What is Koa?

Koa is a modern Node.js middleware framework from the Express team, built on async/await. This gallery lists 324 open-source projects built with Koa, most of them in DevTools, APIs and Templates, ranked by GitHub stars so the most-adopted repositories come first.

How projects are selected

Projects are public GitHub repositories found with the GitHub search query “topic:koa” and at least 20 stars. Each repository is checked against Koa’s languages and ecosystem before it is categorized, and stars, forks and last-commit dates come straight from the GitHub API, refreshed daily (current snapshot: October 6, 2026). Nothing here is paid placement.
