EasyRetro’s free plan allows you to create up to 3 public boards per month. You cannot create a team and there is 1 Survey per board.
TeamRetro on the other hand, offers more flexibility for teams trialing retrospective tools, with unlimited test runs in your trial and private boards from the start. Plus, it supports confidential brainstorming, so you’re not limited to public boards even when getting started. There is no limit on the number of retrospectives and health checks. You can create multiple teams to allow more people in your organisation to try running a retrospective tool for free.
