The short version

  • Only DuckDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: DuckDB a database file accepts one read-write process at a time; other processes must open it read-only and will not see subsequent writes, so DuckDB cannot be the shared database behind several services.; Stitch the Standard plan allows a single destination, so loading the same data into two warehouses requires the $1,500 a month Advanced plan
  • They diverge on capability: DuckDB covers In-process execution, Stitch covers Data replication.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DuckDB

  • A database file accepts one read-write process at a time; other processes must open it read-only and will not see subsequent writes, so DuckDB cannot be the shared database behind several services.
  • There is no network protocol, authentication or user management, so exposing it to remote clients means writing and securing your own service around it.
  • It is built for scans and aggregations, not for many small transactions, so a workload of high-frequency single-row inserts and updates performs badly compared with SQLite or Postgres.
  • Storage files are backwards compatible but not forwards compatible, so a file written by a newer version cannot be read by an older one and every consumer of a shared file must be upgraded together.
  • Query memory settings matter: some operations still need to hold significant state, so an under-configured memory limit turns a large join or a high-cardinality aggregation into a spill-heavy query or an out-of-memory failure rather than a slow success.

Stitch

  • The Standard plan allows a single destination, so loading the same data into two warehouses requires the $1,500 a month Advanced plan
  • The Advanced and Premium plans are billed annually only
  • The jump from Standard to Advanced is from $100 a month to $1,500
  • Standard is limited to 10 sources and 5 users
  • HIPAA support and private connectivity options such as VPN, AWS PrivateLink and VPC peering are excluded from Standard
  • Published prices are US only, with international pricing available on request

Answered from the vendors’ own pages

DuckDB: Can multiple applications share one DuckDB database?

Not for writing. One process holds the database read-write; others may attach read-only and will not see later writes. Shared multi-writer access needs a different database or a table format with a catalogue.

Stitch: How much does Stitch cost?

Stitch's usage-based pricing starts at $100/month for the Standard plan. Advanced tier is $1,500/month (annual billing), and Premium is $3,000/month (annual billing). Pricing is based on rows per month and data destinations.

DuckDB: Is it a replacement for a data warehouse?

For single-node analytical workloads up to a few hundred gigabytes it very often is. It is not a replacement when many concurrent users need a shared, governed, always-on service.

Stitch: Does Stitch offer a free trial?

Yes, Stitch provides a 14-day free trial with no credit card required.

Source
DuckDB: Do I have to load data into it?

No. It queries Parquet, CSV, JSON and Arrow in place, including on object storage. Its own storage format is optional and mainly useful when you want indexes, constraints and faster repeated access.

Stitch: How many rows can I process with each Stitch plan?

Standard plan is configurable from 5 to 300 million rows per month. Advanced includes 100 million rows per month. Premium includes 1 billion rows per month. Additional rows are available for customization.

DuckDB: What is MotherDuck's relationship to it?

MotherDuck is a separate company offering a managed and hybrid service built on the DuckDB engine. DuckDB itself remains MIT-licensed and independent of it, with the IP held by the DuckDB Foundation.

Stitch: Is Stitch pricing available outside the US?

Stitch publishes pricing for US customers only. International pricing requires contacting Stitch sales directly.

Source
DuckDB: Is it suitable for OLTP?

No. It is designed for analytical scans. For transactional workloads with frequent small writes, SQLite or Postgres is the right tool.
