Midscene

Midscene is an AI-powered GUI agent that automates end-to-end testing and UI workflows using natural language.

Midscene is a vision-driven GUI agent for end-to-end testing and UI automation across web, mobile, and desktop applications. It allows developers to write tests in natural language or YAML, integrating with tools like Playwright and Puppeteer or running via bridge mode and CLI. The system uses computer vision models to observe interfaces, locate elements that lack selectors such as canvas or native apps, perform actions, and verify results. Users can choose from multiple models including DeepSeek, Qwen, GPT, Gemini, Kimi, and Doubao Seed, and combine planning and vision models to optimize costs and task completion rates. It also features visual reports, playgrounds, and drop-in skills for AI coding agents.
