1. Slack — Best Overall for Business Teams

Slack is the default. There’s a reason every startup, agency, and remote team gravitates toward it — the UX is that good. Channels, threads, huddles, and 2,600+ integrations make it the connective tissue of modern work.

Free: 90-day message history, 10 app integrations, 1:1 huddles (audio calls), unlimited channels and users.

Paid: Pro $7.25/user/mo (annual), Business+ $12.50/user/mo, Enterprise Grid (custom).

Why teams love it:

  • Threading keeps conversations organized. No more scrolling through 200 messages to find context.
  • Huddles — instant audio calls without scheduling a meeting. Click, talk, done.
  • 2,600+ integrations. Jira, GitHub, Salesforce, Google Drive, Notion — everything pipes notifications into Slack.
  • Slack Connect lets you chat with clients and partners in shared channels. No more email chains.

The catch: 90-day message history on Free is painful. Three months in, your early conversations vanish. Pro at $7.25/user solves this but adds up — a 20-person team pays $1,740/year. And Slack does one thing: messaging. No built-in video conferencing (huddles are audio-only for groups), no document editing, no project management.

Slack cost: 20-person team
$1,740/year (Pro, annual billing)
Free: $0 but you lose messages after 90 days
Pro: $7.25 × 20 × 12 = $1,740/year
Business+: $12.50 × 20 × 12 = $3,000/year
Most teams are fine on Pro. Business+ adds compliance features for regulated industries.

2. Microsoft Teams — Best for Microsoft Shops

If your company pays for Microsoft 365, you already have Teams. It’s included. That makes the “cost” of Teams effectively $0 for millions of businesses.

Free: Teams Essentials $4/user/mo standalone, or included free with any Microsoft 365 Business plan ($6+/user/mo).

Why teams love it:

  • Video meetings are best-in-class. Screen sharing, breakout rooms, meeting recordings, live captions, AI-powered meeting notes (with Copilot).
  • Deep integration with Word, Excel, PowerPoint, SharePoint, OneDrive. Edit documents without leaving the chat.
  • Channels + tabs organize work by project. Pin a shared Excel file, a Planner board, and a wiki in one channel.
  • If you already pay for Microsoft 365, Teams costs nothing extra.

The catch: The interface is cluttered. Chat, Teams, Channels, Activity — new users get lost. Moving between sections feels heavier than Slack. And Teams outside the Microsoft ecosystem is awkward — the integrations are good but not as seamless as Slack’s.

3. Discord — Best Free Option for Small Teams

Discord was built for gamers. But in 2026, startups, dev teams, and creator businesses use it as their primary communication tool. Why? Because it’s free and it works.

Free: Unlimited users, unlimited voice channels, unlimited message history, screen sharing, video calls up to 25 people, file uploads up to 25MB.

Paid: Nitro $9.99/month adds larger file uploads (500MB), HD video, custom emoji, and longer messages. Server boosts ($4.99/mo) unlock vanity URLs and higher audio quality.

Why teams love it:

  • Always-on voice channels. Drop into a voice channel like walking into a room. No scheduling, no meeting links. This is Discord’s killer feature for remote teams.
  • Free forever with no meaningful limitations on core features.
  • Fast and lightweight compared to Teams or Slack.
  • Bot ecosystem lets you automate moderation, notifications, and workflows.

The catch: No enterprise security (no SOC 2, no HIPAA, no SSO on most plans). No formal admin controls. No business integrations with tools like Salesforce or Jira. If compliance matters, Discord isn’t an option. But for a 5-person startup that just needs to talk? Hard to beat free.

4. Google Chat — Best for Google Workspace Users

Free: Included with any Google account (via Gmail). Full Chat and Spaces functionality included with Google Workspace ($7+/user/mo).

Why teams love it: It’s already there. If you use Gmail, Google Chat is one click away. Spaces (group chat rooms) integrate with Google Drive, Docs, and Meet. No new app to install, no new login to remember.

The catch: Google Chat is fine. Not great — fine. The interface is basic. Threading is less intuitive than Slack. The integration ecosystem is limited to Google’s own tools. It works as a “good enough” chat solution for teams already deep in Google Workspace, but nobody chooses Google Chat on its own merits.

5. Zoom Workplace — Best for Meeting-Heavy Teams

Free: 40-minute group meetings, 100 participants, basic chat.

