Free developer tools, right in your browser
Codeutil is a collection of free, fast, and privacy-friendly online tools built for developers, engineers, and anyone who works with code and data.
We believe that everyday developer utilities should be instant, ad-light, and require zero sign-ups. That’s why every tool on Codeutil runs entirely in your browser — no data is ever sent to a server, no accounts are needed, and everything is completely free.
What we offer
Codeutil provides a growing library of tools across several categories:
- JSON tools — Format, validate, minify, compare, and convert JSON data
- Code formatters — Beautify HTML, CSS, JavaScript, SQL, and more
- Encoders & decoders — Base64, URL encoding, HTML entities, and hashing utilities
- Generators — UUIDs, Lorem Ipsum, passwords, and other useful outputs
- Converters — Transform data between formats like YAML, XML, CSV, and Markdown
- Reference guides — Quick-access cheat sheets for Git, Docker, Linux, and web standards
New tools are added regularly based on what developers actually need.
Our principles
Privacy first — Every tool processes data locally in your browser. Your code, your JSON, your data never leaves your device.
Speed matters — No bloated frameworks or slow page loads. Tools are lightweight and ready the moment you open the page.
Free forever — Codeutil is supported by non-intrusive advertising. We will never charge for access or lock features behind a paywall.
Developer-friendly — Built by developers, for developers. Clean interfaces, keyboard shortcuts, and no unnecessary friction.
