Yes — the link appears to be for Vector Messenger by Vector Privacy, not the older Matrix/Element product that was also once called Vector.
It is a relatively new, open-source
open beta messenger built around Nostr relays. Its stated design is: no phone number/email signup, public code, NIP-17/NIP-44 encrypted direct messages, and decentralized relay-based delivery. Current releases and source code are publicly available, so it is not merely a random closed app.
Is it “private-private”?
Potentially privacy-oriented, yes. Proven “trust it with your highest-risk communications” private, not yet.
Its strongest points are no compulsory phone number, no central chat cloud in the usual WhatsApp/Telegram sense, open source, and modern encrypted-message standards. But “no metadata” should be read as a design goal, not magic: relays and the networks carrying traffic can still potentially observe connection/IP and timing information unless you take separate network-level precautions. Device compromise, a malicious build, weak backup of keys/PIN, or a compromised contact are also outside the encryption promise.
The important gap is maturity: Vector is still beta, has a very small user base compared with the major apps, and I could not find a publicly documented independent security audit of the complete application. Open source is a positive, but it is not the same thing as a professional audit or years of hostile real-world testing.
Practical comparison
- Signal: Best default recommendation for genuinely sensitive one-to-one or group communications. End-to-end encryption is standard, the protocol and app have extensive security scrutiny, and Signal minimizes stored metadata. It still requires a phone number at registration, although you can use a username so contacts need not see it.
- Vector: More attractive than Signal if avoiding phone/email identity is a priority and you are comfortable with a beta Nostr-based app. The trade-off is much less independent review, less-established operational security, fewer users, and less certainty around reliability.
- WhatsApp: Personal messages and calls are end-to-end encrypted by default, which is materially better than many people assume. However, it is tied to a phone number and sits inside Meta’s broader ecosystem; account, device, contact and service metadata considerations remain. Good for everyday private chats where reach matters; not my first choice for anonymity or high-risk use.
- Telegram: Fine for communities, channels and reach, but ordinary Telegram chats are cloud chats, not end-to-end encrypted. Only manually created one-to-one Secret Chats are E2EE, and they do not sync across devices. Do not treat a normal Telegram DM or group as Signal-level private.
- WeChat/Weixin: The practical choice for communicating and doing daily life in mainland China, but not a privacy messenger. It is built for the China ecosystem, has broad platform integration, and should be assumed unsuitable for sensitive political, commercial-confidential, or anonymity-sensitive discussions.
Will Vector work in mainland China?
I would
not rely on it as a dependable no-VPN solution.
Vector’s decentralized Nostr architecture means it has no single central service to block, so it may work when the chosen relays are reachable. But that does not make it immune to the Great Firewall: relay domains/IPs, WebSocket traffic, app-download sites, and GitHub-hosted release access can all be disrupted or blocked selectively. I found no reliable current evidence that Vector has been consistently tested and maintained for mainland-China access.
Also, the practical issue starts before messaging: WhatsApp, Signal and Telegram were removed from Apple’s mainland-China App Store in April 2024, and access to those services remains unreliable or blocked. Vector is not a mainstream local-store option either; its own documentation still presents it as beta software, with Android/desktop availability and iOS not yet presented as a normal established release path.
Bottom line: Vector is worth watching and testing with non-sensitive chats if you like its no-phone-number, decentralized model. For serious private messaging today, I would choose
Signal. For mainland China, use
WeChat for ordinary local communication, but assume it is not private; do not depend on Vector, Signal, WhatsApp, or Telegram staying reachable without interruption or additional connectivity arrangements.
