The short version

  • Only Polytomic has a free tier, so it costs nothing to try first.
  • Each has a real cost: Polytomic pricing begins at $500 a month on the Standard 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.
  • They diverge on capability: Polytomic covers No-code syncing, 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.

Polytomic

  • Pricing begins at $500 a month on the Standard plan
  • Neither plan publishes a full rate, sync limit or row allowance, and both direct buyers to book a call
  • SSO, on premise deployment and phone support are Enterprise only

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

Polytomic: What is Polytomic's minimum monthly cost?

Polytomic Standard tier starts at $500/month for sync capabilities across databases, warehouses, spreadsheets, apps, and APIs with live chat support. Custom pricing available for Enterprise tier. Source: https://www.polytomic.com/pricing

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.

Polytomic: Does Polytomic offer on-premises deployment?

Yes. On-premises deployment is available on the Enterprise plan with custom pricing. Includes SSO, dedicated engineer support, and phone support. Source: https://www.polytomic.com/pricing

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.

Polytomic: What support does Polytomic Standard tier include?

Polytomic Standard tier ($500/month) includes live chat support for data synchronization questions. Enterprise tier upgrades to dedicated engineer support and phone support. Source: https://www.polytomic.com/pricing

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.

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.
