Best Slack Alternatives in 2026

Microsoft Teams is the most natural of the top slack alternatives for any company already using Word, Excel, and Outlook. Channels, direct messages, and video meetings live in one place, and files open from OneDrive or SharePoint without extra logins. That closeness cuts app switching for office teams. The downside is weight. Teams carries calendars, apps, and meeting tools that a small chat group may never use. If your company already pays for Microsoft 365, Teams is close to free in practice. If not, compare the Essentials price against simpler chat apps before you commit.

Discord started for gamers, but it now hosts study groups, creator communities, and small teams that live on voice. Text channels, voice rooms, and video calls work from one free account, and message history does not expire after 90 days on the free tier. That alone beats many paid chat tools. Business teams should note the limits. Admin controls, compliance tools, and guest management are lighter than in Slack or Teams. For a community or a casual team that values voice and low cost, Discord is one of the best free slack alternatives available today.

Google Chat is the quiet pick among alternatives to slack for Workspace companies. Spaces group conversations by project, direct messages stay simple, and Google Meet handles video without a separate app. Search across Chat, Gmail, and Drive helps when a decision lives in an old thread. A personal Google account gives you Chat for free, but business use sits inside a Workspace plan starting at Business Starter. Teams that need hundreds of niche integrations may miss Slack, but teams already living in Gmail and Docs will find Chat familiar and fast.

Mattermost is built for organizations that want to own their chat data. The open source Team Edition runs on your own servers, and paid editions add compliance, advanced permissions, and enterprise support. Developers get boards, playbooks, and integrations with common DevOps tools. Self hosting is both the strength and the cost. You gain control, but you also own updates, backups, and uptime. For regulated teams and technical companies, that trade is worth it. For a five person team with no IT support, a hosted app will be simpler.

Rocket.Chat is one of the most flexible open source slack alternatives, with chat, video, and customer messaging in one platform. Teams can host it themselves, control data location, and extend it through an open app framework. The Starter tier helps small self hosted teams get going without a bill. As with Mattermost, the real cost is operational. Someone must run the server, apply updates, and watch security patches. If your team has that skill, Rocket.Chat offers a level of control that hosted tools cannot match. If not, start with a hosted trial before you self host.

Zulip takes a different approach to chat, and it works best for teams drowning in noisy channels. Every message sits inside a topic, so a busy channel stays readable for days, not minutes. That structure suits engineering teams, open source projects, and distributed groups working across time zones. Cloud Standard costs $6.67 per user per month on annual billing, while self hosting is free and open source. The free cloud tier caps searchable history at 10,000 messages, so large teams should plan for paid or self hosted use. Once a team learns topics, going back to flat channels feels messy.

Twist is built for teams that want fewer interruptions. Conversations are threads with clear subjects, so people can catch up on their own schedule instead of watching a channel scroll past. That calm design helps remote teams spread across time zones. The free plan keeps only one month of history, which limits its use as a long term archive. Paid Unlimited costs $6 per user per month and removes that cap. If your team values deep work over instant replies, Twist is one of the best alternatives to slack for async work.

Pumble wins on price and on history. The free plan covers unlimited users and unlimited message history, which removes the most common reason teams leave Slack. Channels, direct messages, threads, and video calls cover the daily basics without a steep learning curve. Paid Pro starts at $2.49 per user per month on annual billing and adds more storage and admin controls. The integration list is smaller than Slack, and project tasks need the sister app Plaky. For small teams that mainly need chat with a searchable past, Pumble is hard to beat on value.

Chanty suits small teams that want chat and simple task tracking in one place. Messages, voice notes, and a Kanban board sit together, so a decision in chat can become a task without opening another app. Setup takes minutes, which matters for teams without IT support. The free plan works for very small groups, while Business costs $3 per user per month on annual billing and adds unlimited history and more storage. Larger companies will want stronger admin controls, but for a team of ten or twenty, Chanty keeps work visible and affordable.
