Pele – Mermaid diagrams as themeable SVG

Pele renders Mermaid diagrams up to 500× faster than Mermaid.js

Pele is a zero-dependency renderer that turns Mermaid syntax into themeable SVG. It supports every diagram type in Mermaid 12.1.0, ships at 230 kB gzipped versus 1.6 MB, and renders in 0.05–0.3 ms compared to Mermaid.js's 6–82 ms. Colors and fonts are set via CSS variables without re-rendering. Developed for Obsidian and open source, it adapts layouts to small screens.

Zero dependencies, 6× smaller, and up to 500× faster than Mermaid.js.

    Anytime I try mermaid for anything more complex than a toy diagram I always end up absolutely frustrated by the arcane and topologically poor layout that is produced.

    Styling seems like a trivial problem by comparison.

    Tools like this are so amazing because they allow Claude to edit and draw and save to a single markdown file. So practical! Version control friendly. People can use them, sure. Buy AI can really take off with tools like this.

    Is pele open source?

    I tried to find the source code of it but I was unable in finding so

    Edit: found it, https://github.com/obsidianmd/pele

    Also folks, this is a good reminder to please have a github icon on the top of the page to easily show git/github links if the app is open source, also helps in the fact that I can star your projects and bookmark them more easily :-D

More from this day
