About the project

Bun is JavaScript runtime and package manager focused on startup speed. The maintainers own the project, choose releases, and publish their own documentation. This page records a few things worth knowing before you begin.

The project is run by its own contributors rather than by a company. Release cadence, supported platforms and documentation are all decided by the team behind it.

Typical distribution routes

Projects of this kind are usually reached through the operating system's package index, through a language-specific registry, or by building the published source tree. Which route applies depends on the platform and on the maintainers' own guidance.

Before you start

It is worth checking which platforms the current release targets. Support windows differ, and the newest version is not always the one that fits an older machine.

Afterwards

If the outcome differs from what you expected, the cause is nearly always resolution rather than the project itself — an older copy, a different channel, or a stale cache.
