The short version

  • Each has a real cost: Caspio data record limits are hard caps (1.25 million on Team, 4 million on Business), so a fast-growing dataset can force an upgrade even with the same small internal team using it.; Stacker there is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
  • They diverge on capability: Caspio covers Visual app builder, Stacker covers Per-record permissions.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Caspio

  • Data record limits are hard caps (1.25 million on Team, 4 million on Business), so a fast-growing dataset can force an upgrade even with the same small internal team using it.
  • DataPage counts (100 on Team, 200 on Business) limit how many distinct app components can be built, which becomes a real constraint for an organisation running many small, separate apps rather than a few large ones.
  • The HIPAA compliance add-on costs 500 US dollars a month on top of the base plan with a one-year minimum term, a meaningful additional commitment for healthcare-adjacent buyers.
  • Its unlimited-user model is only cheaper than per-seat competitors when the user count is genuinely high relative to data volume; a small team with heavy data needs may find a per-seat platform cheaper.
  • The visual builder and DataPages approach is less suited to complex multi-step business process automation than platforms built around workflow engines, such as Appian or Mendix.

Stacker

  • There is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
  • Performance is bounded by the data source, so an Airtable base near its row limit or an API under rate limiting produces a slow portal that no amount of Stacker configuration will fix.
  • Pricing distinguishes internal editors from external portal users, so a portal that succeeds by adding hundreds of light-touch external users can end up costing more than the internal system it fronts.
  • Custom logic is limited to the actions and conditions the builder exposes, so anything resembling a calculation engine or a branching multi-step approval hits a wall and needs an external automation tool bolted on.
  • It is a portal and CRUD tool by design, with no offline mode, no native mobile application and no real reporting layer, so it will not be the only system a growing operation runs.

Answered from the vendors’ own pages

Caspio: Does Caspio charge per user?

No. Every published tier includes unlimited users; the price scales with data record volume and DataPage count instead.

Stacker: Where does my data live?

In the source you connect: Airtable, Salesforce, HubSpot, Google Sheets or your own Postgres. Stacker reads and writes to it rather than becoming the system of record.

Caspio: What is a DataPage?

An individually configured, embeddable app component, such as a form or report, that can be placed inside an existing website.

Stacker: Can I export the app if I cancel?

No. The data stays in your source system, but the interface, permissions and workflows are Stacker configuration and do not come with you.

Caspio: Is HIPAA compliance included?

No, it is a separate add-on priced at 500 US dollars a month with a minimum one-year term.

Stacker: Is it suitable for hundreds of external users?

Technically yes; check the pricing arithmetic first, because external portal users are charged separately and that is where the bill grows.

Stacker: Will it replace Airtable?

No, it sits in front of Airtable. If the base itself is at its limits, the fix is moving the data to Postgres rather than changing the portal.
