Happy vs ZyCin · AI SSH Remote Coding

Your coding agent shouldn't wait for you to get back to your desk. A task can run for an hour and then stop five minutes in to ask for permission or a decision. Happy lets you answer from your phone, and the same agent carries on in the same repository with the same tools and context. Happy is the mobile app for Claude Code and Codex. The agents keep running on your own computer, and your phone is how you start them, steer them and review their work. WHAT YOU CAN DO FROM YOUR PHONE • Start a new session or pick up one you began at your desk • Get notified when an agent needs input or finishes • Approve or deny permission requests, or let a session run in Auto mode • Choose the model and reasoning effort from the providers set up on your computer • Review changes: a file list, colored diffs, and the full set of changes on a branch • Attach a screenshot or photo to your prompt • Browse sessions in one list or grouped by project, with each checkout's chats as tabs • Open a side chat next to a session without losing your place • Drafts follow you between your phone and your computer HOW IT WORKS Happy runs on your computer, and this app connects to it. 1. Install Happy Desktop from happy.engineering, or if you prefer the terminal, run: npm install -g happy 2. Create an account in the app. You don't need an email address or a password. 3. Scan the QR code your computer shows to link it to your phone. Then start a session from either device. What you see on your phone is the same live session that's running on your computer. YOU WILL NEED • A computer running Happy Desktop or the Happy CLI • Access to the coding agents you want to use, such as a Claude or ChatGPT/Codex plan or API key. Happy uses your existing accounts. PRIVATE BY DESIGN Sessions are end-to-end encrypted. Your code, agent and encryption keys stay on your devices. Happy's servers only relay and store encrypted session data and can't read your prompts, responses or code. OPEN SOURCE The app, the CLI and the server are MIT-licensed and on GitHub. Read the code, run your own build or host your own server. ALSO ON DESKTOP Happy Desktop adds a harness that works across providers and lets you switch models in the middle of a task. The sessions it starts show up on your phone too. Happy is an independent project. It is not affiliated with or endorsed by Anthropic or OpenAI. Claude and Claude Code are trademarks of Anthropic. Codex and ChatGPT are trademarks of OpenAI. Privacy Policy: https://happy.engineering/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Code from your phone. Connect to your server. On the road, on the train, or putting out a fire — no laptop needed. Tell ZyCin what you want in plain language. It connects to your server over SSH, reads the code, edits it, runs commands and tests, and gets the job done. CORE FEATURES · Conversation as development Describe a task in one sentence. The agent runs the full loop — read files → analyze → edit → verify — with every tool call and code change visible in real time. · Direct SSH to your server Password or private key login. Works with Linux, macOS and Windows (PowerShell). Your code stays on your server — never routed through us. · Multi-protocol file manager Browse and edit over SSH / SFTP / FTP / FTPS / WebDAV, with an icon grid, syntax highlighting and in-place saving. · Switch models freely 175+ built-in provider presets (OpenAI, DeepSeek, Anthropic, Gemini, Kimi and more). Switch models mid-conversation. · Scan for local LLMs Auto-discover Ollama / LM Studio / llama.cpp / vLLM on your LAN — free, offline, and your data never leaves the network. · Image and voice input Send a screenshot so the AI can see the error or the UI. Hold to talk and assign tasks by voice. · MCP extensions Connect MCP (Model Context Protocol) servers to give the agent databases, APIs, Kubernetes and more. · Secure by design Passwords, keys and API keys are stored only in the device secure storage. Writes and command execution ask for confirmation by default, with dangerous commands highlighted. Host fingerprints are pinned on first connect and flagged if they change. WHO IT IS FOR · DevOps and backend engineers who must react to production issues anywhere · Developers who review code and fix bugs on the commute · Indie developers and remote teams NOTES · Bring your own model API key, or use a local model on your LAN. Connecting to a server requires you to have the appropriate access. · New users get a 30-day free trial; afterwards the free tier allows 40 messages per day.
