Hello! I am looking for suggestions for Slack alternatives that meet the following (likely impossible) criteria:
- Modern UI
- Self-hosted FOSS
- Actively developed, or at least stable and maintained
- Comprehensive API for integrations
- Non-shit strategy for determining which device to send notifications to
Regarding UI, I am hoping to find something with a more streamlined implementation of threaded conversations - this is my primary complaint with Slack.
I know there are tons of articles on Slack alternatives, but I'm hoping for a more technical perspective. Are there any Matrix-based options that are refined enough for a small team to rely on as primary method of communication?
Thank you!
