DevKit does not require you to create an account, provide an email address, or authenticate in any way. You can use all tools immediately.
DevKit does not use a database. There is no server-side storage of any user data. Your tool inputs, outputs, and preferences are never stored on our servers.
The vast majority of tools run entirely in your browser. JSON formatting, Base64 encoding, hashing, UUID generation, regex testing, and many other operations happen locally on your device. Your data never leaves your machine.
Tools that process data locally are marked with a lock icon and the label "Runs entirely in your browser."
A small number of tools may require network access for functionality that cannot be replicated locally. These tools are clearly identified with a globe icon and the label "Requires network access."
DevKit uses browser localStorage to remember your preferences:
We never store sensitive input data such as passwords, API keys, JWTs, or private keys in browser storage.
DevKit does not include third-party analytics, advertising, or tracking scripts.
