Best WhatsApp alternatives in 2021

by Emma

WhatsApp’s May 15 deadline for accepting its controversial privacy policy update is upon us, and the deal is simple – take it or risk losing core functionalities that will effectively make the app useless for you. The Facebook-owned company assures that nothing is changing for your personal or group conversations as they remain end-to-encrypted. Still, if you chat with a business account, your data will be shared that Facebook will use for advertising. Despite all that, WhatsApp has actually been sharing data with Facebook for a while now. If you’re someone familiar with Facebook’s poor track record over privacy and fear that the same fate might befall WhatsApp too, it’s time to look for alternatives. And to save you the trouble, we’ve rounded up this list of the best WhatsApp alternatives in 2021:

Signal

WhatsApp

If privacy is your top priority, then Signal is one of the best options out there. An app that has been advertised by people like Edward Snowden (privacy advocate and former CIA employee), Twitter CEO Jack Dorsey, journalists, and cybersecurity experts across the globe, Signal should be at the top of your list if you’re planning to leave WhatsApp for a more secure option. Here’s an interesting fact – even WhatsApp’s encryption has Signal Protocol as the underlying technology.

The Signal is free, and more importantly, it is open source. This means that anyone, especially security experts, can look into its codebase for vulnerabilities and security flaws, ensuring no hidden backdoors or leaks. All your information and communication data are encrypted, even the stickers you share. Aside from text-based messages, you can also make voice and video calls and communicate via group chats. A few privacy-focused add-ons include screenshot-blocking and self-destructing statements. 

Signal promises that there are no ads, affiliate marketing parties, or any form of user tracking. Another assurance is that Signal is an independent non-profit and is not owned by another major tech company – unlike the WhatsApp and Facebook bond – and is unlikely to budge under pressure and change its commitment towards privacy.

The service recently made it easier to migrate your data to another device (iOS and Android) and added some new features to make the switch from WhatsApp more palatable. And oh, it uses a strict PIN system for signing in. It is even testing peer-to-peer payments services involving cryptocurrencies. Another considerable advantage is using it across Android, iOS, Windows, macOS, and Linux ecosystems.

Telegram

If you’re still holding tightly to your WhatsApp account because the rivals might not have those features, Telegram is your answer. Telegram is free, just like WhatsApp, but offers a lot more features. For example, you can create group conversations (or channels) with up to 200,000 participants and send files of up to 2GB without a fuss. And if you’re worried about expressing yourself, there are a ton of awesome animated stickers (and even the ability to create custom ones) that I absolutely love. 

Now, let’s talk about privacy. Like Signal, Telegram is also open source, which means anyone can independently verify the code for any security flaws. But there’s a slight caveat here. Only ‘secret chats’ are end-to-end encrypted, and they have to be enabled manually, but the regular chats are not. However, it allows you to hide your phone number by assigning you a t.me/XYZ username. So, even if you’re chatting with another person, they won’t know your phone number if you haven’t allowed it from the privacy settings.

Aside from the usual chat feature, you can conduct group voice calls (even in a live voice channel, somewhat like Clubhouse), schedule messages and even voice chats, video calls (group video calls are coming soon too), the ability to use multiple accounts (different phone numbers) in the same app (both mobile and desktop) and web client too, proximity alerts, and a lot more. Plus, you can also edit messages and even media files after sending them. 

Telegram also allows you to create separate chat folders, and they really come in handy if you want to keep your personal and work conversations separate. Then there are Telegram bots that can do anything from sending weather information or valuable news articles, schedule reminders, play music, create to-do lists, among other tasks. Telegram recently added a new feature that allows you to move your data from WhatsApp with ease. All your communications are synced across all devices and platforms (iOS, Android, macOS, Windows, and Linux), which I absolutely love.

Keybase

If you’re going all-in on the privacy aspect, Keybase is where you should look at. The app supports end-to-end encryption for all your conversations and even encrypts the files you share. Additionally, it allows you to communicate with other people without revealing your phone number or email address. Plus, multi-device support allows all your data to be transferred and synced with a layer of encryption on top. 

