Yes, Prefect OSS is completely free to use with no artificial limitations imposed on: - Number of workers - Number of servers - Number of deployments - Number of flows or tasks - Workload volume Since you're already using a self-hosted server and workers via Helm charts, you're experiencing this firsthand. You can scale your infrastructure as much as needed without incurring any license fees or hitting any software-imposed caps. The only "costs" associated with Prefect OSS are the ones you're already handling: - Infrastructure costs (your own servers/kubernetes clusters) - Maintenance overhead (managing your own deployments) - Engineering time for infrastructure management This is in contrast to Prefect Cloud, which handles the infrastructure management for you but requires a subscription. But for the OSS version, you're free to use it at whatever scale you need - the only limits are the ones imposed by your own infrastructure. Worth noting that I see you're using Helm charts for deployment - that's a solid approach for managing the self-hosted components, as it gives you good control over your infrastructure scaling while keeping the management overhead reasonable.
