The short version

  • 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.; Superblocks teams plan is limited to just 1 hosted app by default, with additional apps costing $10/app/month.
  • They diverge on capability: Stacker covers Per-record permissions, Superblocks covers Clark AI agent.
  • 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.

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.

Superblocks

  • Teams plan is limited to just 1 hosted app by default, with additional apps costing $10/app/month.
  • Usage is capped by Governed Agent Units, adding a metering layer beyond a flat per-seat price.
  • Advanced deployment options like VPC and Cloud-Prem are reserved for the custom-priced Enterprise tier.
  • No published free tier, only a 14-day trial, making it harder to evaluate at no cost long-term.

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.

Superblocks: What does Superblocks cost?

The Teams plan costs $125/month billed monthly or about $100/month billed annually, including 100 Governed Agent Units and up to 15 builders; Enterprise pricing requires booking a demo.

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.

Superblocks: Is there a free plan?

Superblocks does not offer a free ongoing plan but provides a free 14-day trial of the Teams plan.

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.

Superblocks: Who owns the code Superblocks generates?

Superblocks states that users fully own all code generated on the platform and can connect it to their own git repository.

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.

Superblocks: What deployment options does Superblocks offer?

Superblocks supports Cloud, Hybrid (production data kept in the customer's VPC), and Cloud-Prem (the full platform run inside the customer's environment) deployment models.
