Bun isn't in the official Ubuntu archives, and the upstream installer pipes a script straight into your shell โ this repository packages Bun 1.3.14 as a proper .deb instead. It's GPG-signed, tracked by apt, upgraded with apt upgrade and removed with apt remove. Add the repository once (below), then run:
sudo apt install bunapt install bunWhat is Bun?
Bun is a fast all-in-one JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It's designed as a drop-in replacement for Node.js with significantly better performance, featuring a built-in bundler, test runner, and package manager all in a single executable.
๐ฅ Key Features of Bun

apt update๐ There is an always-free mirror. deb-free.griffo.io serves packages free forever โ no account, no subscription, at most 2 months behind upstream, security fixes immediately. It currently carries Ghostty, Oh My Posh and Zed; Bun is not one of them, so the repository above is the only way to get it today โ ask and it can be enrolled.
๐ Available Bun Packages
deb.griffo.io provides three different Bun packages to suit different needs:
Metapackage that automatically installs the latest stable bun-one. This is the recommended choice for most users as it ensures you always get the latest stable release.
sudo apt install bunapt install bunLatest stable release of Bun runtime. This package contains the production-ready version with optimizations for performance and stability.
sudo apt install bun-oneapt install bun-oneProfiling-enabled build of Bun with debugging symbols and profiling capabilities. Ideal for development, debugging, and performance analysis. Slightly larger binary with additional debugging information.
sudo apt install bun-profileapt install bun-profile๐ Managing Multiple Bun Versions
You can install both bun-one and bun-profile simultaneously and switch between them using Debian's update-alternatives system:
Install both versions:
sudo apt install bun-one bun-profileapt install bun-one bun-profileConfigure alternatives (done automatically during package installation):
sudo update-alternatives --install /usr/bin/bun bun /usr/bin/bun-one 100
sudo update-alternatives --install /usr/bin/bun bun /usr/bin/bun-profile 90update-alternatives --install /usr/bin/bun bun /usr/bin/bun-one 100
update-alternatives --install /usr/bin/bun bun /usr/bin/bun-profile 90Switch between versions interactively:
sudo update-alternatives --config bunupdate-alternatives --config bunCheck current version:
bun --version
which bunStep 2: Install Bun
sudo apt install bunapt install bunStep 3: Verify Installation
bun --version
bun --help๐ Quick Start Examples
Create a new project:
mkdir my-bun-app && cd my-bun-app
bun initInstall packages (faster than npm):
bun install express
bun add -d @types/expressRun TypeScript directly:
echo 'console.log("Hello from Bun!")' > app.ts
bun run app.tsBundle for production:
bun build ./app.ts --outdir ./dist --minifyRun tests:
bun test๐ง Configuration
Bun can be configured using a bunfig.toml file in your project root or home directory:
# bunfig.toml
[install]
# Configure package manager behavior
cache = "~/.bun/install/cache"
registry = "https://registry.npmjs.org"
[run]
# Configure script runner
shell = "bash"
[test]
# Configure test runner
preload = ["./setup.ts"]โก Performance Benefits
