The short version

  • Only Parabola has a free tier, so it costs nothing to try first.
  • Each has a real cost: Parabola the Basic plan allows 1 user and 1,000 credits with limited AI; 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: Parabola covers Visual workflow builder, Stacker covers Per-record permissions.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Parabola

  • The Basic plan allows 1 user and 1,000 credits with limited AI
  • No price is published for either the self serve or the business tier
  • Credits are consumed when agents run, and further credits are bought pay as you go
  • Role based access control, SSO, version history and SLAs all sit on the unpriced business plan

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

Parabola: How much does Parabola cost?

Parabola does not publish specific pricing rates. The service uses a credit-based system where credits are consumed when agents run. Self-serve plans include a monthly credit allotment, and Business plans require a custom quote.

Source
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.

Parabola: Does Parabola offer a free plan?

Yes, Parabola offers a free tier indefinitely for self-serve users with limited credits and basic features including the Prowork agent builder and pre-built integrations.

Source
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.

Parabola: What features are included in Parabola's Business plan?

Business plans include all self-serve features plus automation engineer enablement, deployment support, proof of concept on production data, enterprise security with SSO, service level agreements, and a dedicated account manager.

Source
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.

Parabola: Can I upgrade from free to Business later?

Yes, customers can start on free or self-serve plans and upgrade to Business plans at any time.

Source
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.
