1Code
Open source client for parallel AI coding agents
Freemium Coding Open Source
Overview
1Code is an open-source desktop application that provides a polished interface for running AI coding agents like Claude Code, OpenCode, and Codex in parallel. Features dual execution modes (Plan for read-only analysis, Agent for full code execution), real-time visibility into bash commands, file modifications, and web searches. Each conversation operates in isolated git worktrees for safety, with built-in terminal access and visual diff/PR management. Backed by Y Combinator.
