TL;DR — Quick Summary

Deploy IT-Tools self-hosted: 70+ developer utilities for encoding, hashing, JWT debugging, CIDR calculations, UUID generation, and data conversion.

Why IT-Tools?

Developers constantly need small utilities: decode a base64 string, debug a JWT, calculate a subnet mask. Online tools work but your data travels through someone else’s server. IT-Tools keeps it local:

  • 70+ tools in one interface.
  • Pure client-side — data never leaves your browser.
  • No accounts or API keys — open and use.
  • Search — find any tool instantly.
  • 2-minute deploy — one Docker command.

Prerequisites

  • Docker on any machine.
  • Minimal resources (static files only).

Deploy with Docker

docker run -d \
  --name it-tools \
  --restart=always \
  -p 8080:80 \
  corentinth/it-tools:latest

Access at http://your-server:8080. That’s it.

Troubleshooting

Problem Solution
Page loads but tools don’t work Clear browser cache; ensure JavaScript is enabled
Can’t access from other machines Verify Docker port mapping and firewall open on port 8080
Want to update docker pull corentinth/it-tools:latest then recreate container

Summary

  • One Docker command for 70+ developer utilities.
  • Client-side only — no data leaves your browser.
  • Role-based value — useful for developers, DevOps, sysadmins, and security teams.
