The short version

  • Only Salesforce Flows has a free tier, so it costs nothing to try first.
  • Each has a real cost: Salesforce Flows not suitable for highly complex scenarios with intricate decision-making or bulk data processing; 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: Salesforce Flows covers Visual flow 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.

Salesforce Flows

  • Not suitable for highly complex scenarios with intricate decision-making or bulk data processing
  • No automatic record locking, causing conflicts when multiple users update same records
  • Limited error handling compared to Apex
  • Requires Enterprise edition or higher for full capabilities
  • Auto-launched Flows cannot display screens to users
  • Complex dependency management and configuration challenges when deploying between environments

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

Salesforce Flows: Which Salesforce editions include Flows?

Salesforce Flow Builder is included in Enterprise Edition ($165/user/month) and above. Professional Edition lacks advanced automation capabilities and Flow Builder access. Starter and lower editions have limited Flow support.

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.

Salesforce Flows: What are the main limitations of Salesforce Flows?

Flows are limited by DML operations (max 150 data elements that modify data), SOQL queries (max 100 data elements that retrieve data), and are not designed for bulk processing. Auto-launched Flows do not support screens and have limited error handling compared to Apex.

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.

Salesforce Flows: Can Salesforce Flows integrate with external systems?

Yes, through MuleSoft connectors and Salesforce API Catalog. Pre-built connectors exist for systems like Asana, and admins can create custom connectors. Complex integrations may still require Apex or third-party platforms.

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.

Salesforce Flows: When was Salesforce Flow redesigned?

Flow Builder was introduced in Spring '19 as a replacement for the previous Flow Designer, providing a more familiar interface similar to other Salesforce Lightning Builder tools.

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.
