Support qualityNo vendor support evidence found.No support evidence reviewed
Public sentimentDevelopers praise it as a fast, secure way to ship APIs over Postgres, but warn it's not magic and weakens on complex app logic.⁷No independent user reviews were found in the sources reviewed.
Biggest gotchaMisconfigured deployments have enabled cross-tenant authorization bypasses (Capgo incident, 2026).10Shared responsibility model: misconfigured RLS policies or leaked API keys are your problem, not theirs.13
