Scalatra is a micro-web framework written in Scala for the JVM. It is lightweight, inspired by Sinatra in Ruby, designed to allow writing web APIs, REST endpoints, and web applications with minimal overhead. It integrates well with existing tools on the JVM, supports asynchronous request handling, templating, filters, and other web framework features, while remaining modular and accessible.

Features

  • Support for simple routing DSL: get, post, put, delete etc with parameter extraction in path or query string
  • Integration with templating engines (views), JSON support etc for building full web apps or APIs
  • Asynchronous request handling and non-blocking IO (for high throughput and responsive behavior)
  • Compatibility with JVM ecosystem: works with Java servlet containers or embedded servers, integrates with SBT, etc.
  • Modular and extendable with filters, middleware-style hooks, and flexible configuration
  • Small core overhead; minimal boilerplate for setting up routes / handlers
