Full Review

Slack remains the de facto standard for synchronous team chat in 2025 thanks to its polished UX and huge integration library Connecteam Review.

New 'huddles' with video and screen-share blur the line between chat and stand-ups.

The generous free tier lets startups onboard unlimited teammates, but only 90 days of searchable history means serious archives require a paid upgrade Tech.co.

Workflow Builder automations partly offset message overload by routing routine updates to threads.

As workspaces grow, premium per-seat pricing and constant pings can erode its appeal, yet Slack's ecosystem and reliability keep it ahead of most rivals for now Tech.co.
