+ 1 Codesphere offers one free GPU workspace per user with 20 GB of storage and a shared GPU — no credit card required. Unlike notebook-only platforms (Colab, Kaggle), Codesphere gives you a full cloud development environment where you can run any workload, not just Jupyter notebooks. The free tier includes 3 workspaces (with GPU on one) and 3 team seats. The catch: free workspaces auto-shutdown after ~60 minutes of inactivity, and GPU availability is limited by demand.

+ 14 Caveats:
No comments on this line yet.
+ 15 • Free workspaces turn off after ~60 minutes of inactivity (no IDE activity). They boot back up in seconds when you return
No comments on this line yet.
+ 16 • GPU availability is constrained — Codesphere has stated they sometimes have more demand than capacity. If you can't get a GPU workspace, try again later or upgrade to paid

+ 17 • The GPU is shared, not dedicated — expect variable performance

+ 18 • Only your initial team gets the 3 free workspace allocation. Additional teams require paid plans

+ 65 • Not just for notebooks — the biggest differentiator vs. Google Colab or Kaggle is that Codesphere gives you a full dev environment. You can build and deploy full applications, not just run experiments

+ 66 • Auto-shutdown workaround — the 60-minute idle timeout applies to IDE activity specifically. A planned "Dev Deployment mode" was announced that would keep workspaces alive when users visit their dev domain, but check if this has shipped

+ 67 • GPU availability is hit-or-miss — if the free GPU slots are full, you'll need to wait or pay. Try signing up during off-peak hours (nights, weekends) for better luck

+ 68 • Good for hobbyists and prototyping — the free tier is best suited for hobbyist projects, learning ML, and quick prototyping. For serious training, use a dedicated GPU cloud (RunPod, Vast.ai, Lambda)

+ 69 • Combine with other free tiers — use Codesphere for development and deployment, and a free GPU provider (Colab, Kaggle, Lightning AI) for heavy compute tasks

+ 70 • $10/month GPU add-on is competitive — if you like the platform, the paid GPU option with "off when unused" billing is very affordable for intermittent workloads
