What is unity-cli?

unity-cli is a single-binary tool built in Go that lets you control the Unity Editor from your terminal—no Python relays, MCP protocols, or runtime dependencies needed. Drop in a lightweight C# connector package via Git URL, and run commands like `unity-cli editor play --wait`, `exec "Selection.activeGameObject.name"`, or `reserialize Assets/Player.prefab` to toggle play mode, run arbitrary C# scripts, read console logs, execute menu items, refresh assets, or inspect profiler data. It solves the pain of manually clicking through Unity for repetitive tasks, enabling scripted workflows over direct HTTP to localhost.

Why is it gaining traction?

Unlike MCP setups with thousands of lines of JSON-RPC and WebSocket bridges, this is dead simple: one binary discovers Unity instances via a status file and fires HTTP POSTs. The killer feature is `exec` for instant C# execution with full Unity API access—query scenes, spawn objects, tweak PlayerSettings—plus safe asset reserialization after YAML edits and auto-discovered custom tools via attributes. Developers dig the zero-install friction and shell compatibility on Linux, macOS, Windows.

Who should use this?

Unity scripters automating builds, asset pipelines, or tests; AI agent builders needing programmatic editor control like unity cli github integrations for scene tweaks or profiler dumps; solo devs handling unity click on gameobject queries or unity control animation from script without custom editors. Ideal for github control panel workflows in monorepos with Unity projects.

Verdict

Grab it if you need lightweight Unity CLI control—docs are thorough, MIT-licensed, and cross-platform—but with 22 stars and 1.0% credibility score, treat as experimental for production. Test in a side project first; maturity lags behind battle-tested alternatives.
