Map of Reddit
116,000 subreddits. 1.5 billion user relationships. One interactive map. Every dot is a community — every cluster is a shared world. The same open-source Vue/WebGL app is built into this site (not embedded in an iframe).

How it works
Communities that share overlapping audiences sit close together — the same idea as our similarity finder, but laid out at the scale of all of Reddit.
Find a subreddit
Use the search bar inside the map to jump straight to any community. Zoom in to read its neighborhood.
Pair with the finder
Spot an interesting cluster on the map, then use our similarity finder for ranked neighbors and graph connections.
How to Navigate the Map of Reddit
Basic Navigation
The map loads with a full view of the Reddit galaxy. Use your scroll wheel or trackpad to zoom in — the closer you get, the more subreddit names become visible. Click and drag to pan across the map. On mobile, use pinch-to-zoom and swipe to navigate.
Finding a Specific Subreddit
Use the search bar to locate any subreddit by name. The map will zoom to its location and highlight it. Once you have found a community, look at its neighbors — they share the most audience overlap with it.
Reading Clusters
Subreddits are positioned by their similarity relationships, not alphabetically or by size. Communities that attract the same users end up in the same neighborhood. This means a tight cluster of subreddits around r/gaming contains communities whose members heavily overlap with gaming content — even if some aren't labeled gaming subreddits at all.
Zoom into any cluster and you will find a micro-ecosystem: a central large community surrounded by smaller, more specialized ones. The structure repeats at every scale, from broad macro-clusters down to individual niches.
Exploring the Edges
The most interesting discoveries often happen at the edges between clusters — where two different interest graphs touch. The boundary between gaming and anime, between personal finance and entrepreneurship, between politics and history — these overlap zones are where the most cross-community activity happens.
What the Map Reveals About Reddit
The Gaming Supercluster
Gaming is by far the largest and most densely connected macro-cluster on the map. It contains thousands of subreddits spanning esports, indie games, retro gaming, game development, specific franchises, and adjacent communities like anime and memes. The sheer density reflects Reddit roots as a platform popular with gamers.
The Politics-News-Worldbuilding Axis
Near the center of the map, political and news communities form a dense, highly cross-linked cluster. These communities have among the highest cross-user participation rates on Reddit — people who post in one political subreddit tend to be active across many of them. Adjacent to this cluster sits a large worldbuilding and history community, connected by shared interest in geopolitics and speculative scenarios.
Science and Technology
Programming, data science, hardware, and science communities form a distinct macro-cluster with relatively few connections to the gaming or entertainment clusters. Within this region, r/programming, r/learnprogramming, r/cscareerquestions, and dozens of language-specific subreddits form a tight sub-cluster that reflects the developer community strong internal cohesion.
Sports and Geography
Sports communities cluster by region and sport type, with clear geographic patterns — North American sports form their own region, football (soccer) communities form a separate European-leaning cluster. Local city subreddits also cluster by geography, forming a real-world geography region distinct from topical communities.
About the Map of Reddit Data
The Map of Reddit was built from 1.5 billion user-community relationships — every instance of a user being active in a subreddit. The similarity algorithm compares these activity patterns across pairs of subreddits to produce a similarity score for each pair.
These scores are then fed into a graph layout algorithm that positions each subreddit in two-dimensional space. Subreddits with high mutual similarity end up close together; unrelated communities end up far apart. The result is a map where position carries meaning — geography is data.
The original dataset and methodology were published by Andrei Kashcha. This edition covers 116,000 subreddits — a significant expansion from earlier versions — reflecting Reddit growth over recent years.
Frequently Asked Questions
- What is the Map of Reddit?
- An interactive visualization that places 116,000+ subreddits on a 2D map based on how much their audiences overlap. Communities whose members tend to participate in both are placed near each other.
- Who made the Map of Reddit?
- The original Map of Reddit was created by developer Andrei Kashcha (anvaka on GitHub). This hosted version is based on his public dataset and methodology.
- Is the Map of Reddit working in 2025?
- Yes — this version of the Map of Reddit is fully functional. The edition here uses an updated dataset covering 116,000 subreddits from 1.5 billion user relationships.
- How is the map different from Reddit's own Explore page?
- Reddit Explore uses topic tags assigned by moderators. The Map of Reddit uses behavioral data — actual user activity patterns — which produces more nuanced and often more surprising community groupings.
- Why does my subreddit appear far from where I expected?
- Position on the map is determined entirely by user overlap, not by topic name or size. A subreddit about cooking might appear near one about homesteading, not near other food-related subreddits, if that is where its actual user base overlaps most.
- Can I find NSFW subreddits on the map?
- The dataset includes communities across Reddit full range. The map renders all subreddits present in the similarity data regardless of content type.
