CustomJS is a backend API service platform designed for no-code/low-code platforms. Its core functions are JavaScript execution, PDF generation and merging, and webpage screenshot capture, primarily for automated document generation and handling complex logic.
CustomJS is natively integrated with these platforms; you can add the corresponding nodes in your workflow (e.g., HTML to PDF node) and use its features without calling external APIs, and it also supports inline coding or invoking stored JavaScript code.
CustomJS uses a freemium model, offering 600 free generations per month. Beyond that, pricing is uniform; please refer to the official pricing page for details.
It is mainly suited for developers, business analysts, and corporate teams who use no-code platforms (such as Make.com and n8n) and require automated document workflows (e.g., invoice and report generation).
Yes. It is based on the Chromium engine and can handle HTML with inline CSS and complex layouts, and supports inserting real-time data (e.g., prices, dates) via JavaScript to achieve highly customized document templates.
As an API service, CustomJS supports security controls such as API key management. However, as it is a preview component, we recommend checking the latest security and compliance documentation before handling highly sensitive data.
