Does it work with Fastify?

Answer

DocfyModule and the CLI are agnostic to the HTTP adapter. DocfyUiModule now works on both @nestjs/platform-express and @nestjs/platform-fastify apps. On Fastify, static asset serving needs the optional peer dependency @fastify/static (npm install @fastify/static) — the same package @nestjs/swagger itself relies on for Fastify Swagger UI support.
