Neon - Pros & Cons
Pros
- ✓Cheapest idle posture of any managed Postgres — pay only when queries run

- ✓Backed by Databricks since 2025, easing long-term viability concerns
Cons
- ✗Cold starts in the hundreds of milliseconds matter for latency-sensitive paths

Arcade AI - Pros & Cons

- ✓Transparent pricing with a usable free Hobby tier and published Growth usage allowances
- ✓Strong fit for developers building agents that must safely act in SaaS tools
Cons
- ✗Developer infrastructure product; non-technical teams will need engineering support to implement it well