Keybase is open-source, and just like Telegram and Signal, anyone can take a look into the code at any given time to assess the security measures and check for any security flaws. Keybase says that it uses public-key cryptography for privacy. Additionally, it allows you to connect and communicate with people using their social media aliases from platforms such as Twitter and Reddit. Oh, and did I tell you about self-destructing messages? Keybase calls them ‘Exploding’ messages. 

The service lets you link a Stellar account – the open-source, decentralized protocol for sending money and engaging in cryptocurrency trading. Keybase actually supports syncing Stellar keys as well, aside from the ability to export a private key. You can also import an existing mailing list on Keybase and also invite anyone from your contacts. The app also has a group (or teams) feature as well. Keybase is available on Android, iOS, macOS, Windows and even has a native Linux client.

Threema 

Another app that takes privacy a tad too seriously is Threema. Let’s start with the basic features first. Three is an open-source platform that supports end-to-end encryption for messages and voice and video calls. Even your status updates are protected behind a wall of encryption. The company behind that app claims that all data is stored on your device, and none of it is stored on remote servers. All local files shared via Threema are encrypted on-device, and there is support for self-destructing messages too. 

Threema has a well-optimized tablet interface, and the web app also works well without cutting down on any features available in the mobile app. An interesting agree/disagree feature allows you to respond to a message without triggering a push notification on the recipient’s device. Private chats are protected behind a layer of PIN/password, and incoming messages for such conversations do not show the message preview. It also allows you to create polls, something not many messaging apps offers. 

Threema also lets you create an anonymous, encrypted backup of your contacts, groups, settings, and selected data that you can also transfer to another device when switching platforms. You can add formatting (bold, italic, strikethrough) to your text messages and even pin a chat. More importantly, Threema does not rely on a phone number. Instead, it generates a unique 8-digit ID for each user, allowing you to use the service without sharing identifiable information. 

The service relies on a critical system – actually two keys – the public key is stored on servers, while the private key is exclusive to your device’s storage. All messages sent to you can only be decrypted with this private key on your device. There is also a QR Code scanning feature in place that allows you to add a contact with Level 3 verification, ensuring that you’re not targeted by a man-in-the-middle attack.

Discord 

Discord is no longer a platform that is only targeted at gamers. In fact, I’ve even used it as the primary workspace communication platform in the past. Starting with the communication aspect, you can share text messages, GIFs, emotes, and even documents, in addition to conducting voice and video calls. What I really like about Discord is the integration with services such as Spotify, Twitch, YouTube, Steam, Reddit, Facebook, and Twitter, to name a few. The topic-based channels are a great way to explore content that will suit your interests. 

A remarkable aspect is the server-based system of Discord, which takes an invite-only approach for chatting with friends and interacting with community members. Screen-sharing is another cool feature that makes Discord useful for both sharing your game achievements and work progress. Additionally, you can assign Roles, create moderators, and even create working groups that act as channels for broadcasting a message. 

Unlike WhatsApp, though, you’re not required to share your phone number and can go with any random username to protect your identity. It is available as both mobile and desktop apps, and there’s a web-based client, too, with all the core functionalities intact. And suppose you jump to the paid Discord Nitro tier. In that case, you get a ton of extras such as the ability to create animated avatars, make customs, a higher file-size limit for sharing content, and the ability to stream in 4K resolution as well.

Final words

And with that, we conclude our best WhatsApp alternatives for the 2021 guide. While saying goodbye to WhatsApp is technically not too big of trouble, it can limit your scope of communication with those who rely on it for most of their communications. Pocketnow’s Editor-in-Chief Anton D. Nagy found it the hard way as he went ahead and deleted his WhatsApp account (and from all other Facebook-owned platforms, too), as not many people necessarily use the same alternative communication platform as him (me or you). My colleague Adam Z. Lein argues that even these alternative platforms are not as secure as they look right now. If history is any indication, you should stop being naive when pledging your loyalty to any of these communication platforms.
