Richard Hipp, announcing SQLite version 3.39.0 in their forums:
If you prefer, you can experiment with the latest 3.39.0 code directly in your web-browser and without having to download or install anything by visiting sqlite.org/fiddle/. (The page name is by analogy to sites like “JSFiddle” and “SQLFiddle”.)
The page runs a WASM-compiled copy of a recent 3.39.0 build in a sandbox in your web browser. Using controls on that page, you can import database files from your local machine (assuming they aren’t too big), work with them, then export any changes back to your desktop.
