Every calculator, converter, and developer tool computes results in Node.js on your machine. Nothing is transmitted to allio Tools or any server.

🚫

No API keys

Add one line to your config file and it works. No accounts, no registration, no tokens to manage.

📖

Open source

Every line of code is public. Read it, audit it, fork it. No hidden behaviour.

🌐

Network tools disclosed

DNS lookup, site status, and similar tools make direct calls from your machine to their target. These are clearly labelled.
