1Code is an application designed to run Claude Code agents in parallel, providing a visual interface for AI-assisted coding. It offers both Mac and web versions, with the Mac version running locally (with or without worktrees) and the web version running in remote sandboxes with live previews including mobile support.

The product includes parallel agents capability for working on multiple features at once, full Claude Code power with features like plan mode, skills, and message editing, and a keyboard-first UI with hotkeys for every action. Users can navigate, create, and manage without touching their mouse, and the interface supports opening PRs and merging changes directly.

To get started, users sign in with their Anthropic account using their Claude Pro/Max subscription. They can then launch agents from either the web or macOS app, with the same power available across platforms. The workflow allows shipping directly from the UI without context switching.

The benefits include dramatically speeding up feature development through parallel Claude Code execution. Use cases involve building features more efficiently by running multiple AI coding agents simultaneously across different environments.

Target users are developers working with Claude Code who want improved productivity through parallel execution. The product integrates with Anthropic accounts and GitHub, and technical details include local Mac execution or remote web sandboxes with live previews.
