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

Developers are launching free, browser-based utility collections to enhance privacy and efficiency. Antigravity Tools offers 59 utilities built with vanilla JS, utilizing native APIs like Web Crypto and IndexedDB to ensure zero server dependencies or telemetry. Similarly, PureDevUtils provides 16 tools for tasks like JSON formatting and JWT decoding without uploading sensitive data. Additionally, Stefan, a TYPO3 developer, has introduced his own page of free browser tools to assist the developer community.
