Hey kathrin
We’ve tried a few internal communication tools in our team as well. We mainly use Slack for day-to-day messaging, but we also started using MirrorFly for more customizable, internal communication features. It’s been helpful for things like integrating our own workflows.
Before that, we tested options like Mattermost and Rocket Chat for self-hosted flexibility, but MirrorFly ended up giving us the customization level we needed with less setup work.
