Hi there - CTO of Rerun here! Rerun is still in beta, but we think it’s already good enough to be useful. It is built on wgpu, Apache Arrow, my own egui.rs library, and it also runs as Wasm in the browser. I'm happy to answer any questions you may have! PS: Thanks for the shoutout fdb!
A video of it working might be really good, it might make it clearer what this does.
