Happy Coder is the secure mobile companion for Codex and Claude Code that lets you continue your AI coding sessions anywhere (not affiliated with Anthropic or OpenAI). Built by developers who needed to check on their AI assistant's progress during coffee breaks, this app brings the full Codex and Claude Code experience to your phone with military-grade encryption. **Important**: This app requires Codex or Claude Code to be installed on your computer. Happy Coder is a companion app that connects to your existing Codex or Claude Code setup. **Key Features:** - Continue Codex and Claude Code sessions seamlessly between desktop and mobile - Push notifications for permission requests and task completion - Access conversation history even when your terminal is offline - End-to-end encryption - your code stays private - Real-time streaming of AI responses - Zero-knowledge architecture - we can't read your data **How It Works:** 1. Install the happy-coder CLI on your computer 2. Scan a QR code to securely pair your devices 3. Use 'happy' instead of 'codex' or 'claude' to start encrypted sessions 4. Switch between desktop and mobile instantly Perfect for developers who: - Want to monitor long-running tasks on the go - Need secure access to proprietary code discussions - Value privacy and open-source transparency - Work from coffee shops, trains, or anywhere Happy Coder uses the same encryption as Signal (TweetNaCl) and is completely open source. Your encryption keys never leave your device, and all data is encrypted before transmission. Built by Bay Area engineers who believe the best tools come from scratching your own itch. We needed a way to securely check on our AI coding assistant while away from our desks - so we built it and shared it with the community. Your code. Your privacy. Your Codex and Claude Code companion. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Send a prompt to Claude Code, opencode or Oh My Pi from your phone, pocket it, and watch the turn finish on your Lock Screen. Approve the risky command, answer the agent's question, read every diff — from anywhere on your own Tailscale network. WHAT YOU NEED A Mac or Linux machine on your tailnet (Tailscale is free for personal use) running one of your agents: opencode, Claude Code through the open-source claude-bridge, or Oh My Pi through the open-source omp-bridge. Set-up is three verified steps, and a built-in demo lets you try every screen before you wire anything. THE TURN, LIVE ON YOUR LOCK SCREEN • A Live Activity per conversation: what it is doing, for how long, and how many tools it has run. • An approval request alerts you; a finished turn lingers with its outcome. Tap to land in the exact chat. • Updates arrive by push while the app is suspended. A NATIVE TRANSCRIPT, NOT A TERMINAL • Streaming text written at the model's own speed, with thinking and tool runs folded into readable groups. • Diffs, commands and their real output inline; syntax-highlighted code with byte-exact copy. • Allow once, always, or deny — without leaving the chat. Agent questions become tappable cards. • Queue the next message while a turn runs, edit it before it goes, or stop the turn on the server. • Every picture the agent hands you, in a gallery you can zoom, save or share. EVERY MACHINE ON ONE BOARD • All your servers' conversations in one list, live status first, grouped by project. • Read the repository before you trust the change: branch, staged, changed, untracked, and the diff of any file. • Subagents dock inside the turn that spawned them; a compaction is drawn as a seam with what it kept. • Slash commands from the server's own catalog, per-message model and reasoning effort, forking. KNOW WHAT IT COSTS • Every conversation priced, every month totalled across machines — by model, project and tool. • Plan limits and quotas for Claude, Grok, Ollama Cloud, DeepSeek and more, on Home and in a widget. YOURS, END TO END • Point-to-point over your tailnet. No relay servers, no account, no analytics, nobody reading your code. • Programmatic UIKit, Swift 6, Liquid Glass on iOS 26. Dark mode, Dynamic Type, haptics. • Open source under GPL-3.0 — the app, the engine, and both bridges. FREE, WITH AN HONEST PRO The free app is the complete core: one server, full chat, approvals, attachments, models, forking, and Live Activities. Tailscode Pro is a one-time purchase, no subscription: multiple saved servers, concurrent Live Activities, and a supporter badge. Tailscode is independent open-source software: not affiliated with or endorsed by Anthropic, Tailscale Inc., the opencode project or Oh My Pi.

Verdict

The call

The clearest difference is ratings volume: Happy at 991 against Tailscode's 1. Happy also leads on chart position (#100 vs unranked) and iOS requirement (15.1 vs 18.0). Tailscode's advantage is update cadence (every 2 days vs weekly). On price, rating, ads and in-app purchases there is nothing between them.
