Spark is a tiny, expressive web framework for Java 8+ (with a Kotlin DSL) inspired by Sinatra, letting you define routes with lambdas in a few lines. It bundles an embedded web server so applications can serve HTTP endpoints with minimal setup.

Use cases

• build a rest api in java
• create a simple http server with minimal boilerplate
• serve json endpoints from a jvm app
• prototype a web backend quickly in java
• add lightweight http routing to an existing java application
• learn web development with a small java framework

When to choose

• you want a Sinatra-style microframework in Java with minimal boilerplate
• you need a small REST API or prototype without a heavyweight stack
• you prefer an embedded server and simple lambda-based routing

When to avoid

• you need a full-featured ecosystem with dependency injection, ORM, and async-first design (consider Spring Boot or Micronaut)
• you need high-throughput reactive/non-blocking I/O
• you require active development - releases have slowed and the project appears to be in maintenance mode
