The models' case: Best overall for most small teams: automatic JavaScript monorepo discovery, per-package services and watch paths, Dockerfile support, private networking, preview. The models' main caveat: Usage billing can become less predictable for steady, resource-heavy workloads, and production collaboration requires Pro. The strongest alternative is Render — The strongest production-oriented default: precise monorepo root directories and build filters, reliable zero-downtime Docker deploys.
