Discord’s Privacy Crisis
Discord has recently faced intense criticism over multiple privacy and security concerns. The platform announced it would require users to submit government identification for age verification, began issuing copyright infringement violations for discussions about an old video game called “Cookies Bustle,” and most critically, security researcher Timothy Meadows discovered that Discord direct messages and authentication tokens were being written in plain text to local game log files when using Discord’s integration with games like Arc Raiders.
While Discord acknowledged the security issue and stated that Embark Studios released a hotfix, the company didn’t disclose the vulnerability in its newsroom or blog pages. Additionally, Discord’s integration with Persona (connected to Peter Thiel and global surveillance concerns) has further eroded user trust.
The Palantir Connection: Peter Thiel, co-founder of Palantir Technologies, is behind Persona’s identity verification system that Discord partnered with. Palantir is a major data analytics company known for its work with intelligence agencies, military defense contracts, and government surveillance programs. The company has provided services to the CIA, FBI, NSA, and various military branches, specializing in mass surveillance and predictive analytics. This connection means Discord users submitting ID verification would be funneling their personal data through infrastructure connected to one of the most prominent surveillance technology companies in the world.
The good news? The backlash has driven users to alternatives. TeamSpeak reached hosting capacity in several regions. Sto grew by 150,000 users in just over a week. Fluxer’s servers crashed from enthusiasm. Google Trends data shows a noticeable spike in searches for Discord alternatives.
Why Self-Hosting Matters
Self-hosting your chat server offers several critical advantages:
- Ownership: You control your data and communications
- Privacy: Limits the ability of prying eyes (governments or corporations) to access your conversations
- Permanence: Even if the software company goes defunct, your local server continues functioning
- Independence: Not subject to sudden policy changes or paywalls
The trade-off is convenience versus privacy. While you may still need mainstream services to meet new people online, you can move your core friend group to a self-hosted solution for sensitive communications.

Matrix Protocol with Element Client
Matrix is a communications protocol (the backend) with Element as the most popular frontend client. It’s free, self-hostable, and supports end-to-end encryption.
Pros
- Privacy-focused: End-to-end encryption and local account hosting
- Client flexibility: Nearly 30 different client options available
- Features: Chat exports, voice messages, polls, and threads
- Security: Device verification required when signing in on new devices
- Jitsi integration: Built-in conference calls
Cons
- Basic interface: Fewer features and user permission options than some alternatives
- Mobile call issues: Some problems starting and joining calls from mobile
- Historical concerns: Matrix received funding from Amdocs (an Israeli telecommunications company) from 2014-2017, which has raised concerns about potential intelligence ties, though no definitive links were found
The Amdocs connection stems from the company’s role in generating billing records for phone calls in America, with past investigations into whether these records were accessible for surveillance. While no hard evidence links Matrix to intelligence agencies, the historical funding connection is worth noting for privacy-conscious users.
TeamSpeak
TeamSpeak was the easiest server to deploy locally, offering a simple .exe setup file for Windows. It’s particularly compelling for replacing Discord voice channels.
Pros
- Easy deployment: Simplest local setup of all options tested
- Voice quality: Solid voice channels with AES-256 encryption
- Screen sharing: Native peer-to-peer screen sharing at 1080p
- Familiar interface: Similar enough to earlier versions that returning users will feel at home
- Active development: Team is responsive on social media and actively developing
Cons
- No persistent chat: Self-hosted servers don’t support persistent text chat
- Can’t delete messages: Once sent, messages remain
- Voice-first design: Must join voice channel before sending messages
- Mobile app costs $1: Only platform with paid mobile apps
- Dated UI: May feel unintuitive for users unfamiliar with TeamSpeak’s origins
TeamSpeak 3 offers stronger stability than TeamSpeak 6 (still in development) and includes a built-in voice recording tool with clear visual indicators when recording is active.
Rocket Chat
Rocket Chat stands out for its extensive user management capabilities, offering 194 configurable permissions and 217 adjustable settings.
