Happy vs Pragma Sh Go

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/

Pragma Go is the mobile companion to Pragma, the desktop workspace for running coding agents in parallel. Pair it with Pragma on your Mac, Linux, or Windows computer and take your whole workspace with you: every project, worktree, agent, and terminal, live. REAL TERMINALS Open a shell on your computer and type into it. A terminal you open on the phone is a real tab: it shows up on the desktop too and survives a restart. A key bar adds the keys a phone keyboard lacks (ctrl, esc, tab, ^C, and the arrows). The phone borrows the terminal's size while you look and hands it back when you leave, so your desktop layout is never disturbed. A dropped connection picks up where it left off, and a keystroke is never sent twice. LAUNCH AND STEER AGENTS Create worktrees and launch Claude Code, Codex, Cursor, opencode, and other agents, picking the model and reasoning effort for each. Follow a session as a chat or switch to its raw terminal. Answer agent questions and approve commands, the same prompts the desktop shows, from wherever you are. FAN OUT Send one prompt to several agents at once and compare the attempts side by side. Swipe between them, read every file each one changed, send follow-ups to all of them or just one, and pick the winner to merge. COMMIT & PULL REQUEST Tap once to have AI group your changes into logical commits, then review the title, description, and base branch before anything is pushed. Your computer runs the job, not your phone: locking the screen or losing signal won't cancel it or start it twice. PROJECT SCRIPTS AND PORTS Start your dev server or any project script with a tap, and stop it the same way. See which ports your worktree is listening on and open them in your phone's browser through your own tunnel, with a design mode for pointing at an element and asking an agent to change it. FILES, DIFFS, AND SCRATCHPADS Browse a worktree's files with syntax highlighting, read diffs, and read and comment on the scratchpads and whiteboards your agents write. ACCOUNTS AND USAGE See every agent account's plan usage and when it resets, and switch which account an agent launches with. WIDGETS AND NOTIFICATIONS Home Screen and Lock Screen widgets show agents waiting on you, live agent status, pending approvals, and your projects. Push notifications tell you when an agent finishes or needs an answer, and stay quiet while you're at your desk. PRIVATE BY DESIGN Pragma Go talks only to your own computer, over a tunnel you control. Pair it by scanning a QR code, and every request needs your device's token. Your code never passes through Pragma's servers. Requires the free Pragma desktop app (macOS, Linux, or Windows), available at pragma.sh.
