How AI is used
customJS is a developer-focused toolkit for those needing to fill gaps in standard no-code automation. It supports Node.js execution with NPM module support and converts HTML into PDFs via API, which may help with tasks that standard automation actions cannot handle.
The tool is intended for users who can write code but prefer a hosted environment. It supports static hosting for HTML pages and forms, as well as high-resolution screenshot captures of web views.
Buyers should confirm if they have the technical resources to write the necessary JavaScript or HTML templates, as the platform provides the execution environment rather than a visual drag-and-drop editor. It is designed to integrate with workflow orchestrators such as Make.com and n8n.
