Build on the data you already have — wherever it lives.
Airtable, Google Sheets, Postgres, MySQL, Salesforce or Stacker's own tables. Connect one or several and Stacker gives them a single interface, with one set of logins and permissions.

One app, many sources
Most businesses don't have one database. They have a base, a few sheets and a production system. Stacker sits on top of all of them.
Combine sources in one app
Customers from Airtable, orders from Postgres, price list from a sheet — linked together and shown on one page.
Live, two-way
Reads are fast because Stacker keeps a synced copy; writes go straight back to the source so it stays the system of record.
One permissions model
Whatever the source, the same row- and field-level rules apply, enforced before anything is sent to the browser.

Supported today
Connect in a couple of clicks with OAuth or a connection string. Stacker introspects tables, fields and relationships and keeps them in sync.
- Airtable — bases, linked records, attachments, views
- Google Sheets — tabs as tables, rows as records
- Postgres & MySQL — read and write against your schema
- Salesforce — objects, fields and relationships
- Stacker tables — a built-in database when you don't have one
An admin panel on your production database, without the risk
Give ops and support a safe way to look things up and fix records. Stacker connects read-write or read-only, and every edit is permission-checked and logged.
- Read-only or read-write connections
- Allowlist which tables and columns are exposed
- Static egress IPs for your firewall rules
The same rules everywhere
Permissions are defined once per role and applied no matter where a record comes from — so a customer sees their Airtable project and their Postgres invoices, and nothing else.
- Scope records by the logged-in user
- Hide fields per role
- Audit who changed what, and when
Questions? We're glad you asked.
- Can I start without any existing data?
- Yes. Stacker tables give you a built-in database. Create tables and fields in Stacker and move to an external source later if you need to.
- Does Stacker copy my data?
- Stacker keeps a synced copy so the app is fast and permissions can be enforced server-side. Your source remains the system of record, and you can disconnect at any time.
- How do I connect a database behind a firewall?
- Stacker connects from a fixed set of egress IP addresses you can allowlist. Connection details are encrypted at rest.
- What about a source you don't list?
- Many teams sync other systems into Airtable, a sheet or Postgres first, then build on that. Enterprise plans include additional data connectors — get in touch to discuss.
Secure and safe
Stacker is audited and certified by industry-leading third-party standards. Your data stays in your Airtable, Google Sheet or database — Stacker reads and writes it on your behalf, with every permission rule enforced server-side.
