Best UI for Claude Code with local and remote agent execution.

By 21st.dev team

Note: Currently tested on macOS and Linux. Windows support is experimental and may have issues.

• Plan & Agent Modes - Read-only analysis or full code execution permissions
• Project Management - Link local folders with automatic Git remote detection
• Real-time Tool Execution - See bash commands, file edits, and web searches as they happen
• Git Worktree Isolation - Each chat session runs in its own isolated worktree
• Integrated Terminal - Full terminal access within the app
• Change Tracking - Visual diffs and PR management

# Prerequisites: Bun, Python, Xcode Command Line Tools (macOS)
bun install
bun run claude:download  # Download Claude binary (required!)
bun run build
bun run package:mac  # or package:win, package:linux

Important: The claude:download step downloads the Claude CLI binary which is required for the agent chat to work. If you skip this step, the app will build but agent functionality won't work.
