DuckDB plans and pricing
Open Source
This plan is ideal for all users, from individual developers to large enterprises, seeking a powerful, in-process analytical database
DuckDB pricing: the quick answer
DuckDB is free as of July 8, 2026. It ships under the MIT license as a single open-source build with no paid tiers, no subscription, and no per-seat cost. You embed it in-process inside Python, R, or any application and query Parquet, CSV, and JSON directly, including files on S3, without standing up a server. The one caveat is that DuckDB is an analytical engine, not a multi-user transactional database, so it does not handle concurrent writes the way Postgres or MySQL do. A managed cloud version, MotherDuck, exists as a separate service with its own pricing that DuckDB does not set.

DuckDB is free to start, against a $82.76/mo median across 6 databases tools we track.

Positioning
DuckDB is free under the MIT license, and that is the whole pricing story. There is one build, no feature-gated tiers, and no subscription. You get vectorized execution and direct querying of Parquet, CSV, and JSON, including files on S3, without running a server. For a team analyzing datasets under a terabyte, it removes the need for a cloud data warehouse entirely, which is a rare thing to say about a database.
Cost drivers
- 1None from DuckDB itself. There are no overage charges, add-ons, or license fees. The only real cost is the compute you run it on, which is whatever laptop or VM you already have.
- 2A managed cloud option, MotherDuck, exists as a separate paid service with its own pricing. That is a different product, not a DuckDB tier.
Watch-outs
The common mistake is reaching for DuckDB as a general-purpose database. It runs in-process and is built for analytics, so it does not serve concurrent writes or act as a shared multi-user production store.
Strengths
- Runs in-process with zero infrastructure setup
- Queries Parquet and CSV on S3 directly, no ETL
- Beats many server-based databases on single-machine workloads
Editor’s take
Data scientists, analysts, and startups running analytical workloads under a terabyte should just use it; there is nothing to buy and nothing to negotiate. If you actually need a multi-user transactional database rather than a local analytical engine, PostgreSQL is the open-source engine to reach for instead.
