Good typography serves reading. It creates hierarchy, communicates meaning, and guides the eye through content without calling attention to itself. The best type choice is the one readers never notice.

About
JetBrains Mono was designed specifically for coding, with increased line height, larger punctuation marks, and enhanced disambiguation between similar characters (0/O, 1/l/I). It supports programming ligatures (arrows rendered as →). An excellent choice for code blocks, terminal output, and any technical data display in both developer tools and product UIs.
Use cases

- Terminal output

Usage
✓ Good
Use JetBrains Mono for all code blocks, API key display, and terminal output in developer-facing products.
✗ Avoid
Using JetBrains Mono for headings or body copy — monospace in non-technical contexts reads as awkward and dated.
