Choose Mattermost when your company wants an on-premises Linux/PostgreSQL chat server integrated with Jira/GitLab webhooks across Windows, Linux, and Android. Request early access to Wonek when your Apple-based engineering or leadership team wants true client-side MLS (RFC 9420) encryption where NO server database holds plaintext—plus direct QUIC P2P calls, screen sharing, chunk-resumable P2P files, CRDT docs, and shared calendars.
| Capability | Wonek (Pre-Release) | Mattermost |
|---|---|---|
| Client-Side End-to-End Encryption | Default MLS (RFC 9420) across all chats, calls & docs | No native E2EE — messages stored as plaintext in PostgreSQL |
| DevOps & Patching Burden | Zero — works immediately with zero servers to maintain | Requires Linux VM, PostgreSQL, TLS, S3 & rtcd TURN maintenance |
| Voice, Video & Screen Share | Direct QUIC P2P primary + encrypted relay fallback | Requires deploying rtcd media daemon + TURN server |
| Rich Code & Math Formatting | Rich text, inline code & mathematical formulas | Markdown, code blocks & LaTeX support |
| Collaborative Docs & Calendar | Offline-capable Yjs/Yrs CRDT docs + 5-view Calendar | Playbooks/boards; no built-in offline CRDT doc editor |
| Apple Watch & Push-to-Talk | Native watchOS calling/audio + 1:1 & group PTT | No standalone watchOS calling or PTT |
Self-Hosted Plaintext vs Client-Side Zero-Knowledge E2EE
Self-hosting moves trust from a SaaS vendor to your own cloud VPS and sysadmins—but if every message sits unencrypted inside PostgreSQL, a single compromised SSH key or S3 backup leaks years of company secrets. Wonek encrypts everything client-side via MLS (RFC 9420) so no database ever holds readable conversations.
Zero `rtcd` and `coturn` Maintenance
Getting crisp voice and screen sharing working across mobile CGNAT on self-hosted servers typically means debugging UDP firewall ranges and TURN credentials. Wonek's QUIC + smart port-prediction P2P works automatically out of the box.
| Technical Dimension | Wonek | Mattermost |
|---|---|---|
| Database Breach Blast Radius | Zero plaintext on server — ciphertext-only transient queue | Full historical chat & file exposure if server DB compromised |
| Wire Transport | QUIC / WebTransport with mandatory TLS 1.3 | HTTPS / TCP WebSockets + WebRTC |
| macOS Client | Native macOS app + compiled Rust core | Electron desktop wrapper |
| Large File Transfers | Direct P2P streaming with chunk-level resumption | Uploaded to server disk / S3 bucket |
| Mobile Push Privacy | Opaque wakeup; decryption strictly on device | Requires self-hosted push proxy or cleartext/ID push config |
Native Apple Craftsmanship Instead of Electron
Run fast native apps across Mac, iPad, iPhone, and Apple Watch with built-in CRDT docs and a 5-view shared calendar.
| Scenario | Recommended Platform | Why |
|---|---|---|
| Air-gapped Linux enterprise datacenter with Windows/Linux desktops | Mattermost | Runs completely inside your own corporate VLAN across all OSes |
| Security & founder teams wanting zero server plaintext without DevOps | Wonek | Client-side MLS E2EE eliminates PostgreSQL plaintext risk with 0 ops |
| Pair-programming screen share & multi-GB build transfers on Mac | Wonek | Direct P2P QUIC media and chunk-resumable file streaming |
| Teams combining Work channels & Personal life on iPhone/Mac | Wonek | Clean Personal and Work profiles under one account |
| Offline spec writing while traveling | Wonek | Yjs/Yrs CRDT documents merge cleanly after flights |
Frequently Asked Questions
Are Mattermost messages end-to-end encrypted?
No. Standard Mattermost stores messages in plaintext inside your server's database so server search and webhooks can read them. Wonek encrypts all messages, calls, files, and docs end-to-end on client devices.
Does Wonek support inline code and math like technical team tools?
Yes. Wonek supports rich formatting, inline code, and mathematical formulas alongside edits, replies, and pinned messages.
Do we have to manage TURN servers for Wonek calls?
No. Wonek prioritizes direct P2P over QUIC and provides automatic encrypted relay fallback with zero setup.
