Heroku provides services and tools to build, run and scale web apps. We enable flow—for developers to focus on the design and craft of compelling apps.
Powerful platform built by developers for developers that let you focus on building great apps.
Build and Run Your Apps, Your Way.
Heroku supports Ruby, Node.js, Python, Java, Go and PHP so you can use the languages you already know to build and deploy apps on Heroku.
Build: Once you push your application source code, Heroku prepares it for execution by retrieving the necessary dependencies specific to the frameworks and languages you use in your app. Heroku supports Ruby, Node.js, Python, Java, Go and PHP by default, but you can also choose another language by using a custom buildback.
Config: Heroku lets you manage environment-specific configurations (such as credentials for backing services) separately from your source code for greater safety and portability. In Heroku, this data can be managed with config vars, which are made available to your running application as simple environment variables.
Run: Sometimes you want to run one-off dynos on your app—run a script in your app's environment, use your app's console, etc. Using heroku run, you can quickly spin up a one-off instance of your app environment to run ad-hoc commands.
