Every package is already installed
omnibin is a FUSE filesystem that exposes every binary ever shipped by nixpkgs on the $PATH, with nothing installed and 0 bytes on disk until read. It leverages Hydra's .ls metadata and nixpkgs-multiverse to lazily fetch and unpack NARs on demand, providing 881,933 binaries including versioned forms like python3@3.6.2. The tool works via CLI, Docker image, and NixOS module.
- for who
- Developers, system administrators, and AI agents who want instant access to any package without installation.
- why now
- New omnibin project offers instant on-demand access to 881,933 Nix binaries, perfect for agents.
- what changes
- No more per-package installation or base image selection; every binary is available on demand and fetched lazily.
- to do
- Run nix run github:fzakaria/omnibin, use the Docker image fmzakari/omnibin, or enable the NixOS module to have all packages available immediately.

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
