Score: 4.0/10 (Innovation: 4, Technical: 3, Documentation: 2, Utility: 5)

Sentrint is a collection of free client-side security and JSON utilities (header inspection, CSP testing, scan comparison) that run entirely in the browser without uploading user data. The privacy-first, no-account model is appealing for quick ad-hoc checks, but it appears to be an early-stage toolset with minimal documentation and unclear depth.

Target audience: security engineers, devops, backend developers
