What do license terms actually permit?
Read the exact license and edition, including restrictions on commercial use, redistribution and hosted services. Source-available and open source are not interchangeable labels. The OSI publishes the Open Source Definition; check each project license rather than assuming all public repositories use the same terms.
When does managed operation matter?
A library can be enough for a few fixtures owned by one development team. Shared source connections, permissions, approvals, scheduled runs and recovery may justify evaluating a platform. Confirm which features are included in the offered edition and who operates them.
How do you compare costs without guessing?
Ask each candidate for a current quote or license terms. Measure setup, maintenance, infrastructure, security review and support for the same scenario. Record the team time and assumptions; there is no universal threshold at which a commercial platform becomes cheaper.
