Solon is a Java enterprise application development framework designed as a more restrained, efficient, and open alternative to Spring. It targets Java developers seeking higher performance, reduced memory footprint, faster startup times, and smaller deployment packages, aiming to replace traditional Java EE frameworks.

How It Works

Solon is built from scratch, emphasizing flexible interface specifications and an open ecosystem. It claims significant performance improvements over existing frameworks, including 700% higher concurrency, 50% memory savings, 10x faster startup, and 90% smaller packaging. It supports Java 8 through Java 24 and GraalVM native image compilation.

Quick Start & Requirements

• Installation is typically managed via Maven or Gradle dependencies.
• Requires Java 8 to 24. GraalVM is supported for native image compilation.
• Official examples and plugins for Gradle and IDEs are available.

Licensing & Compatibility

The README does not explicitly state the license. Compatibility with commercial or closed-source projects is not detailed.

Limitations & Caveats

The project is an incubation project under OpenAtom, which may imply a less mature ecosystem or development stage. Specific performance claims should be verified against independent benchmarks. The absence of a clearly stated license could be a concern for commercial adoption.
