I built 59 free browser-based dev tools in vanilla JS — here's what I learned

Two developers have launched specialized tools for the tech community. The first created RepoAudit, a REST API that audits public GitHub repositories to provide data quality reports and AI-powered complexity scores for issues, solving manual triage problems. Simultaneously, another developer released Antigravity Tools, a collection of 59 free browser-based utilities built with vanilla JS. These tools prioritize privacy by using native APIs like Web Crypto API, ensuring all operations run locally without servers or telemetry.
