Slack vs Discord 2026: What 25 People Pay for Chat

Discord is the lower bill for a 25-person community. The server is free, and Nitro at $9.99/mo belongs to the person who buys it. Slack Pro is $2,175 a year when all 25 people stay active. Pick Slack for a company workspace with a retention rule and an app directory. Pick Discord when adding people should not add seats.

Slack is workspace chat billed per active member. Discord is a server people join, with an optional personal subscription on top. Prices below were read on 30 October 2026. The wider field is in our best team chat apps ranking, and the Slack ladder alone is in Slack pricing.

Slack vs Discord at a glance

Question	Slack	Discord
What a 25-person group is buying	One workspace. The paid plan covers that workspace, not one account	One server. Membership is free. Nitro is a personal subscription
Entry paid rate	Pro, $7.25 per user a month billed yearly, or $8.75 billed monthly	Nitro, $9.99/mo on the Nitro page. $99.99 for a year in Discord's Nitro guide
Cheaper personal tier	No separate personal plan. A paid workspace still has a minimum of one billable member	Nitro Basic, $2.99/mo, or $29.99 for a year. No Server Boosts on Basic
Free start	Yes. 90 days of searchable history, 10 apps, huddles of two people	Yes. The server has no member fee
Message history	Free: searchable for 90 days, deleted after one year. Paid: kept for the life of the workspace by default	The caps page lists no channel history limit. Search stops at 5,000 results or 200 pages
Video	Paid huddles: 50 people, and 25 of them can turn video on	Voice with video: 25 people, at every boost level
Sign-in admin	Pro: Google sign-in. Business+: SAML, with 12 options named on the pricing page	The Nitro page and the caps article do not list SAML or SCIM
Open-community moderation	Posting controls in every channel start on Business+	AutoMod is available on every server

A Discord yearly rate can differ outside the US. Discord says so in its Nitro guide. The monthly figures on this page are the ones printed on the Nitro page.

What 25 people pay

The totals are our arithmetic on published rates: price, times the people who are billed, times 12. They are not quotes. Slack's count is active members, not names on a roster. Discord's count is people who choose to buy Nitro. A member who never buys Nitro adds nothing to a Discord bill.

Setup	People billed	12 months
Slack Pro, yearly, 25 active members	25	$2,175
Slack Pro, monthly, 25 active members	25	$2,625
Slack Business+, yearly, 25 active members	25	$4,500
Slack Business+, monthly, 25 active members	25	$5,400
Slack Pro, yearly, 5 full members and 20 single-channel guests	5	$435
Discord server, 25 members, no Nitro	0	Free
One Nitro subscription, paid monthly	1	$119.88
One Nitro subscription, paid yearly	1	$99.99
25 separate Nitro subscriptions, monthly	25, each optional	$2,997
25 separate Nitro subscriptions, yearly	25, each optional	$2,499.75
Slack Enterprise+	Sales	No published price

The two products do not bill the same object. Slack's pricing page prices Pro and Business+ per user per month. Its fair billing policy then counts only members who use Slack. Someone who has not used Slack in over 28 days is inactive, and Slack credits the unused time. Slack applies prorated credits to future payments; the credits are not cash refunds and expire when the paid subscription ends. If every member goes inactive, the workspace is still billed for one member until it drops to Free. Discord never runs that meter. Twenty-five people in a server cost the server nothing.

The last Discord rows are a warning, not a plan. Buying Nitro for all 25 people is more expensive than Slack Pro on the monthly path ($2,997 against $2,625) and still does not create a workspace admin tier. Nobody has to do that. One subscriber, or none, is a valid Discord setup. Slack cannot split a workspace that way: its help page says a paid plan applies to the workspace, and one account inside a free workspace cannot be upgraded on its own.

The three-month discount is easy to budget wrong. Slack's pricing page offers 50% off for three months on monthly Pro and Business+, at $4.38 and $9 per user a month, and only if the workspace buys online within seven days of being created. Annual plans are excluded, and so is Enterprise+. After three months the standard monthly rate returns. A team that misses the window, or that wants the yearly rate, should budget the undiscounted lines in the table.

Enterprise+ is the tier Slack's US pricing page sells as contact sales, with no list price. A company that needs several workspaces is in that conversation: Free, Pro, and Business+ each include one workspace, and unlimited workspaces are the Enterprise+ line.

Round 1: who is allowed in. Discord wins on headcount, Slack wins on a guest wall

An open group should not pay a seat to exist. Discord's caps article allows 25 million members on a server, at every boost level. An account can be in 100 servers, or 200 with Nitro. Joining is an invite. The person who arrives is not a line item.

