Both! We offer both versions of Cortex and our self hosted version is at feature parity with cloud. The self hosted version is an easy to deploy helm chart. You can also start one and move to the other at any point.
You can try Cortex for free for two weeks and we will help support your team as they navigate the platform.
All customers of Cortex get a shared Slack channel and we pride ourselves on our responsiveness. We also deeply value customer feedback and prioritize your requests in our roadmap.
