Insider Program. Monthly and yearly subscriptions.

Insiders have access to dozens of additional extensions and tools with a subscription.

A growing collection of extensions

There are ~20 extensions freely available to use with WebSharper, covering the most important areas such as charting (Highcharts), visualization (Google, D3), maps (Bing, Google, Leaflet), key WebSharper abstractions (formlets, piglets, and UI.Next), and basic mobile libraries (jQuery Mobile, PhoneGap). The full list is available on the Downloads or the Extensions page.

However, if you are regularly building WebSharper applications, we recommend that you enroll in the WebSharper Insider Program, and benefit from the multitude of additional extensions and tools via the subscriptions below.

Work with any WebSharper extension

The licencing fees for the premium Kendo extension (and even 2.X line) has been far and above worth the sheer amount of trouble saved to work with their API.
