Bun, the fast all-in-one JavaScript and TypeScript runtime and toolkit, preinstalled as a ready-to-use development and runtime workstation. The bun binary, a shared package install cache on a dedicated disk and an offline demo project with an HTTP server and a test are all set up, so you can run, build, test and install within minutes of launch.

Overview
Bun is the fast all-in-one JavaScript and TypeScript toolkit: a single native binary that is a runtime, a bundler, a transpiler, a test runner and an npm-compatible package manager. It runs JavaScript and TypeScript files directly, installs packages quickly, bundles for production and runs your tests, all from one command. This image delivers Bun fully installed and configured as a ready-to-use workstation, so a developer can SSH in and start running, building and testing JavaScript and TypeScript projects immediately, with no setup.
All-in-One JavaScript Toolkit
The bun binary installed at /opt/bun/bin/bun and symlinked onto the system path as bun and bunx, verified against the official release checksum. One command runs your code, installs your dependencies, bundles your app and runs your tests, with TypeScript and JSX support built in and no separate transpiler step. The npm-compatible package manager reads your existing package.json and installs into a fast, shared cache.
Shared Install Cache On A Data Disk
The Bun global install root and package install cache are placed on a dedicated, independently resizable data disk and exported to every login shell, so packages downloaded by bun install are shared across projects and persist on durable storage rather than the operating system disk. The first install in any project pulls packages into the shared cache and every later project reuses them.
Offline Demo Project
A self-contained demo project ships on the image with an HTTP server and a test that use only Bun's built-in APIs, so you can run bun install, bun run and bun test end to end with no third-party dependencies and no cloud credentials and confirm the runtime works the moment you log in. Copy it, point it at your own code and start building.
Run, Build, Test, Serve
Use bun run to execute scripts and TypeScript files directly, bun install to manage dependencies, bun build to bundle for production, bun test as a fast Jest-compatible test runner, and Bun.serve to run a high-throughput HTTP server. Bun reads the package.json and lockfiles your team already uses and integrates cleanly into CI and container images.
Ready To Use
Connect over SSH and run bun straight away. The install cache, demo project and environment are already in place, so the first bun install pulls packages into a shared cache on the data disk and every subsequent project reuses them. Build your own applications or wire the workstation into your pipelines.
