Runtimes
Deploy and scale your code in seconds with Clever Cloud’s managed runtimes, designed for the most popular languages and frameworks.
About Clever Cloud Runtimes
Clever Cloud Runtimes are preconfigured environments that run your code without requiring infrastructure management or manual setup. Whether you use Java, Node.js, PHP, Rust, .NET, or Docker, we provide native, secure, and scalable environments that keep your app available — so you can focus on features.

How It Works
1 Choose where you want to host your application: on our servers in France, on partner servers worldwide, or on your own infrastructure.
2 Push your code to GitHub, GitLab, the console, our CLI, or via API.
3 Clever Cloud automatically detects it.
4 Your app is built, deployed, managed, and maintained continuously.
5 You decide whether to scale manually or automatically.
6 And that’s it!

Frequently Asked Questions
What is a “runtime” on Clever Cloud?
A runtime is a preconfigured environment that knows how to build and run your application. It manages dependency installation, execution, scaling, and monitoring. You just push your code, and it goes live.
Which languages and frameworks are supported?
We support most major languages and frameworks: Java, Node.js, PHP, Python, Ruby, .NET Core, Go, Rust, Scala, Haskell, Elixir, as well as Dockerized or static apps. See each runtime’s documentation for details.
Can I customize the build or run process?
Yes. Most runtimes support environment variables (e.g., CC_RUN_COMMAND, CC_GO_BUILD_TOOL, CC_WEBROOT) and Clever Cloud–compatible build hooks. You can also use a .clevercloud config file in your repo.
How does Clever Cloud detect the runtime?
Our deployment engine automatically detects your project’s language based on its structure and configuration files (package.json, pom.xml, go.mod, etc.). You can also force runtime recognition through the Clever Cloud console or CLI.
How does scaling work?
Clever Cloud supports both manual and automatic horizontal and vertical scaling. You define minimum and maximum instance counts, and we adjust capacity based on load. All runtimes automatically restart in case of failure.
Is there vendor lock-in?
No. You can export your code and leave anytime. If you use Docker, we don’t modify your image. Our pricing is transparent as well: no hidden quotas or usage penalties.
Where are my apps hosted?
You can choose between our servers in France and partner datacenters worldwide (Canada, Poland, Australia, Singapore, Dubai, London, etc.), depending on performance and compliance needs. All hosting complies with European data protection standards (GDPR) and is located in jurisdictions free from extraterritorial laws.
How does pricing work?
You only pay when your app is running. You can pause it anytime. Pricing adapts whether you use manual or automatic scaling. You can pay upfront with credits or on a pay-as-you-go basis.
