How I Improved My Productivity with Cursor and the Heroku MCP Server

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…

How to Add the Moesif API Observability Add-On to Your Heroku Applications

With API-driven applications being increasingly common, understanding how your APIs are performing is crucial for success. That’s where the combination of Heroku and Moesif allows developers and their organizations to step up their observability game. In this blog, we will quickly examine how you can integrate Moesif with your Heroku app to begin monetizing and analyzing your API traffic. Let’s kick things off by taking a brief look at both platforms.

Using GitHub Actions with Heroku Flow for additional Security Control

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 run arbitrary…

Simplifying JVM App Development with Heroku’s Buildpack Magic

Heroku’s commitment to developer productivity shines through in its powerful buildpack system. They handle the heavy lifting of building your app, letting you focus on what matters most: writing code. A prime example is the Heroku Java buildpack, a versatile tool that simplifies deploying Java applications, especially those built with popular frameworks like Spring Boot, Quarkus, and Micronaut. One of the core strengths of Heroku buildpacks is their automatic nature. They intelligently detect your application’s language and framework, fetching the necessary build tools and configuring the Heroku platform to run your app seamlessly. This means no more wrestling with server…

Pumas, Routers & Keepalives—Oh my!

This week, Heroku made Router 2.0 generally available, bringing features like HTTP/2, performance improvements and reliability enhancements out of the beta program! Throughout the Router 2.0 beta, our engineering team has addressed several bugs, all fairly straight-forward with one exception involving Puma-based applications. A small subset of Puma applications would experience increased response times upon enabling the Router 2.0 flag, reflected in customers’ Heroku dashboards and router logs. After thorough router investigation and peeling back Puma’s server code, we realized what we had stumbled upon was not actually a Router 2.0 performance issue. The root cause was a bug in…

Building Supercharged Agents with Heroku and Agentforce

Heroku is a powerful general-purpose PaaS offering, but when combined with the broader Salesforce portfolio, it excels in unlocking and unifying customer data, regardless of its age, location, size, or structure. One of the key reasons why Salesforce customers turn to Heroku is when they require such data to be securely linked to high-scale experiences, such as consumer web or mobile apps, or when they need scalable compute resources to access and analyze more intricate and complex data in real time. In this blog, we’ll explore how to supercharge Agentforce by leveraging one of the ways in which the Heroku…

Testing a React App in Chrome with Heroku CI

When building web applications, unit testing your individual components is certainly important. However, end-to-end testing provides assurance that the final user experience of your components chained together matches the expected behavior. Testing web application behavior locally in your browser can be helpful, but this approach isn’t efficient or reliable, especially as your application grows more complex. Ideally, end-to-end tests in your browser are automated and integrated into your CI pipeline. Every time you commit a code change, your tests will run. Passing tests gives you the confidence that the application — as your end users experience it — behaves as…

Data Residency Concerns for Global Applications

Compliance Is Possible with the Right Provider Because today’s companies operate in the cloud, they can reach a global audience with ease. At any given moment, you could have customers from Indiana, Indonesia, and Ireland using your services or purchasing your products. With such a widespread customer base, your business data will inevitably cross borders. What does this mean for data privacy, protection, and compliance? If your company deals with customers on a global — or at the very least, multi-national — scale, then understanding the concept of data residency is essential. Data residency deals with the laws and regulations…
