Discord is free and it's generally more fun to use and better suited to informal messaging. Discord was meant for gaming, but it has evolved into a huge platform for all types of communities. Slack is far more work oriented than Discord, built for big or small team communication, it offers a wealth of workplace administration tools built in. Slack is more restrictive in its free plan, allowing it to send unlimited messages but only the last 10,000 can be searched and viewed 10 apps and integrations one-to-one video calls and two-factor authentication. Teams' free plan provides a fairly generous number of features like unlimited messages, meetings, and search support for up to 300 users 2GB of file storage per user and 5GB of shared storage one-to-one audio and video chat screen sharing two-factor authentication and data encryption. Slack is considered (as of 2022) the more mature platform and offers dozens of useful integrations, while Teams' strength comes from its full integration with Microsoft Office and that its cost is included in some Office 365 plans. Slack and Teams are competing communications platforms for workgroups, both offer voice and video chat, natively and via app integrations.

Slack also offers the option to use enterprise key management (EKM), single sign-on, and two-factor authentication to make data more secure. Slack encrypts data in transit and data at rest, but it doesn't offer end-to-end encryption. Slack is available on any device, so you can find and access your team and your work, on your desk or on the go. Slack brings team communication and collaboration into a single place, so you can get more work done.
