Ubidots supports the following runtime versions:

Language	Versions
Python	3.9, 3.11, 3.13, 3.14
Node.js	20, 22, 24

Layers

Each runtime version is offered in one or more layers. Each layer includes a specific set of libraries and capabilities.

• Lite: The lightest option. It offers a minimal environment that is fast and efficient.

• Base: A step up from Lite. It includes more libraries for broader functionality.

• Full: The most complete general-purpose option. It is available only for Python runtimes on Enterprise licenses or above.

• ML Inference: Runs pre-trained machine learning models (TensorFlow Lite and ONNX). Python only.

• ML Classical: Trains and runs classical machine learning and statistical models in the function itself (scikit-learn, statsmodels). Python only.

The ML runtimes are enabled per account. To enable them, reach out to our support team.

The following table shows which layers are available for each runtime version:
