About OnDevKit
One dev kit for everyday coding problems.
OnDevKit started with a simple idea: when you hit an error, you want the fix — not a long story. Every post starts with a quick answer, then explains why the error happens so you can stop it coming back.
What you'll find here
- Error fixes for npm, Python, Git, Windows and more, tested before we publish them.
- Free online tools — JSON formatter, Base64, regex tester and others. They run fully in your browser, so your data never leaves your device.
- AI tools and prompts — honest notes on what new tools are actually good at.
- Interview questions and cheat sheets for students and job seekers.
- Tech how-to guides written in plain language.
How we write
We test commands before we publish them, say when something is risky, and update posts when tools change. If you find a mistake, pleasetell us and we'll fix it.
