|---|---|---|
| Verdict | Depends | Depends |
| Best for | Apps outgrowing a single database node | Developer teams wanting Postgres plus auth, APIs, and storage |
| Who it's not for | Small apps on a single database node | Non-technical teams wanting a no-code database |
| Privacy | No known public vulnerabilities found in the sources reviewed.12 | Strong on paper: SOC 2 Type 2, ISO 27001, HIPAA (with BAA), AES-256 at rest, TLS in transit, regular pen tests.13 |
| Support quality | No support evidence in sources | No support evidence reviewed |
| Public sentiment | Reviewers praise the developer experience and zero-downtime migration tooling, noting it shines mainly at scale.¹ | No independent user reviews were found in the sources reviewed. |
| Biggest gotcha | $5 entry covers single-node Postgres; sharded Vitess/Neki pricing not shown publicly⁷ | Shared responsibility model: misconfigured RLS policies or leaked API keys are your problem, not theirs.13 |
