seenix turns Nix closures into byte-by-byte maps

seenix.dev Visit website

Editorial interest 88/100 Selection signal · not a rating of the site

An interactive browser visualization that lays out every byte of a Nix package closure along a Hilbert curve.

Landing page captured for the 2026-09-18 issue.

For: Nix users inspecting package closures
Worth noticing: NARs are fetched on zoom, decompressed in the browser, and cached locally for later viewing.

Field notes

The page accepts closure data produced by nix path-info, package selections, or linked inputs, then arranges paths in name order so each store path occupies a connected region. At deeper zoom levels, NARs are retrieved from cache.nixos.org or user-supplied caches, decompressed in the tab, and checked against signed hashes. Local browser storage retains fetched NARs and summaries, with a stated 2 GiB file-system limit.
