Slack

Slack is a collaboration hub for teamwork, where the right people are always kept in the loop and key information is always at their fingertips. Work in Slack happens in channels, so all the right people can be included, all relevant information kept in one place, and new team members are able to get up to speed easily. With Slack, teams are better connected.

Free Tier:

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.
