Any instance size is available to any user, from day one.

Read replicas

Add read capacity at 60% of the primary compute cost.

Inference included

Write-time inference runs automatically. No extra charge per rule.

Common questions.

How does compute billing work?

Billed per hour while your instance is running. Stop it anytime to pause billing. Storage charges continue while data is retained.

What counts as a write query?

Anything that adds data or changes the schema — ingesting sources, updating records, applying schema changes. Reads (questions, API reads, GraphQL, introspection) bill at the lower read rate.

Can I resize without downtime?

Vertical resize (changing instance size) takes ~30 seconds. Adding read replicas has zero downtime.

What's included in the free tier?

One XS instance (2 GB RAM, 1 CPU), unlimited queries, and 10 GB storage. No credit card required.

Do the managed and control tiers cost different amounts?

No. They're the same engine on the same instance — the control tier just exposes deeper settings (schema editing, retrieval tuning) when you want them. You pay for the instance, not for the depth.

Do you offer academic or nonprofit discounts?

Yes. Contact us for special pricing for academic institutions, nonprofits, and open-source projects.
