Node.js v20 Minimum Version Requirement

Back to the Changelog

FlowFuse v2.24.0 requires Node.js v20 or higher. If you are running an older version, you will need to upgrade Node.js before updating FlowFuse.

Node.js v18 reached end of life in April 2025 and no longer receives security updates. This change ensures FlowFuse continues to run on a supported and secure runtime.

To check your current version, run node --version.
