1Code
Officially listedA visual platform for orchestrating multiple Claude Code and Codex agents in parallel.
1Code
1Code is an open-source visual orchestration platform for AI coding agents built by 21st.dev (YC W2026), providing a GUI for Claude Code and Codex. Its core selling point is letting multiple AI agents work in parallel - one each for frontend, backend, and testing, without interfering with each other. GitHub 5.2k Stars and Product Hunt #1 of the day.
Core Capabilities
- Parallel agent execution: Run multiple Claude Code/Codex agents simultaneously, each isolated in its own Git worktree
- Multi-agent switching: One interface supports both Claude Code and Codex so you can pick the best model per task
- Background cloud execution: Agents keep running in the cloud even after you shut down your computer, with results and live previews waiting when you return
- MCP plugin marketplace: Integrates your development toolchain including Notion, Linear, GitHub, and Slack
- Automated triggers: Mention @1code in GitHub/Linear/Slack to launch a background agent
- REST API: Create tasks programmatically; agents automatically wire up repositories and dependencies in a cloud sandbox
Use Cases Best for advanced developers and small teams already using Claude Code deeply who need to handle multiple development tasks at once. If you only occasionally use AI to assist with coding, Cursor may be a better fit.
Unique Advantages It is not an IDE replacement but an orchestration layer - Cursor enhances a single agent, 1Code runs many in parallel. Open source under Apache 2.0 so it can be audited, keyboard-first design fits terminal users' habits, and background agents with live previews are capabilities unique to this category.
Editor's Review Parallel agents solve a real pain point for Claude Code users, and the 3-person team iterates extremely fast, though the product is still at v0.0.x. Watch total cost: 1Code Pro at $20/month plus Claude Max at $100/month comes to $120/month. Worth trying, but be prepared for the instability of an early-stage product.

FAQ
Is 1Code free?
The open-source edition is completely free (Apache 2.0), Pro is $20/month with background agents and mobile, and Max is $100/month with automation features. LLM costs are separate, requiring an Anthropic or OpenAI subscription.
What can 1Code be used for?
It provides a visual GUI for Claude Code and Codex, centered on letting multiple AI coding agents run different tasks in parallel, with Git worktree isolation, background cloud execution, and automated triggers.
How does 1Code differ from Cursor?
Cursor is a full IDE replacement focused on single-agent code completion. 1Code is not an IDE; it is an agent orchestration layer whose core value is multi-agent parallelism - you keep writing code in your own editor.
How does 1Code avoid code conflicts between parallel agents?
Each agent runs in its own Git worktree, modifying separate copies of the code; when finished, changes are merged through the standard Git PR workflow, so code is never accidentally overwritten.
Which AI coding agents does 1Code support?
It currently supports Claude Code and OpenAI Codex agents, switchable per task in the same interface. Cross-platform support covers macOS, Windows, and Linux desktops plus Web/mobile PWAs.
Is a 3-person team reliable enough for 1Code?
The team is backed by YC W2026 and the founders have multiple successful startups behind them (Via processed $1.5B+ in transaction volume). The open-source community helps maintain it, but the product is still iterating quickly at v0.0.x.
