Support quality	Community-driven; frequent releases, no vendor SLA	Vendor claims engaged support; thin independent evidence
Public sentiment	Engineers praise its speed and simplicity, but some report slow results when their workload doesn't fit its single-node design.^⁴	Users love the simplicity and sharing, but grumble about the 2026 price hike and whether it belongs in production.
