Logseq is an excellent privacy-first, local-first outliner that supports LaTeX formulas. Currently, it relies on KaTeX to render equations, which can cause performance overhead when dealing with large pages of mathematical equations.

Switching to Browser Native MathML
Since Chromium, WebKit, and Gecko support MathML Core natively, Logseq (both Electron desktop app and Web app) can leverage native browser C++ layout engines instead of heavy client-side layout calculators.

We built @webc.site/math, an ultra-lightweight compiler:

• Footprint: Only 3.58 KB (Gzipped, zero-dependency).
• Rendering Speed: Runs at ~329,000 ops/s, making formula rendering during note rendering instant and stutter-free.
• Low Memory Overhead: Avoids spawning nested span trees or loaded fonts in memory, keeping Electron RAM consumption down.

We propose introducing a native MathML compiler mode or plugin for Logseq to provide lightweight, efficient equation typesetting!
