Where each one falls short

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

Appsmith

  • The free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories
  • Workflows, custom roles and audit logs all require the Business plan at $15 per user per month
  • SAML and OIDC single sign-on need Enterprise, which starts at $2,500 a month with a 100 user minimum
  • Embedding an app privately is Enterprise only; the lower tiers embed publicly
  • Managed hosting is an Enterprise add-on rather than an included option

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

Appsmith: How much does Appsmith cost?

Appsmith offers a free plan for up to 5 users, a Business plan at $15 per user per month (up to 99 users), and an Enterprise plan starting at $2,500 per month for a minimum of 100 users with unlimited users available at that rate.

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.

Appsmith: Does Appsmith have a free version?

Yes, Appsmith's Free plan provides access for up to 5 users with 5 workspaces, 3 Git repos, and community support at no cost. All plans offer unlimited apps.

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.

Appsmith: What does the Business plan include compared to Free?

The Business plan at $15 per user per month supports up to 99 users, provides unlimited workspaces and Git repos, includes workflows and reusable packages, premium integrations, custom roles, and access controls with email and chat support compared to the Free plan's community support only.

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.

Appsmith: How are Appsmith users counted for billing purposes?

Appsmith counts any user who builds or edits applications as a standard user for billing. Developers and builders are treated the same as other users and all users count toward the per-user billing model without separate developer seat charges.

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.

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.
