What is D4N Tools?

A growing library of browser-based utilities: DNS records, password generation, JSON formatting, quick polls, and more. Everything runs in your browser, with no account required.

Our principles

• Privacy first. Most tools run entirely in your browser. The few with a backend (such as Straw Poll) store the minimum needed to work, tied to no identity.
• No friction. No sign-up, no ads, no paywalls. Open the tool, use it, done.
• Fast and reliable. Served from a global CDN, so pages load quickly wherever you are.

Privacy key

Every tool displays a privacy marker. Full detail in the privacy policy.

• Your device Runs entirely in your browser. Nothing is sent anywhere.
• 3rd-party API Sends your query to an external service (such as a DNS resolver). D4N Tools stores nothing.
• D4N cloud Stores the minimum needed to work, such as a poll and its votes. Nothing is tied to your identity.
