Slack vs Microsoft Teams for Remote Workers: Which One Is Actually Worth Using?

If you’re a remote worker or freelancer, you’ve probably been asked to use both of these tools at some point. Maybe you picked one yourself, or maybe a client dropped you into their workspace without asking. Either way, you’re staring at two very different apps and wondering which one is actually worth your time.

Here’s the thing: Slack and Microsoft Teams are both good. Not equal, but both usable. One fits certain workers, workflows, and budgets better than the other. I’ve used both heavily across different projects and client setups, and I want to give you an honest breakdown so you can stop second-guessing yourself.

This isn’t a feature-by-feature checklist. It’s more like what I’d tell a friend who asked me over coffee which one to use.

Slack at a Glance

Slack launched in 2013 and basically redefined what workplace messaging could feel like. It’s built around channels, which are organized conversation threads for different topics, projects, or teams. Everything feels light, fast, and weirdly fun compared to most work software.

The free tier is usable but limited. You get 90 days of message history, one-on-one audio and video calls, and up to 10 app integrations. For solo freelancers just testing the waters, that can work for a while.

Paid plans start at $7.25/month per user for Slack Pro. That unlocks unlimited message history, group calls with screen sharing, and unlimited integrations. The Business+ plan runs $12.50/month per user and adds compliance exports, SAML-based single sign-on, and 24/7 support. Most small teams and freelancers will find the Pro tier more than enough.

Slack’s biggest strength is its community. There are thousands of Slack communities outside of work, from niche developer groups to freelancer networks, and having the app already open makes it easy to stay plugged into both.

Microsoft Teams at a Glance

Teams launched in 2017 as Microsoft’s answer to Slack, and it’s grown into something much bigger than just a chat app. It’s deeply embedded in the Microsoft 365 ecosystem, which means if your clients or employers use Word, Excel, SharePoint, or Outlook, Teams is going to feel like a natural extension of that setup.

The free version of Teams is pretty generous. You get unlimited chat, 60-minute group meetings, 5GB of cloud storage, and basic file sharing. It’s not crippled the way some free tiers are.

Paid plans start at $4/month per user for Teams Essentials, which bumps meetings to 30 hours and increases storage. The most popular upgrade for small businesses is Microsoft 365 Business Basic at $6/month per user. That includes Teams, Exchange email hosting, SharePoint, OneDrive, and web versions of the Office apps. For what you get, that’s a real deal.

Teams is also the default tool in many large companies and enterprise organizations. If you do contract work for corporate clients, there’s a decent chance they already use it.

Head-to-Head Comparison

Interface and Ease of Use

Slack wins here, pretty clearly. The interface is clean, intuitive, and doesn’t feel overwhelming when you first open it. Channels are easy to set up and browse. Notifications are manageable. You can get productive in Slack within the first hour.

Teams has improved a lot over the years, but it still feels heavier. More menus, more nested options, and it can take a few days to feel comfortable. The distinction between Teams (the group spaces), channels, and chats is also confusing for newcomers. That said, once you’re used to it, it works well.

If you’re onboarding clients or collaborators who aren’t particularly tech-savvy, Slack is a gentler introduction.

Messaging

Both tools handle messaging well. Slack has threading baked in and does it slightly better. Formatting options are good. Reactions, bookmarks, and reminders are all there.

Teams messaging has gotten better but still lags a bit in the feel of real-time conversation. It can sometimes feel more like email with a chat skin. That said, Teams does have a nice feature where you can message people outside your organization without adding them as full users, which comes in handy for client communication.

Video Calls

This one goes to Teams, and it’s not that close.

Teams video calls are excellent. The meeting interface is polished, screen sharing is reliable, breakout rooms work well, and the Together mode (where everyone appears in a shared virtual space) is actually useful for longer calls. Call quality is consistently strong.

Slack calls are fine for quick check-ins. But Slack’s video feature was never its core focus, and it shows when you’re running a 45-minute client meeting with multiple participants.

If video calls are a big part of your remote work setup, Teams has a real edge.

Integrations

Slack has one of the largest app directories you’ll find in any productivity tool. Thousands of integrations, including GitHub, Notion, Asana, Zapier, Google Calendar, HubSpot, and dozens more. If you need to connect your stack together, Slack can almost certainly do it.

Teams integrations work well, especially within the Microsoft ecosystem. SharePoint, OneDrive, Planner, and Loop all work natively. Outside of Microsoft products, the integration library is growing but still smaller than Slack’s.

For teams running non-Microsoft tools, Slack is probably more flexible. For teams already committed to Microsoft 365, Teams connects things in ways that actually save time.

Pricing

Here’s where things get pretty stark.

Slack:

Free: 90-day message history, 10 integrations, 1:1 calls
Pro: $7.25/month per user
Business+: $12.50/month per user

Microsoft Teams:

Free: Unlimited chat, 60-min meetings, 5GB storage
Essentials: $4/month per user
Microsoft 365 Business Basic: $6/month per user (includes Teams plus full Microsoft 365 suite)

Teams is cheaper at every paid tier, and the gap is real. When you factor in that the $6/month Microsoft 365 Business Basic plan includes email hosting, OneDrive, and Office apps, the value math gets pretty lopsided.

If budget is a real concern, Teams offers more for less.

Best Use Case

Slack is best for small creative teams, tech startups, and freelancers juggling multiple client workspaces. If you care about a fast, pleasant messaging experience, Slack is the right call.

Teams is best for corporate environments and anyone already deep in Microsoft 365. It’s also the better pick if you’re on heavy video calls or want an all-in-one setup without paying Slack prices.

Which One Should You Use?

You’re a solo freelancer. Go with Slack’s free tier to start. Most clients who invite you to collaborate will send a Slack invite anyway, and having the app installed costs you nothing. If you want to run your own workspace and don’t need message history beyond 90 days, the free plan is enough. If you need more, $7.25/month for Pro is reasonable.

You’re running a small remote team. This depends on what else you’re using. If your team lives in Google Workspace, Notion, and Asana, Slack will fit more naturally. If you’re already paying for Microsoft 365 or you want to cut costs, Teams at $6/month per user gives you a lot of bundled value. Honestly, either works fine at this scale.

A corporate client requires one of them. Use whatever they use. This isn’t a debate worth having. If a client puts you in their Teams workspace, get comfortable with Teams. If they’re on Slack, learn their Slack setup. Clients don’t care about your app preference. They care that you show up and communicate well.

You do a lot of video meetings. Teams, full stop. It handles meetings better than Slack does.

You’re managing multiple freelance clients at once. Slack handles this better. Switching between multiple workspaces quickly, each belonging to a different client, is something Slack does well. Teams can connect external organizations but the experience is clunkier.

Final Thoughts

Neither of these tools wins across the board. They’re built with different priorities, and they work better in different situations.

Slack is the better pure messaging experience. It’s faster to pick up, more fun to use, and has a wider integration library. It costs more per user on paid plans, but for small teams or solo workers, that’s usually manageable.

Teams is the better all-in-one platform, especially if Microsoft 365 is already in your life. The pricing is hard to argue with, and the video meeting quality is excellent. It’s also where most of the corporate world lives, which matters a lot if your clients are enterprise companies.

My honest take: install both. Use Slack for your own projects and client work where you have a choice. Learn Teams well enough to use it confidently when a client requires it. That combination covers almost every remote work scenario you’ll run into.

Both have free tiers worth trying. There’s no reason to commit to one before you’ve actually used them in your own workflow.
