# Supported Runtimes for DigitalOcean Functions Functions are blocks of code that run on demand without the need to manage any infrastructure. Develop on your local machine, test your code from the command line (using `doctl`), then deploy to a production namespace or App Platform — no servers required. Functions supports runtimes across four programming languages: - **Go**: 1.17, 1.20, 1.24, 1.25 - **Node.js**: 14, 18, 22, 24 - **PHP**: 8.0, 8.2, 8.3, 8.4, 8.5 - **Python**: 3.9, 3.11, 3.12, 3.13 To view the list of supported runtimes, run `doctl serverless status --languages`. ## Language-specific Reference [Functions Go Runtime](https://docs.digitalocean.com/products/functions/reference/runtimes/go/index.html.md): Details on developing Functions using Go.
