Preparing for Shorter SSL/TLS Certificate Lifetimes

The web browser and certificate authority industry is shortening the maximum allowed lifetime of TLS certificates. These changes will improve security on the Web, but you may have to change certificate maintenance practices for apps you run on Heroku.

The good news is that if you’re using Heroku Automated Certificate Management, no changes are required: Heroku already refreshes and updates certificates on your apps according to the new policies.

If you maintain and upload …

Whats New in Heroku AI: New Models and a Flexible Standard Plan

Heroku is introducing significant updates to Managed Inference and Agents. These changes focus on reducing developer friction, expanding model catalogue, and streamlining deployment workflows.

Code Execution Sandbox for Agents on Heroku

Large language models are good at writing code. Data from Anthropic shows that allowing Claude to execute scripts, rather than relying on sequential tool calls, reduces token consumption by an average of 37%, with some use cases seeing reductions as high as 98%.

Untrusted code needs a secure and isolated place to execute. We solved this with code execution sandboxes (powered by one-off dynos), launched alongside Heroku Managed Inference and Agents in May 2025.

Building AI-Powered Observability with Heroku Managed Inference and Agents

If you’ve ever debugged a production incident, you know the drill: IDE on one screen, Splunk on another, Sentry open in a third tab, frantically copying error messages between windows while your PagerDuty keeps buzzing.

You ask “What errors spiked in the last hour?” but instead of an answer, you have to context-switch, recall complex query syntax, and mentally correlate log timestamps with your code. By the time you find the relevant log, you’ve lost your flow. Meanwhile the incident clock keeps ticking away.

The workflow below fixes that broken loop. We’ll show you how to use the Model Context Protocol (MCP) and Heroku Managed Inference and Agents to pipe those observability queries directly into your IDE, turning manual hunting into instant answers.

Heroku and GitHub Enterprise Server: Stronger Security, Seamless Delivery

Today, we are thrilled to announce the General Availability (GA) of the Heroku GitHub Enterprise Server Integration.

For our Enterprise customers, the bridge between code and production must be more than just convenient. It must be resilient, secure, and governed at scale. While our legacy OAuth integration served us well, the modern security landscape demands a shift away from personal credentials toward managed service identities.

An Update on Heroku

Today, Heroku is transitioning to a sustaining engineering model focused on stability, security, reliability, and support. Heroku remains an actively supported, production-ready platform, with an emphasis on maintaining quality and operational excellence rather than introducing new features. We know changes like this can raise questions, and we want to be clear about what this means for customers.

There is no change for customers using Heroku today. Customers who pay via credit card in the Heroku …
