Slack Free Plan Limits: History, Apps & Pricing

Slack’s free plan gives you access to the most recent 90 days of messages and files, up to ten app installations, and 1:1 huddles. It can work for a new team, but the distinction between hidden history and deleted data matters as soon as chat becomes a record of your work.

This guide explains the current limits, what changes with Pro, and what the paid plan costs at common team sizes. It is for evaluating a first workspace as well as understanding an existing one.

Slack free-plan limits at a glance

Sources: free-plan feature limitations, retention settings, and current pricing. This is a summary of the differences discussed below, not the complete Slack feature matrix.

What happens after 90 days?

The 90-day limit is a rolling visibility window. As messages and files age out, they stop appearing in the free workspace’s accessible history. It is not a fixed total of messages that a team can send, so posting less often does not make a six-month-old conversation searchable. Slack explains the window in its usage-limits documentation.

For example, imagine an engineer records a database decision today. A teammate who joins four months later may be unable to read that discussion on Free, even if the channel has been quiet. That matters when chat is the only place your team records decisions.

Put durable decisions in a document or repository that the team owns, and use chat to discuss and link to that record. This is useful regardless of chat provider: a conversation is often easier to follow when its conclusion has a stable home.

Does Slack delete messages, or just hide them?

Both can happen at different times. The free retention options are one year or 90 days, and the setting can apply to files separately. Permanently deleted data cannot be recovered by paying later. Pins and saved items do not override retention. These details are covered in Slack’s retention guide.

If you need older history, check the workspace’s actual settings before relying on an upgrade. “Not visible on Free” and “still retained” are separate questions. Paid plans remove the free visibility window, but your configured deletion policy still matters.

Apps and file storage: what counts toward the limits?

Free permits ten third-party or custom app installations. Once that allowance is full, you must remove an app to add another or change plans. Review the installed-app list as a whole, including less visible operational tools. See Slack’s app-installation limit.

A small developer team might need GitHub, its issue tracker, Google Drive, a calendar, deployment updates, and error monitoring. Make that list before configuring the workspace. The number of teammates alone does not tell you how quickly the app allowance becomes a constraint.

For files, the current Free documentation focuses on the same 90-day access window as messages. Older articles describing a general “5 GB free workspace” allowance can give the wrong picture of the current offering. Check today’s file-visibility policy instead of planning around an old storage figure.

A practical setup is to store release artifacts, recordings, and shared documents in their source systems and link to them from chat. That gives you a place to manage the file independently, although the chat discussion around the link still follows the workspace’s history policy.

Can you have group calls or automations on Free?

Free huddles are 1:1. If three teammates need to join the same Slack huddle, evaluate a paid plan or use a separate meeting service. This distinction is easy to miss when a pricing page says that the free plan includes meetings.

Workflow Builder is also a paid feature. Connecting an app is not the same as having access to Slack’s workflow-building tools. If your process relies on a scheduled workflow, form, or multi-step automation, check its requirements individually. Both restrictions appear in Slack’s free-plan feature guide.

For many new teams, a separate video service is already part of the stack. In that case, group huddles may not justify a chat upgrade by themselves. A team that spends much of the day pairing in voice should give that feature more weight.

What does upgrading to Slack Pro cost?

Slack lists Pro at $7.25 per user per month with annual billing and $8.75 with monthly billing. The following estimates multiply those standard rates by the number of paid seats; they do not include taxes, discounts, credits, or other billing adjustments. Check the current pricing page before purchasing.

The useful comparison is the total cost of your collaboration setup. If Pro replaces another tool you would otherwise buy, account for that. If you already pay for meetings and file storage elsewhere, focus on the extra value you actually get from the chat upgrade.

When is Slack Free enough?

Free can be a reasonable starting point when conversations are mostly about current work, important decisions live elsewhere, your app list fits within the allowance, and you already have a place for group meetings.

Reconsider that choice if you regularly need old technical discussions, expect chat to act as your team’s institutional memory, or depend on several connected services. A two-person company can care deeply about history; a larger short-term project can be comfortable without it. Team size is only a rough proxy for those needs.

Before choosing, write down one example of a conversation you would want to find in six months, one automation you need, and one meeting you regularly hold. Check all three against the plan. That turns a long feature list into a concrete decision.

What if the free limits do not fit?

You can pay for Slack, combine Free with the other tools you already use, or choose another team-chat product from the start. Our Slack alternatives comparison covers twelve options with pricing, free-plan boundaries, hosting, and developer-notification setup. For a closer comparison of two familiar options, read Slack vs Discord for small teams.

Fryll is a currently free Slack alternative for developer teams and their agents. It combines channels, DMs, threads, desktop split view, and a conversation-token endpoint for posting from scripts. Its current experience is Mac-first, with the website handling accounts and onboarding. Voice/video calling and a full browser chat client are not currently included.

If that fits your team, explore Fryll for developers or try sending a notification. The current terms describe the free offering; they are not a permanent pricing guarantee.

Common questions about Slack Free

Is Slack’s free plan a trial?

No. Slack lists a continuing Free plan separately from its paid plans and promotional trials. A trial of paid features should not be confused with what the underlying Free plan includes. See Slack’s Free plan page.

Does upgrading bring back every old message?

No. An upgrade can make retained history accessible; it cannot recover data that retention settings or deletion have already removed. Check the actual retention policy before depending on older messages.

Is the free plan still limited to 10,000 messages?

The current published restriction is a rolling 90-day visibility window. Treat articles that use 10,000 messages as the current rule as outdated, and verify other figures in them against Slack’s present documentation.
