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

OpenCode is the AI coding agent purpose-built for the terminal. It delivers a responsive, themeable terminal UI that feels native while streamlining your workflow. With LSP auto-loading, it ensures the right language servers are always available for accurate, context-aware coding support. Developers can spin up multiple AI agents in parallel sessions on the same project, maximizing productivity. Shareable links make it easy to reference, debug, or collaborate across sessions. Supporting Claude Pro and 75+ LLM providers via Models.dev, OpenCode gives you full freedom to choose your coding companion.

Pros & Cons from Real Users

Pros

  • OpenCode feels like a strong fit for developers who want an AI coding agent without getting locked into one model or one editor. I like that it works in the terminal, desktop, and IDE, so it can fit into different workflows instead of forcing one setup. The model flexibility is a big win. Being able to use 75+ providers, local models, GitHub Copilot, or ChatGPT Plus/Pro makes OpenCode feel more open and customizable than a lot of coding assistants. I also like the LSP support and multi-session workflow. For real coding work, it helps when the agent understands the project better and can run multiple threads of work in parallel.
  • Easy to install Easy to use Free models available with nearly no limits New models commonly get added for free

Cons

  • OpenCode is still something I would supervise closely. Any coding agent that can modify files, reason through projects, and run workflows needs clear review, tests, and good developer judgment.
  • CLI only
