Discord vs Slack: Which Is Better for Your Team or Community?

Discord vs Slack: prices and limits as of October 2026, message history, voice, integrations, security, and which suits a team or a community.

Choose Slack for a company or a team that works with clients: it's built for work, connects to the business tools you already use, and its paid plans add the admin, security and compliance features that companies need. Choose Discord for a community, a hobby group, a game, or a small informal team that wants free voice chat and unlimited message history without paying per person. As of October 2026 Discord is free to run, while Slack's free plan hides messages older than 90 days and paid plans start at $7.25 per user per month billed annually.

Discord vs Slack at a glance

Prices and limits as of October 2026, from Slack pricing, Discord Nitro, Discord's Nitro help page, account and server caps and file attachments FAQ.

How we compared

We compared the plans, prices and limits each company publishes on its own site as of October 2026, plus how each product is designed to be used. We did not run a survey or measure performance. Discord prices vary by country, so we quote US prices. Slack shows a 50%-off-for-3-months promotion on Pro and Business+ at the time of writing; we quote the regular prices. If we couldn't confirm a limit on the vendor's site, we left it out.

The real difference: who pays and who's in charge

The pricing models tell you who each product is for.

Slack charges the organisation per user. A company buys seats, an admin controls who's in the workspace, and the plan decides how long messages are kept and what security features you get. That's what a business wants: control, records and one bill.

Discord charges individuals for perks. Running a server costs nothing. Members can pay for Nitro to get things like bigger uploads and custom emoji anywhere, and anyone can "boost" a server to unlock perks for everyone in it. That's what a community wants: free to join, no per-member cost to the owner, and fans who can chip in.

Neither is wrong. Picking the tool that matches your situation avoids most problems later.

Slack in detail

Slack plans as of October 2026

Source: Slack pricing. Slack's comparison lists AI features by plan: thread and channel summaries from Pro, AI search from Business+, and enterprise search on Enterprise+.

What Slack does well

• Threads and channels for work. Conversations stay organised by project, client or team.
• Integrations. Paid plans have unlimited app integrations, and Workflow Builder (paid plans) automates routine steps such as request forms and approvals.
• Slack Connect. Shared channels with clients and partners, which is why agencies and B2B companies often end up on Slack anyway.
• Canvases and lists. Lightweight documents and trackers inside channels, on paid plans.
• Admin and compliance. Higher plans add SSO, user provisioning, retention rules, exports and audit logs.

Where Slack falls short

• The free plan's 90-day window. Older messages and files are hidden until you upgrade, which surprises teams that rely on search.
• Cost for big groups. Per-user pricing makes Slack expensive for a large, casual community.
• Voice is secondary. Huddles are good for quick calls, but there's no always-on voice room the way Discord has.

What's free and what costs money

Creating a server, channels, roles, voice channels and events is free. As of October 2026 the paid options are:

• Nitro Basic: $2.99/month in the US. Custom emoji and stickers anywhere, 50 MB uploads, custom app icons.
• Nitro: $9.99/month in the US. Everything in Basic plus 1 GB uploads, HD streaming, profile customisation, longer messages (up to 4,000 characters), joining up to 200 servers, and 2 Server Boosts.
• Server Boosts: level up a server for everyone in it. Discord's caps page lists perks by level, such as larger uploads for all members (50 MB at level 2, 100 MB at level 3), better audio quality and more emoji slots.

Discord says prices vary by country. See Discord Nitro.

Discord limits worth knowing

From Discord's caps page and file attachments FAQ, as of October 2026:

• Members per server: up to 25 million.
• Channels: up to 500 per server, including categories.
• Roles: up to 250.
• Voice channel with video: up to 25 people.
• Stage channels: up to 10,000 listeners without video; video stage seats from 50 up to 300 depending on boost level.
• Free uploads: 20 MB per file (Discord notes it is experimenting with limits).
• Audit log: entries kept for 45 days.

What Discord does well

• Free with full history. No per-member fees and no 90-day window.
• Always-on voice. Members drop into a voice channel the way people walk into a room. Great for study groups, co-working and gaming.
• Community tools. Roles and permissions, events, Stage channels for talks and AMAs, and bots for moderation and welcome flows.
• Scale. Servers can grow very large at no cost to the owner.

Where Discord falls short for work

• Business controls. We couldn't find SSO, user provisioning, data exports or retention policies offered as plan features, the way Slack lists them.
• Work integrations. Discord has bots and an App Directory, but the business-tool ecosystem (CRMs, help desks, project tools) is built around Slack.
• Perception. Some clients and employers will find a Discord invite informal.

Which should you pick?

When you need your own community space

Discord and Slack are both chat apps, and chat is a stream: good for talking, poor for things people need to find later, such as answered questions, member directories, course material or paid content. Communities often outgrow chat in a few predictable ways:

• Answers get buried. A searchable forum or knowledge base works better than scrolling. See how to build a forum.
• Paid membership. Gating content and handling subscriptions is easier on your own site. See how to build a membership site.
• Your brand and your data. On your own platform, the member list and content belong to you.

An AI app builder like Mythex can build that layer: you describe a member directory, a Q&A board or a members-only area in chat, watch it in a live preview, and publish it to a URL in one click, with a database, sign-in and file storage when the app needs them. Mythex Free gives 5 credits a day and Pro starts at $25 a month. Most communities keep Discord or Slack for the live conversation and use their own site for everything that should last. Our guide to building a community platform covers which parts are worth building yourself.

For real-time chat itself, don't rebuild it. Discord and Slack are very good at it.

Verdict

Slack is the better tool for work: it costs money per user, and you get control, integrations and compliance in return. Discord is the better tool for communities: it's free to run, has full history and excellent voice, and scales to very large groups. If you're a small team choosing between them only on price, remember Slack's free plan hides anything older than 90 days, and Discord doesn't offer the admin controls a growing company eventually needs.
