# vlt

> vlt (pronounced "volt") is a JavaScript package management company started by the creator of npm and former npm core team members, backed by Accel. It ships the open source vlt package manager CLI, the npm-compatible vlt serverless registry (vsr) for Cloudflare's edge, and a hosted registry platform at vlt.io. The hosted registry API at registry.vlt.io is npm-compatible and authentication-gated; self-hosted vsr instances serve an OpenAPI document at /-/api and an interactive reference at /-/docs.

Generated by API Evangelist (2026-07-21, method: generated) from apis.yml and repo artifacts; vlt does not publish its own llms.txt (404 on www.vlt.io and docs.vlt.io).
