Yes. You can activate Wisej Web Developer on 3 machines: Work, Laptop and Home.
You can also deploy to 1 server using the free Server License included with your Developer License.
You need 1 Server License for each additional deployment. For example, if you have 3 developers and need to deploy on 10 servers, you need to purchase 3 Developer Licenses and 7 Server Licenses (7 because the 3 Developer Licenses include a free Server License each).
A server is a web server instance (IIS or Cassini for now), whether the web server is running on a virtual machine, on a local server, on the Cloud or as a service. For example, an Azure Web Site instance is a server, an Amazon EC2 instance is a server.
No. Wisej licenses are perpetual. Only the free update period expires 1 year after the purchase of the license.
You will be able to use all new builds, updates, releases for 1 year from the purchase date. You can extend the “Free Updates” period at any time and for as long as you like.
The cost is 50% of the full licence price.
