Pele
What we like
Renders Mermaid syntax to SVG. Colors and fonts are customizable through CSS. Zero dependencies. Responsive layouts and very fast render times (under 1ms).
What we don't like
Doesn’t support all diagram types or Mermaid plugins.

Interesting tools
Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
KiviDB
What we like
Redis-compatible protocol, including search, vectors, and Lua scripting. Commands run on every core rather than one thread. Claims faster performance than Redis, including better p99 latency. Runs on a different port by default. Written in Rust.
What we don't like
Licensed under AGPL.
