Frequently asked questions
Everything you need to know about privacy, extensibility, and roadmap for the mini tool showcase.
Do the tools send any data to a server?
No. Every encoder, formatter, and inspector is built to run fully in the browser so sensitive payloads stay on your device.
Can I embed these mini tools inside my product?
Yes. Components are modular, typed with TypeScript, and styled with Tailwind so you can reuse the UI or the underlying logic.
How often are new tool groups added?
We review community requests monthly and ship new collections—like generators or security helpers—once they land in beta.
