Top Recommended Replacements
Slack
FREEBest for Integration-Heavy Workflows
Why we like it
Industry-leading UX; 2,600+ integrations; 'Huddles' for quick audio syncs; superior search functionality.
Keep in mind
Free version limits history to 90 days; can become very expensive as teams scale.
Rocket.Chat
FREEBest for Data Sovereignty & Compliance
Why we like it
Fully open-source and self-hostable; HIPAA/GDPR compliant; allows white-labeling; 'Omnichannel' feature connects to WhatsApp/Telegram.
Keep in mind
Self-hosting requires technical maintenance; mobile app can be less polished than Slack.
Pumble
FREEBest for Unlimited Free History
Why we like it
Offers unlimited users and unlimited message history on the free tier; very familiar Slack-like interface; high value for small businesses.
Keep in mind
Fewer advanced integrations than Slack; limited built-in video conferencing power.
Mattermost
FREEBest for Developers & DevSecOps
Why we like it
Self-hosted Intelligent Mission Environment (IME); integrated 'Playbooks' for incident response; native support for Sovereign AI agents.
Keep in mind
Interface is built for technical users; can be overkill for non-technical departments.
Zulip
FREEBest for Threaded (Async) Communication
Why we like it
Unique topic-based threading keeps high-volume conversations organized; perfect for distributed teams across time zones.
Keep in mind
Steep learning curve; the 'threading-first' model feels counter-intuitive to users coming from Discord/Teams.
Element (Matrix)
FREEBest for Extreme Privacy & E2EE
Why we like it
Decentralized (Matrix protocol); End-to-End Encryption by default; no single point of failure; interoperable with other platforms.
Keep in mind
Initial setup for non-tech users can be confusing; video calls aren't as feature-rich as Teams.
Discord
FREEBest for High-Quality Voice & Community
Why we like it
Superior low-latency voice channels; unlimited history; very easy to manage huge communities with roles/permissions.
Keep in mind
No 'Threads' in the traditional professional sense; data privacy is lower; gaming-focused UI lacks corporate professionalism.
ClickUp (Chat)
FREEBest All-in-One productivity
Why we like it
Chat is directly attached to tasks and documents; no need to switch between apps; built-in AI for task generation from chat.
Keep in mind
The app can be slow due to its massive feature set; mobile chat experience is not as fluid as dedicated messengers.
Revolt
FREEBest Open Source Discord Alternative
Why we like it
Clean, privacy-first alternative to Discord; totally free; user-centric and community-driven development.
Keep in mind
Still in public beta; lacks many of the advanced bots and integrations of Discord or Slack.
