Technologist Testimonials

Durandal is built to handle the plumbing and makes it easier for me to focus on building rich webs apps with JavaScript faster. Only when you've written SPA's without Durandal do you realize how much it saves you!

John Papa, Author & Microsoft Regional Director

The MapsJS project team has been successfully using Durandal for its single page app-dev. MapsJS is a free HTML5 map control for building complex cross-platform geospatial applications. Many of our larger customer projects required an SPA framework to minimize dev time and keep the projects well organized. We liked using Durandal so much that we decided to add support for it in our latest release.

Brian Hearn, MapsJS Lead Architect

Durandal is the missing piece in my Knockout SPA toolkit. It handles the infrastructure and lets me focus on delivering functionality. Powerful, yet lightweight, pluggable and built on proven patterns from WPF/Silverlight development.

Hans FjÀllemark, Freelancing HTML5 consultant - Tellurian Interactive

Durandal brings capabilities from Caliburn.Micro to JavaScript clients that we sorely missed. Love the screen management and convention-based composition of Views and ViewModels.

Ward Bell, V.P. of Technology - IdeaBlade

Rob set high standards with Caliburn.Micro... When we develop WPF/Silverlight applications using it, we get better code organization, flexibility and, ultimately, higher code quality and team productivity. He's done it again with Durandal - which brings all of the same qualities to the world of HTML5 applications. Amazing work!

Srdjan Strbanovic, CTO - Cignium Technologies
