Load a CSV, get a queryable database that never leaves the machine. Charts are rendered from query results, not from an upload.
How it works
SQLite compiled to WASM, persisted to the Origin Private File System, so a session survives a reload without a server round trip.
Notes
Import is streamed, so a two-hundred-megabyte export does not blow the heap.
Changelog
- v0.9 — OPFS persistence and streamed CSV import.
- v0.5 — First public beta.
