Stacker
Permissioned portals over data that stays in Airtable, Salesforce or Postgres
As of 31 August 2026, Stacker's pricing is not published; the vendor quotes on request. A portal builder that puts a permissioned interface in front of a database you already have, rather than storing the data itself. Softwr lists it under No-Code. Stacker is available on Web.
Overview
What Stacker does
Stacker builds web portals and internal applications on top of an existing data source: Airtable, Google Sheets, Salesforce, HubSpot or a Postgres database. You connect the source, define which records and fields each user or role may see and edit, and lay out list, detail and form pages. Authentication, per-record permissions and invitations for external users are the parts it does that would otherwise be a custom build. The answer to what you own when you leave is unusually clean, and it is the reason to consider it. Stacker never becomes the system of record, so the data stays where it already was and cancelling costs you the interface rather than the information. Set against that, there is no source export at all and no self-hosting, and the application logic lives entirely in Stacker configuration. The rebuild cost on exit is therefore the front end and the permission model, which for a portal with many roles is not trivial. The permission engine is the actual product here, and it is precisely the thing you cannot take with you. Buyers are operations teams giving clients, partners or contractors a controlled view of an internal Airtable or Salesforce base, and small businesses that need a portal without a development team. The binding constraint is the source system underneath: Stacker inherits its rate limits, record limits and field types, so an Airtable base near its row ceiling produces a slow portal, and the fix is migrating the source rather than tuning the portal.
What people use it for
- Giving clients a login that shows only their own records inside an internal Airtable base
- Contractor or franchisee portals where each account must see one slice of a shared dataset
- Replacing a spreadsheet emailed to partners with a permissioned live view of the same data
- Putting a usable interface on a Salesforce or Postgres dataset for users who should never see the underlying system

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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, with sources
Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
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.
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.
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.
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.
