Playground

A real fenecdb instance, running in this tab. The engine is the same 338 KB WebAssembly module the rest of the site uses, on a worker thread. Nothing is uploaded and nothing is stored — close the tab and the database is gone.

The collection is seeded with 400 short notes across eight topics, each carrying a 64-dimension vector, indexed with @hnsw(cosine). Write whatever you like — create collection, put, del, compact all work. The full language is in the FenecQL reference.
