Discord vs Slack

Discord is a communication platform, founded in 2015 in San Francisco by Jason Citron and Stan Vishnevskiy, organized around servers: shared spaces with text channels, voice channels, video calls, forums, stages for live audio events and threads. It began as a voice chat app for gamers and has grown into the home of developer communities, open-source projects, creator fan bases and the user communities of many startups.

Server owners configure roles and permissions per channel, use AutoMod and bots for moderation, and connect integrations through webhooks and the developer platform, which also supports apps and activities inside Discord. Voice and video run with low latency, screen sharing works for streaming and support, and forums keep questions organized. Discord is free for nearly unlimited use; Nitro subscriptions add larger uploads, HD streaming and cosmetic perks, while server boosts unlock better audio quality and more customization for a whole community.

Companies use Discord for community support, developer relations and beta programs rather than internal work chat, where Slack and Microsoft Teams dominate with search, SSO, compliance and admin controls. Weak search, the permission model and a consumer-oriented interface can make it hard to run as an official business tool, and access depends on local regulation: Turkey, for example, blocked Discord in October 2024. Slack suits internal teams, Circle and Discourse suit structured, searchable communities, and Telegram suits broadcast-style groups.

Slack is the channel-based messaging platform launched in 2014 by Stewart Butterfield's team and acquired by Salesforce in 2021. It popularized organizing workplace communication into channels by team, project or topic, with threads, direct messages and shared channels that connect separate companies through Slack Connect.

Around messaging, Slack offers huddles for quick audio and video calls with screen sharing, clips, canvases for lightweight documents, lists for tracking tasks and Workflow Builder for no-code automations. Thousands of integrations bring notifications from tools such as Jira, GitHub, Google Drive and Salesforce, and apps let users act without leaving Slack. Slack AI summarizes channels and threads, searches across history and answers questions, and Salesforce's Agentforce brings AI agents into Slack. The free plan hides messages and files older than 90 days and limits integrations, which pushes active teams to Pro; Business+ adds SAML SSO, data exports and a higher uptime SLA, and Enterprise+ supports multiple workspaces, DLP and key management.

Slack fits tech companies, startups and distributed teams that rely on many integrations and fast, informal communication. Constant notifications can hurt focus, and costs add up for large organizations. Microsoft Teams wins in Microsoft 365 companies because it is bundled, Google Chat suits Workspace users, and Discord or Mattermost serve communities and teams that want self-hosting.
