Fastify vs Play Framework

Fastify has no write-up on Specifiction yet; its figures are above.

Play Framework is a free, open-source full-stack framework for building applications in Java or Scala. It supports server-side rendering and includes an ORM for database mapping. Applications are deployed on self-hosted infrastructure, so teams use their own hosting environment. The framework is available on Linux, macOS, and Windows. Its listed capabilities make it relevant to developers choosing a framework for server-rendered applications with database mapping included. The open-source license model means there is no listed software charge. One notable omission is built-in authentication: teams that need authentication will have to address that separately. Play Framework’s defined scope here is centered on Java or Scala, server-side rendering, an included ORM, and self-hosted deployment. Those details help clarify both its framework coverage and the infrastructure and access-control decisions teams must make around an application.
