Best for client portals and internal tools on top of your data
Stacker turns spreadsheets and databases into portals and internal tools, with permission rules and a custom domain. Starter at $29 a month stops at 1 app and 5 internal users, the larger limits need Plus at $149, and its AI agents are sold separately.
Who Stacker is for
- Fits if you want a client portal on top of a spreadsheet or database
- Works for small teams of up to 5 inside users and one app
Who Stacker is not for
- Tight if you grow: Starter is 1 app, 5 internal users, 50 external users
- Pricey if you want unlimited outside users and custom scripts, which need Plus at $149 a month
- Watch out: SQL and Salesforce connectors and SSO are Enterprise only
- Watch out: the AI agents are sold as a separate product
- Skip it if you want a free plan, as only a 30-day trial exists

Keep Stacker, or make your own?
Keep it
To replace Stacker you would be making a builder that other people can use without writing code. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 39 of the 89 other AI app builders grade higher. It costs $348 a year.
What you could not
- A builder that other people can use without writing code.
- A tool that builds and hosts other apps.
- Connections to other products, each kept working as those products change.
- Databases with views, filters and links between them.
What this rests on. Stacker’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Stacker?
Stacker is a no-code platform that turns data held in Airtable, Google Sheets or a SQL database into apps people log in to, such as customer portals, internal tools and partner apps. Your data stays in its source and Stacker reads and writes it, with permission rules enforced on the server.
Worth knowing
- Starter is capped at 1 app, 5 internal users and 50 external users.
- Unlimited external users, 100,000 records per app and custom CSS and scripts need Plus at $149 a month.
- SQL and Salesforce connectors and enterprise SSO are Enterprise-only.
- Stacker's AI agents are sold as a separate product and are not part of these plans.
Key features
- Customer portals
- Give customers, clients and partners a branded login where they see and edit only the records and columns you allow.
- Internal tools
- Build interfaces for your own team on top of an existing base or spreadsheet, without waiting on developers.
- Two-way data sync
- Stacker links to Airtable, Google Sheets and Stacker's own tables on every plan, and keeps the source and the app in sync both ways.
- Permission rules
- Row- and column-level access is set per role and enforced on the server; Plus allows 3 roles per app and Enterprise unlimited roles.
- Custom domain
- Starter includes one portal on a custom domain, and Plus adds custom CSS and scripts for finer control of the look.
