Overview

If you’re a power user, your browser likely hosts an ecosystem of extensions and pinned tabs for every small utility you need: JSON formatters, file converters, timestamp decoders, text diff tools, and more. Over time, this clutter can slow down your browser and make it harder to find what you actually need. Enter IT-Tools, a free, self-hosted collection of over 50 utilitarian web apps that can easily replace half your browser tools. This guide will walk you through setting up IT-Tools on your own machine, so you can keep everything tidy and accessible from one address.

IT-Tools runs as a Node.js or Docker application and provides tools like JSON formatting, base64 encoding/decoding, file conversion, hash generators, and many more. Instead of installing separate extensions, you just open one local site. Let’s get started.

Prerequisites

Before you begin, make sure you have the following:

Node.js (version 16 or later) and npm (or Docker if you prefer containerization)
A terminal or command line interface
Basic familiarity with running commands and navigating the file system
A machine (local or server) with at least 512 MB of RAM and 1 GB of free disk space
Port 80 or 3000 free (or you can change the port later)

If you don’t have Node.js installed, download it from nodejs.org. Docker users should have Docker Engine installed (see docs).

Step-by-Step Installation Guide

Option 1: Using npm (Node Package Manager)

Open your terminal and navigate to a directory where you want to install IT-Tools.
Install the package globally using npm:
```
npm install -g it-tools
```
Start the server:
```
it-tools start
```
By default, it runs on port 3000. You should see output like Listening on http://localhost:3000.
Open your browser and go to http://localhost:3000. You’ll see the IT-Tools dashboard with all available utilities.

Option 2: Using Docker

If you prefer to keep things isolated, Docker is the way to go.

Pull the image:
```
docker pull corentinth/it-tools
```
Run the container:
```
docker run -d --name it-tools -p 3000:80 corentinth/it-tools
```
The -p 3000:80 maps the container’s port 80 to your host’s port 3000. Change the first port if needed.
Access via http://localhost:3000.

Accessing and Using IT-Tools

Once IT-Tools is running, you’ll see a clean dashboard. You can click any tool to open it. The interface is responsive and works on mobile too. Key tools you might use daily:

JSON Formatter & Validator – paste any JSON, get beautifully indented output with validation errors highlighted.
File Converter – convert between formats like CSV, JSON, YAML, and XML.
Hash Generator – compute MD5, SHA1, SHA256, etc., from text or files.
Text Diff – compare two strings or files side by side.
Base64 Encoder/Decoder – quick conversions without leaving the page.
UUID Generator – create random UUIDs in v4, v5, or v1.

You can also bookmark the tools you use most by simply dragging the URL from the address bar to your bookmarks bar.

Customizing the Setup

To change the port: when running via npm, use PORT=8080 it-tools start. For Docker, change the first port in -p mapping. You can also run IT-Tools behind a reverse proxy (like nginx) for production use.

Common Mistakes

Port already in use. If you get an EADDRINUSE error, change the port as described above. Check which process is using the port with lsof -i :3000 (macOS/Linux) or netstat -ano | findstr :3000 (Windows).
Missing Node.js version. IT-Tools requires Node 16+. Check with node --version. If you have an older version, use a version manager like nvm to upgrade.
Docker container stops after a few seconds. Often caused by memory issues or port conflicts. Run docker logs it-tools to see error messages. Ensure the container has enough memory and the host port is not taken.
Forgetting to update. New tools are added regularly. For npm, run npm update -g it-tools. For Docker, pull the latest image and recreate the container.
Browser caching old version. If the interface looks outdated, clear your cache or use a private window to test.

Summary

IT-Tools consolidates dozens of browser utilities into a single, self-hosted application that you can access in seconds. By replacing fragmented extensions and pinned tabs, you declutter your browser, reduce resource usage, and speed up your workflow. Whether you use npm or Docker, installation takes less than five minutes. Once it’s running, you’ll wonder how you ever lived without it. Give it a try and reclaim your browser real estate.
