Official downloads

These URLs are the ones Slack Technologies Inc. declares in its own manifest. We do not proxy or shorten them, and we do not host a copy.

More than one architecture below. Check which one your Windows is if you are not sure.

Verify the file you downloaded

Run this against the file on disk. If the output does not match the hash below, the file is not what Slack Technologies Inc. published. Delete it.

Windows · PowerShell

Get-FileHash "SlackSetup.exe" -Algorithm SHA256

macOS · Linux

shasum -a 256 "SlackSetup.exe"

Expected output

Got a different hash, or one you cannot place? Paste it into the hash checker and it will tell you which program and version it belongs to, past releases included.

Install Slack silently

The unattended switch below is the one Slack Technologies Inc. declares in the installer manifest, not one we guessed by trying flags.

64-bit · user scope · publisher-declared

.\SlackSetup.exe --silent

Run it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.

Silent install commands for every program we index · silent uninstall

Download Slack for Mac

The macOS build as Homebrew declares it, with the same treatment as the Windows side: the publisher's own URL and a hash to check it against.

Is Slack safe to download?

Yes, in the sense we can actually verify: the installer downloads from slack-edge.com, which is a domain we have tied to Slack Technologies Inc.

Every one of the 3 installers on this page comes with the SHA-256 Slack Technologies Inc declared, so you do not have to take our word for it: hash the file you downloaded and compare.

What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.

If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.

How the 100/100 score is calculated · why the source matters more than the reputation

Install Slack with winget

Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.

Install

winget install --id SlackTechnologies.Slack --exact

Upgrade later

winget upgrade --id SlackTechnologies.Slack

Why --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.

Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.

Old versions of Slack20 with hashes

The version history of Slack, each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.

We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

Publishers take old builds offline without warning, so a link here can stop working even though the hash stays correct forever. If you already have the file, the hash is what matters: it tells you whether what you have is what they published.
