The best languages mods

15,047 mods in the catalogue carry this category. These 100 are the ones that pass every gate. Every gate: original work, not a copy · security scan A or B · a licence that permits reading the source · an actively maintained repository people actually use. Order is the composite score — reputation, freshness, safety, originality, content and traction — not anyone's opinion.
