IT Tools — Collection of Developer Utilities with Beautiful UX

What it is

IT Tools is a self-hosted web application that bundles 80+ developer utilities into a single clean interface. Included tools range from UUID generators and hash calculators to JWT decoders, JSON formatters, cron expression parsers, base64 encoders, color converters, and regex testers. Everything runs in your browser with no external API calls.

The project targets developers who want a bookmark-free toolkit for common conversion and encoding tasks. Instead of searching for scattered online tools, you spin up one container and have everything on your local network.

How it saves time or tokens

Developers frequently context-switch to browser tabs for small utility tasks: decoding a JWT, formatting a JSON blob, generating a UUID. IT Tools consolidates these into one self-hosted page, eliminating the need to find and trust random online tools. Since everything runs client-side, sensitive data like API keys or tokens never leaves your machine. No signup, no ads, no tracking.

How to use

1. Start IT Tools with Docker:

docker run -d --name it-tools -p 8080:80 corentinth/it-tools:latest

1. Open http://localhost:8080 in your browser.

1. Search or browse the tool categories. All 80+ tools are available immediately.

Common pitfalls

• IT Tools runs entirely client-side; if you need server-side processing (like large file conversion), you will need a different tool
• The Docker image is relatively large because it bundles all 80+ tools; there is no way to install only a subset
• Custom tools cannot be added without forking the repository; the tool list is fixed at build time
