Quick Comparison: Top Messaging Apps at a Glance

The 32 Best Messaging and Chatting Apps Reviewed

1. WhatsApp

WhatsApp is the most popular messaging app on the planet, with 3.3 billion monthly active users across 180+ countries. Owned by Meta, it offers free text and voice messages, photo and file sharing, and end-to-end encryption by default on all chats and calls. Group chats support up to 1,024 members, and Channels (launched in 2023) let businesses and creators broadcast to unlimited followers.

WhatsApp Business and the WhatsApp Business API make it a serious tool for customer communication. If you are exploring business integrations, see our guide on WhatsApp Business bot development. The desktop and web clients keep conversations synced across devices. Voice and video calls support up to 32 participants with screen sharing.

2. Facebook Messenger

Facebook Messenger has over 1 billion monthly active users and works on web, Android, and iOS. Originally part of Facebook, it became a standalone app in 2014 and has since evolved into a full communication platform. Users can send text, photos, videos, stickers, voice messages, and GIFs. Messenger also supports voice and video calls (including group calls up to 50 people), end-to-end encrypted conversations (enabled by default since late 2023), payment transfers, and chatbot integrations for businesses.

3. Telegram

Telegram crossed 1 billion monthly active users in 2025, making it one of the fastest-growing messaging apps ever. It is cloud-based, meaning messages sync across all your devices instantly. Telegram stands out with channels (unlimited subscribers), groups (up to 200,000 members), bots, and an open API that developers can build on. End-to-end encryption is available in Secret Chats, while standard chats use client-server encryption. Voice and video calls with screen sharing, file sharing up to 2GB, and a built-in Stories feature round out the feature set.

4. Signal

Signal is the gold standard for private messaging. Backed by the non-profit Signal Foundation, it offers end-to-end encryption by default on every message, call, and file transfer using the open-source Signal Protocol (the same protocol WhatsApp and Messenger license). After WhatsApp's 2021 privacy policy controversy, Signal saw a massive user surge. Features include disappearing messages, a built-in photo editor, dark theme, group chats up to 1,000, and voice/video calls. Signal collects virtually no metadata, making it the top choice for journalists, activists, and privacy-conscious users.

5. iMessage

iMessage is Apple's built-in messaging service, available on every iPhone, iPad, Mac, and Apple Watch. It provides end-to-end encryption by default, seamless sync across Apple devices via iCloud, and rich features including Tapback reactions, inline replies, SharePlay, and Digital Touch. Group chats support up to 32 people, and FaceTime integration means you can jump from a text to a video call in one tap. The main limitation is platform lock-in: iMessage only works natively within the Apple ecosystem. With iOS 18, Apple added RCS support for cross-platform texting with Android users.

6. Google Messages (RCS)

Google Messages is the default SMS/RCS app on most Android phones, with over 1 billion users. In 2026, RCS (Rich Communication Services) has matured into a full messaging protocol that rivals iMessage: read receipts, typing indicators, high-resolution photo/video sharing (up to 100MB), group chats, reactions, and end-to-end encryption via the MLS protocol. With Apple adopting RCS in iOS 18, cross-platform messaging between Android and iPhone finally has feature parity. Google Messages also includes AI-powered spam filtering that detects phishing links and scam attempts on-device.

7. WeChat

WeChat dominates in China with 1.38 billion monthly active users. It is far more than a messaging app: it is a super-app encompassing payments (WeChat Pay), mini-programs (apps within the app), social media (Moments), ride-hailing, food delivery, and government services. Messaging features include text, voice messages, video calls, location sharing, and group chats up to 500 members. For businesses looking to enter the Chinese market, WeChat is not optional, it is essential.

8. Snapchat

Snapchat has over 900 million monthly active users and remains hugely popular with younger demographics (ages 13 to 34). Its defining feature is ephemeral content: Snaps disappear after viewing, and Stories vanish after 24 hours. Beyond disappearing messages, Snapchat offers a powerful AR camera with thousands of filters and lenses, Snap Map for location sharing, Spotlight for short-form video, and voice/video calls. The Snapchat+ subscription adds extra features like custom app icons and story re-watch indicators.

