How To Set Up a Staging Environment on Heroku in 3 Easy Steps

Moving fast should not mean breaking things for your users. While testing on localhost is a good start, you need a near identical replica of production to catch any bugs before your code goes live. That is where a staging environment comes in. Heroku pipelines handle the infrastructure layout for you, keeping your deployment workflow clean and automated.

Securing Heroku CLI Credentials with System Keychain Storage

Beginning in version 11.8.0, we will be improving the security of the Heroku CLI by storing authentication credentials in your system keychain by default. The Heroku credential manager makes use of OS-native secure storage tools with interfaces designed for sensitive data while maintaining compatibility with existing developer workflows.

A 15-Second Health Check for Your Heroku Connect Data Pipeline

Heroku Connect is a fully managed, bidirectional data sync service between Salesforce and Heroku Postgres that lets developers read and write Salesforce data using standard SQL. The sync is straightforward to set up and operates smoothly in the background, but when a field does not update as expected or data seems to lag, you do not need to guess what went wrong.

Heroku March 2026 Update

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:

Modernizing the Command Line: Heroku CLI v11

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.

Bigger Slugs and Greater Build Timeout Flexibility

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.
