Description

Happy, often referred to as Happy Coder, is a free and open-source client available for both mobile and web platforms, allowing users to create, observe, and manage multiple sessions of Claude Code AI coding agents across a variety of devices including phones, tablets, laptops, and desktops, all while ensuring real-time synchronization through an encrypted relay system that enables users to continue their work on different devices without any loss of context. This system features three interconnected components: a locally running CLI program that launches and oversees the Claude Code sessions, a mobile or web application that securely connects to the CLI via end-to-end encryption to protect user data from being accessed by anyone, even the relay server, and a relay server that merely transmits encrypted data between devices without accessing the information itself; this architecture allows developers to use their preferred tools, editors, and workflows while integrating remote control functionalities effortlessly. Additionally, the seamless transition between devices promotes enhanced productivity and flexibility for users engaged in coding tasks.

Description

OpenCode brings AI-driven development directly into the terminal with a sleek, native TUI that adapts to your preferred theme and style. Its LSP-enabled architecture automatically detects and configures the best tools for each language, ensuring seamless coding assistance across stacks. Unlike typical agents, OpenCode is designed for true multi-session workflows, allowing multiple agents to run in parallel on the same project without conflict. Developers can instantly generate shareable links from their sessions, making debugging and collaboration smoother than ever. With support for Claude Pro, Claude Max, and over 75 different LLM providers through Models.dev—including local models— OpenCode offers unmatched flexibility. Installation is simple across npm, Bun, Homebrew, and Paru, giving developers fast access no matter their setup. Beyond the terminal, OpenCode integrates with VS Code and GitHub, extending AI power across familiar environments. For coders who want speed, flexibility, and direct control in their workflows, OpenCode is the definitive AI agent for the command line.
