Stacker review

A practical way to turn existing data into portals and internal apps, but Starter’s caps and Plus’s $149 monthly price matter.

The bottom line

Worth considering if your data already lives in a supported source; check the user caps before switching.

Stacker turns Airtable, Google Sheets, or SQL data into customer portals, internal tools, and partner apps, with two-way syncing, access controls, forms, and automated buttons. That makes it a plausible fit for teams that want an app layer without rebuilding their data in another system.

The pricing page lists Starter at $29/month for one app, 50 external users, and five internal users. Plus is $149/month and adds unlimited external users, up to 100,000 records per app, and 20 tables per app. There’s no free plan, the trial is 30 days, and annual prices aren’t listed. The Reddit threads we read aren’t about this Stacker product, so they don’t offer useful sentiment evidence.

Good fit if

  • Teams already using Airtable
  • Portals with defined access rules
  • Internal tools built around existing data

Skip it if

  • Teams needing multiple Starter apps
  • Projects that need a free plan
  • Buyers requiring published annual pricing

01What Stacker actually does

Stacker turns data in Airtable, Google Sheets, or SQL databases into apps: customer portals, internal tools, and partner-facing interfaces. Instead of building a separate app from scratch, you create layouts around existing tables and fields, then decide what different users can see and do.

The product supports two-way syncing with connected data sources, and can generate an app from your tables, fields, and relationships. You can add forms and buttons to create or edit records and automate tasks, while access controls set permissions for records, fields, and actions. Custom domains, branding, CSS, and scripts provide options for making the result look less like a generic portal.

The basic pitch is useful if your data already lives in a supported source and you need a usable interface around it. Stacker is not a general-purpose replacement for a database: your app is built on top of the data you connect.

02Where Stacker is strong

Stacker’s clearest advantage is that it can turn existing operational data into a front end without requiring a coded app project. That can make sense when a spreadsheet or Airtable base has become awkward to share with customers, partners, or colleagues, but moving the underlying data would add unnecessary work.

The feature set covers the basics of a working portal: layouts, filtered and sorted views, forms, buttons, and permissions. Two-way syncing is important for this setup because the app is intended to work with the connected data, not just display a one-time copy. Custom domains and branding help if external users will see the interface; custom CSS and scripts add more room to tailor it.

Pricing starts at $29 per month for Starter, according to the published pricing details. That plan includes one app, 50 external users, five internal users, 10 tables, and one portal with a custom domain. A 30-day free trial is listed. For a small team with one contained portal, those limits make the entry plan’s scope fairly easy to assess before committing.

03Where it falls short

The user and app caps matter more than the $29 starting price. Starter allows 50 external users and five internal users, with one app and 10 tables. If your portal has a broad customer base or your staff need internal access too, check both counts before switching. The published pricing details list Plus at $149 per month, with unlimited external users, 100,000 records per app, three roles per app, 20 tables per app, and custom CSS and scripts. They do not state a Plus internal-user limit.

Annual prices are not published on the vendor's site, so we can’t compare annual savings. Enterprise pricing is also not published; its listed inclusions are Enterprise SSO, SQL and Salesforce connectors, unlimited roles, tables, and apps, a dedicated account manager, custom SLAs, and a security review. One point to confirm before buying: SQL is named as a supported data source, but SQL connectors are specifically listed under Enterprise plan inclusions.

Stacker may be a poor fit if you need more than the plan’s record or table limits, or if Enterprise-only terms push the cost beyond budget. Compare the app and user caps against your real rollout, not just the starting price.

04Stacker pricing: what you'll actually pay

Stacker starts at $29 per month for Starter, with no free plan and a 30-day trial. Starter includes one app, 50 external users, five internal users, 10 tables, and one portal with a custom domain. That external-user cap is worth checking before you move a customer-facing portal onto it.

Plus costs $149 per month: $120 more than Starter, or about 5.1 times the price. It includes 100,000 records per app, unlimited external users, three roles per app, 20 tables per app, and custom CSS and scripts. The published pricing details do not say that Plus includes multiple apps, so confirm that requirement before switching.

Enterprise pricing is not published; its listed features include SSO, SQL and Salesforce connectors, and unlimited roles, tables, and apps. No add-on prices are listed. Starter and Plus are billed monthly; annual prices are not published, so there is no stated annual discount to compare.

05Switching to (or from) Stacker

Stacker connects to Airtable, Google Sheets, or SQL databases, and the product description says those connections support two-way syncing. If your data already lives in one of those sources, the move may avoid a full data-platform migration. You would still need to build or generate the app, configure layouts, forms, automations, and access rules, then check that they match your existing workflows.

Before leaving, ask how to export app configuration, permissions, and automation logic. The published materials do not publish export details, so we can’t confirm what transfers or how much rebuilding a move would require. Your underlying data may remain in its source, but the Stacker-built interface and rules may need to be recreated elsewhere.

No Reddit posts or comments were included in the published material, so we can’t responsibly say what users report as reasons for leaving. Check export options and user caps directly before committing.

From the threadsWhat users say

The Reddit material does not include direct reviews of Stacker, the no-code app and portal builder; the posts discuss unrelated products with the same or a similar name. Those users range from positive about a Taco Bell value hack and customizable jewelry storage to negative about tight jeans and a golf training system.
