Let customers, clients and partners self-serve through a branded portal
Give every customer a login to a space that's just theirs: their projects, their invoices, their files — pulled live from your base.
- Secure logins via their email address
- Give access to view and edit their own records
- Control exactly which rows and columns they see
Build custom tools yourself — in minutes, not months.
Easily create powerful software interfaces for your business's data, without leaning on developers.

Connect your data
Link your Airtable base, Google Sheet or SQL database. Stacker reads your tables and fields and keeps them in sync, both ways.
- 02
Create your app
Stacker generates a working app from your data. Pick layouts, filter and sort, add forms and buttons — no code required.
- 03
Share with your users
Invite teammates, customers and partners to log in. Permissions decide exactly which records and fields each person sees.
Create business software without seeing a line of code
Make your data work harder. Build interfaces that bring the right records to the right people.
Powered by your data
Stacker automatically creates a working app based on your tables, fields and relationships.

Made for interaction
Build forms to create records, pages to edit them, and buttons that automate the important tasks.
Flexible access control
Fully flexible permissions give you total control over which data each user can access and which actions they can take.
