1Code

About 1Code

1Code is an open-source, Cursor-like interface built to run Claude Code agents in parallel on Mac and the Web. It offers local execution on macOS (with optional worktrees) and remote sandboxes with live previews, including mobile previews.

Review

1Code focuses on making it easier to run multiple Claude Code agents at once and to inspect their results quickly. By combining a graphical UI with integrations that rely on the Claude Code CLI, it aims to reduce friction when developing and testing AI-driven code workflows.

Key Features

• Parallel agent execution: run multiple Claude Code agents concurrently to speed up development tasks.
• Mac-first local mode: run agents locally on macOS, with or without worktrees for workspace isolation.
• Web-based remote sandboxes: start agents remotely and get live previews of web and mobile apps from anywhere.
• Open-source codebase and easy build: source is available and can be built locally (example: bun build).
• Claude Code CLI compatibility: uses the existing CLI under the hood and accepts the same authentication methods.

Pricing and Value

1Code is offered with an open-source core, so there are free options for users who want to self-host or build from source. Paid tiers are available and are expected to add managed features or higher usage limits; purchasing tiers can also serve as a signal of adoption for the project. Note that access to model execution itself typically requires a Claude Code API key or subscription, so model costs and subscription constraints are separate from 1Code's hosting or feature tiers.

Pros

• Open-source with a familiar, cursor-style UI that lowers the barrier to entry for experimenting.
• Supports parallel agents, which can accelerate feature development and testing workflows.
• Flexible deployment: run locally on Mac or in remote sandboxes with live previews for quick verification.
• Integrates with the Claude Code CLI so existing setups and keys are compatible.
• Active roadmap promises QA and bug-detection agents and support for more models in future releases.

Cons

• Model access depends on the Claude Code CLI and its subscription or API key requirements, adding an external dependency and potential cost.
• Several useful capabilities are listed as planned rather than available today, so some users may find current features limited for larger teams.
• Because the project is new, expect some rough edges in the UI and integrations until the project matures.

1Code is best suited for developers and small teams who are already using Claude Code and want a faster, GUI-driven way to run and observe multiple coding agents. It's also a good fit for front-end developers who benefit from live previews and for contributors who prefer open-source projects and are comfortable with early-stage tooling. If you need a mature, fully managed multi-model platform today, you may find some features are still on the roadmap.
