Pricing

Pay for compute.
Not for cache hits.

Cache hits are always free. You only spend quota when Zentra has to do real work — and it caches that too.

Common questions
What counts as a query?
Any call to Zentra that reaches the AI or the database. Cache hits are always free and do not count against your quota — you only spend queries on cache misses.
What databases does Zentra support?
The free plan queries the built-in SQLite demo database so you can experience the system immediately. Pro unlocks connection to your own live PostgreSQL database with secure, read-only access.
How does caching reduce my costs?
Zentra caches the system prompt, schema definitions, and query results. Repeated queries are served from memory — zero AI tokens billed, sub-50ms response. On average teams see a 90% reduction in token costs within the first week.
What is cache warming?
Pro users can pre-load their most frequent queries into the cache. This ensures even the first query of the day returns in milliseconds rather than waiting for a cold cache miss.
How do I pay for Pro?
We accept UPI, Google Pay, credit/debit cards, and net banking via Razorpay — no special setup required.
Can I switch plans?
Yes, at any time. Upgrades take effect immediately. Downgrades take effect at your next billing cycle.
