The license is free, but operational costs (hosting, maintenance, patching, upgrades) replace the vendor's license fee. Teams without dedicated ops resources often spend more on self-managed open source than they would on a managed commercial alternative.
Open source is strongest when you need full code control, on-premises deployment for compliance, or want to avoid vendor lock-in. It's weaker when your team lacks the ops capacity to maintain, patch, and scale the deployment.
Evaluate community activity (commits, issues, releases in the last 6 months), commercial support options, documentation quality, and the total operational burden vs a managed alternative. A dormant project with no commercial backing is a risk.
