How to use Claude Code from your phone

Yes and no. Anthropic offers Remote Control inside Claude Code. You can open the session from the Claude iOS or Android app, or from claude.ai/code in a browser. There is no separate Claude Code mobile app — it is a feature within Claude's existing surfaces.

Yes. It requires an eligible Anthropic plan: Pro, Max, Team, or Enterprise. API keys are not supported, and Team/Enterprise require admin enablement. There is no standalone price for the feature.

Yes. Happy Coder’s public README documents end-to-end encryption for its session traffic, so ordinary sessions do not have to use Anthropic’s Remote Control path. It does not currently document a self-hosted relay. Sesori end-to-end encrypts ordinary session payloads between the phone and local Bridge. Its relay still handles routing metadata, while model providers and optional hosted features keep separate data paths.

Most mobile clients listed above are Claude Code-only (or Claude Code plus Codex). Sesori supports OpenCode, Codex, Cursor, Claude Code, Pi, OMP, and Hermes today and lets you pick which one a session runs on from the app, so you keep one mobile cockpit across whichever assistant you happen to be using.

There is no universal answer because the host, relay, model provider, and optional features all affect the data path. Happy Coder’s public README and Sesori’s documentation describe end-to-end encryption for ordinary session payloads. The CodeAgent Mobile product page reviewed for this guide does not describe an equivalent boundary. Claude Code Remote Control routes through Anthropic infrastructure under its terms.
