TailClaude: Open Source Web UI for Accessing Claude Code Sessions from Mobile and Browser
TailClaude is an open source, free web UI that provides access to Claude Code sessions from mobile devices or any browser in under a minute, using Tailscale for connectivity.
What TailClaude Does
The tool connects to active Claude Code terminal sessions from mobile or browser without requiring setup on the phone. It offers real-time token streaming with a stop button, cost tracking per message, and markdown rendering. Users can browse, rename, and resume all past sessions with full history. The interface provides controls for model selection (Opus/Sonnet/Haiku), permission modes, effort level, and budget per message. Mobile access works by scanning a QR code from your phone for instant access via Tailscale Funnel, which provides HTTPS connectivity without requiring an app.
How Claude Code Was Used in Development
The developer used Claude Code to scaffold the entire project, including the SSE streaming backend and mobile-first chat UI. Claude helped figure out the Claude Code SDK's session model, write the QR code + Tailscale Funnel integration, and iterate on permission/model selector controls. The developer noted this allowed faster iteration than working alone.
Technical Implementation
The project uses Tailscale Funnel for secure HTTPS access without requiring app installation on mobile devices. The QR code scanning system provides instant connection to sessions. The backend implements Server-Sent Events (SSE) for real-time token streaming, and the frontend includes controls for managing Claude Code session parameters directly from the web interface.
