Team chat is supposed to cut down on email and meetings, but the wrong tool just moves the noise. Important decisions get buried in busy channels, people miss mentions, and a quick question turns into a call nobody needed. The right app keeps conversations organized by topic, makes old decisions easy to find and connects to the tools your team already works in.
This guide ranks four apps by how well they handle day-to-day work communication. Slack is the strongest all-round chat tool. Microsoft Teams wins when your company already lives in Word, Excel and SharePoint. Discord is a free, voice-first option for communities and informal groups. Zoom Workplace leads with video meetings and adds chat around them. Let your existing tools guide the decision.

Best overall
Slack
Channel-based team chat with huddles and workflows
0Organized channels, quick huddles and a deep integration directory make it the best home for team chat.
Slack is still the best place for a team to talk, because it keeps conversations easy to follow. Channels split work by project, team or topic, threads keep side discussions out of the main flow, and search makes old decisions findable. Huddles start a quick voice call without a meeting link, which replaces a lot of short meetings. Slack Connect even lets you share channels with clients and partners.
Its biggest advantage is integrations. Alerts from GitHub, support tickets, calendar reminders and sales updates can all land in the right channel, and Workflow Builder automates routine requests like daily check-ins or time-off forms. The catch is cost. The free plan only shows your last ninety days of messages, and per-seat pricing gets expensive as a team grows, so budget for it before you commit.

Best for Office users
Microsoft Teams
Chat, meetings and files built into Microsoft 365
0Chat, meetings, calls and shared files in one place, built to work closely with Word, Excel and SharePoint.
Microsoft Teams is the practical choice when your company already runs on Word, Excel, Outlook and SharePoint. Chat, meetings, calling and shared files live together, and documents open right inside a conversation so people can edit them together. Because Teams comes with many business plans for those apps, you may already be paying for it. Admins get strong security and compliance controls, which matters in regulated industries.
On eligible plans, Copilot can recap meetings, which helps in meeting-heavy weeks, and a free personal version covers family calls. The catch is the experience. Teams feels heavier and more cluttered than Slack, the learning curve is steep, and it's an awkward fit if your team works in Google Workspace. Choose it because it fits the tools your company already pays for, not for how pleasant it is to use.

Best free for groups
Discord
Voice, video and text hangouts for communities and friends
0Free drop-in voice rooms, text channels and screen sharing suit communities, clubs and informal project groups.
Discord is the best free option for groups that aren't a traditional company: open source projects, hobby clubs, student teams and volunteer groups. Servers mix text channels with drop-in voice rooms, so people can hop in to talk without scheduling anything, and screen sharing makes it easy to work through a problem together. Roles, permissions and bots keep a growing server organized as more people join.
Nearly everything important is free, including voice, video and screen sharing, which is rare for a tool this capable. The catch is that Discord isn't built for formal work. Busy servers get noisy and hard to follow, it lacks the admin and compliance tools companies expect, and text messages are not end-to-end encrypted, so Discord can access them for moderation. Use it for communities and casual collaboration, not client work.

Best for meetings
Zoom Workplace
Video meetings plus chat, docs and whiteboards in one app
0Dependable video meetings that guests can join easily, with team chat, docs and whiteboards built around them.
Zoom Workplace earns a spot because many teams talk more on video than in text. Meetings connect quickly, hold up on weak connections and are easy for guests to join from any device, which matters when you meet clients, students or contractors outside your company. Around the meetings, Zoom has added team chat, docs and whiteboards, so a meeting's follow-up can live in the same app.
On paid plans, AI Companion summarizes meetings, so people who missed a call can catch up without watching a recording. The catch is that chat and docs feel secondary to meetings and trail Slack and Teams. The free plan also ends group meetings after forty minutes. If your team mostly works in meetings and needs chat on the side, Zoom fits. If chat is the center of your day, choose Slack.

What should you look for in a team chat app?
Look first at how conversations are organized. Channels by project or topic, threads for side discussions and good search stop important decisions from disappearing. Then check integrations: the best chat apps pull in alerts from the tools your team already uses, so people stop switching windows all day. Quick voice or video calls inside the app also cut down on scheduled meetings.
Next, look at the free plan's limits and the per-seat price as you grow. History limits matter more than they seem, because old decisions live in chat. Check admin controls, guest access for clients and how well the app fits the office apps your company already uses. A chat tool that fits your existing tools will get used, and one that fights them won't.
Should your team use Slack or Microsoft Teams?
Choose Slack if your team values a fast, well-organized chat experience and uses many third-party tools, especially developer and business apps. Choose Microsoft Teams if your company already pays for Word, Excel, Outlook and SharePoint, since Teams is often included and plugs straight into them. Either way, you can still talk with outside partners through Slack Connect or Teams guest access.

Frequently asked questions
What is the best free team chat app?
Discord is the most generous free option, with voice, video and screen sharing included, but it suits communities better than companies. Slack's free plan is better for work, though it only shows your last ninety days of messages.
Is Slack better than Microsoft Teams?
Slack is nicer to use and has stronger third-party integrations. Microsoft Teams is the better value if your company already pays for Word, Excel and Outlook business plans, since it is often included.
Can you use Discord for work?
You can, and plenty of open source projects and small teams do. But text messages are not end-to-end encrypted and it lacks the admin and compliance tools most companies need, so Slack or Teams is safer for client work.
Is Zoom a team chat app?
Partly. Zoom Workplace includes team chat, docs and whiteboards, but its strength is video meetings. Use it alone if your team mostly talks on calls, or pair it with Slack if chat is central.
