We're using GitHub for version control as it's an industry standard for version control and our team has plenty of experience using it. We also found many features such as issues and project help us organize. We also really liked the fact that it has the Actions CI platform built in because it allows us to keep more of our development in one place. We chose Slack as our main communication platform because it allows us to organize our communication streams into various channels for specific topics. Additionally, we really liked the integrations as they allow us to keep a lot of our in formation in one place rather than spread around many different apps.