9. Discord

Discord started as a gaming communication tool but has evolved into a general-purpose community platform with over 200 million monthly active users. It supports text channels, voice channels (always-on voice rooms), video calls, screen sharing, and streaming. Servers can have unlimited members with granular role and permission systems. Bot integrations extend functionality endlessly. Discord Nitro ($9.99/month) adds higher upload limits, custom emojis everywhere, and HD streaming. If you are building a community-driven app, Discord's architecture is worth studying.

10. Microsoft Teams

Microsoft Teams has over 320 million monthly active users and is the dominant messaging and collaboration tool in enterprise. It integrates directly with the Microsoft 365 suite: Word, Excel, PowerPoint, SharePoint, and OneDrive. Features include persistent chat, threaded channels, voice and video calls (up to 1,000 participants for calls, 10,000 for view-only meetings), file co-editing, and extensive third-party app integrations. Teams is free for personal use, with paid plans for business starting at $4/user/month.

11. Slack

Slack is the premier messaging app for workgroups and engineering teams. It organizes conversations into channels by topic, project, or team. Features include threaded messages, file sharing, voice/video huddles, screen sharing, searchable message history, and over 2,600 app integrations (Jira, GitHub, Google Drive, etc.). Slack Connect lets you message people in other organizations. The free tier supports up to 90 days of message history, while paid plans ($7.25+/user/month) unlock unlimited history and advanced features.

12. Viber

Viber has 260+ million monthly active users and is particularly popular in Eastern Europe, the Middle East, and Southeast Asia. It offers end-to-end encryption by default on all personal chats and calls. Standout features include Viber Out (low-cost calls to landlines and mobiles), Communities (up to 1 billion members), a rich sticker marketplace, disappearing messages, and cross-device syncing. Viber for Business offers chatbots and promotional messages for brands.

13. LINE

LINE is the dominant messaging app in Japan, Taiwan, and Thailand with 196+ million monthly active users. It offers free messaging, voice and video calls, a massive sticker store, a social feed (Timeline), and LINE Pay for mobile payments. LINE also supports mini-apps, games, and news, positioning it as a super-app in its core markets. End-to-end encryption (called Letter Sealing) is on by default. For businesses, LINE Official Accounts provide customer communication channels.

14. KakaoTalk

KakaoTalk is South Korea's dominant messaging platform, used by over 93% of the country's smartphone users. It supports free text, voice calls, and video calls with unlimited participants. Features include group chats, file sharing (up to 300MB from PC), a rich emoticon/sticker store, live streaming, and KakaoPay for mobile payments. Like WeChat in China and LINE in Japan, KakaoTalk has evolved into a broader platform with services including taxi-hailing, shopping, and banking.

15. Threema

Threema is a paid ($5.99, one-time) messaging app built for maximum privacy. Based in Switzerland, it does not require a phone number or email to register. Instead, users get a random Threema ID. All messages, calls, and files are end-to-end encrypted. Even Threema's own servers cannot read your messages. It supports text, voice messages, voice and video calls, polls, file sharing, and group chats up to 256 members. Threema Work is the enterprise version with admin controls and device management.

16. Wire

Wire is a secure messaging app designed by Janus Friis, co-founder of Skype. It offers end-to-end encryption for messages, voice calls, video calls, and file sharing. Wire supports 1:1 and group screen sharing, timed (self-destructing) messages, and works across all platforms including a web client. Registration requires a phone number or email, but neither is shared with other users. Wire for Enterprise targets regulated industries like finance, government, and healthcare.

17. Element (Matrix)

Element (formerly Riot) is the flagship client for the Matrix open-standard protocol. It supports end-to-end encrypted messaging, voice calls, video calls, file sharing, and bridges to other platforms (Slack, IRC, Discord, Telegram). The killer feature is self-hosting: organizations can run their own Matrix server for complete data sovereignty. The French government, German military, and Mozilla all use Matrix-based communication. Element is free and open-source.

