Zero democratizes access to the world's best weather data.
Hypatia Zero visualizes global weather in your browser using WebGPU.
ECMWF runs the world's most accurate weather model four times daily. Since October 2025, this data is openly published under CC-BY-4.0. Zero downloads it directly into your browser—no backend, no accounts, just you and the atmosphere.
Scrub through up to 2 weeks of weather. Watch storms form and dissolve. Every minute interpolated, every layer rendered on the GPU.
The source code can be found on the GitHub repo.
