ZeroTier’s software is open source and free to use for most purposes including personal use, internal use within a business or academic institution, and evaluation for uses that require commercial licensing.
See the license terms section below for more information about which use cases do require a commercial license.
Network Controller Hosting
Creating and administrating a virtual network with ZeroTier requires a network controller. ZeroTier provides hosted network controllers with a friendly web interface, permission management, and an API via our my.zerotier.com service.
If you don’t want to use our service and have some IT expertise you can run your own network controller. A small $5 USD per month cloud node can easily run a network controller for several thousand network members.
ZeroTier software is licensed under the ZeroTier BSL, a license based on the Business Source License (BSL) version 1.1 developed by MariaDB. This license has been adopted by other commercial open source projects such as CockroachDB as an alternative to the more cumbersome and less clear GPL dual-licensing model.
The BSL works by allowing source code access and free use for all but a list of specific restricted use cases that may be defined on a per-licensed-work basis. For these use cases a separate commercial license is required. The BSL also carries an expiration date (“change date”) after which the licensed work reverts to a more permissive license of the author’s choice (Apache License 2.0 in our case). Each major release can carry an updated change date, allowing the author to extend the BSL’s coverage into the future for new releases. The existence of a change date means that should the original project’s author(s) abandon the project it will eventually fall into a more permissive open source license and can be taken over by the community.
Most uses of ZeroTier are free. We require a commercial license if you want to incorporate ZeroTier into a closed-source product, offer a for-profit service that competes with our own SaaS offerings at my.zerotier.com, or use the software in certain government or military roles.
