Rendex
Rendex is an API-driven rendering service designed for developers and AI agents who need to convert HTML, URLs, or Markdown into images or PDFs as part of automated workflows. The platform focuses on enabling fast, reliable rendering for use cases such as generating charts, reports, social cards, thumbnails, and PDF documents directly from code or automation tools.
The service operates via a REST API, allowing users to send a POST request with HTML, a URL, or Markdown content, optionally using a data object to fill templates. Rendex processes these requests using a headless Chromium engine deployed at edge locations close to the caller, aiming to minimize latency and avoid infrastructure management on the user's side. Output options include receiving a PNG or PDF stream, a redirect to a signed URL, or delivery via webhook. The same rendering engine is used across all plans, regions, and interfaces, supporting consistent results regardless of how it is accessed.
Rendex integrates with popular automation and workflow platforms, including n8n, Make, and Zapier, as well as with AI agents over the Model Context Protocol (MCP). Official integrations provide native or template-based actions, such as rendering HTML, URLs, or Markdown and piping results into other services like Drive, Slack, or Notion. The n8n integration offers multiple render modes and simple authentication, while the Zapier integration includes presets for common rendering tasks. The MCP endpoint enables AI agents like Claude and Cursor to invoke rendering as a tool call within their workflows.
The platform is positioned as a rendering API for automation, with a focus on ease of integration, batch processing, signed webhooks, and global edge distribution.
