Pricing

TDB is an open-core product. The community edition is free, forever. Paid tiers add the connectors, auth, and compliance features you need to run TDB in production for a real team.

Pricing is published transparently. No "contact sales for pricing."

The open-source guarantee

Features in the community edition are free forever under AGPLv3. We will never move a free feature behind a paywall. If you evaluate TDB today with CSV, those capabilities are yours permanently — no license change, no feature flag.

FAQ

Can I run the enterprise tier on-premises? Yes. TDB is self-hosted by design. The commercial license covers your on-premises deployment. There is no SaaS-only restriction.

What happens when my trial ends? We don't run time-limited trials. Email us and we'll arrange a 30-day evaluation licence at no charge.

Do you offer volume discounts beyond the 15% annual? Yes, for deployments with more than 10 seats or custom support requirements. Get in touch.

Is the source code for the enterprise tier available? No. The enterprise tier is a closed-source commercial product. The community edition is fully open under AGPLv3.

I need BigQuery / Datadog / SSO now. When do those ship? Target Q3 2026. If these are blocking your evaluation, email us — design partner conversations accelerate the roadmap.
