The developer-centric PaaS for deploying, managing, and scaling modern AI-driven applications.
Heroku remains a cornerstone of the PaaS ecosystem in 2026, offering a high-abstraction layer over AWS infrastructure that allows developers to focus on code rather than server management. Acquired by Salesforce, Heroku has evolved to deeply integrate with the Salesforce Data Cloud and AI Research divisions, making it a premier choice for hosting LLM-powered middleware, Python-based microservices, and complex web applications. Its architecture is built around 'Dynos'—isolated Linux containers that scale horizontally and vertically with a single command or API call. The 2026 market position of Heroku focuses on 'Heroku Flow' for automated CI/CD and 'Heroku Shield' for high-compliance industries like FinTech and HealthTech. While competitors offer lower raw infrastructure costs, Heroku's value proposition lies in its operational efficiency, reducing the need for dedicated DevOps engineers. Its extensive Add-on Marketplace provides managed services for everything from Redis and Postgres to specialized AI vector databases, ensuring that the developer experience remains seamless and highly integrated.
Smart, isolated Linux containers that provide a sandboxed environment for code execution without virtual machine overhead.