18. Session

Session is a privacy-focused messenger that requires no phone number, no email, and collects no metadata. Messages are routed through a decentralized onion-routing network (similar to Tor), making it extremely difficult to trace who is talking to whom. It supports text, voice messages, file attachments, and group chats up to 100 members. Session is open-source and free. The trade-off for this level of privacy is that it does not yet support voice or video calls and can be slower than centralized alternatives.

19. Briar

Briar is designed for activists, journalists, and anyone who needs to communicate even when the internet is down. It can sync messages over Tor, Wi-Fi, or Bluetooth, meaning two users in close proximity can message without any internet connection. All messages are stored on-device (never on a server) and are end-to-end encrypted. Briar supports text messaging, forums, and blogs. It is Android-only and deliberately minimal, prioritizing security and resilience over convenience.

20. Skype

Skype was one of the original VoIP messaging apps, launched in 2003 and now owned by Microsoft. It supports instant messaging, voice calls, video calls (up to 100 participants), screen sharing, and file transfers across desktop, mobile, and web. Skype-to-Skype calls are free; calls to landlines and mobile numbers use a credit system. While Teams has overtaken it in enterprise, Skype remains popular for personal international calls and has recently been updated with a refreshed interface and Copilot AI integration.

21. Zoom Chat

Zoom is best known for video meetings, but Zoom Chat (formerly Zoom Team Chat) is a full messaging platform. It supports persistent 1:1 and group chats, channels, file sharing, screen sharing, whiteboarding, and integrations with third-party apps. The advantage is seamless escalation from a chat message to a Zoom meeting or phone call with one click. Zoom's free plan supports 40-minute group meetings and unlimited 1:1 calls.

22. Voxer

Voxer is a walkie-talkie-style push-to-talk (PTT) messenger designed for fast voice communication. In addition to PTT voice, you can send text messages, photos, and share your GPS location. Messages can be played back in real time or listened to later, like a voice-message inbox. Voxer Business ($6.25/month per user) adds admin controls, unlimited message history, and is popular with logistics, hospitality, and field service teams.

23. GroupMe

GroupMe is a Microsoft-owned group messaging app. You can create groups of up to 500 members, share photos, videos, locations, and create polls. Each group gets a unique phone number so people without the app can participate via SMS. GroupMe is particularly popular on US college campuses and for event coordination. It is free with no paid tier.

24. Dust (formerly Cyber Dust)

Dust is a privacy-focused messaging app where messages auto-delete within 24 hours (or 100 seconds after being read). It does not store any messages on its servers once they are delivered. Screenshots are detected and the sender is notified. Dust supports text, photos, and videos but not voice or video calls. It is aimed at users who want Snapchat-level ephemerality with stronger privacy guarantees.

25. Wickr Me

Wickr Me (now part of AWS Wickr after Amazon's acquisition) offers end-to-end encrypted messaging with configurable message expiration timers. It supports text, voice messages, voice calls, video calls, file sharing, and screen sharing. AWS Wickr targets enterprise and government clients with features like compliance retention, admin controls, and federation. It is available on iOS, Android, macOS, Windows, and Linux.

26. Rocket.Chat

Rocket.Chat is an open-source team communication platform that can be self-hosted or used as a cloud service. It supports real-time messaging, voice and video calls, file sharing, and integrations with hundreds of apps. Key differentiators include federation (Rocket.Chat servers can communicate with each other), omnichannel customer engagement (WhatsApp, email, and chat in one inbox), and full data ownership. It is a strong Slack alternative for organizations that need on-premise deployment.

27. Mattermost

Mattermost is another open-source, self-hosted messaging platform aimed at developers and DevOps teams. It offers persistent channels, threaded messaging, code snippet sharing with syntax highlighting, integrations with CI/CD tools (Jenkins, GitLab, GitHub), and playbooks for incident management. Mattermost is popular with organizations that require data sovereignty and cannot use cloud-hosted tools like Slack or Teams.

28. Tango

Tango is a multiplatform messaging app developed by TangoME, Inc. The free app supports video calls, voice calls, text messages, photo sharing, and games. Available in 14 languages including Arabic, Chinese, and Turkish, Tango has a user base of 160+ million registered users. It is straightforward and lightweight, making it popular in regions with slower internet connections.

