IT-Tools: Self-Hosted Developer Utility Toolkit with 70+ Tools

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.

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.

Frequently Asked Questions

What is IT-Tools and why self-host it?

IT-Tools is a web application bundling 70+ developer utilities in one interface. Instead of googling for online base64 decoders, JWT debuggers, or CIDR calculators, you access them all from a single self-hosted page. Your data stays local — critical when dealing with tokens, API keys, or encoded credentials.

What categories of tools are included?

Crypto (hash generators, UUID, ULID, password generator), converters (base64, hex, binary, YAML/JSON/TOML), web (JWT decoder, URL encoder, HTML entities), network (CIDR calculator, IPv4 subnet, MAC lookup), text (Lorem ipsum, word counter, regex tester), and many more.

Can I add custom tools?

IT-Tools is open source (Vue.js). You can fork the repo and add custom tools. The community also contributes new tools regularly.

Does it require any backend or database?

No. IT-Tools is a pure frontend application — everything runs in the browser. The Docker container just serves the static files. No database, no API keys, no external dependencies.
