Show HN: Hyperparam: OSS tools for exploring datasets locally in the browser
platypii Thursday, May 01, 2025For the last year I’ve been developing Hyperparam — a collection of small, fast, dependency-free open-source libraries designed for data scientists and ML engineers to actually look at their data.
- Hyparquet: Read any Parquet file in browser/node.js
- Icebird: Explore Iceberg tables without needing Spark/Presto
- HighTable: Virtual scrolling of millions of rows
- Hyparquet-Writer: Export Parquet easily from JS
- Hyllama: Read llama.cpp .gguf LLM metadata efficiently
CLI for viewing local files: npx hyperparam dataset.parquet
Example dataset on Hugging Face Space: https://huggingface.co/spaces/hyperparam/hyperparam?url=http...
No cloud uploads. No backend servers. A better way to build frontend data applications.
