How Signal Compares to Other Open Source Messengers
If you’re diving into the world of open source messengers, you’ve probably heard of Signal — but how does it really stack up against other options? As someone who’s been using Signal daily for years, I’m here to break down how Signal compares to other popular open source messengers like Element (Matrix), Wire, and Telegram (which is partially open source). I'll share some practical tips and quirks I’ve learned along the way, so you get a clear picture of what to expect.
Why Choose an Open Source Messenger?
Before we dig into the comparison, let's quickly remind why open source matters. Open source messengers let anyone review their code, which builds trust around privacy and security claims. Unlike proprietary apps, you’re less likely to run into hidden backdoors or shady data collection. Signal, for example, makes its code publicly available on signal.org and GitHub, which means security researchers constantly check their work.
That said, simply being open source isn’t enough — user experience, features, and real-world security also count. That's where Signal really shines compared to many other open source alternatives.
How Signal Compares to Other Popular Open Source Messengers
1. Security and Privacy
- Signal: Uses the Signal Protocol, widely regarded as the gold standard for end-to-end encryption (E2EE). It encrypts everything — messages, voice/video calls, group chats, even metadata to some extent. Signal also minimizes data collection: it only stores your phone number and the last connection date on its servers, nothing else.
- Element (Matrix): Also supports E2EE with the Olm and Megolm protocols, but encryption can be a bit trickier to manage, especially in larger groups. Because Matrix is decentralized (you can run your own server), trust depends somewhat on your chosen server.
- Wire: Offers E2EE and is open source, but it’s also a commercial product owned by a company that may collect metadata. Security is solid, but some users prefer Signal’s minimal data approach.
- Telegram: Uses server-client encryption by default, but E2EE only in “secret chats.” Telegram’s code is partially open source, which raises some trust questions.
If your top priority is airtight security and minimal data collection, Signal is tough to beat.
2. User Experience and Features
- Signal: The interface is straightforward, clean, and fast. It offers disappearing messages, typing indicators, reactions, stickers, and even encrypted group calls. One cool feature I've come to rely on is the ability to blur faces in photos directly inside the app — super useful when sharing images without compromising others’ privacy.
- Element: Feature-rich with support for rooms, threads, and integrations, but it can feel overwhelming if you just want simple chatting. It’s more suited for teams or communities.
- Wire: Polished UI with multimedia support and business-oriented features like guest rooms. Good for professional use.
- Telegram: Packed with features like channels, bots, and massive groups. It’s very fast but less privacy-focused by default.
In my experience, Signal strikes a nice balance between simplicity and enough features for everyday use.
3. Cross-Platform Support
Signal supports iOS, Android, Windows, macOS, and Linux with dedicated apps. The desktop app syncs seamlessly with your phone, requiring you to link it through a QR code, which is an extra security step I appreciate.
Element is also cross-platform but sometimes feels a bit heavier, especially on desktop. Wire supports multiple platforms too, but some users complain about performance issues. Telegram’s apps are lightning-fast and available everywhere, but again, with less privacy by default.
4. Account Setup and Identity
Signal uses your phone number as your identity, which might feel limiting if you want anonymous chatting. However, the upside is that contact discovery works smoothly without uploading your entire address book to their servers — it uses a clever cryptographic process to match contacts without revealing your data.
On the other hand, Element lets you create usernames without phone numbers, which is great for anonymity or multi-device use without a smartphone. Wire and Telegram also support usernames, giving more flexibility.
Personally, I’ve found Signal’s phone number system to be a reasonable trade-off for privacy and ease of use. Just remember to enable registration lock PIN in settings to add an extra layer of security against hijacking your number.
Practical Tips for Using Signal Like a Pro
Now, here are a few practical Signal tips that aren’t obvious to newbies but make a big difference:
- Enable disappearing messages by default: You can set disappearing messages to always be on for new chats under Settings > Privacy > Disappearing messages. This helps keep conversations clutter-free and private automatically.
- Use the “Note to Self” chat: This is a handy built-in chat where you can quickly save links, reminders, or files. I use it daily instead of separate note apps.
- Blur faces or sensitive info in photos: When sending images, tap the pencil icon and choose the blur tool. It’s a neat way to respect privacy without extra editing apps.
- Backup wisely: Signal doesn’t store your chat history on servers — so make local encrypted backups if you switch devices. On Android, you can create encrypted backups in Settings > Chats > Chat backups. On iOS, rely on iCloud backups, but be aware of Apple’s limitations.
- Pin important chats: Long-press a conversation and tap “Pin” so your frequent contacts never get lost in the mix.
- Manage who can add you to groups: Go to Settings > Privacy > Groups and restrict who can add you, to avoid spammy group invites.
Some Minor Quirks to Keep in Mind
Like any app, Signal has a couple of quirks I’ve learned to work around:
- When switching devices, you can only transfer your profile and contacts once. After that, you need to set up Signal fresh
