I got tired of bookmarking 50 different utility sites, so I built one with 100+ Free Tools 🥷

We’ve all been there. You are in the middle of coding, and you quickly need to format a messy JSON file, encode a URL, or compress a quick image.

So, what do you do? You Google it.
And you land on a website that takes 10 seconds to load, throws 3 popup ads in your face, and asks you to create an account just to download your file. 🤦‍♂️

I got incredibly frustrated with this cycle of bookmarking dozens of different, clunky utility websites. I just wanted a clean, fast, and simple place to get things done without the nonsense.

So, I decided to build it myself.

Meet ToolsNinja — A unified collection of 100+ free, blazing-fast developer utilities and web tools. 🚀

✨ What makes it different?

When building ToolsNinja, I focused on developer experience (DX).

Zero Paywalls & No Signups: You don't need an account to use anything.
Blazing Fast: Built to load instantly. No heavy bloatware.
Dark Mode Native: Because we developers live in the dark. 🌙
Mobile-Friendly: Works perfectly on your phone if you need a quick tool on the go.

I’ve categorized the tools so they are easy to find. Here are a few things you can do right now:

💻 For Developers:

I am actively maintaining and adding new tools to the platform. Since this was built to solve my own itch, I’d love to hear from other developers.

What is that ONE utility tool you use every day that I should add to ToolsNinja?

Let me know in the comments! Feedback and roasts are highly appreciated. 🙏
