About deviloper.dev

What this is

deviloper.dev is where I put the things I build in my spare time. I’m Yogesh Joshi, a software engineer, and I like making small, focused apps that do one job well. Some are practical, like a ruler you can hold objects up against or a counter for checking whether a post fits a platform’s limit. Others are just for fun or curiosity, like a game to fill a short break or a simulation to watch.

Each app lives on its own subdomain. This site is the catalog that ties them together, with a page for each app explaining what it does and how to use it.

How the apps are built

The apps are deliberately lightweight. They run in your browser, so there is nothing to install and no account to create. Where an app works with something you type or measure, that work happens on your device. I try to keep each one fast, simple to understand and usable on the devices it makes sense for.

How it's funded

Everything here is free to use. Ads served by Google AdSense help cover the costs and keep it that way. You can read how ads, cookies and your consent choices work in the privacy policy.

New apps

The collection grows as I finish things. When a new app launches, it’s added to the catalog with its own page, so the home page is the best place to see what’s new.
