Sniffy is a comprehensive Java IO/SQL sniffer, profiler, testing, and chaos engineering toolkit. This open-source, native Java software does not require any admin permissions, making it incredibly user-friendly. With Sniffy, you can easily capture and analyze network traffic without the need for third-party software or complicated installations, similar to Wireshark.

One of Sniffy's standout features is continuous Java profiling. By embedding a small widget into your application, Sniffy allows you to monitor and profile its performance in real-time. You can track SQL queries, REST calls, and more, right from the start of your code implementation or during testing in a dedicated environment.

This feature is exceptionally useful for detecting N+1 issues and other performance bottlenecks using unit tests. In addition to profiling, Sniffy offers fault tolerance capabilities. You can simulate loss of connectivity between your server and downstream systems, such as databases, in just a single click.

This feature enables you to test your application's stability under adverse network conditions. Sniffy also provides professional services for those seeking extra guidance and support. While the core functionality of Sniffy is free to use, you have the option to purchase training, development hours, or support plans.

Rates for these services vary based on engagement scope and duration. Stay connected with Sniffy through their Twitter, GitHub, and Stack Overflow accounts for the latest updates and support. Whether you're a developer, tester, or chaos engineer, Sniffy is an indispensable toolkit for optimizing your Java applications and ensuring their smooth operation
