A modern interface, minus the mess.
Keep FileMaker doing what it does best. Rapid Stack untangles your existing interface from the scripts and relationships it has grown into, so your UI lives in one clean place and your data stays data.
low-code builder
Drag, drop, done.
Compose dashboards, forms and lists on a responsive grid. No pixel-pushing, no layout fiddling, just clean screens that work everywhere.
schema validator
Good design, enforced.
Every layout is checked against a strict UI schema. Bad design decisions get caught before they ship, so every screen stays consistent.
ai guardrails
Guardrails for humans and AI alike.
The schema that keeps your own layouts consistent keeps AI agents on the rails too. They produce valid, consistent layouts, not one-off spaghetti code you have to untangle later.
clean separation
UI out. Logic in.
Pull the interface out of your scripts and database schema. Data stays data, scripts stay logic, and the UI lives where it belongs.
Built on MUI. Trusted by millions.
MUI is one of the most widely used UI frameworks on the planet, backed by years of design work and serious R&D investment. Rapid Stack puts all of that inside FileMaker, so you get world-class components without building a single one yourself.
Battle-tested MUI components
Real MUI buttons, data tables, charts, tabs and dialogs, refined by years of use in products all over the world.
Responsive by default
Layouts adapt from widescreen to iPad to iPhone without a second layout.
Accessible and polished
Keyboard support, sensible contrast and smooth interactions out of the box.
Three steps to a better-looking solution.
01
Add the runtime
Copy the Rapid Stack runtime into your solution and store it wherever suits you: a field, a layout object, a script step or a record. It runs right inside a Web Viewer.
02
Design your layouts
Build grid-based layouts, drop components into tiles and connect each one to a data source. Set your brand colours, fonts and icons once, and every screen follows.
03
Wire up your scripts
Add a FileMaker script for each data source. Your scripts serve the data, Rapid Stack takes care of the interface.
