Review Slack?

Reviewers mostly see Slack as a strong daily hub for team communication: channels and threads keep discussions organized, search is often praised, and integrations with tools like Google Drive, GitHub, Jira, Zoom, and Trello make workflows smoother. Several users say it beats email and feels cleaner or more flexible than Teams, Discord, or WhatsApp for work. The main complaint is noise: too many channels, notifications, and buried threads can make it feel cluttered. Some also mention learning curve, free-plan limits, pricing, and occasional performance or video issues.

What's great

user-friendly interface (30)remote team collaboration (94)

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.

I’ve been using Slack for a few months, and it has become the hub for our remote team. The channel organization and threaded conversations keep discussions tidy. Thousands of integrations let us pull in the tools we already use. The UI is clean and search works fast.

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 (25)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.
