Permissioned portals over data that stays in Airtable, Salesforce or Postgres

- -
The short version
- Only Nintex has a free tier, so it costs nothing to try first.
- Each has a real cost: Nintex no published pricing on website; requires direct sales contact; 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: Nintex covers 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.
Nintex
- No published pricing on website; requires direct sales contact
- Free trials available but no trial duration specified
- Multiple product lines (Cloud, K2, Salesforce) complicate pricing assessment
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
Nintex: Is Nintex free?
Nintex offers 30-day free trials for Workflow and Apps, plus free trials for Process Manager, eSign, and DocGen. No permanent free tier is advertised on their website.
SourceStacker: 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.
Nintex: What is Nintex pricing?
Nintex does not publish pricing on their public website. Pricing varies by product (Cloud Automation, K2, Salesforce) and deployment model. Contact their sales team via nintex.com or request a demo to obtain pricing quotes.
SourceStacker: 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.
Nintex: How long are Nintex free trials?
Nintex offers 30-day free trials for Workflow and Apps products. Process Manager, eSign, and DocGen trials are available, though exact durations are not specified on the trial page.
SourceStacker: 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.
