Pele: zero-dependency Mermaid renderer from Obsidian
Obsidian's open-source JS library (obsidianmd/pele) renders Mermaid syntax to SVG — 230kB bundle vs 1.6MB, 0.05–0.3ms renders, zero dependencies, theming via CSS variables without re-rendering; hit ~396 HN points within hours.
Why it matters
Drop-in Mermaid.js replacement that is 6x smaller and claims up to 500x faster renders, with instant theme switching — built by the Obsidian team for their own desktop app.
What you could build with it
A documentation startup could swap Mermaid.js for Pele so diagram-heavy docs render in under a millisecond and follow dark mode for free, cutting load times on technical knowledge bases.
Does it hold up?
Promising — 1274 GitHub stars, npm-installable with a live playground at pele.run; speed claims are project-reported and await independent benchmarks.