Slack's paid-versus-free page says a workspace has no cap on people in a team or a channel. The bill is the cap. Owners, admins, full members, and multi-channel guests are paid when they are active. Bots are free. Single-channel guests are free, up to five for each paid active member, and only on a paid plan. Five paid Pro members can carry 20 single-channel guests, which is the $435 row, and each of those guests sees one channel. They are not a substitute for 25 people who need the same set of rooms. Multi-channel guests are billed as members. Guests disappear if the workspace falls back to Free, and the free-plan help says they would have to come back as full members.

That guest ratio is the closest Slack comes to a community price, and it fails the test a club actually has. A book group, a game night, or a customer community that talks in more than one channel will either pay for full members or live with a single shared room per outsider. Discord's role list, capped at 250 roles and 500 channels, is how that server hides a room, and the caps page does not attach a fee to either number.

There is a second access limit that looks small until a company tries to outgrow one office. Slack Connect on a paid plan reaches partners in up to 250 organizations, in direct messages, group chats, or channels. Free Slack Connect is one-to-one only. Discord's equivalent is another invite into the same server, which is simpler and has none of the org boundary. For a company that already compares Slack with a suite, the seat math against Microsoft is a different page: Slack vs Microsoft Teams.

Round 2: history. Paid Slack wins

A work group that has to find a decision from last quarter cannot live on a 90-day window.

Slack's pricing page gives Free 90 days of searchable messages and files, and says free workspaces delete data after one year. The retention help lets a free workspace choose 90 days or one year, and anything older than a year is deleted. Upgrading opens the previous 12 months of messages and files that are still stored. Paid plans keep data for the life of the workspace by default, and owners can set a custom deletion window. That is the feature a company buys when it leaves Free. Our Slack review covers the product around that limit, and free Slack alternatives is the page for groups that want the history without this plan.

Discord's caps article does not list a retention period for channel messages. It does list a search cap: 5,000 results, or 200 pages, and then search shows a broken magnifying glass. Threads archive after three days by default, on every boost level, which is a short memory for a work thread even when the parent channel is still there. Audit log entries stay 45 days. A community that scrolls is fine. A team that treats chat as the record of a project is not, because Discord never publishes the "kept for the life of the workspace" line Slack prints on paid plans.

Message length is a smaller version of the same split. The caps article allows 2,000 characters on a free or Nitro Basic account and 4,000 on Nitro. Again, the longer limit belongs to the subscriber, not to the room.

Round 3: video. Tie on cameras, Slack free loses

Twenty-five people is the interesting size, because it is exactly Discord's video-in-voice cap.

Discord's caps article limits a voice channel with video to 25 members, and the number does not rise at Boost Level 1, 2, or 3. Go Live, and screen share without video, allow 50 members. A 25-person group can all be in a video voice channel, and a 26th person cannot. Stage channels are the larger room: 50 video seats at the base level and at Level 1, 150 at Level 2, and 300 at Level 3, plus 30 more seats for each boost past 14. A stage is a broadcast layout, not a huddle where everyone is a peer.

Slack huddles on the free plan allow two people. On paid plans they allow 50 people, and only 25 can enable video at once. A paid Slack workspace and an unboosted Discord server therefore land on the same camera count. Slack can keep another 25 people in the room on audio. Discord cannot add a 26th camera by boosting. Groups that need a meeting above that cap are shopping for a meeting product, which is the comparison in video conferencing pricing and the Zoom pricing breakdown. Zoom's review is the single-product page beside those.

Picture quality is where a boost, or a Nitro subscription, changes Discord without changing the headcount. Unboosted Go Live is 720p at 60 fps. Level 1, which takes two Server Boosts, keeps Go Live at 720p and 60 fps and raises audio from 96 kbps to 128 kbps. Level 2, seven boosts, raises Go Live to 1080p at 60 fps and audio to 256 kbps. Level 3, 14 boosts, raises audio to 384 kbps. Nitro's own screen share, on the account caps table, can go to source quality at 30 or 60 fps, and that perk follows the subscriber into a call. It does not raise the cap for everyone else.

