- Worth noticing
- The page says choices are logged in-browser and replayed into ClickHouse; exported saves use JSONEachRow.
Field notes
The page says it stores each line and choice as an event in browser storage, then replays that log into ClickHouse compiled to WebAssembly. It describes Metrics, Traces, and Logs as views over one table, with a read-only shell for queries and a three-second limit. Saves can be exported as JSONEachRow or imported; the page also displays a “CLIENT UNSUPPORTED” warning.
