About CustomJS
CustomJS is a platform for modern automation workflows. It allows you to generate PDFs from HTML templates, merge documents, capture high-resolution screenshots, host HTML pages and forms, and process incoming emails via Mailhooks.
With CustomJS, collected form data or incoming emails can trigger workflows directly in n8n or Make, making automations seamless and efficient. The built-in form builder simplifies data collection, while Mailhooks enable processing of email content and attachments without extra infrastructure.
The platform also provides lightweight static hosting for landing pages, dashboards, or AI-generated HTML tools. Combined with automated document generation and screenshot capabilities, CustomJS streamlines reporting, invoicing, dashboards, and other workflow-heavy tasks.
Whether you need PDFs, email processing, dynamic forms, or automated screenshots, CustomJS extends your workflow platforms with powerful, ready-to-use capabilities.
