As a developer, I constantly found myself switching between multiple websites for simple tasks like formatting JSON, generating passwords, or converting text cases.
So I built DeveloperToolsKit — a collection of over 35 free online tools made specifically for developers.

What is DeveloperToolsKit?
DeveloperToolsKit is a free, browser-based toolbox that includes all the essential developer utilities — without registration, without ads, and without tracking.

You can:

Format and minify JSON

Convert text to camelCase, snake_case, kebab-case, etc.

Generate hashes (MD5, SHA-1, SHA-256)

Create secure passwords

Build color palettes

View and analyze CSV files

Generate QR codes

Find your IP address
And more…

Why I built this:
I was tired of using bloated, slow or ad-filled websites just to complete basic tasks.
DeveloperToolsKit was built with speed, simplicity and privacy in mind. Everything works right in your browser — no data ever leaves your device.

Who is it for?
Whether you're a frontend or backend developer, DevOps engineer, coding student, or just someone who needs small utilities every day, DeveloperToolsKit can help streamline your workflow.
