BVMBun Version Manager

The native, zero-dependency version manager for Bun.

🚀 Zero Latency

Shim-based design ensures ~0ms shell startup overhead. No more slow terminal inits.

BVM manages its own isolated Bun runtime, ensuring stability even if your system Bun is broken or missing.

Automatically detects your region and picks the fastest registry (npmmirror/npmjs).

curl -fsSL https://bvm-core.pages.dev/install | bash

irm https://bvm-core.pages.dev/install | iex

npm install -g bvm-core@latest

Method	Best for	Notes
Shell (macOS/Linux)	Most users	Fastest mirror + auto setup
PowerShell (Windows)	Windows dev	Same flow as Unix installer
NPM	Already using Node	Runs postinstall; reopen terminal may be needed

Having trouble with global isolation?

If tools still come from ~/.bun, run bvm setup and verify which bun points to BVM shims.
