Heroku

About Heroku

Heroku is a cloud platform-as-a-service for building, deploying, and scaling web applications. Apps run inside managed containers called dynos, and the platform includes managed data services such as Heroku Postgres and a Redis-compatible key-value store. Deployment is git-based (e.g., "git push heroku main"), with features including GitHub integration for review apps and branch deploys, Heroku Flow for continuous delivery, fast rollback for code and Postgres data, and app metrics for monitoring runtime performance.

The platform officially supports Node.js, Ruby, Java, PHP, Python, Go, Scala, Clojure, and .NET, with additional language support available through third-party buildpacks. It is extensible through Heroku Elements, which includes over 150 third-party add-ons and 380+ open source buildpacks. Heroku Teams provides tools for managing people, app-level permissions, and billing for collaborative software delivery.

Heroku also offers Heroku AI, which provides managed inference and agents accessible via commands like "heroku ai:models:create", along with support for Model Context Protocol (MCP). The platform maintains PCI, HIPAA, ISO, and SOC compliance certifications and offers an Enterprise tier for larger organizations, along with tiered support options ranging from Standard to Signature.
