In their own words
Gua
Gua is a free, open-source protocol for testing and automating games made with Godot and Unity. It exposes semantic interface state, including identifiers, roles, text, hierarchy, bounds, visibility, enabled state, values, focus, and selection, so tests and AI agents can query controls and perform actions such as clicking, focusing, setting values, selecting, scrolling, and pressing keys. Tests can wait for interface conditions in NUnit, xUnit, MSTest, or C++ without fixed sleeps. Visual testing compares PNG screenshots with baselines using pixel thresholds, difference ratios, masks, and operating-system or renderer variants. Recording stores semantic actions, timing, revisions, and wait conditions for replay with host checks. Failure artifacts may include UI trees and diffs, pending requests, event history, logs, runtime and environment details, screenshots, and game output. Native MCP connects over WebSocket; WebMCP exposes tools in Godot Web Export and Unity WebGL. Gua documents a Godot 4.7 add-on and Unity 6 support. It targets Windows, Linux, macOS, API, and web environments.
