◈

One CLI, Many SDKs

Manage Node.js, Python, Java, Go, Rust, package managers, `npm:` developer tools, and GitHub Release tools with one command model.

⧉

Cross-Version Deduplication

Installed versions can reuse identical files to reduce duplicate disk use; the implementation guide covers the storage strategy.

⇄

Automatic Fastest Mirrors

Probe official sources and authoritative mirrors, select by speed, and fail over when metadata or artifact downloads fail.

⌁

Reproducible Projects

Generate a platform-aware osdk.lock with exact versions and backend-specific reproduction data; schema 3 records npm tool scope and native-lock identity.

✓

Integrity and Provenance

Verify upstream checksums, enforce strict checksum policies, and validate GitHub Artifact Attestations with Sigstore.

⬡

Offline Reinstall and Shared Caches

Reuse metadata, artifacts, and native package caches; cold offline npm reinstalls also need installer-owned native locks and warmed caches.

Start in three steps

bash

# Install osdk
curl --proto '=https' --tlsv1.2 -sSf \
  https://raw.githubusercontent.com/lejunyang/one-sdk/main/install.sh | sh

# Install Node.js and set the global default
osdk use -g node@20

# Use it directly
node --version
