vlt

Modern package registry platform built specifically for JavaScript teams.

Overview

vlt is a modern package registry platform built specifically for JavaScript teams. It provides npm-compatible package distribution with a focus on performance, security, and dependency management. The platform delivers 76% smaller package payloads, 73% faster installs, and 38% faster registry performance compared to traditional npm registries.

Beyond speed, vlt emphasizes security and control. It includes automatic malware detection, safer package installation defaults, and the ability to query and enforce policies across your entire dependency graph.
