Best Free Platforms for Data Scientists and ML Practitioners — Hugging Face, Kaggle, Colab & SageMaker Lab
Best Free Platforms for Data Scientists & ML Practitioners: Choose Wisely!
Comparing Hugging Face Spaces, Kaggle Notebooks, Google Colab, and SageMaker Studio Lab
💡 Introduction
As a data scientist or machine learning enthusiast, one of the first decisions you face is where to run your experiments. Should you go with Kaggle, Google Colab, Hugging Face Spaces, or SageMaker Studio Lab? Each of these free platforms offers unique advantages — from GPU power and community support to reproducibility and sharing options.
This post walks you through a practical comparison to help you make the best free choice for your workflow — whether you're tuning models, visualizing results, or deploying demos.
⚖️ Platform Comparison Table
| Feature | Kaggle Notebooks | Google Colab | Hugging Face Spaces | SageMaker Studio Lab |
|---|---|---|---|---|
| Free GPU | Tesla T4 / P100 (30h/week) | T4 (free) / A100 (Pro) | A10G (for selected Spaces) | T4 (up to 4 hours/session) |
| Storage | 20 GB + Datasets | ~15 GB (Drive integration) | 5 GB / Space | 15 GB persistent |
| Best For | Competitions, reproducible ML | Interactive experiments | Deploying models & demos | Stable academic research |
| Environment | Jupyter Notebook | Notebook (Google Drive) | Gradio/Streamlit app | Full JupyterLab IDE |
| Session Limit | 9h per session | 12h (free) / longer (Pro) | Always-on (free tier limited) | Up to 4h GPU session |
| Offline Access | ❌ | ❌ | ✅ (clone via GitHub) | ✅ (project persistence) |
| Ease of Sharing | ✅ Public notebooks | ✅ Shareable links | ✅ Web app deployment | ✅ GitHub integration |
⚙️ Understanding GPU Power
When we say a platform provides a GPU, we mean it offers specialized hardware to accelerate computations — especially matrix operations used in deep learning. Below is a simplified GPU power chart to help you compare performance and suitability.
| GPU Model | Compute Power (TFLOPs) | VRAM | Best For |
|---|---|---|---|
| K80 | ~4.1 | 12 GB | Legacy models, simple ML |
| P100 | ~9.3 | 16 GB | Intermediate deep learning |
| T4 | ~8.1 | 16 GB | Modern models (BERT, CNNs) |
| V100 | ~15.7 | 16–32 GB | Large deep learning training |
| A10 / A10G | ~31 | 24 GB | High-end inference, LLMs |
| A100 | ~70 | 40–80 GB | Massive LLMs, generative AI |
Think of TFLOPs (tera floating-point operations per second) as the “horsepower” of your GPU. Higher TFLOPs = faster training and inference.
🌍 Choosing the Right Platform
- For fast experimentation: Use Google Colab — easy to start, integrates well with Drive.
- For competitions & datasets: Choose Kaggle — reproducible, community-driven, and clean GPU sessions.
- For deployment & sharing: Go with Hugging Face Spaces — ideal for demos and model showcases.
- For research workflows: Try SageMaker Studio Lab — a stable JupyterLab-like IDE with AWS reliability.
Each tool can complement the other — for example, train on Kaggle, validate on Colab, and deploy on Hugging Face Spaces. You don’t need to commit to just one.
