jpm
A fast, small, secure-by-default JavaScript package manager written in Rust — every line coded by Claude Code.
jpm is a JavaScript package manager written in Rust, and it makes a bold claim: up to 15x faster than npm, a ~2 MB binary, and security by default. Install scripts need explicit approval, and fresh versions of a package get a one-day cooling-off period before you can pull them. The story behind it is the real hook. The author directed Claude Code, running Claude Opus 5.5, to write every line — its own TLS and crypto included — then spent five days with the agent installing popular packages and hardening the implementation against real-world breakage. The site is brand new (the repo landed 2026-09-28), and the homepage leads with the honesty the genre needs: 'Every line written by Claude Code. Directed by one engineer. Checked against everyone else's tests.' curated by the VibeFix editors
