Dynos are the heart of every Heroku app—lightweight, isolated containers that handle your code, dependencies, and scaling. They are the building blocks that power any Heroku app, from simple to sophisticated. Heroku’s dyno management makes it easy for you to build and run flexible, scalable apps – freeing you from managing infrastructure, so you can focus on building and running great apps.

We’ve transitioned to a Sustaining Engineering model to better serve the customers who rely on us every day. Our mission is simple: to provide the most stable, secure, and reliable environment for your apps and data. We will continue releasing features and functionality that align with our Sustaining Engineering goals and provide a more robust and efficient platform to our customers.
Today we are excited to share three recent enhancements:
Heroku CLI v11 is now available. This release represents the most significant architectural overhaul in years, completing our migration to ECMAScript Modules (ESM) and oclif v4. This modernization brings faster performance, a new semantic color system, and aligns the CLI with modern JavaScript standards.
While v11 introduces breaking changes to legacy namespaces, the benefits are substantial: better performance, improved maintainability, and enhanced usability that simplifies how you manage Heroku resources from the command line.
Modern applications, especially those leveraging AI and data-heavy libraries, need more room to breathe. To support these evolving stacks and reduce developer friction, we’ve increased the default maximum compressed slug size from 500MB to 1GB.
