Kaggle is Google's hosted platform for data science notebooks, datasets, and competitions — free to use, but notebooks run on Google's infrastructure with fixed compute limits, and it's built around public competitions and datasets rather than private team collaboration. Teams that want a notebook environment they can self-host, connect to their own data warehouse, and use for everyday analytics work (not just competitions) typically look at open-source notebook tools instead.
FAQ
Is there a free, open-source alternative to Kaggle?
For the notebook environment itself, yes — Deepnote is Apache-2.0 licensed and free to self-host.
What's the best open-source alternative to Kaggle?
Deepnote is the closest match if what you actually use Kaggle for is writing and sharing notebooks rather than entering competitions — it adds SQL blocks and real-time collaboration on top of the notebook format.
