Download and Install Lasso 9 Server
This page briefly outlines the installation of Lasso 9 Server for each supported platform.
You can download Lasso 9 Server for FREE and run Lasso in "developer mode", which is fully functional but limited to 5 IP's and 200 connections per minute, so it will not support full deployment. Come back and buy the license to unlock its full power when you are convinced that Lasso gives you everything you need—and more!
