NLnet Labs is a not-for-profit organisation which completely relies on the support of the Internet community. All our open source software has a permissive, free software license. To ensure we remain a healthy and sustainable organisation we depend on the following types of funding.


If your organisation relies on the software we make or you want to support our activities, please consider giving a donation either as an individual or through the sponsor budget your organisation may have. A contribution can be easily paid through PayPal.

You can also support us with a monthly contribution through GitHub Sponsors for Organisations. We offer various tiers with different rewards.

If you would like to give a donation in a different way, please contact us.

Support Contracts

Being a non-profit foundation, NLnet Labs is obliged to follow strict tax regulation and not allowed to offer taxable services. As a result, we have established Open Netlabs B.V. The company is a wholly owned, taxable subsidiary of the NLnet Labs foundation serving the goals of its parent.

Open Netlabs B.V. offers support contracts with a service level for our DNS products NSD, Unbound and OpenDNSSEC, as well as our RPKI products Krill and Routinator. In addition to receiving support and early access to security patches, your financial contribution also supports our mission to provide free and open software.

Training and Software Development

If you are in need of training or software development in the area of Internet security standards such as HTTPS, DNSSEC, RPKI, DMARC, STARTTLS or DANE then we can provide these services tailored to your organisation. We can also provide you with consulting services such as installation and integration support, as well as optimisation and auditing.
