I got tired of opening random online tools that either track everything or send my data to some server just to format JSON or check if a model fits on my GPU.
So I built UsefulAtlas — a collection of browser-based developer tools and AI hardware calculators that run fully client-side where possible.
What it currently has
Coder Box
JSON formatter/minifier, Base64, UUID generator, hash tools, JWT inspector, text cleaner — all local in the browser.
