Visit CustomJS

CustomJS is an automation platform that lets users run custom JavaScript, generate PDFs, capture screenshots, host static HTML pages, build forms, and scrape web data. It is designed to extend no-code workflows when visual automation tools reach their limits, and can be used inside Make.com, Microsoft Power Automate, n8n, or through an HTTP API.

Its capabilities include JavaScript execution with Node.js and npm support, HTML-to-PDF conversion, screenshot capture, static HTML hosting, a drag-and-drop form builder, headless forms, email forwarding to webhooks, a web scraper API, and an MCP server that exposes tools to AI agents. Integrations are available for Make.com and Microsoft Power Automate.

CustomJS is aimed at no-code and AI-powered projects. It offers a free tier with 600 API requests per month, no credit card required, and paid plans with higher daily request limits, more forms, mail hooks, hosted pages, custom domains, and support options. Plans are usage-based, with each JavaScript execution or PDF rendering counting as one request.
