1Code is an application designed to run Claude Code agents in parallel, providing a visual interface for working with Anthropic's Claude Code AI coding assistant. It offers both Mac and Web versions, allowing developers to run agents locally or in remote sandboxes with live previews.

The product enables parallel agent execution, allowing users to work on multiple features at once by running agents locally, in worktrees, or in the background. It provides full Claude Code functionality including plan mode, skills, and message editing capabilities. The interface is keyboard-first with hotkeys for every action, enabling navigation, creation, and management without mouse interaction.

Users start by signing in with their Anthropic account, which utilizes their existing Claude Pro/Max subscription. They can then launch agents from either the web interface or macOS application. The system allows shipping directly from the UI with capabilities to open PRs and merge changes without context switching.

The main benefits include dramatically speeding up feature development through parallel agent execution and providing flexible deployment options with local Mac operation or remote web-based sandboxes with live previews. Users can check on agents from anywhere when using the web version.

The target audience is developers who use Claude Code for AI-assisted programming, particularly those working on multiple features simultaneously. The product integrates with Anthropic's Claude Code platform and GitHub workflows, supporting both self-hosted local deployment and cloud-based operation.
