Review Slack?

Reviewers largely see Slack as the default hub for team communication: fast, reliable, and especially strong for channels, threads, search, file sharing, huddles, and broad integrations that keep work moving without email. Users say it works particularly well for remote teams, startups, and developer workflows. The main complaint is noise: too many notifications, crowded channels, buried threads, and feature clutter can make it feel overwhelming, especially across multiple workspaces. Some also mention limits or cost on lower-tier plans, plus occasional UX, mobile, video, or performance frustrations.

What's great

user-friendly interface (31)remote team collaboration (95)

Slack has been a solid tool for keeping team communication in one place. I really like how easy it is to follow conversations through channels, especially for day-to-day coordination. Best tools for teams especially startups.

What needs improvement

free version limitations (7)

Over time, channels and notifications can get out of hand if you’re not careful. The free plan also starts to feel limiting as the team grows, which is a bit disappointing.

vs Alternatives

Microsoft Teams

I also tried Microsoft Teams and a couple of simpler chat tools. Slack felt more flexible and quicker to adapt to for everyday use.
