The short version

  • Only Thunkable has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Thunkable every paid tier is metered by a monthly AI token allowance, so heavy use of the AI assistant, which is the tool's main productivity feature, can be exhausted well before a billing period ends.
  • They diverge on capability: Stacker covers Per-record permissions, Thunkable covers Block-based logic editor.
  • 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.

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.

Thunkable

  • Every paid tier is metered by a monthly AI token allowance, so heavy use of the AI assistant, which is the tool's main productivity feature, can be exhausted well before a billing period ends.
  • Only the Builder tier and above allow a live published app at all in useful numbers, so the entry-level paid plan cannot actually get an app onto the store in a meaningful way.
  • Block-based logic becomes unwieldy for apps with genuinely complex business rules, and there is no clean escape hatch to written code within the platform.
  • Native integrations and performance-sensitive features (heavy graphics, background processing) are limited compared to a coded framework, so the tool has a real complexity ceiling.
  • App ownership and export options are more restrictive than an open source framework; leaving the platform typically means rebuilding rather than exporting a portable codebase.

Answered from the vendors’ own pages

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.

Thunkable: Can I publish an app on the free plan?

The free plan is aimed at building and testing; live publishing capacity in a meaningful way starts on the Builder plan.

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.

Thunkable: What happens if I run out of AI tokens?

AI-assisted generation stops working until the next billing cycle or an upgrade; manual block-based editing still works.

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.

Thunkable: Is this suitable for a complex business app?

No. It is built for simple to moderately complex apps; heavy custom logic and native integrations are better served by a coded framework.

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.
