Thanks for sharing! This feature uses DuckDB-Wasm under the hood. Here’s the equivalent using DuckDBClient, which is handy if you want to join multiple datasets. observablehq.com/d/aff4d0….

When DuckDB-Wasm was launched in 2021, databases couldn't be persisted: everything lived in the Wasm heap and vanished when the tab closed. Now, DuckDB-Wasm can use the Origin Private File System (OPFS) in modern browsers as a storage backend. @carlo.piovesan.io & Geertjan Wielenga show you how:

Persistent Databases in the Browser with DuckDB-Wasm and OPFS

DuckDB-Wasm can open a persistent database file in the browser's Origin Private File System (OPFS). This post shows how, and when data reaches disk.

The #webR and #DuckDB OPFS stuff I found today was too good not to poke at, especially since they have absolutely nothing to with "AI", "LLMs" or "agents". Plus, I rly needed to get back some @webawesome muscle memory. This is a git repo with two thin web […] [Original post on mastodon.social]
Landing page headed "OPFS from the browser: DuckDB and R", explaining that the Origin Private File System is a per-origin sandboxed filesystem with random-access reads and writes. Two cards follow. The DuckDB-Wasm card opens a database at opfs://analytics.duckdb, inserts rows, checkpoints, caches an aggregate as Parquet, and downloads the .duckdb file, with no SharedArrayBuffer needed. The webR card mounts /opfs as an Emscripten filesystem and uses write.csv and read.csv against it, and needs cross-origin isolation. Each card has a button to open its demo.
The DuckDB-Wasm demo page after a page reload. Buttons run the steps: open database, insert a row, count rows, load remote orders, write and read a Parquet cache, download the .duckdb file, clear OPFS. The log below shows the reopened database already holding 13 rows in the observations table and 15,000 rows in orders, so both survived the reload. Two more inserts follow, each checkpointed. The orders table loads from OPFS in 96 milliseconds with no HTTP fetch, the Parquet cache is written to opfs://cache/monthly_totals.parquet and read back as five priority totals, and the database file downloads at 1,060,864 bytes.
The webR demo page. Buttons boot webR and mount /opfs, append a run, read the CSV, list /opfs, and clear OPFS. The log shows webR booting, the 12,355-byte filesystem plugin installing, and /opfs mounting. Five appends grow runs.csv from 21 to 25 rows, and the R data frame prints its last five rows with timestamp, host, and latency columns. The final directory listing shows analytics.duckdb at 1,060,864 bytes, its write-ahead log, the cache directory, and runs.csv at 1,123 bytes, so the R demo and the DuckDB demo share one origin's OPFS.

whoa. #DuckDB works with OPFS (Origin Private File System) — duckdb.org/2026/09/18/opf… and, so can #WebR! — github.com/seanbirchall/w… i.e., load a remote file once and persist to sandboxed private storage accessible by the browser So […]

James Hall's case studies make the edge argument practical: WebGPU handles model execution while DuckDB queries locally. When inference stays on device, privacy and latency stop being tradeoffs and become properties you can design for. #Cloud #DataLeadership
