What is 1Code?

Editorial review
1Code by 21st is an open-source client designed to enhance the experience of working with Claude Code. It allows users to run multiple AI agents in parallel, either locally, in worktrees, or in the background, significantly boosting productivity for developers working on complex projects. The platform integrates all the familiar features of Claude Code, such as plan mode, skills, and message editing, within a streamlined and calm user interface. Key benefits include a keyboard-first UI for efficient navigation and action execution, direct integration with Anthropic accounts (requiring a Claude Pro/Max subscription), and the ability to launch agents from both web and macOS apps. 1Code also facilitates a complete development workflow by allowing users to open PRs and merge changes directly within its interface, minimizing context switching. It's ideal for developers seeking to leverage Claude Code's capabilities more effectively and manage multiple AI-assisted tasks simultaneously.
