I built a fast, private JSON toolkit that runs entirely in your browser

Two developers have launched browser-based tools prioritizing privacy. The Instant JSON Formatter allows users to process JSON data locally without server transmission, overcoming challenges with malformed strings and large payloads. Simultaneously, Interview Espresso was created for the Hacktoberfest Weekend Challenge to assist Frontend Engineer candidates. This app converts resumes and job descriptions into six-question interview rounds, utilizing a small open model to provide specific coaching on answer structure and evidence while keeping personal career data private.
