Every Slack workspace that installs Gator starts with a three month free trial. You and your coworkers can send unlimited Gator messages during this trial to help you evaluate Gator.
When your trial is complete, you can upgrade to a paid Gator subscription by saying "/gator upgrade" in Slack. Gator will give you a link to the pricing page along with some statistics about how you and your coworkers used Gator during the trial.
If you choose not to upgrade to a paid subscription, you and your coworkers can still use Gator to send 10 messages per month. If you use all 10 messages, you'll need to either upgrade to a paid plan with "/gator ugprade" or wait until the first day of the next month.
