Open-source startups by language.

Every primary language with at least 3 projects in the directory, largest first. Primary language is GitHub’s own field — the language holding the most bytes in the default branch — so a Rust binary with a TypeScript dashboard appears once, under whichever is bigger. 17 of the 3+ groups made the cut against the snapshot of 2026-09-22.
