Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Rocket.Chat
- Resource-heavy (Node.js + MongoDB) and can be slow at scale on modest hardware
- Some enterprise features (engagement dashboard, scalability, advanced auth) require a paid plan
- UI can feel cluttered compared to Slack
- Mobile apps have historically lagged the web client in polish
Weechat
- Terminal-only; no native graphical UI, making onboarding difficult for non-technical users.
- Third-party plugins are required for any non-IRC protocol, and plugin quality and maintenance vary.
- No file sharing, image preview, video calls, or rich message formatting out of the box.
- Configuration is fully text-based with a steep learning curve for advanced setups.
