ViewKit – An interactive tool to view dataset files

I'm an ML/Robotics researcher and constantly deal with HDF5, Parquet, and Zarr files. Personally, I love the myHDF5 viewer, but there's no good equivalent for Parquet and Zarr, and switching between different sites also gets really annoying. So, I built a tool that provides a unified solution: ViewKit

For now, it supports viewing HDF5, Parquet, and Zarr files, but I'm hoping to add more depending on what people find useful! Everything is loaded and parsed locally in your browser (WebAssembly + JS), so your data never leaves your machine. It's also built to remain responsive on big files via efficient reading, caching, and prefetching. From using it, traversing through data files actually seems faster than existing solutions like myHDF5. It also supports some common data types that existing viewers don't support (e.g. float16, complex numbers for HDF5).

It's free to use with no sign-up required. I'd love for people to try it out!

I'd appreciate any feedback (feel free to comment or send a message through the website). Looking forward to supporting additional features/file formats that the community finds useful!
