TypeScript Overtakes Python and JavaScript To Claim Top Spot on GitHub

TypeScript overtook Python and JavaScript in August 2025 to become the most used language on GitHub. The shift marked the most significant language change in more than a decade. The language grew by over 1 million contributors in 2025, a 66% increase year over year, and finished August with 2,636,006 monthly contributors.

Nearly every major frontend framework now scaffolds projects in TypeScript by default. Next.js 15, Astro 3, SvelteKit 2, Qwik, SolidStart, Angular 18, and Remix all generate TypeScript codebases when developers create new projects. Type systems reduce ambiguity and catch errors from large language models before production. A 2025 academic study found 94% of LLM-generated compilation errors were type-check failures. Tooling like Vite, ts-node, Bun, and I.D.E. autoconfig hide boilerplate setup. Among new repositories created in the past twelve months, TypeScript accounted for 5,394,256 projects. That represented a 78% increase from the prior year.
