# 7 Best Slack Alternatives in 2026

The honest list of Slack alternatives: the enterprise standard, community-native chat, open-source self-hosting and the Microsoft-native option - what each does better, and when to stay.

*Updated October 22, 2026 · independently researched · verify prices with the vendors.*

Slack set the shape of team chat - channels, threads, integrations - and still executes it best. Teams shop for alternatives for three reasons: price at headcount (per-user fees add up fast), an existing Microsoft or Google stack with a chat already inside it, or a hard requirement for data control and self-hosting. Each alternative below wins one of those cases.

**The short version.** Short version: if your company runs on Microsoft 365, Teams is the honest switch. If your community is gamers, creators or open source, Discord. If self-hosting is the requirement, Mattermost or Rocket.Chat. If Slack's polish and integration graph are doing their job, stay - chat is where switching costs bite hardest.

| Product | Best for | Starting price | Key difference |
| --- | --- | --- | --- |
| [Microsoft Teams](https://www.microsoft.com/en-us/microsoft-teams/group-chat-software) | Organisations on Microsoft 365 that want chat included rather than added per seat. | Included with Microsoft 365; free tier | Chat bundled with the Office stack |

| [Flock](https://flock.com) | Small teams that want chat with a few tools built in, not an app platform. | Free tier; paid from ~$6/user | Simplicity with built-in productivity tools |
| [Mattermost](https://mattermost.com) | Organisations that must own the data: regulated industries, defence, on-prem requirements. | Free open source; paid cloud tiers | Self-hosted, open source, compliance-grade |

## 1. Microsoft Teams

Chat, meetings and files inside Microsoft 365 - the default where the company already pays for Office.

**Best for:** Organisations on Microsoft 365 that want chat included rather than added per seat.

**Starting price:** Included with Microsoft 365; free tier

Teams leads this list for an unglamorous reason: arithmetic. If the organisation already pays for Microsoft 365, Teams is already paid for, already provisioned, and already wired to the calendar, files and identity. It is heavier and clunkier than Slack in daily use - nobody seriously disputes it - but 'included' beats 'better' at 500 seats. Switch for the bundle, not the chat.

## 2. Discord

Community-native chat: voice-first, always-on rooms, permission graphs built for open groups.

**Best for:** Creators, open-source projects and communities - and startups that like its always-on rooms.

**Starting price:** Free; optional Nitro

## 3. Google Chat

Chat inside Google Workspace - Gmail-native threads, spaces and Meet one click away.

**Best for:** Organisations on Google Workspace that want zero extra vendors.

**Starting price:** Included with Google Workspace

## 4. Zoho Cliq

Team chat inside the Zoho suite, with per-user pricing that undercuts the big two.

**Best for:** Teams standardising on Zoho's apps who want chat from the same vendor.

**Starting price:** Free tier; paid from ~$4/user

## 5. Flock

Lean team chat with built-in to-dos, polls and announcements - less platform, more messenger.

**Best for:** Small teams that want chat with a few tools built in, not an app platform.

**Starting price:** Free tier; paid from ~$6/user

## 6. Mattermost

Open-source team chat built for self-hosting and compliance-heavy environments.

**Best for:** Organisations that must own the data: regulated industries, defence, on-prem requirements.

**Starting price:** Free open source; paid cloud tiers

## 7. Rocket.Chat

Open-source chat with strong omnichannel - live chat widget and messengers into one inbox.

**Best for:** Support teams that want customer conversations and internal chat on one self-hosted platform.

**Starting price:** Free open source; paid tiers

## Microsoft Teams vs Slack

| | Microsoft Teams | Slack |
| --- | --- | --- |
| **Cost shape** | Bundled with Microsoft 365 | Per-user, adds up at scale |
| **Daily polish** | Heavier, busier interface | Cleaner, faster, better search |
| **Meetings** | Native, calendar-deep | Huddles plus every third-party call app |
| **Integrations** | The Microsoft graph | The largest third-party directory |
| **Best when** | You already pay for Office | Chat is the workspace, not an add-on |

## When to stay with Slack

Chat is the highest-friction switch in software: every integration, workflow and habit your team has lives in the current channel list. Slack's integration graph and search are still the best in class. Switch for a structural reason - cost per head, a mandate, self-hosting - and migrate cold turkey; half-migrations please nobody.

## FAQ

### What is the best free Slack alternative?

Discord, if your team tolerates its community-first shape - the free tier is genuinely unlimited. Teams' free tier and Zoho Cliq's free plan are the closest to a conventional office chat that costs nothing.

### Can Slack be self-hosted?

No. If the data must live on your servers, the realistic options are Mattermost and Rocket.Chat - both open source, both mature, neither with Slack's polish or integration directory.

### Is Teams really cheaper than Slack?

Only if you already need Microsoft 365. Then chat rides on a licence you would buy anyway, and Slack is a genuine add-on per head. Without the Office bundle the pricing is closer than it looks.

### Why is a launch board publishing software comparisons?

The board's products compete in software categories, so we research the categories. Where a board product genuinely competes we mark it as board-verified with its frozen offer; everywhere else the research is independent and says so. The disclosure is on every page.
