Before you commit
Verify your team has DevOps skills for deployment and ongoing maintenance before choosing any option. Check hardware requirements, security update cadence, and community support activity. Confirm there are no hidden paid tiers for advanced features or enterprise support. Test self-hosting on a small scale first to surface integration or scaling limits.
