Key Features
Natural Language Interaction
Execute actions like 'click the login button' or 'type hello in the search bar' without writing code.

Extract structured JSON data from any webpage by simply describing what you need.
Visual Debugger
A dedicated UI to replay steps, see what the AI saw, and understand why specific actions were taken.
Self-Healing Tests

Pricing Breakdown
Midscene.js is an open-source, MIT-licensed software that is free to use. However, a compatible multimodal AI model needs to be configured separately and may incur API costs from the model provider.
