Choose Jami if you want a GPL serverless OpenDHT desktop softphone on Linux/Windows/Android. Request early access to Wonek (for iPhone, iPad, Mac, and Apple Watch) when you want P2P calling and file transfers that actually thrive on mobile 4G/5G CGNAT via proprietary port prediction over QUIC—backed by reliable offline ciphertext queuing, MLS (RFC 9420) groups, Apple Watch PTT, CRDT docs, and shared calendars.
| Capability | Wonek (Pre-Release) | Jami |
|---|---|---|
| Offline Message Reliability on iPhone | Guaranteed via ciphertext-only offline server queue | Often delayed if sender & receiver aren't awake simultaneously on DHT |
| Mobile 4G/5G CGNAT Call Success | High-rate direct P2P via proprietary port prediction + QUIC | Standard SIP/ICE frequently falls back to TURN relays |
| Group Chat & Key Sync | IETF MLS (RFC 9420) O(log N) multi-device sync | Git-based swarm sync over DHT (can lag across sleeping phones) |
| Large File Transfers | Direct QUIC P2P with chunk-level resumption | P2P file transfer (requires simultaneous online state) |
| Push-to-Talk & Apple Watch | 1:1 & group E2EE PTT + native Apple Watch app | No Apple Watch calling/PTT app |
| Collaborative Docs & Calendar | Built-in Yjs/Yrs CRDT docs + 5-view Shared Calendar | Not included |
Fixing the Two Biggest Headaches of Mobile P2P Apps
Anyone who has tested pure DHT communicators on iPhones recognizes two frustrations: calls take 8–15 seconds just to locate a peer on the distributed hash table, and messages sent while a friend's phone is asleep sit stuck until both phones happen to open at once.
Wonek uses ultra-fast signaling and a ciphertext-only offline queue for instant wakeups—then establishes direct device-to-device QUIC connections across mobile CGNAT using proprietary port prediction so media flows straight between peers.
Modern QUIC + MLS vs Legacy SIP + X.509 Chains
Replacing legacy SIP/ICE/DTLS stacks with unified QUIC / WebTransport (TLS 1.3) and Rust MLS (RFC 9420) eliminates head-of-line blocking and streamlines multi-device sync across iPhone, iPad, Mac, and Apple Watch.
| Technical Layer | Wonek | Jami |
|---|---|---|
| Wire & Media Transport | Unified QUIC / WebTransport with mandatory TLS 1.3 | OpenDHT + SIP + pjproject ICE / DTLS-SRTP |
| End-to-End Encryption | MLS (RFC 9420) in native Rust core + Noise QR | TLS/DTLS X.509 device certificates + swarm encryption |
| Connection Setup Speed | Fast QUIC 1-RTT setup without 10-second DHT lookups | OpenDHT peer lookup can add noticeable call ring delay |
| Strict Firewall Fallback | Automatic latency-measured encrypted relay | Community or self-hosted TURN server |
| Profile Contexts | Personal & Work profiles under one account | Multiple local SIP/Jami accounts |
Chunk-Resumable Transfers & Built-In Collaboration
Interrupted large file transfers pick up from the exact last verified chunk, while CRDT documents and a 5-view shared calendar turn Wonek into a complete daily driver.
| Scenario | Recommended App | Why |
|---|---|---|
| Linux desktop LAN/SIP peer calling without any central server | Jami | Pure GNU OpenDHT architecture with SIP support on Linux |
| Fast call ring times & direct P2P across 4G/5G CGNAT on iPhone | Wonek | Skips slow DHT bootstrap and traverses mobile CGNAT over QUIC |
| Texting someone whose iPhone is currently in Airplane Mode | Wonek | Ciphertext-only offline queue delivers even after you go offline |
| Resuming a 4 GB file transfer interrupted by a subway tunnel | Wonek | Automatic chunk-level resumption over QUIC |
| Team & family planning on Mac, iPad, iPhone & Watch | Wonek | Includes CRDT docs, 5-view calendar, PTT, and Personal/Work profiles |
Frequently Asked Questions
Why do calls ring faster in Wonek than in DHT-based P2P apps?
Wonek avoids slow distributed-hash-table lookups on mobile wake, negotiating direct QUIC P2P paths rapidly with automatic encrypted relay fallback if UDP is blocked.
What happens if I send a message in Wonek and then turn off my own phone?
Because Wonek stores opaque MLS-encrypted ciphertext in an offline delivery queue until the recipient wakes, your message still arrives even if your own phone goes offline.
Are Wonek's file transfers peer-to-peer like Jami's?
Yes—with the added advantage of chunk-level resumption over QUIC so temporary network drops never restart large transfers at 0%.