Paid: Pro $13.33/user/mo, Business $18.33/user/mo.

Zoom added persistent chat (Zoom Team Chat) to compete with Slack and Teams. The chat is decent but not the reason you’d pick Zoom. You pick Zoom because your team spends 4 hours a day in video meetings and Zoom’s call quality is consistently the best.

The catch: Zoom’s chat feels bolted on. It works, but it doesn’t have the channel organization, threading, or integration depth of Slack. And $13.33/user is expensive when Slack Pro costs $7.25.

6. Pumble — Best Budget Slack Alternative

Free: Unlimited message history, unlimited users, 10GB storage, 1:1 video calls.

Paid: Pro $2.49/user/mo, Business $3.99/user/mo, Enterprise $6.99/user/mo.

Pumble is Slack at a third of the price. Channels, threads, direct messages, voice calls — the same structure, similar interface, fraction of the cost. Free plan includes unlimited message history, which Slack’s free plan dropped.

The catch: Smaller integration ecosystem. If you need 2,600 apps piping into your chat, only Slack delivers that. But if you need channels, threads, and unlimited history for $2.49/user? Pumble is surprisingly good.

7. Rocket.Chat — Best for Self-Hosted / Privacy

Free: Open source, self-hosted, unlimited everything.

Paid: Cloud-hosted from $4/user/mo.

Rocket.Chat is the only tool on this list you can run on your own servers. Full control over your data. No third-party access. Popular with government agencies, healthcare organizations, and privacy-focused companies.

The catch: Self-hosting requires technical expertise and server maintenance. The UI is functional but not polished. You’re trading convenience for control.

Cost Comparison: 20-Person Team

Tool (paid tier) Annual cost What’s included
Discord $0 Everything (no enterprise features)
Pumble Pro $598 Unlimited history + group video
Teams Essentials $960 Chat + 300-person meetings
Google Chat $1,680 Chat + full Workspace suite
Slack Pro $1,740 Unlimited history + integrations
Zoom Pro $3,199 Chat + unlimited meetings

Discord at $0 is unbeatable on price. Pumble at $598/year delivers Slack-like features at a third of the cost. Teams is the value play if you’re already on Microsoft 365 (effectively $0 extra). Slack at $1,740/year is the premium choice — you’re paying for the best UX and integration ecosystem.

Who Should Pick What

Our Verdict

Best overall: Slack Pro ($7.25/user). Best UX, best integrations, best threading. The standard for a reason.

Already on Microsoft 365: Microsoft Teams. It’s included — don’t pay for Slack unless Teams genuinely frustrates your team.

Startup on zero budget: Discord. Free, unlimited, fast. Accept the lack of enterprise features and move on to building your product.

Google Workspace shop: Google Chat. It’s right there in Gmail. Good enough for teams that don’t need advanced chat features.

Need cheap Slack: Pumble ($2.49/user). 70% of Slack’s features at 34% of the price.

Meeting-first team: Zoom Workplace if video call quality is your top priority. Use Slack or Teams for async chat alongside it.

Privacy/compliance requirements: Rocket.Chat (self-hosted). Full data control on your own servers.

Not sure? Start with Slack Free. If 90-day history and 10 integrations aren’t enough after a month, upgrade to Pro. If they are enough, you just saved $1,740/year.

Frequently Asked Questions

Is Slack worth paying for when Teams is free?

If you’re already on Microsoft 365, Teams is the logical choice — it’s included. If you’re not, or if your team finds Teams clunky, Slack Pro at $7.25/user is worth the cost for better UX and integrations. Try both free tiers for two weeks before deciding.

Can Discord replace Slack for business?

For teams under 20 people with no compliance requirements: yes. Discord’s always-on voice channels are actually better than Slack’s huddles. But you lose enterprise security, business integrations, and admin controls. Fine for startups. Not fine for regulated industries.

Do I need a separate video tool if I use Slack?

Probably. Slack huddles handle quick audio calls but lack full video conferencing features. Most Slack teams also use Zoom, Google Meet, or Teams for scheduled video meetings. Budget $13-18/user/month for Slack + Zoom if video meetings are frequent.

What happens to my Slack messages after 90 days on Free?

They’re hidden, not deleted. Upgrade to Pro and they reappear. Slack uses this as a conversion lever — your data is still there, you just can’t see it without paying.
