What is Hive Index?

Hive Index is a free, searchable directory of 5,009 online communities organized across 261 topics. Launched in 2021, it solves the problem of finding active, relevant communities without relying on word-of-mouth or luck. Every listing includes member counts, platform details, features, and direct links, making it easy to compare communities at a glance. Users can also submit missing communities or suggest new topics for free.

• Niche enthusiasts – People with specific interests (from entrepreneurship to gaming to fitness) who want curated topic pages listing every relevant community in one place.
• Community builders – Founders or moderators looking to discover how other communities structure their features, platforms, and membership models for inspiration.
