About Stacker
Stacker turns an Airtable base, a Google Sheet or a SQL database into a customer portal, internal tool or partner app. It is built for teams that already keep their data in spreadsheet-style tools.
What it does
Stacker reads your tables and fields, then generates an app that people can log in to. Changes are kept in sync with the source data in both directions. Each user can view and edit only the records you allow, so a client sees their own projects, invoices and files and nothing else.
Key features
- Customer portals with a login for each client
- Internal tools built on Airtable or Google Sheets
- Two-way sync with your source data
- Control which rows and columns each user sees
- Secure logins using email addresses
Who it's for
Operations and small business teams that want a custom interface on top of spreadsheet data, without writing code or waiting for developers.
Pricing and good to know
Stacker offers a 30-day free trial, and the site says no credit card is needed to start. Check the pricing details for paid use before you commit. The company states it holds SOC 2 Type II certification, which can be useful when a security review is part of your decision.
