Trying out Slack?

Free’s got everything you need.

Create a workspace

Get the basics, and get more done.

Unlimited private & public channels

Create a channel for every project, topic, or group. Private or public, they’ll have a place on Slack.

10,000 searchable messages

Every message in Slack is indexed and searchable, so nothing gets lost or forgotten. On our free plan you can access the most recent 10,000.

Up to 10 apps

Connect with the apps and services you use everyday — and get information in front of the people who need it faster.

1:1 voice & video calls

Go from typing to talking in a single click, with 1:1 voice and video calls, directly inside Slack.

File sharing

All the public files your team shares are kept in one place — so new people coming into the team can get all the context they need, and nothing is tucked away in a forgotten folder.

Personalized notifications

With the ability to fine-tune notifications to your needs, you’ll never miss a beat on the conversations that matter to you.

Our commitment to security and your data.

We use Slack for nearly all of our communication. Ensuring that the Slack service remains secure is vital to protecting our own data. That means the security of your information is required for our success as a business.

Even before Slack, we’ve been putting services on the internet for a long time. We’ve coded, tested and administered services running on thousands of physical servers in data centers around the world and bring the collective wisdom that comes with many decades of secure practice.
