Why People Look for Stacker Alternatives
1. Need Forms + Portals Together
Stacker excels at portals but has minimal form capabilities. Most teams pair Stacker with a dedicated form builder (Fillout, Jotform), which means managing two platforms, two bills, two sets of permissions.
Common scenario: Use Stacker for client portal + Fillout for intake forms + Zapier for automations = 3 tools, $228/mo, complex integration maintenance.
2. No Automations Included
Stacker doesn't offer workflow automation. Simple tasks like "send email when record is updated" or "create task when form is submitted" require Zapier or Make—another subscription and integration complexity.
3. Pricing Adds Up with Multiple Apps
Stacker charges per app. Need a client portal AND an internal dashboard? That's 2 apps. With per-app pricing, costs escalate quickly. Pro plan ($149) only includes 5 apps before hitting Business tier ($349).
4. Tool Sprawl is Exhausting
Managing Stacker + form builder + automation tool + document generator means:
- Multiple logins and dashboards
- Separate billing and renewals
- Different support channels
- Integration maintenance
- Training team on 3-4 platforms
5. Want Predictable Bundle Pricing
As workflows expand, stitching together point solutions becomes expensive and fragile. A unified platform with predictable pricing simplifies budgeting and reduces vendor management.
6. Document Generation Missing
Stacker doesn't generate documents (contracts, invoices, reports from Airtable data). Teams need yet another tool (DocuGen, Formstack Documents), adding to subscription fatigue.

Detailed Comparison: Filla vs Stacker
Client Portals
Stacker: Best-in-class portals. Granular permissions, beautiful layouts, powerful filtering, custom domains, white-labeling. This is Stacker's core strength.
Filla: Comprehensive portals with filtered views, permissions, custom branding, responsive design. Feature parity for most use cases. Stacker may have edge cases with more complex permission scenarios.
Verdict: Stacker has slight edge on portal depth. Filla is excellent for most portal needs and includes much more.
Forms

Filla: Full-featured forms with conditional logic, multi-step flows, linked records, auto-sync with Airtable schema. Forms are a core strength, not an afterthought.
Verdict: Filla wins. Stacker users buy separate form tool.
Automations
Stacker: Not offered. Users need Zapier, Make, or custom webhooks.
Filla: 17 on-demand processor tools included. Run CSV export, duplicate detection, document generation, and more on your Airtable data — no code or external tools required. Note: a multi-step workflow builder is not yet available.

Frequently Asked Questions
Can I use Filla if I'm currently on Stacker?
Yes. You can run both in parallel during migration. Your Airtable data stays in place, so there's no data risk.
Do I have to cancel Stacker before trying Filla?
No. Test Filla during the free trial while keeping Stacker active. Switch when ready.
What happens to my Stacker portals when I switch?
Portal layouts need to be rebuilt in Filla (no direct export). But your Airtable data stays intact, and Filla's visual builder makes recreation straightforward.
Does Filla support Google Sheets and SQL databases like Stacker?
Not currently. Filla is built exclusively for Airtable. If you need multi-source portals (Airtable + Google Sheets + SQL), Stacker is better suited.
Are Filla's permissions as granular as Stacker's?
Filla supports role-based permissions, row-level filtering, and field-level access control. For most use cases, this is sufficient. Stacker has more advanced permission modeling for complex enterprise scenarios.
Can I get unlimited apps with Filla like Stacker Business?
Yes. Filla doesn't charge per-app. Create as many portals as you need within your plan.
What if I'm using Stacker + Fillout + Zapier today?
Filla replaces all three. You'll consolidate to one platform, save $160-200/mo, and eliminate integration maintenance.
Is Filla harder to use than Stacker?
Actually easier for most users. Stacker has a steeper learning curve. Filla's visual builders are designed for non-technical users.
Will my Stacker automations work with Filla?
If you're using Zapier with Stacker for Airtable data tasks, Filla's 17 processor tools handle many common post-submission operations natively — eliminating some Zapier dependencies.