29. IM+

IM+ is an all-in-one messaging aggregator that combines chat histories from Facebook Messenger, Instagram, Skype, Telegram, Twitter, and more into a single interface. Instead of switching between 5 different apps, IM+ puts all your conversations in one place. It saves storage space and reduces notification fatigue. Currently available for iOS and macOS.

30. Google Chat

Google Chat (the successor to Google Hangouts) is a messaging platform integrated with Google Workspace. It supports direct messages, group conversations, and Spaces (persistent rooms for teams). Integration with Google Docs, Sheets, and Meet makes it seamless for teams already in the Google ecosystem. Google Chat is free with a personal Google account and included in all Workspace plans.

31. Zalo

Zalo is the most popular messaging app in Vietnam with over 75 million users. It supports text, voice, and video messages, group chats up to 1,000 members, file sharing (up to 1GB), and a social feed (Diary). Zalo also offers ZaloPay for mobile payments and Zalo Official Accounts for businesses. If you are building or expanding products for the Vietnamese market, Zalo integration is essential.

32. Zangi

Zangi is a secure messaging app optimized for low-bandwidth and unstable internet connections. It uses proprietary compression technology that makes voice and video calls usable even on 2G networks. Zangi offers end-to-end encryption, does not store messages on servers, and does not require a phone number for registration. It is aimed at users in regions with poor network infrastructure.

Best Apps for Voice and Video Calling

Many users search for apps that combine messaging with high-quality voice and video calls. Here is how the top messaging apps compare on calling features:

For personal video calls, WhatsApp and FaceTime offer the best combination of quality and encryption. For large-scale meetings, Zoom and Microsoft Teams dominate. For privacy-first calling, Signal and Wire are the top choices. If you are building a cross-platform app with real-time voice or video, WebRTC is the standard protocol to use, typically paired with a progressive web app for browser-based access.

Best Alternatives to WhatsApp

WhatsApp is the default messaging app in most countries, but there are strong reasons to look elsewhere: privacy concerns (Meta collects metadata), platform fatigue, or specific features WhatsApp lacks. Here are the top alternatives by use case:

Best for Privacy: Signal

Signal offers the same end-to-end encryption as WhatsApp (WhatsApp actually licenses the Signal Protocol) but collects virtually no metadata. It is run by a non-profit foundation with no advertising or data monetization. Signal is the recommended WhatsApp alternative for anyone who prioritizes privacy above all else.

Best for Features: Telegram

Telegram offers features WhatsApp does not: channels with unlimited subscribers, groups up to 200,000 members, bots, 2GB file sharing, username-based contact (no phone number needed to chat), and a fully open API. The trade-off is that standard chats are not end-to-end encrypted, only Secret Chats are.

Best for Business Teams: Slack or Microsoft Teams

If you are replacing WhatsApp groups used for work, Slack and Teams provide structured channels, searchable history, app integrations, and proper admin controls that WhatsApp groups lack.

Best for Maximum Privacy: Threema or Session

Both apps can be used without providing a phone number. Threema is a one-time paid app based in Switzerland. Session routes messages through an onion network and collects zero metadata. If you need anonymity, not just encryption, these are your options.

Best for Apple Users: iMessage

If everyone in your circle uses Apple devices, iMessage is the most seamless alternative: it is built into every iPhone, encrypted by default, and syncs across Mac, iPad, and Apple Watch without installing anything.

Best Alternatives to Telegram

Telegram's large groups, channels, and bots make it unique, but its non-default encryption and content moderation issues push some users elsewhere. Here are the best alternatives depending on what you use Telegram for:

For Encrypted Group Chat: Signal

Signal now supports groups up to 1,000 members with full end-to-end encryption on every message. If your primary concern with Telegram is that standard chats are not E2E encrypted, Signal solves that.

For Communities and Servers: Discord

Discord's server model with multiple channels, roles, bots, and always-on voice rooms provides a richer community experience than Telegram groups. It is the best alternative for community builders and content creators.

For Open-Source Self-Hosting: Element (Matrix)

If you value Telegram's open API but want full data control, Matrix/Element lets you run your own server. It also bridges to Telegram, Slack, and IRC, so you can keep your existing contacts.

