About Kaggle

Kaggle is a web platform where people learn and practise data science and machine learning. Its best-known part is competitions: companies and researchers post a dataset and a scoring metric, and teams submit predictions to climb a public leaderboard, sometimes for prize money. Around that sit a large library of community-uploaded datasets and models, discussion forums, short free courses, and hosted Jupyter-style notebooks that run in the browser with a weekly quota of free GPU and TPU time. Notebooks start from a ready-made Python environment that Kaggle publishes as a Docker image, and an official open-source command-line tool lets you download data and submit entries from your own machine. Using the site is free; there is no paid tier for individuals. It suits students building a portfolio and practitioners who want free compute and benchmark problems, while teams that need private, persistent work environments usually move to Colab, Databricks or their own Jupyter setup. Kaggle has been part of Google since 2017.

Best for: Students and data scientists who want free notebooks, public datasets and ML competitions in one place.
