The models' case: Best overall: exceptionally broad package-manager and platform coverage, deep grouping/scheduling/versioning rules, monorepo support, lockfile maintenance, dependency. The models' main caveat: Its configuration surface is large enough to become operationally complex. The strongest alternative is Dependabot — Near-tie for typical GitHub-centric teams because setup and maintenance are extremely low-friction, security updates are tightly integrated with.
