### 4.5/5
Expert administrator, professional services, 100-300 employees
> Slack — the backbone of any org's communication.
>
> Best-in-class and the clear market leader. Honestly, not much needs to be said: you can do everything with it, automate everything, connect everything. It's a genuine staple of the modern stack.
>
> The only real downsides: it can get a bit pricey, and the integrations that came out of the Salesforce acquisition haven't delivered the game-changing features or upside you might have hoped for.
>
> But none of that changes the verdict. Slack remains an absolute essential.
