The short version

  • Each has a real cost: Budibase cloud plans are metered on automation actions, from 5,000 a month on Pro to 250,000 on Business; 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.
  • They diverge on capability: Budibase covers Drag-and-drop builder, DuckDB covers In-process execution.
  • 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.

Budibase

  • Cloud plans are metered on automation actions, from 5,000 a month on Pro to 250,000 on Business
  • Creator seats are limited and cost $50 each beyond the included count
  • End users are $5 per user per month on top of the plan
  • Custom branding needs Premium, SSO enforcement and environment variables need Business, and audit logs are Enterprise only
  • Log retention is tiered from 1 day on Pro to 365 days on Enterprise
  • Monthly billing costs 20 percent more than annual

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.

Answered from the vendors’ own pages

Budibase: What happens if I exceed the monthly action limit on my plan?

Actions are hard monthly limits. Once you reach the limit on your plan (5K for Pro, 20K for Premium, 250K for Business), you must upgrade to a higher tier to continue using the service.

Source
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.

Budibase: Is there a charge for additional users beyond what is included in my plan?

Yes. Each plan includes a limited number of creators (1 for Pro, expandable for Premium, 3 for Business), but end users are charged at $5 per user per month as an add-on.

Source
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.

Budibase: How much extra do I pay if I choose monthly billing instead of yearly?

Monthly billing costs 20% more than the yearly equivalent. For example, paying monthly for Pro at $19/month equals $228 per year, versus $190 per year on a yearly subscription.

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.

Budibase: Can I try Budibase before committing to a paid plan?

Yes. All paid cloud plans include a 14-day free trial. The open source version is also available free with unlimited actions and unlimited users, though with community support only.

Source
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.

Budibase: Does the free open source plan include the same features as paid plans?

The open source plan includes unlimited actions, unlimited apps, automations, agents, and users, but support is community-only rather than through Budibase directly. Paid plans add features like AI credits, custom branding, backups, and email or priority support.

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.
