DevUtilX's answer
Every developer knows the struggle: Youโre in the middle of coding, and suddenly you need a quick JSON formatter, a CSS gradient generator, or a way to validate an API response. You Google it, land on a cluttered site, use the tool once, and then repeat the cycle tomorrow with another tool.
That frustration was the seed for DevUtilX.
The idea was simple: what if all these everyday developer tools lived in one clean, reliable place? A place that didnโt force sign-ups, didnโt send your code to unknown servers, and didnโt make you click through pop-ups just to copy your output.
So DevUtilX was born โ a Swiss Army knife for developers. Instead of 20 scattered bookmarks, you get 100+ free tools under one roof: formatters, validators, converters, generators, CSS helpers, image utilities, and more. Each tool works instantly in your browser, powered client-side for speed, privacy, and simplicity.
What started as a small personal project has now grown into a platform used by developers, students, and freelancers around the world. And the journey isnโt done โ with community feedback, new tools keep getting added to make DevUtilX even more powerful.

In 2021, my workflow involved frequent JSON manipulation: debugging API responses, integrating with third-party services, and inspecting data structures. Like many developers, I defaulted to googling "JSON prettier" and using whatever website appeared first. Tools like JSON Formatter and JSON Pretty Print worked fine, but they came with a cost: ads everywhere, no transparency about data handling, and zero... - Source: dev.to / 6 months ago
And when I'm working with those JSON files and they're broken (happens all the time), this JSON Formatter fixes them quick. No more looking for missing commas forever. - Source: dev.to / about 1 year ago
**Note:* Online Post request should have the correct format to ensure that requested data will be created. It is a good practice to use Get first to check the JSON format of the request. You can use tools like https://jsonformatter.curiousconcept.com/. - Source: dev.to / over 1 year ago
This can look like this, for example. Postman shows you errors in the JSON structure directly. However, you can test it more precisely with this JSON validator. - Source: dev.to / about 2 years ago
