CollabPortals vs Stacker: Simple Portal or Full App Builder?

Overview

CollabPortals and Stacker both let you create portals connected to Airtable, but they target different needs. CollabPortals is a focused portal builder at $10/month with unlimited users. Stacker is a no-code app builder with two platforms in 2026: the original Stacker Classic (Airtable and Google Sheets, starting at $9/month on Personal) and the newer Stacker Astra, which does not currently include Airtable.

If you are evaluating Stacker specifically for Airtable, you are evaluating Stacker Classic. That is worth bearing in mind before you sign up, since Classic's roadmap is not Astra's.

The entry price looks similar, but the products are shaped differently. Stacker gives you an app builder: you auto-generate a skeleton from your data, then spend time configuring pages, layouts, roles, and visibility before the app feels finished. CollabPortals gives you a portal out of the box. You pick your tables, pick your fields, set permissions, and share the link. The app-builder flexibility is great if you need it. If you do not, it is setup time you pay for twice.

Pricing Comparison

Feature	CollabPortals	Stacker Classic
Starting price	$10/month	$9/month (Personal)
Portal-ready plan	$10/month	Pro (around $199/month)
Portal users included	Unlimited	20 on Personal
Extra user cost	None	Scales with seat count on Pro
Record limit	No limit (Airtable plan limit)	Increases with tier
Apps/portals	Unlimited portals	Limited per tier
Annual pricing	$120/year	Annual discount available

Stacker Classic's entry price is genuinely low, but Personal caps at 20 portal users. Once you outgrow that, you move up to Pro (around $199/month). CollabPortals charges a flat $10/month with no user cap.

Example: A portal with 50 external users costs $10/month with CollabPortals. On Stacker Classic you would need Pro at around $199/month to get past the 20-user cap.

Prices current as of April 2026. Check the Stacker pricing page before committing, since the Classic versus Astra split is still evolving.

Where Stacker Wins

Stacker is a more comprehensive platform. It connects to 60+ data sources, offers a visual app builder with multiple layout options, supports role-based access with up to 3 roles per app on Pro, and provides two-way real-time Airtable sync. If you need to build internal tools, custom CRMs, or client portals with complex layouts, Stacker gives you more building blocks.

Where CollabPortals Wins

CollabPortals is purpose-built for one job: giving external users access to your Airtable data. It does that job for $10/month without user caps, and you do not need to learn an app builder to get started.

Key advantages:

• Set up in minutes instead of hours
• No per-seat costs that grow with your team
• Unlimited portals on every plan (Stacker limits you to 1 or 3)
• No record limits beyond your Airtable plan

Setup Experience

CollabPortals: Minutes

1. Connect your Airtable account (one-click OAuth)
2. Create a portal: pick your base, choose a user table, select the email field
3. Toggle table and field permissions on or off
4. Share the portal link

No builder to learn, no layout choices to make. Permissions are the only thing to configure.

Stacker: Hours

1. Sign up and connect your data source (Airtable or one of 60+ others)
2. Learn the visual app builder: pages, layouts, components
3. Design page layouts: choose list views, detail views, forms, and dashboards
4. Map fields to components and configure display options
5. Set up user roles and access permissions (up to 3 roles on Pro)
6. Configure record-level filtering and field visibility
7. Customise branding (limited CSS options)
8. Preview, test, and publish

Stacker auto-generates a basic app from your data, but you will spend time customising page layouts, configuring components, and learning the builder. Users report the platform can be slow to work in, which adds to the setup time.

What Users Say About Stacker

Stacker has a loyal user base that appreciates its visual builder and customer support. However, users consistently point out several pain points:

• Performance issues: Users report the platform can be "super slow to work on"
• Limited design flexibility: Customization options are constrained, leaving teams feeling locked into default aesthetics
• Schema sync delays: Changes to your Airtable schema only sync to Stacker once daily, not in real-time
• Data retrieval latency: Some users report 15-minute minimum intervals for data updates
• No real-time collaboration: No built-in chat or team coordination features
• High cost at scale: Per-seat pricing becomes prohibitive for larger teams

When to Choose CollabPortals

• You need external users to view, create, edit, or delete records in your Airtable base
• Budget is a priority and you want a flat $10/month with no per-seat fees
• You want a portal running in minutes, not an app built over hours or days
• You do not need a visual app builder, custom CRM, or internal tool
• You have more than a handful of users and want to avoid per-seat pricing

When to Choose Stacker

• You need a full no-code application with custom layouts and multiple data sources
• You are building an internal tool or custom CRM, not just an external portal
• You need to connect to data sources beyond Airtable (Salesforce, Google Sheets, etc.)
• You have the budget for Stacker Pro and need advanced role-based access
• You require enterprise features like SSO or dedicated account management

The Bottom Line

Stacker is a capable app builder for teams that need full applications with multiple data sources and complex layouts. But for the specific use case of creating Airtable portals for external users, it is dramatically overpriced.

CollabPortals gives you unlimited portals and unlimited users for $10/month. You do not pay for an app builder when a portal is all you need, and you do not spend the hours it takes to assemble one.

Frequently Asked Questions

Can I migrate from Stacker to CollabPortals?

Yes. Both tools connect to your Airtable base, so your data does not move. Set up a CollabPortals portal pointing to the same base and share the new link. No data migration needed.

Does Stacker's free trial let me test portal features?

Stacker offers a free trial on Classic. Personal ($9/month, 20 users) is enough to test basic portals, but moving past the user cap pushes you to Pro (around $199/month). CollabPortals also offers a free trial with all features included and no user cap.

What is the difference between Stacker Classic and Stacker Astra?

Stacker Classic is the original platform with active Airtable and Google Sheets support. Stacker Astra is the newer platform that does not currently include Airtable. If you are building on Airtable, you are using Classic, and Classic's long-term roadmap is not Astra's. Worth factoring in before a long-term commitment.

Which tool syncs with Airtable faster?

Both tools sync in near real-time. Stacker advertises a roughly 10-second sync delay for data, though schema changes only sync once daily. CollabPortals reads and writes directly to Airtable via the API, so changes appear immediately.

What happens if I outgrow CollabPortals?

If your needs expand beyond portals to full app building, you can switch to Stacker or another platform. Since your data stays in Airtable, there is no lock-in. Many teams start with CollabPortals for portals and only move to a full app builder if they genuinely need one.
