Signal is an encrypted messaging app that uses the Signal Protocol, an open standard for end-to-end encryption. It's built by the Signal Foundation and run as a non-profit. Users include privacy-conscious individuals, journalists, activists, and organizations that require encrypted communication. The app works on iOS, Android, and desktop, and focuses on the core function of secure one-to-one and group messaging without ads or data collection.
People reach for Signal when they need assurance that their messages can't be read by the platform, their network provider, or law enforcement without access to their device. It's used for sensitive conversations where the stakes of interception or surveillance are high. Some teams rely on it for internal communication; others use it as their primary messenger because they object to how commercial messaging platforms handle user data. The typical Signal user values privacy as non-negotiable rather than as a feature to toggle on demand.

What to look for
- Whether the service collects IP addresses, message timestamps, or user metadata on its servers
- Whether you can register without providing a phone number or email address to the platform
- Whether the underlying encryption protocol is open-source and independently audited by cryptography researchers
- Whether the service can be self-hosted on your own infrastructure or run on community-controlled servers
- Whether the app supports encrypted voice and video calls, and the minimum network bandwidth required for calls
- Whether the app works on all platforms your team uses (iOS, Android, desktop, or web-only)
FAQ
What are the best alternatives to Signal?
The main open alternatives include Briar, Wire, and Riot.im, each with different trade-offs around platform availability and underlying protocols. Briar works over peer-to-peer mesh networks without relying on servers. Wire offers more enterprise controls. Riot.im (now Element) uses the Matrix protocol and allows decentralized deployments. The choice depends on whether you prioritize single-app simplicity or additional features like voice calls or group administration tools.
Are there free alternatives to Signal?
Signal is free, and its open-source alternatives—Briar, Wire, and Element—are also free. WhatsApp and Telegram have free tiers that support end-to-end encryption, though Signal and the open-source options don't collect metadata or require a phone number monetization model. Most alternatives offer the core encrypted messaging without a paid tier.
Which platforms do Signal alternatives support?
Most alternatives support iOS and Android. Signal, Wire, and Element have desktop clients. Briar relies more heavily on mobile right now. If your team spans desktop and mobile use, verify that any alternative you're evaluating offers native apps for each platform rather than web-only versions.
How do I choose an encrypted messaging app for my team?
Start by identifying your platform requirements—iOS, Android, desktop, or all three. Then check whether the app requires a phone number or email to register, since some teams prefer email-based identity. Finally, confirm whether the underlying protocol is open-source and audited by third parties, and whether the service can be self-hosted if your compliance rules demand it.
Can I self-host an alternative to Signal?
Signal's infrastructure requires their servers, but Wire, Element, and Briar can be self-hosted or run on community infrastructure. If regulatory compliance or data residency requirements apply to your organization, self-hosting capability is a make-or-break feature. Check the product's documentation for deployment guides and hardware requirements before committing.
Do encrypted messaging alternatives support group calls and voice messaging?
Signal, Wire, and Element all support encrypted group voice and video calls. Briar is lighter-weight and focuses on text and file sharing. WhatsApp and Telegram also support calls but route metadata through their servers. If calls are essential, test the voice quality and reliability on your network before rolling out to a larger team.
What's the difference between open-source and open-protocol messaging?
Open-source means the code is published and auditable, but the service might still be centralized. Open-protocol means the encryption standard itself is public and non-proprietary (like Signal's protocol). Signal is open-protocol but not open-source software. Briar and Element are both open-source and open-protocol. This distinction matters if you want to verify security claims or deploy on your own infrastructure.
Are there messaging apps with better metadata privacy than Signal?
Briar collects no metadata because it's peer-to-peer and doesn't rely on servers. Wire minimizes metadata collection but still runs centralized servers. Signal collects timestamps and IP addresses on their server logs. If metadata privacy is your top concern, Briar or a self-hosted Element instance offer stronger guarantees than Signal's server-based model.
