Proof of Usefulness Score
Gaining Momentum

jSparrow is a legitimate Java refactoring tool (Eclipse/Maven plugin) developed by Splendit IT-Consulting GmbH (Austria). While the submission contains grossly exaggerated claims ('most people have used my product', 'audience reach: everyone') and lacks data, independent verification confirms the product exists with approximately 15,000 verifiable installs (Eclipse Marketplace) and a history since ~2019. Recently pivoted to an open-source model (version 4.20.0+). The project has genuine utility for reducing technical debt in Java applications, but the reach is strictly niche (Java developers) and traction is 'small but promising' rather than the claimed mass adoption. The score reflects the solid underlying technology and utility, heavily penalized for the misleading and low-quality submission.
