5 Free Developer Tools I Built for Everyday Coding

As developers, we constantly need small utilities while working.

Things like formatting JSON, generating secure passwords, testing regex patterns, or encoding data.

The problem is that most of these tools are scattered across different websites. Some require uploads, others are slow or full of ads.

So I built a small collection of browser-based developer tools that run entirely on the client side.

The goal was simple: fast tools that developers can open instantly without worrying about privacy or performance.

Here are some of the tools I use the most.

1. JSON Formatter

When working with APIs or debugging responses, JSON often becomes unreadable.

A JSON formatter helps make the structure clean and easier to debug.

Try it here:

Creating secure passwords is important but often inconvenient.

This tool generates strong random passwords instantly.

Regular expressions are powerful but tricky to debug.

A quick regex tester makes it easier to validate patterns and test matches.

Encoding and decoding Base64 strings is common when working with APIs or authentication tokens.

Sometimes you just need a quick unique identifier.

This tool generates UUIDs instantly.

I wanted a simple collection of developer utilities that:

• run entirely in the browser

• don’t upload data to servers

• load instantly

• are easy to use during development

If you use developer utilities frequently, I’d love to hear which tools you rely on the most.
