Reddit runs a community-of-communities platform with 443m weekly active users and over 100,000 subreddits, working on social media, discussion forums, and content moderation tooling.
Reddit operates an online community platform in which millions of people gather daily for authentic conversations about shared interests, organised as a community of communities. The platform reports 443 million weekly active users, with millions of participants arriving each day. Topic-based communities, known as subreddits, number over 100,000 active units and span subject matter from niche hobbies to breaking news, covering verticals such as gaming, science and research, news, and local community organising.
The company's technical work spans online community platforms, social media, content moderation tooling, and interest-based discussion forums. Alongside the core Reddit platform and subreddit structure, its product areas include moderator tools and participation features - investments aimed at helping moderators build healthy community spaces and at lowering the barrier to taking part. Engineering effort is therefore directed at both the systems that carry large-scale conversation and the tooling that governs it.
Reddit describes its mission as building "the heart of the internet", with an emphasis on openness, authenticity, and genuine conversation as platform values. The stated focus is on helping communities thrive and on forming meaningful relationships, supported by continued investment in community health through moderator support tools.
