Aircall vs Slack FAQ

Which one is cheaper?
Slack is the cheaper option, starting at $8/mo vs $30/mo for Aircall.
Can I use either one for free?
Slack has a free plan. Aircall doesn't — you'll need to pay from day one.
How do they charge?
Both use a per-seat model, so the comparison is straightforward — it comes down to features and limits at each price point.
Which one is a better deal?
Depends on what you need. Aircall: At $30-50/seat, Aircall sits mid-to-premium in the cloud calling space — pricier than bare VoIP tools like Grasshopper but cheaper than full contact-center suites like Five9 or NICE CXone. They're chasing SMB and mid-market sales/support teams who want call center features without enterprise-grade complexity or cost. Slack: Slack sits mid-to-premium in team chat — pricier per seat than Google Chat (bundled free with Workspace) and roughly on par with or above Microsoft Teams, which most companies already get for free inside Microsoft 365. They're not competing on price; they're betting the UX and integration ecosystem justify the premium over 'free' alternatives already sitting in a company's tech stack.
