Google Colab is Google's free, cloud-hosted Jupyter notebook environment, widely used for quick Python experimentation and light ML work. It's convenient, but notebooks and compute run on Google's infrastructure, GPU access is metered and can be throttled or revoked without warning, and real-time collaboration is more limited than a dedicated tool built for it.
Deepnote is the open-source-friendly alternative worth a look if you want notebook collaboration closer to a Google Doc, plus native SQL blocks, without being tied to Colab's compute limits.
FAQ
Is there a free, open-source alternative to Google Colab?
Deepnote is Apache-2.0 licensed and available to self-host, unlike Colab's fully closed, Google-hosted notebook environment.
What's the best open-source alternative to Google Colab?
Deepnote is the strongest pick if real-time multi-user collaboration and built-in SQL blocks matter more to you than Colab's tight Google Drive integration.
