Nebulaproxy → GPU reconstruct

Send 5%. Rebuild 100%.

Nebula stores a tiny proxy of every image. The browser reconstructs full quality on the user's own GPU. Your bandwidth drops by 90%. Your users see no difference.

How it works

  1. Your server stores a 5% proxy — a tiny, lossy version of the original.
  2. The browser downloads the proxy instead of the full file.
  3. WebGPU runs a Lanczos-3 resample + unsharp mask to restore detail.
  4. The user sees a sharp image. You paid for 1/20th of the bytes.
