that I can choose from several clients that just implement the Nostr protocol.

Cons

  • not always as easy as I would like to have it. You still need to figure out how to achieve what you want. But it grows and evolves fast.
