Give every customer a login to a space that's just theirs: their projects, their invoices, their files — pulled live from your base.
Easily create powerful software interfaces for your business's data, without leaning on developers.
Link your Airtable base, Google Sheet or SQL database. Stacker reads your tables and fields and keeps them in sync, both ways.
Stacker generates a working app from your data. Pick layouts, filter and sort, add forms and buttons — no code required.
Invite teammates, customers and partners to log in. Permissions decide exactly which records and fields each person sees.
Make your data work harder. Build interfaces that bring the right records to the right people.
Stacker automatically creates a working app based on your tables, fields and relationships.
Choose the right layout, then filter, sort and display your data however you like.
Build forms to create records, pages to edit them, and buttons that automate the important tasks.
Fully flexible permissions give you total control over which data each user can access and which actions they can take.
Share your data with different groups of users by inviting them to log in to your Stacker app.
Branded portals on your own domain, with custom CSS and scripts when you need to go further.
88,500+ teams have built the software their business actually needed — without waiting on a developer.
“Stacker was a no-brainer solution to fit on top of the existing data in our spreadsheets.”
“It's like having a development team in your back pocket.”
“My team has become so self-sufficient and effective that we really can operate as our own little unit without needing extra support.”
8 hours a week
“Thanks to Stacker, the TED Fellows team each gets 8 hours — or roughly one working day — back per week.” TED built a complete application management system for their fellowship programme in Stacker.
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.
