Slack is a messaging app for work. Conversations are organised into channels, and the app adds direct messages, voice and video huddles, file sharing and connections to other tools. The desktop app for Windows, macOS and Linux and the mobile apps for Android and iOS all connect to the same workspaces. The current Windows version on slack.com is 4.52.178 (October 2026).
Our file check
File check — 17 October 2026 UTC: We downloaded the official installer SlackSetup.exe (Windows x64 installer, 158.9 MB) from downloads.slack-edge.com (linked from slack.com) and did not run it.
SHA-256: edec34a6cd42a33da7556bac0ceb4046ae9e37ac0b1a4ae83a1b321c381ee062. The publisher does not publish a checksum, so this is the value we measured; use it only for this exact file. Windows reports a valid Authenticode signature from Slack Technologies, LLC.
A matching hash proves the file is byte-for-byte the publisher’s release. It is not a malware scan, and we did not install or test the program. Check your own copy with our SHA-256 checker.
Who it suits
Teams and communities that want organised group chat. You need to be invited to a workspace or create one before the app is useful.

Price and free plan limits
The app is free to install; what you can do depends on the workspace’s plan. Slack’s help centre lists these Free plan limits:
- Access to 90 days of message and file history.
- Messages and files older than one year are permanently deleted.
- Up to 10 integrations with other apps.
Paid plans remove those limits. The plan belongs to the workspace, so what you see depends on the workspace you join.
