Review Slack?

Reviewers largely see Slack as the default hub for fast, organized team communication, especially for remote and startup teams. They repeatedly praise channels, threads, strong search, file sharing, huddles, and broad integrations that keep work moving without long email chains. Several users also say it feels cleaner or more flexible than Teams, Discord, or simpler chat tools. The main complaint is noise: too many notifications, crowded channels, buried threads, and growing feature clutter. Some also mention limits on free use, higher costs, and occasional performance or video issues.

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.
