# CustomJS

A toolkit that runs JavaScript, hosts HTML pages, generates PDFs, captures screenshots, and provides a form builder, web scraper, and MCP server for no-code and AI workflows.

**Route:** surfaced by the Web Application and Frontend Hosting Platform lane's de-branded queries → competitor to vercel.com.

**Why it's on the map:** Sells the same web-scraping, PDF-generation, and automation capabilities that a buyer evaluating Vercel would consider for adding programmable logic to their stack.

**Receipts** (verbatim from its page this run):

> Run JavaScript, host HTML pages and forms, and generate PDFs.

> One API for forms, PDFs, screenshots, scraping and more.

> The missing toolkit for what you build.

**Edges:**
