Review Slack?

Reviewers mostly see Slack as the default hub for day-to-day team communication: channels, threads, search, huddles, file sharing, and broad integrations help teams replace internal email, stay aligned, and move faster, especially in remote or startup settings. Users repeatedly praise its speed, organization, and ability to pull tools like GitHub, Jira, Drive, and Zoom into one place. The main complaints are just as consistent: notification overload, channel sprawl, confusing or easy-to-miss threads, feature clutter, free-plan limits, and occasional performance or video issues.

What's great

user-friendly interface (32)search functionality (27)integration with productivity tools (85)real-time messaging (58)channel organization (56)threaded conversations (19)

Threads, channels, and search all in one place. Replaced 90% of internal email overnight. Integrations with everything we use means status, deploys, and tickets land where the team already is.

What needs improvement

notification fatigue (27)channel bloat (13)

Notification overload by default — sensible defaults for new users would help. Channels also multiply faster than anyone archives them; some auto-archive nudge for inactive ones would clean things up.

vs Alternatives

Discord

Teams (came free with our Microsoft stack) and Discord. Teams felt clunky and slow; Discord was fine but not built for work. Slack just felt like the tool the team would actually open every day.

What's great

user-friendly interface (32)remote team collaboration (96)

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.

What's great

workflow automation (12)file sharing (21)channel organization (56)remote team collaboration (96)

Slack remains one of the golden standards for remote team collaboration; my favorite part of the tool is the integrations it carries natively. Channels also help a lot for teams that wear many hats.

What needs improvement

mobile app performance (10)free version limitations (7)notification fatigue (27)video call quality (2)

Free version limits remain a blocker. However, many competitor tools have also lowered their free version limits so not the biggest flaw. I do think the mobile version can be further improved though!

I still use the other products but vary a lot of the situation. Lark is more of a super app that also includes gmeet/zoom and notion - used a lot more in Chinese companies. Teams is still heavily used in consulting / f500 companies. Discord is used more for gaming / community management for crypto and ai startups. Webex and Mattermost are more niches now.
