I'm David, a developer. I'm building a service that can contain channels like Slack since 5 months ago. It's not SaaS(It's free like reddit or HN)
It named SlashPage. It's live today. I'd love to your feedback.
I'm prepared a short video to make it easier to understand. https://youtu.be/zScnyiG_lok
