The Salesforce platform offers a powerful array of tools for customization and building customer-centric experiences, from no-code automation with Flow, Prompt Builder, and Agent Builder, to robust Apex and Lightning Web Components. The art lies in choosing the right blend of these tools to achieve agility, optimize skill sets, and quickly adapt to business demands. Today, we’re introducing a new ingredient to this powerful mix: Heroku + AppLink.

Modern cloud-native architectures are composed of multiple microservices running across dynamic environments. Effectively diagnosing performance issues, bottlenecks, or failures requires comprehensive observability. For this, many organizations look to OpenTelemetry, which provides a standardized approach to capturing and analyzing telemetry data. Fir is Heroku’s next generation cloud platform , designed to offer more modern cloud-native capabilities with flexibility and scalability. It’s built on proven, open-source technologies. Traditional Heroku relied on proprietary technologies, which was appropriate at the time because high-quality open-source alternatives didn’t exist. But now, technologies like Kubernetes and OpenTelemetry are considered best-in-class solutions that are widely deployed and supported…

If you’ve ever deployed an app on Heroku, chances are you’ve used Heroku Postgres — our fully managed, reliable, and scalable Postgres database service. It’s the backbone for millions of applications, from weekend side projects to enterprise-grade systems running in production.
But Postgres, like all software, continues to evolve. With new versions released each year, you gain access to performance enhancements, critical security updates, and powerful new features. Keeping your database up to date isn’t just good practice — it’s essential for long-term stability and success.
That’s why we’re thrilled to share that Postgres 17 is now available on Heroku . And…

Heroku recently made the next generation platform – Fir – generally available. Fir builds on the strengths of the Cedar generation while introducing a new modern era of developer experience. Fir leverages modern cloud-native technologies to provide a seamless and performant platform.
One of the goals we set out to achieve with Fir is to modernize our platform’s observability architecture. Applications being written today are becoming increasingly more distributed and complex in nature. With this increase in complexity, the need for good observability becomes critical. With solid observability practices in place, it becomes possible to gain deep insights into the internal…

The speed and efficiency of the Go programming language make it popular for backend development. Combine Go with the Gin framework —which offers a fast and minimalistic approach to building web applications—and developers can easily create high-performance APIs and web services. Whether you’re working on a personal project or building a production-ready application, Go and Gin make for an attractive stack perfectly suited for lightweight, scalable web development.
Creating a Go/Gin application might seem straightforward: You write a few routes, connect a database, and spin up a local server. But when it comes to deploying your app, things can get tricky.…

SignalR makes it easy to add real-time functionality to .NET web applications—things like live chat, instant notifications, or interactive dashboards. But what happens when your app starts to grow? A single server can only take you so far. At some point, you’ll need to scale out.
In this post, we’ll walk through what it takes to scale a SignalR app to run across multiple servers. We’ll start with the basics, then show you how to use Redis as a backplane and enable sticky sessions to keep WebSocket connections stable. And we’ll deploy it all to Heroku. If you’re curious about what…

Generative AI has been one incredible tool to improve my productivity not only for work but for personal projects too. I use it every day, from generating stories and images for my online role playing games to solving code and engineering problems and building awesome demos. Lately I’ve leaned into Cursor as my go‑to AI coding companion. Its inline suggestions and quick edits keep me moving without context‑switching. Connecting Cursor to my apps through the Heroku MCP Server lets me perform actions like deploying or scaling, without leaving my code editor, making AI a first class citizen in the Heroku…

Many advanced users want to use GitHub Actions with their applications on Heroku. Now there’s a straightforward way to use these great systems together, and to meet strong security and compliance requirements at the same time.
A Solution for GitHub IP Range Restrictions
Heroku is a powerful platform that offers robust CI/CD capabilities and secure, scalable environments for deploying applications. However, GitHub Orgs cannot be configured with Heroku IP ranges, which can be a requirement for some organizations’ security rules. While this is under consideration, we want to share an alternative that leverages GitHub Actions, Heroku’s ability to…
