Happy vs PixelHQ

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.

Watch your coding agents come to life. PixelHQ transforms your Claude Code sessions into a real-time pixel art office. Every file read, every terminal command, every search — animated as tiny characters working away at their desks in a retro startup office. It's the most fun way to see what your AI coding agent is actually doing. Connect PixelHQ to the lightweight bridge server running on your laptop, and your coding sessions instantly appear as live office activity. Characters read files at their desks, run to the terminal, huddle up for planning sessions, and head to the whiteboard when exploring your codebase. The busier your agent, the busier your office. How it works 1. Run the bridge server on your laptop (`npx pixelhq`). 2. Pair your iPhone with a one-time 6-digit code. 3. Start a Claude Code session and watch your office come alive. The bridge watches your Claude Code session files, extracts only the metadata needed for animations (like event type and tool category), and streams it to the app over your local Wi-Fi. Auto-discovery via Bonjour means no IP addresses to type in — just pair and go. Your code stays on your machine. Period. We take privacy seriously. Here's exactly what happens to your data: - The bridge strips everything sensitive before it ever reaches the app. No source code, no prompts, no AI responses, no file contents, no full file paths — none of it is transmitted. - File paths are reduced to just the filename (e.g. "auth.ts", never the full path). - All communication happens entirely over your local network. Nothing is sent to the cloud or to us. - Pairing is protected with a one-time passcode, and reconnection uses a secure token stored in your device's Keychain. - The only data that leaves your device is anonymous, aggregate usage analytics (app opened, session duration) through TelemetryDeck, a GDPR-compliant, privacy-first analytics provider that collects no personal identifiers. We built PixelHQ local-first by design, not as an afterthought. Your code is your business. Features - Real-time pixel art visualization of Claude Code activity - Automatic bridge discovery on your local network — no manual setup - Secure pairing with passcode protection - Multiple animation states driven by live coding events: file reads, writes, terminal commands, searches, planning, and more - Demo mode to preview the office without connecting to a live session Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://paper-swallow-130.notion.site/Privacy-Policy-2f7b6873ae248098b7ead558245be0bf
