Happy vs FalconDeck

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.

Keep your coding agents moving when you are away. FalconDeck lets you follow live work, answer questions, approve actions, review changes, and send the next instruction from your phone. Pick up the same session on your Mac whenever you are ready. FalconDeck is not affiliated with Anthropic, OpenAI, or Google. Want to see the interface first? Tap "Explore demo workspace" on the welcome screen. It opens a sample workspace with no pairing, no account, and no network. WHAT YOU CAN DO - Keep coding-agent sessions running on your own Mac within reach from your phone - Pick up live sessions from Codex, Claude Code, OpenCode, or other ACP-compatible agents you already use - Get a push the moment an agent needs you — a permission request, a question, or a finished turn - Approve or decline a tool call before anything runs on your machine - Read changes as a proper file-by-file diff, not a wall of terminal output - Dictate a prompt by voice, on-device or through the transcription provider you configure - Attach a screenshot or photo to a prompt - Have long responses read aloud, including when the screen is off - Change agent, model, and reasoning effort per turn - Queue follow-ups and steer a turn while it is still running - Move between projects and threads from one sidebar, and pin, rename, or archive as you go HOW IT WORKS 1. Run FalconDeck on your Mac and open a project 2. Scan the pairing QR code with your phone 3. Your phone joins the same live session — same repository, tools, and context 4. Continue from your Mac or phone whenever you want PRIVACY Session content is end-to-end encrypted between your own devices. The relay that connects them moves sealed ciphertext and holds the keys to none of it, so your prompts, code, and agent output are unreadable to us in transit and at rest. Nothing is used for advertising or model training. If you would rather not use our relay at all, the whole thing is self-hostable. OPEN SOURCE The app, the desktop daemon, and the relay are all public and MIT licensed. Read the encryption, audit the protocol, or run your own: https://github.com/jamesblackwell/falcondeck BUILT FOR - Developers running long agent tasks who do not want to sit and watch them - Anyone who has lost twenty minutes because an agent stopped on a permission prompt two minutes in - People who care where their code goes Privacy Policy: https://falcondeck.com/privacy Terms of Use: https://falcondeck.com/terms
