Go to the Starter Worlds page to see Starter Worlds for all APIs on one page.
These APIs use specific versions of third-party libraries. These APIs will not change in the future, so that all runs will always work. Rather, new APIs will be added.
These APIs are useful for writing JS Worlds for this site:
| API | Uses canvas | Graphics libraries | AB framework | Worlds using this API | Starter Worlds |
| Three (AB 3.0) | Yes | Three.js | Yes | 17 Worlds | Starter Worlds |
| Physics (AB 2.0) | Yes | Three.js, Ammo | Yes | 1 World | Starter Worlds |
| P5 (AB 2.0) | Yes | P5 | Yes | 4 Worlds | Starter Worlds |
| ML5 (AB 1.0) | Yes | P5, ML5 | Yes | 1 World | Starter Worlds |
| Canvas (AB 2.0) | Yes | None | Yes | 2 Worlds | Starter Worlds |
These APIs are useful for porting JS Worlds to this site unchanged:
| API | Uses canvas | Graphics libraries | AB framework | Worlds using this API | Starter Worlds |
| Three (3.0) | Yes | Three.js | No | 3 Worlds | Starter Worlds |
| Physics (2.0) | Yes | Three.js, Ammo | No | 2 Worlds | Starter Worlds |
| P5 (2.0) | Yes | P5 | No | 39 Worlds | Starter Worlds |
| ML5 (1.0) | Yes | P5, ML5 | No | 1 World | Starter Worlds |
| Canvas (2.0) | Yes | None | No | 2 Worlds | Starter Worlds |
| Webpage (2.0) | No | None | No | 4 Worlds | Starter Worlds |
The earlier APIs will exist forever, so the Worlds will run forever. You can go on using the earlier API, and writing Worlds for it, forever.
We expect most Worlds to have APIs in this section. And this is not a problem.