For Developer Teams: Rocket.Chat or Mattermost

Both are open-source, self-hosted alternatives with integrations for CI/CD tools, code review, and incident management. If you are using Telegram groups for engineering coordination, these are purpose-built alternatives.

What Makes a Great Messaging App in 2026

After reviewing 32 of the best messaging apps and building real-time chat applications for clients across industries, certain patterns define the apps that win:

• End-to-end encryption by default — users now expect privacy as a baseline, not an opt-in setting
• Cross-platform parity — identical experience across iOS, Android, web, and desktop (see our cross-platform framework comparison for the technical choices)
• Low-latency delivery — real-time WebSocket infrastructure is non-negotiable for chat
• Rich media support — photos, videos, voice messages, files, and reactions drive daily engagement
• Reliable push notifications — delivery across platforms (APNs, FCM) keeps users coming back
• Group and community features — channels, rooms, threads, and moderation tools drive retention
• AI-powered features — smart replies, message translation, and spam filtering are becoming table stakes in 2026
• Interoperability — RCS adoption and Matrix federation are pushing messaging toward open standards

Whether you are launching a new communication tool or building a social media app with messaging features, understanding the competitive landscape is the first step to building something that wins. The most successful messaging products combine a clear privacy stance, cross-platform reliability, and at least one feature that is meaningfully better than the incumbents.

Frequently Asked Questions

What is the most secure messaging app in 2026?

Signal is widely considered the most secure mainstream messaging app. It uses the Signal Protocol for end-to-end encryption by default, is open-source, and collects virtually no user metadata. For even stronger anonymity (no phone number required, onion routing), Session and Briar are worth considering, though they have smaller user bases and fewer features.

Which messaging app is best for video calling?

For personal video calls, WhatsApp and FaceTime offer the best combination of quality and encryption. For large group calls and business meetings, Zoom (up to 1,000 participants) and Microsoft Teams lead. For privacy-first video calling, Signal supports encrypted group video calls with up to 40 participants.

What is the best alternative to WhatsApp?

It depends on your priority. For privacy, choose Signal. For features and large groups, choose Telegram. For Apple-only groups, iMessage works seamlessly. For workplace communication, Slack or Microsoft Teams provide structure that WhatsApp groups lack. For maximum anonymity, Threema or Session let you chat without providing a phone number.

Are messaging apps free to use?

Most messaging apps are free for personal use, including WhatsApp, Telegram, Signal, Discord, and Messenger. Some apps charge for business or premium features: Slack and Teams have paid tiers for organizations, Threema charges a one-time fee of $5.99, and Discord Nitro costs $9.99/month for cosmetic and feature upgrades. Voxer Business costs $6.25/month per user.

Which messaging app has the largest groups?

Telegram leads with groups supporting up to 200,000 members and channels with unlimited subscribers. Discord servers have no hard member cap. Viber Communities support up to 1 billion members. WhatsApp groups cap at 1,024 members, while Signal supports up to 1,000.

Can I use messaging apps without giving my phone number?

Yes. Threema, Session, Briar, and Element/Matrix all allow registration without a phone number. Threema assigns a random ID, Session generates a Session ID, and Matrix lets you create a username on any server. Most mainstream apps (WhatsApp, Telegram, Signal) still require a phone number for registration.

What messaging app works best on slow internet?

Telegram is optimized for slow connections and works well on 2G/3G networks. Zangi uses proprietary compression to make voice and video calls usable on extremely slow connections. Briar can work with no internet at all, syncing via Bluetooth or Wi-Fi. For text-only messaging, most apps handle slow connections reasonably well since text messages are tiny.

How do I build my own messaging app?

Building a messaging app requires real-time infrastructure (WebSockets or a service like Firebase Cloud Messaging), a backend for user authentication and message storage, push notification integration (APNs for iOS, FCM for Android), and end-to-end encryption. Most teams use cross-platform frameworks like React Native or Flutter to ship on both iOS and Android from a single codebase. For a detailed walkthrough, read our guide on how to build a social media app.
