Comparison · Checked 1 October 2026 against each product's public documentation · Mirven
Short answer. Claude Code, Codex and Cursor all run agents in parallel, each in its own Git worktree. Mirven builds on Claude Code and Codex and adds what a Unity project needs on top: a written plan where every job owns its folders, scene and asset jobs that take turns, a real Unity build as the check, and a review by a different model before anything reaches you.

"Not built in" means the product's documentation does not describe the feature; you can often build it yourself with scripts and rules. Mirven is in private beta; its app and planner work in Turkish during the beta.
Mirven vs Claude Code agent teams and subagents
Claude Code runs subagents and background agents in their own worktrees, and its experimental agent teams let a lead session coordinate several teammates through a shared task list. Mirven runs Claude Code as one of its builders. What it adds: the plan is written before any code, with owned folders and a finish line per job, so no lead agent has to hold everyone's state in its context; Unity scenes and assets take turns; each job is checked with a real Unity build and reviewed by Codex rather than by another Claude; and nothing merges until you say yes.
Use Claude Code alone for one feature at a time, or when your project has no Unity scenes in play.
Mirven vs OpenAI Codex
Codex runs parallel subagents and gives each desktop chat its own worktree, locally or in the cloud. Mirven runs Codex next to Claude Code in the same plan and uses each to review the other, so a job written by Codex is checked by Claude and the other way round.
Use Codex alone if you only use OpenAI models and want cloud tasks that keep running while your computer is off.
Mirven vs Cursor
Cursor is an editor with parallel agents in worktrees, many model providers and cloud agents that open pull requests. It is not Unity-aware: it does not know that two agents in one scene will collide, and it does not run Unity builds as a check. Mirven is not an editor. It plans and runs agents on your Unity project, and you keep your own editor and IDE.
Use Cursor if you want agents inside your code editor and mostly work on scripts.
Mirven vs Unity AI
Unity AI (beta) puts an assistant inside the Unity Editor, can generate assets, and its AI Gateway runs Claude Code, Codex, Cursor and Gemini CLIs in the Assistant window. Unity also ships an MCP server so external agents can work with scenes and scripts. Its documentation does not describe parallel jobs, worktrees, cross-model review or a merge gate. Mirven works on the project from outside the editor, many jobs at once, and checks each one with a headless build.
Use Unity AI for in-editor help, asset generation, and one agent at a time inside the editor.
Mirven vs Conductor, Claude Squad and other orchestrators
Conductor, Claude Squad and similar tools run Claude Code, Codex and other agents in parallel worktrees and let you review the diffs. They are general-purpose and do not know Unity. Mirven is built for Unity projects: scene lanes, real builds as checks, review by a different model, and project memory that gives each job only the notes it needs.
Doing it yourself
All of this works with plain Git, Claude Code, Codex and a few scripts. We published ours, MIT: unity-parallel-agents on GitHub, and the full guide.
