Slack

Slackbot just picked up Salesforce record previews, live Tableau charts, and DocuSign envelope actions inside DMs. That is genuinely useful for sales teams. It is also more paid-tier surface area, another set of admin controls, and one more reason budget owners look at the Slack renewal and start asking what else runs. If you are the person opening Slack on your phone twenty times a day and the answer to “why are we still on this” keeps getting weaker, the Slack alternatives shortlist for Android in 2026 is stronger than the marketing tries to imply.

The 7 best Slack alternatives on Android

Microsoft Teams, best for Microsoft 365 workplaces

Microsoft Teams is the default answer for anyone already paying for Microsoft 365. Chat, channels, meetings, calling, and file sharing all live in one Android app, and the Copilot side panel now summarizes threads and drafts replies without leaving the conversation. Push notifications and thread muting were rebuilt in 2025 and finally feel comparable to Slack’s.

Where it falls short: The mobile client still opens slowly on cold start, and the “activity feed” mixes reactions, mentions, and channel updates in a way Slack keeps cleanly separated. Third-party integrations are catching up but still lag Slack’s App Directory.

Pricing:

Migrating from Slack: Microsoft’s Migration Manager imports Slack channels, DMs, files, and history via Slack’s export tool. Custom emoji move, integrations do not.

Download: Google Play

Bottom line: The right default for any team already on Microsoft 365.

Discord, best for small teams and communities

Discord started as gaming chat and grew into a serious workplace tool for small studios, agencies, and open-source projects. Persistent voice channels change how teams actually talk during the day, one click into a room instead of scheduling a call. The Android app is fast, notifications are configurable per channel, and threads work well for async conversations.

Where it falls short: No native integration for enterprise directories or SCIM, so onboarding and offboarding at scale needs manual work. Message retention has no legal-hold controls, which rules it out for regulated industries.

Pricing:

Migrating from Slack: No official importer. Communities usually rebuild channel structure by hand, which is fast for teams under 30 people.

Download: Google Play

Bottom line: Pick Discord if you are under 50 people and voice-first conversations would help more than another chat app.

Element, best for encrypted federated chat

Element runs on the Matrix protocol, which means end-to-end encrypted DMs and channels, cross-server federation, and no single company holding your data. The Android app supports encrypted voice and video calls and works across Element’s hosted service or your own Matrix homeserver.

Where it falls short: Federation is powerful but adds moving parts. First-time users trip on key backup and cross-signing. UI polish still lags Slack, especially threaded conversations that get long.

Pricing:

Migrating from Slack: Matrix maintains a Slack bridge that mirrors channels and DMs into an Element workspace. The bridge is one-way friendly but full migration is a rebuild.

Download: Google Play

Bottom line: The right pick when the threat model says the chat provider must not read your messages.

Rocket.Chat, best for self-hosted collaboration

Rocket.Chat is the mature open-source Slack clone that a lot of enterprises quietly run inside their own perimeter. Channels, DMs, threads, huddles, and voice calls all work the way Slack users expect, and the Android app supports both cloud and self-hosted deployments through workspace URLs.

Where it falls short: Self-hosting means someone in the team has to run and update the server. Cloud plans are competitive but drop the biggest reason to pick Rocket.Chat in the first place. Search on very large workspaces stays a rough edge.

Pricing:

Migrating from Slack: Native Slack importer parses the standard Slack export ZIP and rebuilds channels, users, and messages.

Download: Google Play

Bottom line: The default choice when the team has to own the chat server.

Mattermost, best for DevOps and regulated teams

Mattermost is the chat platform DevOps and government teams choose when Slack is off the table. Playbooks turn recurring incidents into checklists that run inside a channel, and the mobile app supports incident response as a first-class flow, not an afterthought.

Where it falls short: UI feels more utilitarian than Slack. Casual users describe it as “Slack from three years ago”, which is a fair read. The paid cloud tier is priced higher than most alternatives here.

Pricing:

Migrating from Slack: Mattermost ships a Slack import tool that reads the Slack export ZIP.

Download: Google Play

Bottom line: Pick Mattermost when incident response and audit trails matter more than polish.

Zulip, best for thread-heavy async teams

Zulip organizes every conversation by topic inside a stream, so a channel with hundreds of threads stays scannable instead of collapsing into a wall of interleaved messages. Async and distributed teams tend to convert after a week of use because the mental overhead of “which thread am I in” drops sharply.

Where it falls short: The topic model has a learning curve that not every team gets over. Voice and video are basic and rely on integrations. UI is dense.

Pricing:

Migrating from Slack: Zulip’s Slack importer moves users, channels, messages, files, and custom emoji.

Download: Google Play

Bottom line: The right pick if your team lives in threads and hates losing them.

Google Chat, best for Google Workspace shops

Google Chat is the Workspace-native chat that finally became competent in 2025. Spaces, threaded replies, and Meet integration all live inside the Gmail Android app or a standalone Chat app, and Gemini can summarize a Space you missed while away.

Where it falls short: External-user support in Spaces is still awkward compared to Slack Connect. Third-party integrations are limited to Google’s own ecosystem plus a small partner list. Advanced permissions live in the Workspace admin console rather than inside Chat.

Pricing:

Migrating from Slack: Google’s Slack import tool moves channels and messages, though threading structure sometimes flattens.

Download: Google Play

Bottom line: Default pick for any organization already on Google Workspace.

How to choose

FAQ

What is the best free Slack alternative on Android?

Discord and Google Chat are both fully free for small teams. Element’s Home tier is free for personal use, and Rocket.Chat plus Mattermost are free forever when self-hosted.

Can I export my Slack workspace to another app?

Slack’s own workspace export produces a ZIP that Rocket.Chat, Mattermost, Zulip, Google Chat, and Teams can all import. Custom emoji, canvas documents, and third-party app data mostly do not transfer.

Is Element really encrypted end-to-end?

Yes. DMs and encrypted rooms use the Olm and Megolm implementations of the Signal Protocol variants. Element’s servers store ciphertext only.

What do teams use instead of Slack in 2026?

The mix runs Teams for Microsoft 365 shops, Google Chat for Workspace shops, Discord and Element for smaller teams, and Rocket.Chat or Mattermost for teams that must self-host.

Is Microsoft Teams cheaper than Slack?

Teams Essentials at $4.00/user/month undercuts Slack Pro at $8.75/user/month, and Microsoft 365 Business Basic at $6.00/user/month adds Office apps and Exchange on top.
