No, our 1,800+ components and frameworks for web, mobile, and desktop, including our Blazor Signature, are not sold individually. They are only available as part of a team license. However, we have competitively priced the product, so it only costs a little bit more than what some other vendors charge for their Signature component alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 1,800+ components and frameworks for a subscription fee that starts at $395 per month for a team of 5 developers. Additionally, we might be able to offer discounts based on currently active promotions. Please contact our product specialists today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue, 5 or fewer developers, and 10 or fewer total employees.
