What is Fastify?
Fastify is a low-overhead Node.js web framework for high-throughput APIs and services. This gallery lists 279 open-source projects built with Fastify, 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:fastify” and at least 30 stars. Each repository is checked against Fastify’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.
