Node.js 25.0.0 and 22.21.0 now available
Change effective on 23 October 2025
Node.js versions 25.0.0 and 22.21.0 have been made available for builds on Heroku. For additional information, please see our article on Node.js Support.
Applications running Node.js v25 using the heroku-24 stack in Private Spaces may experience app boot crashes in production. This is because Node.js v25 required the libatomic1 library to be added to the recently updated Heroku-24 base image (see changelog #3433) and base images can take longer to roll out to Private Spaces.
