The short version

  • Each has a real cost: Cloudinary free plan includes only 25 monthly credits and is limited to 3 users and 1 account; 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.

Where each one falls short

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

Cloudinary

  • Free plan includes only 25 monthly credits and is limited to 3 users and 1 account
  • Enterprise plan pricing is custom; rates not published
  • Monthly billing is more expensive than annual; yearly plan is $89/month for Plus ($224/month for Advanced)

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

Cloudinary: What are included in Cloudinary's free plan?

Cloudinary's free plan includes upload widget, API access, search, remote fetch, auto-backup, revision tracking, image and video transformations, video transcoding, and CDN delivery. The free plan includes 25 monthly credits, 3 users, and 1 account with community support.

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.

Cloudinary: How does Cloudinary's credit system work?

Cloudinary credits measure usage: one credit equals 1,000 transformations, or 1 GB managed storage, or 1 GB image bandwidth, or 2 GB video bandwidth. The free plan grants 25 credits per month, Plus plan 225 monthly credits, and Advanced plan 600 monthly credits.

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.

Cloudinary: What is the difference between Cloudinary Plus and Advanced plans?

Plus plan costs $99/month (or $89/month annually) and includes S3 backup, auto-tagging, and expedited support for up to 3 users across 2 accounts with 225 credits. Advanced is $249/month ($224/month annually), adds custom domain (CNAME) and SSL options for 5 users across 3 accounts with 600 credits.

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.

Cloudinary: Does Cloudinary offer annual billing discounts?

Yes. Cloudinary's annual billing provides discounts: Plus plan is $89/month when billed yearly (versus $99/month monthly), and Advanced plan is $224/month when billed yearly (versus $249/month monthly).

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.
