DNS Spy is built on open source and the founders have a long history with Linux and free software.
We understand the critical nature of open source projects and want help make them more secure. If you run an open source project, you can apply for a free DNS Spy account to monitor your domains.

If you currently maintain an open source project that's at least 3 months old and has its own domain name(s), reach out to us for a DNS Spy account.
You'll get a lifetime premium account (so you can use AXFR zonetransfers) to monitor all your projects' domain names for unexpected DNS changes and get a notification for each change.
