What it does
Heroku Platform is a managed application runtime built around dynos, its container units for running application processes. Developers can deploy supported languages through Git, GitHub, or CI tools, then manage apps from the web dashboard or CLI. Heroku operates the runtime and its underlying systems, while the customer chooses the app's process layout, configuration, and resource tier. The platform also offers logs and operational controls, with more advanced scaling features depending on the dyno tier.
Push an application to a dyno
For a small Node.js service, the official getting-started guide starts with a verified Heroku account, Git, Node.js and npm, and the Heroku CLI. It walks through creating an app and pushing the local main branch to the heroku Git remote; the platform then detects the language buildpack, builds the app, and starts the process declared for web traffic. The guide's example commands include heroku create --stack heroku-26 and git push heroku main. They are documented examples, not commands run for this listing. The CLI can also follow the aggregated log stream with heroku logs --tail.
Heroku suits application deployments where a team wants a managed runtime rather than a virtual machine to patch. A Procfile can declare web and background-worker process types, and the platform provides integrated data add-ons and an operational dashboard. Those features do not remove the need to design app processes and select suitable capacity: dyno sizes and capabilities differ, and autoscaling is available on applicable tiers.
Check the guide's platform generation
The linked Node.js tutorial explicitly targets Cedar, which it describes as the legacy generation. It points to a separate Fir guide and says Fir is currently available only to Heroku Private Spaces. Confirm which generation your account can use before following a tutorial. Pricing is organized around paid monthly dyno tiers and separate data services, so estimate the app's process count and attached services in the current pricing page rather than treating one dyno price as a complete deployment budget.
Strengths
- The managed runtime builds and runs supported language applications without requiring customers to operate the host servers.
- Git, GitHub, and CI-based delivery paths support an app-centric deployment workflow.
- The platform combines aggregated logs with metrics, threshold alerts, and tier-dependent scaling controls.
Watch out for
- The official Node.js getting-started guide targets legacy Cedar, while its Fir path is limited to Private Spaces.
- Capacity and operational features depend on the selected paid dyno tier, and data services are priced separately.
Best for
- Deploying a web application from a Git repository without managing virtual machines
- Running web and background processes on a managed application runtime
- Teams that want app logs and operational controls integrated with deployment
