Most RAG pipelines ship raw, sensitive documents over the wire to cloud services just to get them parsed, scrubbed of PII, chunked, and vectorized. BitVanes is a zero-trust, local-first ETL engine designed to solve this. It’s written in Rust, spits out Apache Arrow RecordBatches, and compiles to both a native CLI and WebAssembly so you can run the entire pipeline directly in a browser sandbox. I ve got the wasm version at the posted url. Core and cli are on github.I d love to get your thoughts on the architecture, particularly around using Arrow (it s my first time using AA, I m coming from capnp), or the Rust-to-JS design for pdfs to keep the wasm package reasonable.I d like to crates the package once I ve had some people kick the tires and I get it ironed out.
