Stacker

Stacker is a no-code app platform built around a simple premise: your business data already lives somewhere — Airtable, Google Sheets, Salesforce — and your team and clients need a structured, permission-controlled interface on top of it. Rather than stitching together workarounds or hiring developers, Stacker lets you generate that interface directly from your existing data schema.

The positioning has shifted toward AI-assisted app building. You can describe the kind of app you need, upload a spreadsheet, and get a working starting point. The output isn't magic — you'll still configure roles, adjust layouts, and connect your data sources — but it compresses the initial setup considerably.

What You Can Build

Stacker's use case taxonomy breaks into four buckets: customer portals, work management tools, flexible CRMs, and process trackers. In practice, these overlap. A client-facing project portal often needs internal task management alongside it; a partner workflow app often doubles as a lightweight CRM.

Each app is built from connected views of your data: list views, detail pages, Kanban boards, inbox-style views, and forms. Row-level record permissions mean you can configure each logged-in user to see only their own records — the standard requirement for any multi-tenant client portal. Comments and notifications are included across plans.

Pricing Breakdown

All plans include a custom domain. The distinction between "external users" (portal end users — clients, partners) and "internal users" (your team members who build and manage the apps) matters here. Starter's 50-external-user cap is workable for small agencies or early-stage portals; Plus removes that ceiling entirely for $149/month, which is the tier where Stacker becomes viable for most production use cases.

A 14-day free trial gives access to all features — no credit card required.

Notable Customers

Stacker's case studies skew toward operationally sophisticated teams. TED built a complete application management system for their Fellowship programme on Stacker, recovering roughly eight hours per week per team member. Meow Wolf runs partner workflow apps for their immersive art installations. Zapier uses Stacker internally to manage employee development budgets. Segment built a self-serve portal for their startup programme on it. These aren't marketing-fluff logos — they're examples of Stacker handling multi-stakeholder workflows at real scale.

Security and Compliance

Stacker references third-party security audits and certifications on its site, positioning it as enterprise-ready. For teams with compliance requirements, it's worth requesting specifics from their sales team — the homepage mentions certifications without naming them explicitly.

Where It Fits

Stacker is a strong choice when your data source is already established (particularly Airtable or Salesforce) and you need a polished, permissioned interface without engineering work. The Salesforce integration is especially useful for sales and customer success teams building partner portals that need to reflect live CRM data.

The tradeoff versus competitors like Softr is design flexibility — Stacker's generated interfaces are clean and functional but less customizable visually. Teams that need pixel-level control over their portal's look will hit friction; teams that prioritize data integrity and permission logic over aesthetics will find it efficient.

The Plus plan at $149/month is where Stacker's value proposition clicks into place: unlimited external users, data connections, and enough records for most business operations. Starter at $29/month is genuinely useful for validating a use case before committing.

Note: the frontmatter has price_starts_at: 79 which is outdated — the current Starter plan is $29/month. Worth updating that field too.
