The Verdict
8x8 is built for international businesses and contact centers, with a focus on unlimited-calling and video-conferencing. Slack targets teams and enterprise and leads with channels and huddles.
On pricing, Slack is the clear winner for budget-conscious users — starting at $7.25/mo compared to $28/mo for 8x8. That $20.75/mo difference adds up quickly for growing teams.
Slack has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. 8x8 requires a paid subscription from day one.
Slack edges out on user ratings (4.4 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Bottom line: Slack has a slight overall edge — but if unlimited international calling matters most to you, 8x8 may still be the right call.
