Slack: pricing, pros and cons
Slack made channel-based work chat the default, and its integration directory is still the deepest in the category. It is also the reason most teams discover that per-seat chat pricing scales faster than headcount does.

The honest assessment
Slack: pros and cons
Per-seat price climbs steeply once you need compliance exports and unlimited history.
What it does well
- 2,600+ integrations — almost anything you run already posts into it
- Huddles turn a thread into a call without a scheduling step
- Search and retention controls that hold up at enterprise scale
What it costs you
- The free plan hides messages older than 90 days, which quietly makes history unusable
- Business+ pricing roughly doubles the bill the moment you need SAML or data exports
- Guest and connect seats add up fast when you work with agencies or clients
Fit
Who Slack suits
Choose it if
- A 20–200 person company that already runs a lot of SaaS and wants everything posting into one place
- Teams working daily with external agencies or clients, where Connect earns its keep
Look elsewhere if
- Teams on a tight budget — the free tier hides history and the compliance tier roughly doubles the bill
- Distributed teams across many time zones, where channels produce more catch-up than they resolve

Questions
Slack, answered
What is Slack best for?
A 20–200 person company that already runs a lot of SaaS and wants everything posting into one place. Teams working daily with external agencies or clients, where Connect earns its keep. In short: the default team chat tool, with the deepest app directory of any.
What are the downsides of Slack?
The free plan hides messages older than 90 days, which quietly makes history unusable. Business+ pricing roughly doubles the bill the moment you need SAML or data exports. Guest and connect seats add up fast when you work with agencies or clients. The trade-off in one line: Per-seat price climbs steeply once you need compliance exports and unlimited history.
How much does Slack cost?
About $8.75/seat/mo on its common paid tier — roughly $5,250 a year for 50 people. There is a free tier. That figure is our unverified estimate; confirm it with the vendor before budgeting.
What are the best Slack alternatives?
In team communication the credible alternatives are Discord, Mattermost, Microsoft Teams, Zulip. Which fits depends on your team size, budget and non-negotiables — our questionnaire ranks all of them against your answers in about three minutes.
Is Slack worth switching away from?
Only if one of its real drawbacks is costing you something concrete. Per-seat price climbs steeply once you need compliance exports and unlimited history. If none of the downsides above describe your situation, staying is almost always cheaper than moving — a migration costs weeks, and a tool that merely annoys you is not worth them.
Prices are unverified estimates — useful for comparing orders of magnitude, not for budgeting. Confirm the current figure with the vendor before you commit to anything.
Is Slack still the right call for your team?
Answer about a dozen questions and we will rank Slack against every alternative in team communication — with the reasoning shown, and the cost of switching at your actual seat count.
