Signal set the bar for end-to-end encrypted messaging. But depending on your threat model, you might want something that does not require a phone number, runs on a decentralized network, or offers better group features for teams.
We tested seven alternatives over the past month. Here is what actually works and what falls short.
Why look beyond Signal?
Signal is excellent, but three things push people to look elsewhere:
- Phone number requirement. Signal ties your identity to a phone number. For whistleblowers, journalists, or anyone wanting to avoid phone-based identity, that is a dealbreaker.
- Centralized servers. Signal runs on centralized infrastructure. If Signal’s servers go down (it has happened), so does your messaging.
- Limited group features. Signal groups work fine for friends and family, but lack channels, threads, and admin tools that teams need.
None of these are security flaws. They are trade-offs that different users weigh differently.
The alternatives
1. Session — best for anonymous messaging
Session strips out the phone number requirement entirely. You get a Session ID, no email or phone needed. Messages route through an onion network (similar to Tor), making metadata collection extremely difficult.
The downside: message delivery can be slower than Signal, and the desktop app feels rougher around the edges. File sharing caps at 10 MB.
Pricing: Free, open-source Platforms: iOS, Android, Windows, macOS, Linux
2. SimpleX Chat — best for metadata resistance
SimpleX goes further than any other messenger in preventing metadata leaks. There are no user identifiers at all, not even random ones. Each conversation uses separate messaging queues, so even the server operators cannot determine who is talking to whom.
Setup takes about two minutes. The app has improved significantly in 2026, with voice messages, groups, and file transfer all working reliably now.
Pricing: Free, open-source Platforms: iOS, Android, Windows, macOS, Linux
3. Element (Matrix) — best for communities and teams
Element runs on the Matrix protocol, which is federated. You can host your own server or use a public one. Rooms, spaces, threads, and bridges to other platforms (Slack, IRC, Discord) make it the most feature-rich option on this list.
The complexity is real though. Self-hosting Matrix is not trivial, and the default server (matrix.org) has had performance issues during traffic spikes.
Pricing: Free (self-hosted), Element Server Suite from $5/user/month Platforms: iOS, Android, Web, Windows, macOS, Linux
4. Briar — best for high-risk environments
Briar works without internet. It can sync messages over Tor, Wi-Fi, or even Bluetooth. Designed for activists and journalists in hostile environments where network access may be monitored or cut entirely.
The trade-off is severe: Android only, no iOS, no desktop, no media messages. Text and forums only. This is a tool for specific threat models, not a daily driver.
Pricing: Free, open-source Platforms: Android only
5. Wire — best for business use
Wire offers end-to-end encryption with a polished UI that works well for teams. Conference calls with up to 25 participants, screen sharing, and guest rooms for external contacts.
Wire changed ownership multiple times and moved its holding company to the US, which made some privacy advocates uncomfortable. The encryption is still solid, but the corporate governance story is less clear than it used to be.
Pricing: Free (personal), $7.65/user/month (business) Platforms: iOS, Android, Web, Windows, macOS, Linux
6. Threema — best for Swiss privacy jurisdiction

Threema is based in Switzerland, requires no phone number or email to register, and uses its own protocol for end-to-end encryption. You can verify contacts via QR code scanning.
It costs $5.99 one-time. That is unusual for a messenger app, and it means fewer people use it, which is the main practical problem. Threema is strong technically but has a smaller network.
Pricing: $5.99 one-time Platforms: iOS, Android, Web (companion)
7. XMPP with OMEMO — best for protocol purists
XMPP is the original open messaging protocol, and OMEMO adds modern end-to-end encryption. The appeal is full server choice, protocol-level federation, and client diversity.
The reality: setup requires picking a server and client, configuring OMEMO keys, and hoping your contacts do the same. Not for casual users.
Pricing: Free (varies by server) Platforms: Depends on client choice (available on all platforms)
How to pick
If you want Signal but without a phone number, get Session or Threema.
If you want maximum metadata protection, SimpleX is the clear leader.
If you need team features, Element or Wire depending on whether you want federation or simplicity.
If you are in a high-risk environment with unreliable internet, Briar is purpose-built for that.
For most people who just want good privacy for daily messaging, Signal remains the best overall option. These alternatives serve specific needs that Signal does not.
