About DevToolkit
DevToolkit is a free collection of fast, simple and privacy-conscious tools designed to make everyday developer tasks easier.
Every developer has a shortlist of tiny utilities they reach for constantly: formatting a blob of JSON, decoding a JWT, generating a UUID, testing a regex. DevToolkit brings twenty of those utilities together in one fast, distraction-free place.
The project is focused on useful, everyday utilities rather than trying to be everything at once. Each tool is built to do one job well, with sensible defaults, clear error messages and no unnecessary friction between you and the result you need.
Wherever a task can be done entirely on your device, it is — most tools run only in your browser and never send your input to a server. That means faster results and fewer reasons to worry about what happens to the data you paste in.
DevToolkit has no accounts, no paywalls and no dark patterns. It is, and will remain, free to use for the tools available today.
