Vanna
Vanna is an open-source SQL-agent framework with a managed cloud option that connects multiple databases and works with any language model provider. It exposes admin features in hosted plans and enforces daily question limits on paid tiers while allowing self-hosted deployment.
Explorer $50 per month and Team $500 per month plans are documented with daily question limits; Enterprise is custom (contact sales). Annual subscriptions receive a 20% discount when billed annually.Is Vanna right for you?
Good for
- Data teams that want a multi-database natural-language SQL agent framework that lets you switch language model providers and choose hosted or self-hosted deployments without vendor model lock-in.
- Open-source framework that you can self-host or upgrade to managed cloud.
- Works with any language model provider and multiple databases so you can pick your model and data stack.
Keep in mind
- Plans enforce daily question throughput limits and requests are rate-limited when limits are exceeded.
- Buyers who require detailed published API request-per-second or throughput metrics for high concurrency; the site lists daily question limits but not low-level rate specs—confirm throughput needs.
Pricing and plan limits
linked official pages list Explorer and Team monthly prices and Enterprise as custom; they explicitly state annual subscriptions receive a 20% discount. The linked official pages do not itemize per-request API rate units beyond questions/day.
