NLnet Labs

Proudly serving the Internet community since 1999 with core infrastructure tools for DNS and BGP.

💚 Hello from NLnet Labs!

Founded in 1999, NLnet Labs is an independent, non-profit foundation based in the Netherlands. Our mission is to make the core of the Internet a better, safer place by developing open-source software, through applied research and by promoting and contributing to open standards.

🌱 Sustainable Open-Source

We believe in sustainable open-source software. NLnet Labs is not owned by a commercial organisation. We operate independently with 16 full-time developers and researchers on staff. We are funded by organisations who rely on our software and by those who think our work is important.

🤝 Our Commitment to You

  • Our software is, and always will be, open-source with a liberal license
  • We will have at least two developers on each of our projects
  • You will always get all features for free, we will never adopt a "freemium" model
  • We will only develop functionality that serves the general benefit of the Internet community
  • Because our software is used in mission critical environments, we offer support services with a service-level agreement
  • We guarantee continued maintenance of our software for at least two years in the unlikely event all funding would disappear

🫶 Support our Work

We cannot do any of our work without your support. If you depend on our software, please consider purchasing professional support and consultancy services with a service-level agreement for one of our products, sponsoring the development of new software or a feature for an existing product, or through a donation.

🌈 A Vibrant Community

At NLnet Labs, we are committed to an open mindset that encourages anyone to contribute to our software and discussions on Internet technology. To exchange ideas you can use our Discourse community forum, find us on Mastodon or use one of our mailing lists.

You are likely to run into one of us in real-life at industry events such as IETF or ICANN meetings, or at operator meetings such as RIPE or DNS-OARC. We'd love to discuss ideas and hear your feedback!
