77+A 2D map of the ATProto ecosystem for end-user apps, plotted on two axes:
8899-- **X: User Distance** — Infrastructure → Dev Tools → Middleware → End-User Apps
1010-- **Y: Maturity** — Concept → Prototype → Active → Established
99+- **Y: User Behavior** — Communicate / Discover / Create / Analyze / Moderate / Manage
1010+- **X: Audience Breadth** — Everyone / Community / Creators / Power Users
1111+- **Maturity** (color) — Established (blue) / Growing (green) / Emerging (orange) / Experimental (red)
11121213The map makes gaps visible. Where the grid is empty, no one has built yet.
13141515+## Design decisions
1616+1717+- **End-User Apps only.** Dev Tools deserve a separate map with different axes.
1818+- **No App Store.** No rankings, reviews, stars, or download counts. Every app occupies equal space.
1919+- **Opt-in listing.** Developers choose to be on the map.
2020+- **UI layer, not data layer.** This map consumes data that a community app lexicon produces. It complements directories like [atproto.garden](https://atproto.garden) and [BlueskyDirectory](https://blueskydirectory.com), not competes with them.
