}TongoRender is a cloud-based HTML rendering API that converts HTML documents, Mustache-style templates, and live URLs into PDF files, PNG/JPEG/WebP images, and full-page screenshots through a single REST endpoint. Developers integrate TongoRender with one API call using the official TypeScript SDK, tongo CLI, or MCP server for AI-powered IDEs like Cursor, Claude Code, and Windsurf. Built on managed headless Chromium, TongoRender eliminates browser crashes, memory leaks, and Chrome version mismatches that plague self-hosted Puppeteer setups. With sub-2-second average render times, a 99.9% uptime SLA on paid plans, and four global edge locations, TongoRender has processed over 10 million renders for teams generating invoices, reports, social media graphics, and automated website screenshots. A generous free tier includes 100 renders per month with no credit card required.

Loved by Developers
See what developers are saying about TongoRender
"Replaced our entire Puppeteer setup with 3 lines of code. Our invoice generation went from 12 seconds to under 2. The TypeScript SDK is beautifully designed."
Sarah Chen
Lead Engineer at Vercel
"The CLI tool is a game changer for our CI/CD pipeline. We generate 15k+ reports per day and haven't had a single timeout. The MCP Server integration with Cursor is chef's kiss."
Marcus Rodriguez
CTO at Stealth Startup
"We evaluated PDFShift, DocRaptor, and API2PDF before choosing TongoRender. Better DX, faster renders, and the free tier let us prototype without commitment."