Pros
- Granular permissions: Unmatched user management options
- Message management: Options to prune and export messages
- End-to-end encryption: Available (though not default)
- Recording: Built-in recording option in dev mode
- Topics: Can include topics when creating teams, channels, and discussions
Cons
- Aggressive paywalls: Upselling attempts more noticeable than other platforms
- Navigation: Room organization (teams > channels > discussions > threads) not obvious from UI
- Mobile issues: Unable to add workspace URL on Android app
Mattermost
Mattermost targets enterprises, advertising trust by the US Department of Defense and Fortune 500 companies.
Pros
- Playbooks: Unique automation feature for repeatable processes with tasks, checklists, and retrospectives
- Message composition: Rich text editing, headers, drafts, scheduling, reminders, and priority flags
- Business-focused: Strong for SOPs and test cases
Cons
- Recent restructuring: October 2025 changes deprecated features and imposed new limits
- User limits: Free tier reduced from 1,000 to 250 users; Entry Edition maxes at 50 users
- Ransom-like behavior: Existing self-hosted servers with over 250 users forced into paid subscriptions
- Government ties: US Department of Defense connection may concern privacy advocates
The restructuring behavior—effectively holding established servers “for ransom”—makes Mattermost difficult to recommend for long-term self-hosting.
Zulip
Zulip takes a different approach, organizing conversations more like a forum than a chat application.
Pros
- Forum-style organization: Folders > channels > topics (threads)
- Jitsi Meet integration: Easy screen sharing
- Saved snippets: Reusable text blocks for frequent messages
- Migration tools: Import from Mattermost, Slack, Teams, or Rocket Chat
- 120+ integrations: Extensive native integrations
Cons
- Steep learning curve: Most different from Discord’s interface
- Not a Discord clone: Unlikely first choice for like-for-like replacement
- Mobile limitations: Can’t create voice/video calls from mobile app
Zulip is well-built but serves different use cases. It’s ideal for teams that prefer forum-style organization over real-time chat.
Sto
Sto has gained significant traction as a Discord alternative, with one of the most visually similar interfaces.
Pros
- Discord-like UI: Familiar servers and channels structure
- Appearance customization: Themes, colors, fonts, emoji packs, compact mode
- Profile sharing: QR code generation for easy invites on mobile
- Growing community: 150,000+ new users in just over a week
Cons
- No screen sharing yet: Listed as “coming soon”
- No threads: Missing this key organizational feature
- Buggy: Friend requests delayed, profile changes not reflecting immediately
- Server overload: Experiencing degraded performance due to rapid growth
- Self-hosting difficulties: Team had trouble deploying self-hosted instance
Fluxer
Fluxer is essentially an open-source Discord clone with the most similar interface.
Pros
- Discord clone: Users will have no trouble adjusting
- Native screen sharing: Built-in, though quality limited on free tier
- Appearance options: Themes, fonts, spacing customization
- Personal notes: Built-in notes section
Cons
- Self-hosting documentation broken: GitHub link returns 404 error
- Connection issues: Servers overwhelmed like Sto
- File expiration: Files expire after 14 days (500MB) to 3 years (5MB)
- No mobile app: Only platform without mobile application
- Quality paywalls: 720p30 screen share free; 4K60 requires “Plutonium” subscription ($5/month)
Recommendations
There’s no single perfect Discord replacement. Your choice depends on priorities:
- Maximum privacy: Matrix/Element with end-to-end encryption
- Voice-first gaming: TeamSpeak for its ease of deployment and solid voice channels
- Business/enterprise: Rocket Chat for granular permissions (if paywalls acceptable)
- Forum-style organization: Zulip for teams preferring threaded discussions
- Discord similarity: Sto or Fluxer for easiest transition
The most practical approach may be a hybrid: use a self-hosted solution for your core friend group where privacy matters most, while keeping a mainstream service for meeting new people online. With tools like Tailscale or VPNs, your self-hosted server can be accessible from anywhere, giving you both privacy and flexibility.
As ID verification requirements and corporate surveillance continue expanding, the self-hosting renaissance represents an exciting opportunity to take back ownership of our digital communications.