Round 4: moderation. Discord wins for an open server

A community that anyone can join needs filters that do not wait for a paid admin tier. Discord's AutoMod FAQ, updated 15 June 2026, says AutoMod is available on every server. Keyword rules and the spam filter can block a message before it posts, in channels, threads, and text chat inside voice. A custom keyword rule holds up to 1,000 terms, 60 characters each. The mention-spam rule caps unique mentions at 50 per message. A custom block message can be 150 characters. Commonly flagged word lists and the spam filter are English only. Custom keywords can be any language. People with Manage Server or Administrator edit the rules, on desktop, and those same permissions are always exempt from the filters.

Raid protection is the other half. Discord's raid guide says that when a join raid is detected, new joiners can be asked for a CAPTCHA for the next hour, and admins get an alert. @everyone and @here can be turned off for ordinary roles. None of that requires Nitro.

Slack's moderation is a permissions model, and the strong version waits for Business+. On Free and Pro, posting permissions and the control over who can mention everyone apply to the #general channel only. Business+ and Enterprise+ extend posting permissions to any channel. That is the right tool for an announcement channel inside a company, and it is a weak tool for a public server that has to block raids on day one. Slack's pricing page also does not describe an equivalent of AutoMod's keyword filter. A company that wants SAML, not raid filters, is the Business+ buyer: the pricing page lists SAML there, with 12 identity providers including Okta, Google, and Azure. Pro stops at Google sign-in. Enterprise+ adds multiple SAML configurations.

Round 5: apps and files. Slack wins when the work tools matter

Slack's pricing page offers a directory of over 2,600 apps, with a hard cap of 10 on Free and no cap stated on paid plans. Paid cards call the integrations unlimited. The practical meaning for this group: a 25-person company that lives in a handful of tools will hit 10 apps on Free and will not hit a published cap on Pro. The directory is the reason many teams accept the seat fee, and the shortlist of what to connect is in best Slack integrations.

Discord does not sell a matching directory size on the Nitro page or the caps article. Apps and bots are installed on a server. AutoMod will not flag messages from an app installed on the server. It will flag an app that a user installed on their own account, and the action lands on that user. There is no 10-app ceiling in the caps table, and there is also no Salesforce-or-Jira catalog printed next to the price. A community bot is a natural fit. A company stack that expects a managed app directory is the Slack case.

Files split the same way, with a conflict on one number. An unboosted server, and Boost Level 1, allow 10 MB uploads for members. Level 2 raises that to 50 MB for every member. Level 3 raises it to 100 MB for every member. Those are server perks. Separately, the Nitro page lists 50 MB uploads on Nitro Basic and 1 GB on Nitro. The caps article, updated 2 March 2026, lists the account file-sharing limit as 10 MB, 50 MB on Nitro Basic, and 500 MB on Nitro. Basic matches across both pages. Nitro does not. Other members do not inherit the subscriber's upload size either way. A team that needs every person to send a 50 MB file is shopping for seven boosts, which is Level 2, not for one Nitro subscription.

Level 1 is the only boost level a single Nitro subscription can fill. Nitro includes two Server Boosts. Level 1 requires two. Level 2 requires seven, and Level 3 requires 14. Nitro Basic includes none, and it does not get the 30% discount on extra boosts that full Nitro includes. Discord's boosting FAQ does not print a dollar price for an extra boost. It does say that from 14 September 2026, an eligible Nitro subscriber can buy a boost and get the next month free, up to 20 boosts, on desktop, after which the boost renews at the regular rate. Moving a boost to another server waits on a seven-day cooldown. If the server then falls below a level, level perks stay for a 72-hour grace period and then go invalid. A community whose Level 1 depends on one person's subscription loses that level when the subscription ends, on that clock.

Who should pick which

Group	Pick	Why
A club, class, or customer community that talks in several channels	Discord, no Nitro required	The server has no member fee. AutoMod is on every server. Slack's free guest ratio still locks each outsider to one channel
The same community, if one person wants higher personal uploads or two boosts	Discord, one Nitro	$99.99 for the year, or $119.88 over 12 monthly bills. The other members stay on the free account limits
25 coworkers who need last quarter's messages and more than 10 apps	Slack Pro, yearly	$2,175 if all 25 stay active. History is kept for the life of the workspace by default
The same company, if some people stop using Slack	Slack Pro, still	Slack credits the unused portion after more than 28 days of inactivity; credits apply to future payments
SAML, posting controls in every channel, or ongoing Slackbot	Slack Business+	Those items are on Business+, at the $4,500 yearly line for 25 active people. Discord's Nitro and caps pages do not list SAML
Several workspaces under one admin	Slack Enterprise+	No published price. Lower Slack plans include one workspace
A video call larger than 25 cameras	Neither, for the camera count	Paid Slack allows 50 people in a huddle and 25 on video. Discord voice-with-video stops at 25 even when boosted. Use a meeting tool
Already paying for Microsoft 365 and comparing chat inside that suite	Read the Teams comparison	This page does not price Teams. The seat against Office is a different bill

