Message, file, and app limits on the free version of Slack
Message, file, and app limits on the free version of Slack
You can use the free version of Slack for as long as you'd like, and there's no limit to the number of members who can be invited, but there are a few usage limits to consider:
Message visibility Only the most recent 10,000 messages can be viewed and searched.
File storage Add up to 5GB of files to your workspace.
Members can send unlimited messages in Slack, but only the most recent 10,000 can be searched and viewed in your workspace. Keep in mind that you'll only be able to see messages in public channels, private channels you belong to, and your direct messages when searching.
If your workspace exceeds the message visibility limit, members can continue to send messages, but older messages will be archived. If you upgrade your workspace to a paid plan, all archived messages will become available again.
What counts as a message
In general, anything typed into the message field and sent to a channel or direct message counts as a message. Here are some details to keep in mind:
A one-word message or single emoji are counted the same as a message with 500 words and multiple paragraphs.
Links, snippets, posts, uploaded files, replies in a thread, messages in archived channels, and messages from bot users all count towards your workspace's total number of messages sent.
On the free version of Slack, workspaces have up to 5GB of file storage available. Anything uploaded to a channel or a direct message (e.g., PDFs, documents, images, screenshots, audio and video files) counts towardsthis limit.
If your workspace reaches the limit, members can continue to upload files, but Slack will start archiving the oldest files to make room for new ones. Members won't be able to view archived files in channels, direct messages, or search results.
Like messages, archived files will immediately become available again if you upgrade to a paid plan. If you choose to upgrade, file storage limits will be determined by the total number of members (including Multi-Channel Guests) in your workspace:
10GB per member on the Pro plan
20GB per member on the Business+ plan
Note: Audio and video clips, deleted files and files added to Slack via apps (like Google Drive, Dropbox, etc.) do not count towards the file storage limit.
App installation limit
Members of workspaces on the free version of Slack can add up to 10 apps. Apps from the Slack App Directory and custom apps built for your team count towards this limit.
If your workspace reaches the app and integration limit, you can uninstall apps to make space for new ones, or upgrade to a paid plan to install as many apps as you'd like.
