I was a Data Scientist for 10 years before becoming a quadriplegic. For the past 3 months, I built VibeETL from scratch: A lightning-fast, visual Alteryx alternative powered by Polars & React Flow.

In three linesVibeETL: open-source visual ETL platform built in 3 months by former data scientist. Polars + Rust backend, React Flow frontend with native BFS layout algorithm. Zero external dependencies, sandboxed Python execution (30s timeout). Lightweight Alteryx alternative.