Strengths and weaknesses

Discord: the server is free at 25 people and at a much larger member count, AutoMod runs on every server, and one Nitro subscription can hold Boost Level 1 without charging anyone else. Against that, Nitro does not upgrade the other members, the boosting FAQ publishes no price for the extra boosts Level 2 needs, voice with video stops at 25, search stops at 5,000 results, threads archive in three days by default, and the Nitro page's 1 GB upload does not match the 500 MB line on the caps article.

Slack: paid history is kept for the life of the workspace unless an admin shortens it, the directory lists over 2,600 apps, paid huddles hold 50 people, and single-channel guests are free inside the five-per-member ratio. Against that, 25 active people on yearly Pro are a $2,175 line, Free deletes data after a year and limits huddles to two people, posting controls in ordinary channels wait for Business+, and a paid plan cannot be bought for one account inside a free workspace.

How we checked

Rates and plan limits were read on 30 October 2026 on Slack's pricing page, Slack's fair billing policy, Slack's plans and features, Slack's retention help, Slack's huddle help, and Slack's guest roles. Discord figures come from the Nitro page, the Nitro guide (yearly rates, page modified 11 May 2026), Nitro and Nitro Basic, the account and server caps (updated 2 March 2026), the Server Boosting FAQ (updated 14 September 2026), the AutoMod FAQ, and Discord's raid protection guide.

The 12-month totals multiply those rates by the people who are billed. We did not run either product. Our editorial policy explains how comparisons are produced. Re-check both pricing pages before you buy, because the three-month Slack discount is limited and Discord's yearly rate can differ by country.

The 45-tool count is a read of Toolradar's published team chat category on 30 October 2026: 29 freemium, 5 free, 10 paid, and 1 custom. The distribution comes from the published category statistics.

FAQ

Is Slack or Discord cheaper for 25 people?

Discord, if the group only needs a server. Membership is free. Slack Pro is $2,175 a year for 25 active members on yearly billing, or $2,625 if those 25 stay on monthly billing, using rates checked in October 2026. Buying Nitro for all 25 people is optional and costs more than Pro on the monthly path, at $2,997 over 12 months.

Does Discord Nitro cover everyone on the server?

No. Nitro at $9.99/mo, or $99.99 for a year, is one person's subscription. It includes two Server Boosts, which is enough for Boost Level 1, and a 30% discount on extra boosts. Nitro Basic at $2.99/mo includes neither. Other members keep the free account limits, including a 2,000-character message and a 10 MB upload on an unboosted server.

How long does each product keep messages?

Slack's free plan can be searched for 90 days, and Slack deletes free-plan data after one year. Paid Slack keeps messages for the life of the workspace by default, and admins can shorten that. Discord's caps page lists no channel history limit. Search there stops at 5,000 results or 200 pages, threads archive after three days by default, and audit log entries last 45 days.

Can 25 people be on video at once?

Yes, at the cap on both, with different rules. A Discord voice channel allows 25 people with video, and boosting does not raise that number. A paid Slack huddle allows 50 people, of whom 25 can use video. Slack's free plan allows two people in a huddle. A larger camera count needs a meeting tool.

What happens if some Slack members stop showing up?

Slack stops billing them after they have not used Slack for over 28 days, and credits the unused time. Credits are prorated for the unused portion of the billing period and apply to future Slack payments; they are not cash refunds. If everyone goes inactive, the workspace is still billed for one member until it moves back to Free. Discord does not bill absent members, because it does not bill members at all.

Does either free plan work as a company workspace?

Slack Free works as a trial: 10 apps, two-person huddles, 90 days of search, and deletion after a year. It is a poor record for 25 employees. Discord's free server can hold the 25 people, with AutoMod, and it still has no SAML line on the pages we used, a 25-person video cap, and a 10 MB upload until the server reaches Boost Level 2.

How many Server Boosts does a Discord level take, and what do they cost?

Level 1 takes 2 boosts, Level 2 takes 7, and Level 3 takes 14. One Nitro subscription supplies the two boosts for Level 1. The Server Boosting FAQ does not list a dollar price for boosts bought on top of that. Extra perks such as a server tag cost 3 boosts each, separate from the boosts holding the level, and a dropped level keeps its perks for 72 hours.
