Other communication tools

Chanty

Lightweight team chat with built-in task/kanban management, aimed at small teams that find Slack overkill.

Discord

Community and informal team voice/text chat organized into servers and channels; popular with gaming, creator and increasingly small-team communities.

Mattermost

Self-hosted, open-source team chat for organizations (often government/regulated/dev-focused) that need to control their own data and infrastructure.

Rocket.Chat

Self-hosted or on-prem team chat with strong compliance/data-sovereignty options, suited to government, defense and regulated industries.

Twist

Asynchronous, thread-based team communication designed as a deliberate low-noise alternative to real-time chat tools like Slack.
