We're excited to announce SelfDevKit - an all-in-one desktop toolkit for developers with 50+ essential tools. Work offline, keep your data private, and boost your productivity without the browser tab chaos.
SelfDevKit is designed to work completely offline. All tools and features are available without an internet connection, ensuring you can work anywhere, anytime. Your data stays on your machine, giving you complete control and privacy.
From JSON formatting to JWT debugging, file generation to regex testing - SelfDevKit includes everything you need in one place. No more switching between browser tabs or installing multiple tools.
Your data never leaves your machine. We believe in privacy-first development, which is why all tools process data locally. The only time we connect to our servers is during license activation.
