When looking for open source alternatives for Java applications, the following criteria should be considered: functionality, stability, active development, documentation, and license. For HTTP client alternatives, it is recommended to consider: 1. OkHttp (full-featured, maintained by Google); 2. Jetty HttpClient (high-performance, from Eclipse Foundation); 3. Retrofit (type-safe, used for Android development). Choosing the most appropriate alternative depends on application needs and priority factors such as functionality, performance, team preference, and license compatibility.

• Supports HTTP/2 and WebSockets and provides a wide range of configuration options.
• License: Eclipse Public License v2.0

3. Retrofit

• A type safety tool for Android development HTTP client.
• Simplifies API calls and provides code generation tools.
• License: Apache 2.0

Decision Factors:

Choosing the best alternative for your application will depend on your specific needs and priorities. Here are some factors to consider:

• Features you need
• Application performance requirements
• Your team’s experience and preferences
• Licensing Certificate Compatibility

By carefully evaluating alternatives and considering real-world use cases, you can find the most suitable open source alternative for your Java application.
