As a web developer, I often found myself opening multiple websites just to handle small but frequent tasks formatting JSON, decoding JWTs, generating CSS gradients, or compressing images, generating diagrams.
Each tool worked, but the experience was rarely smooth. Too many ads, cluttered UIs, or unnecessary sign-ups disrupted my workflow.
So I decided to build something simple for myself.
The Problem I Wanted to Fix
Developers deal with dozens of micro-tasks every day:
👉 Formatting or comparing JSON
👉 Decoding tokens while debugging
👉 Converting images or Base64
👉 Creating gradients or flow diagrams
👉 Count bytes to MB or GB
None of these should require jumping between multiple slow websites.
What I Built: CodeUtils
CodeUtils is a free, browser-based developer toolbox designed for speed and simplicity.
- No sign-up
- Clean, distraction-free UI
- Fast, local-first tools
It started as a personal project, but I realized many developers face the same daily friction.
A Few Tools Inside CodeUtils
Instead of listing everything, here are some commonly used tools:
- JSON Formatter & Diff – Format and compare JSON instantly
- JWT Decoder – Decode tokens without server calls
- CSS Gradient Generator – Create clean gradients quickly
- Mind Map & Flowchart Generators – Plan logic visually
- Image Compressor – Reduce the project size
In total, CodeUtils currently offers 22+ focused developer tools, all accessible from one place.
Writing About the “Why”
I’ve also started documenting ideas and use cases in the CodeUtils blog, including:
- Essential Developer Utilities – why small tools matter
- Mind Map Generator – using visual thinking to improve code structure
The goal is not just to provide tools, but to explain how developers can use them effectively.
What’s Next?
CodeUtils is still evolving-improving UI, adding practical tools, and writing more developer-focused content.
