Build complex business logic, visually

Rules Engine

Resco’s low-code Rules Engine lets you define and manage advanced logic across your apps with ease, no Power Fx required. Build intelligent behavior into forms, calendars, views, planners, and more. When you need full control, switch to JavaScript. All while supporting full offline use.

    • The rules in Resco are an absolute game changer for me.

      As a non-technical consultant, it is very easy to modify the app and add quite a bit of advanced logic to it, without having to ask technical colleagues.

Visual rule builder

Use intuitive, point-and-click tools to create client-side business logic, define conditions, and control app behavior. 

Automation made simple

Simplify work by automating actions. First, define the triggering condition: for example, when an item is created, displayed, changed, clicked, or saved. Then define the steps to perform, such as fetching data, populating form fields, calculating values, creating records, or generating reports.

Offline-first execution

Load, calculate, and act on complex conditions even with no signal. The engine supports dynamic logic execution and local decision-making on the device. 

Multi-scenario support

Apply logic across your app: forms, views, calendars, route planners, and schedulers all respond to your custom rules.

Advanced capabilities with optional coding

For edge cases, you can extend rules with Resco’s JavaScript API.
