Slack defined modern team chat, but in 2026 plenty of teams are looking elsewhere — the per-seat price adds up, the constant pings wreck focus, or they want everything in one suite instead of yet another subscription. The good news: there's a strong field of alternatives, from all-in-one platforms to open-source tools you can self-host. Here are eight worth knowing, each better than Slack at something specific.

Microsoft Teams
- Pricing
- 8.5/10
- Functionality
- 9.0/10
- Ease of use
- 7.8/10
- Support
- 8.6/10
What I like
Chat, calls and full Office integration, often already in your plan.
Best for
Organisations already paying for Microsoft 365.
Teams bundles chat, video, and deep Office integration, and if you're on Microsoft 365 it's effectively free. It's heavier than Slack but unbeatable on value for orgs already in the ecosystem.
Discord

- Functionality
- 8.4/10

- 8.6/10
- Support

What I like
Fast, free, with superb voice channels and a vibrant community feel.
Best for
Startups, communities and teams wanting free real-time chat and voice.
Discord started in gaming but many teams and communities now run on it. It's free, fast, and its always-on voice channels are genuinely better than Slack's. Less corporate, more lively — and the price is hard to argue with.

What I like
Async-first, thread-based design that kills the always-on pressure.
Best for
Remote and distributed teams who want calm, async communication.
Twist, from the makers of Todoist, is built around organised threads and async communication rather than real-time pings. For distributed teams drowning in Slack notifications, its calmer, more deliberate model is a relief.
Zulip
- Pricing
- 9.8/10
- Functionality

- Ease of use
- 7.8/10
- Support
- 8.0/10
What I like
Topic-based threading that keeps conversations organised and searchable.
Best for
Teams that hate losing context in busy channels.
Zulip's distinctive topic-based threading model keeps even busy channels organised, so you can follow exactly the conversations you care about. Open-source and self-hostable, it's a favourite of teams that value structure over chaos.
Chanty
- Pricing
- 9.0/10
- Functionality
- 7.8/10
- Ease of use
- 8.8/10
- Support
- 8.2/10
What I like
Simple, affordable team chat with built-in task management.
Best for
Small teams wanting easy, low-cost chat plus light task tracking.
Chanty is a clean, affordable Slack alternative aimed at small teams, pairing simple chat with built-in tasks and a tidy interface. For teams that found Slack overwhelming or pricey, it's an approachable, budget-friendly option.
The best Slack alternative depends on your specific gripe. Already on Microsoft or Google? The bundled option is nearly free. Want privacy and control? Go open-source and self-host. Want async-first calm instead of real-time noise? Pick a tool built for that. Name the Slack problem that's bugging you, then choose the tool designed to remove it.
