markdown-svg-renderer — View Mozilla Bugzilla bug reports and render formatted markdown content with live preview. Paste markdown directly or load from a raw URL or GitHub Gist, with support for standard markdown formatting, tables, code blocks, and interactive SVG previews with tabbed display. Toggle between editor and full-screen viewer modes to focus on the rendered output.
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 where it loads a Markdown file full of LLM pelican logs for Opus 4.8.
