Happy vs Claude Code Remote Control
Claude Code Remote Control is Anthropic's built-in way to continue a local Claude Code session from the Claude app or a browser. Happy is a free, open source app that does the same for Claude Code and Codex, and with Happy Desktop for Grok too, with end-to-end encryption. For Claude-only work with nothing extra to install, Remote Control is simpler.

| Happy | Claude Code Remote Control | |
|---|---|---|
| Made by | Happy Engineering, open source (MIT) | Anthropic, part of Claude Code |
| Agents | Claude Code and Codex through the happy CLI; Claude, Codex, and Grok in Happy Desktop | Claude Code |
| Where the agent runs | Your computer | Your computer |
| Phone and web | Happy for iOS and Android | The Claude app for iOS and Android, and claude.ai/code in any browser |
| Plans | Your existing Claude Code, Codex, or Grok sign-in. Happy Desktop also runs Claude and GPT through Amazon Bedrock | Claude Pro, Max, Team, or Enterprise. Not with API keys, Amazon Bedrock, Google Cloud, Microsoft Foundry, or a custom ANTHROPIC_BASE_URL |
| What the server in between sees | Ciphertext. Your devices hold the keys | The transcript, stored on Anthropic's servers while connected, over TLS |
| Start a new session from the phone | Yes, in a directory you pick | Yes, with claude remote-control (server mode) running |
| When the computer-side process stops | Happy Desktop's sessions belong to a background runtime, so quitting the app does not stop them. The happy CLI keeps a daemon so the phone can start and resume sessions | The session goes offline until you bring it back. Server sessions can be resumed for about four hours |
| Push notifications | Yes, with the happy CLI | Yes, when Claude decides or when an action needs you |
| Organization controls | No admin setting for mobile access | Owners turn it on for Team and Enterprise. Trusted Devices (beta) adds device enrollment and biometric checks |
| Price | Free | Included with the Claude plan |
Where Remote Control is better
- Nothing to install. If you use Claude Code and the Claude app, run
claude remote-control, or/remote-controlin a session, and scan the QR code. - First-party. It works from the Claude Code CLI, the Claude Desktop app, and the VS Code extension, and Anthropic supports it.
- A browser on any computer. Any session opens at claude.ai/code.
- Admin controls. Team and Enterprise owners decide whether it is on. Trusted Devices ties access to an enrolled device and a recent sign-in.
- Deep Claude Code integration. Connected devices see subagent progress, compaction, and a diff pane, and can run commands like
/compactand/model.
Where Happy is different
- More than Claude.
happy codexputs Codex on your phone the same way ashappy claude. Happy Desktop runs Claude, Codex, and Grok in one session and lets you switch mid-session. - End-to-end encryption. Content is encrypted on one device and decrypted on another. Happy's relay stores and forwards opaque blobs; it sees that sessions exist, not what is in them. See Security & Encryption.
- Bedrock. Happy Desktop runs Claude and GPT models through Amazon Bedrock, where Remote Control is not available.
- Sessions that outlive the window. In Happy Desktop a session lives in the runtime, not the app, and survives a restart.
- Open source. The app, the CLI, and Happy Desktop are MIT licensed. Read the code, fork it, ship your own build.
Which one
| You want | Use |
|---|---|
| Claude Code from your phone, with the least setup | Remote Control |
| Claude Code and Codex from the same phone app | Happy |
| Session content that the server in between cannot read | Happy |
| Claude, Codex, and Grok in one desktop app, plus the phone | Happy Desktop |
| Company-managed access with device checks | Remote Control |
