The Netdata Agent is free, open source software licensed under GPL v3.0. No registration is required; just install and go. It is ideal for single-node monitoring.
Netdata Cloud is free, closed source, software-as-a-service that brings together metadata from all of your endpoints running the Netdata Agent, giving you a complete view of the health and performance of your infrastructure.
Because you retain all of your data, Netdata Cloud is extremely lightweight and performant, with very low incremental cost and infinite scalability.
In the future, we will offer a paid plan with advanced functionality for enterprise users.
