Houdin

Houdin is a browser automation extension enabling code injection, script execution, and task automation through a user-friendly interface. It allows users to build automations with a visual workflow designer, inject JavaScript/CSS to modify webpages, and trigger workflows via page loads, clicks, or keyboard shortcuts, all while keeping data local. Houdin supports API extensions, custom scripts, and AI capabilities. It is free to start, with a Plus version in development for advanced features.
