Yes, while we are getting started — the first 250 signups get lifetime Pro for free. After that, plans are $59/year or $100 lifetime, no card required to try.

What is the difference between the Free and Pro plans?

The Free plan gives you the core developer tools at no cost. Pro adds unlimited usage, private history, saved snippets, and priority support — all still fully offline on your device.

Your data stays on your device — there is no cloud sync. Vault-style data is additionally encrypted locally with a password only you know.

Do I need an account to use the tools?

Google Sign-In is required to save your data across sessions. Many public tool pages can be explored before opening the full app experience.

Does it work offline?

Yes. MyDevTools is a desktop app — most tools run fully offline on your machine. Tools that connect to external services or send API requests need a network connection.

Does Whois Lookup store or upload my data?

Whois Lookup runs in the MyDevTools desktop app. Many utilities process data locally on your device; tools that require sync or external connections may send only the data needed for that workflow.

Do I need to install anything to use Whois Lookup?

Install MyDevTools once, then Whois Lookup and 80+ other tools are available offline on your desktop.
