Lift applications can be deployed to the Run@CloudBees cloud hosting platform. As of May 2011, the company allows free Tomcat-based .war file application hosting, with optional database instance.
There’s nothing special you need to do with your Lift app to deploy to CloudBees. You can use their command-line tools to deploy your .WAR file or try the CloudBees SBT Plugin.
There are step-by-step instructions in the Cookbook, and CloudBees have also introduced a ClickStart as a way to deploy applications.
