**Git Worktrees**
- Create new or select existing worktrees when starting sessions. Smart cleanup on delete/archive (checks for uncommitted changes and shared sessions first).
About Happy: Codex & Claude Code App 1.8.0
Keep your coding agents within reach.
Premium
Happy connects your phone to Claude Code and Codex running on your own computer. Start a task, follow its progress, answer questions and review changes from wherever you are.
When an agent stops to ask for permission or a decision, you can answer from your phone. It carries on in the same session, with the same repository, tools and context.
What you can do from your phone
• Start new sessions or continue ones you began at your desk
• Get notified when an agent needs input or finishes
• Approve permission requests and choose how your agent runs
• Pick models and reasoning effort from the providers set up on your computer
• Review changed files and colored diffs
• Attach screenshots and photos to your prompts
• Browse sessions by project and keep drafts in sync across devices
How to connect
1. Install Happy Desktop from happy.engineering.
2. Create an account in this app. No email address or password needed.
3. On your computer, choose Connect phone and scan the QR code it shows.
Prefer the terminal? Install the CLI with npm install -g happy, start an agent with happy claude or happy codex, and scan the QR code it shows.
What you need
• A computer running Happy Desktop or the Happy CLI
• Access to the coding agents you use, through your existing subscription or API key
Private by design
Sessions are end-to-end encrypted, and your encryption keys stay on your devices. Happy's servers relay encrypted session data and can't read your prompts, responses or code.
