About DevKit

DevKit is a free collection of small developer tools — JSON, Base64, regex, hashes, UUIDs and more. Everything runs entirely in your browser. There is no backend, no telemetry that touches your input, and no signup.

Why another tools site?

Most online tools beg you to upload, log in, or watch a pop-up before doing the smallest thing. We wanted one place that is fast, private, and pleasant to use, with the same quality bar across every tool.
