When we say "Unlimited," we mean that. The new Unlimited plan now includes access to both versions of Teamplify: Cloud and On-premises, without any limitations.
All paid plans include a free trial that immediately starts in the "Unlimited" mode. No credit card is required, so you can try first and decide later.
No matter which Teamplify version you choose, get started with the Cloud first. After you sign up, you can either immediately start using it, if you prefer Cloud, or navigate to Organization Settings and grab your license key for the On-premises version.
