Grafana

Grafana has a flexible pricing model that includes a perpetual free plan and paid plans that offer more capacity and support, with pricing in large enterprise plans customizable by annual commitment and usage volume. Grafana Cloud's free plan offers no-fee access to the platform, with three active users per month, community support via forums, limited data retention in some monitoring capabilities, and access to most basic monitoring services without the need for a paid subscription. Paid plans include a pay-as-you-go Pro subscription, where additional fees are charged based on the number of users, amount of data, or resources consumed, with technical support via email, longer data retention, and additional features such as Kubernetes monitoring, observability applications, API tests, and performance tests, while the Enterprise plan is ideal for large organizations, with yearly customized pricing with premium support, greater deployment flexibility, and advanced security compliance features.
