Editions

TDB is an open-core product. The community edition is free, forever under AGPLv3. The paid editions add the connectors, auth, and compliance features you need to run TDB in production for a real team.

This page shows exactly what each edition includes. For pricing and a free 30-day evaluation, email us — we'll tailor a quote to your deployment and get you set up.

† All editions currently cap responses at 1,000 rows — a deliberate safety default that keeps an AI agent from pulling an entire table. Push work down with aggregates and named views; pagination beyond 1,000 rows is on the roadmap.

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.

How do evaluations work, and what happens when mine ends? Email us and we'll issue a 30-day evaluation licence at no charge — a dedicated, self-hosted image with the licence baked in, running entirely on your own infrastructure (no data reaches us). When it expires, TDB keeps running and /health stays healthy, but data and API requests return a clear license_expired response until you renew or convert. Need longer to evaluate? Just ask.

Do you offer annual or volume discounts? Yes — annual subscriptions and larger / multi-seat deployments qualify for discounts. Email us to discuss terms.

How much does it cost? Paid editions are a flat self-hosted license (no per-query or per-row metering). We share pricing by email so we can match the right edition to your deployment and include a free 30-day evaluation — 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.
