Node.js is an open-source, cross-platform JavaScript runtime environment.
For information on using Node.js, see the Node.js website.
The Node.js project uses an open governance model. The OpenJS Foundation provides support for the project.
Contributors are expected to act in a collaborative manner to move the project forward. We encourage the constructive exchange of contrary opinions and compromise. The TSC reserves the right to limit or block contributors who repeatedly act in ways that discourage, exhaust, or otherwise negatively affect other participants.

Node.js follows semantic versioning.
- Alpha: Under active development where semver-major changes are allowed.
Each October, a new release line (for example, Node.js 27) branches off
mainand receives Alpha releases (for example,27.0.0-alpha.0.0.0) for 6 months, then are promoted to Current (see below) each April. Alpha releases are signed, tagged, and tested through CITGM, but their API and ABI may change between releases. They are intended for library authors and CI pipelines, not for production use. - Current: Under active development, no semver-major changes allowed. Node.js releases a new major version once a year, in April. Releases stay Current for 6 months, then convert to LTS (see below) each October. Their ABI may change between releases. They are intended for library authors and CI pipelines, not for production use.
- LTS: Releases under Long Term Support, with a focus on stability and security. Only changes that have been on Alpha or Current release for two weeks can be backported to a typical LTS release. Every major version becomes an LTS release, and receives 30 months of LTS support, for a total of 36 months from its first Current release to End-of-Life. LTS release lines have alphabetically-ordered code names, beginning with Node.js 4 Argon.
