Comparison
Helix vs Session
Session deserves respect: no phone number, decentralized routing, open source. It's one of the most privacy-serious messengers out there. Helix shares the philosophy and pushes it further — our own network instead of a shared one, post-quantum encryption, full forward secrecy, and a complete suite for people who are genuinely targeted.
| Helix | Session | |
|---|---|---|
| Identifier required | None — closed, invite-only | None — random account ID (good) |
| Network | Our own onion network | Shared decentralized service-node network |
| Onion-style routing | Yes — ours, multi-hop | Yes — via the shared network |
| Post-quantum encryption | Yes | No |
| Forward secrecy / self-healing | Yes — continuously re-keyed ratchet | Limited — protocol trades some of this for its model |
| Voice & video | Yes, global, own transport | Voice yes; video limited |
| Built-in VPN | Yes — our own, zero-log | No |
| Self-custody wallet | Yes | No |
| Disposable mail | Yes | No |
| Plausible deniability / hidden app | Yes | No |
| Hardened device option | Yes (GrapheneOS phone) | No |
| Closed to strangers | Yes | Anyone with your ID can message you |
What Session gets right
Session threw out the phone number entirely — you get a random account ID — and routes messages over a decentralized network of service nodes rather than a single company's servers. That's a genuinely strong privacy posture, it's open source, and for people who want anonymous, no-account, decentralized chat, it's a serious option. We're fans of the direction.
Where Helix is the bigger system
- Our own network, not a shared one. Session rides a public decentralized network you share with everyone; Helix runs its own onion network, tuned for high throughput (gigabit-class, not the crawl of older onion networks) and under our control end to end.
- Post-quantum. Session's cryptography is classical; Helix is post-quantum end to end, so captured traffic stays unreadable for the long term.
- Full forward secrecy and post-compromise security. Helix's continuously re-keyed ratchet heals after a transient compromise; Session's design trades some of this away for its routing model.
- Closed network. On Session, anyone with your ID can message you; on Helix, only people you add can reach you at all.
- A complete suite. Global video, encrypted files, disposable mail, a self-custody wallet, a zero-log VPN, plausible deniability, one-tap burn, and a hardened phone — not chat alone.
Session is excellent anonymous, decentralized chat. Helix is the whole operational-security system — our network, post-quantum, and built for when you're the target.
