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

OllaCoder is a private AI coding assistant for VS Code, built for engineers who refuse to ship their source code to someone else’s server. It runs locally, works with your own Ollama models, and brings agent mode, inline edits, codebase chat, smart autocomplete, MCP servers, and a local-first runtime into one editor. OllaCoder is built on the idea that software is a private craft: your code should stay yours, and an AI assistant should be powerful, honest, and silent. By default, it talks to your local Ollama instance, so prompts, completions, and edits stay on your computer; cloud providers are strictly opt-in, and API keys live encrypted in the OS keychain. Its agent mode can plan tasks, edit files, run the terminal, and verify its own work, with every step available for approval, denial, or rollback. Inline edits let users highlight a function, describe the change, and review a real diff hunk by hunk.
