Happy

What it does

• Full Claude Code sessions from iOS/Android/web — not a truncated terminal mirror
• End-to-end encryption: the relay never sees plaintext code or credentials
• Push notifications for permission prompts and errors; approve from the lock screen
• Session hand-off between devices mid-task; no telemetry collected

When to use it

Best for keeping long agent runs moving while you are away from the desk: kick off a refactor, get pinged when Claude needs a permission decision, approve from your phone.

Getting started

npm install -g happy

# then start sessions with:
happy claude
# or, for Codex:
happy codex

Things to know

Your sessions relay through Happy's infrastructure (encrypted) — self-hosting options exist but add setup work. A phone is a poor code-review surface; treat mobile approvals as triage, not review.
