markdown-svg-renderer

Simon Willison released a new Markdown rendering tool that treats fenced code SVG blocks as rendered images while also offering a code view tab. The tool accepts pasted Markdown or URLs to CORS-enabled Markdown files and Gists, enabling users to preview and toggle between rendered SVG images and their source code.

Tool: markdown-svg-renderer https://tools.simonwillison.net/markdown-svg-renderer A slightly customized Markdown rendering tool with special treatment for fenced code SVG blocks - it both renders the image and provides a tab for switching to the code view. You can paste in Markdown or give it a URL to a CORS-enabled Markdown file or Gist. Here's an example https://tools.simonwillison.net/markdown-svg-renderer url=https%3A%2F%2Fgist.github.com%2Fsimonw%2Ffea4f7546626d627862dc241a4e3a86a where it loads a Markdown file full of LLM pelican logs for Opus 4.8 https://simonwillison.net/2026/May/28/claude-opus-4-8/ and-some-pelicans .
