Free Colab Alternatives
Four verified free alternatives to Google Colab - Kaggle, Lightning AI, Paperspace and Hugging Face ZeroGPU - with real GPU hours, limits and card rules.
Google Colab’s free tier gives you a notebook, but its own FAQ says access to expensive resources like GPUs is heavily restricted, the GPU types vary over time, and the usage limits are neither guaranteed nor published; notebooks run at most 12 hours and idle runtimes time out. The verified options below publish more. Kaggle gives up to 30 hours a week of GPU and 20 of TPU; Lightning AI includes up to 30 free credits, about 80 GPU hours on interruptible machines; Paperspace offers free basic GPU instances with a 12-hour notebook limit; and Hugging Face ZeroGPU gives 5 GPU minutes a day for Gradio Spaces. Every row is a live offer from the same catalog as the free AI coding tools directory, re-checked monthly. The free GPU for AI guide and free GPU cloud comparison go further.
| Option | What is free | Card | The catch |
|---|---|---|---|
| Kaggle Free GPU and TPU Notebooks | Free Kaggle notebooks: 30 hours/week of GPU and 20 hours/week of TPU | no card | Catch: Phone verification is required to unlock GPU/TPU accelerators; weekly quotas reset weekly and can vary with demand, and sessions are capped at 9-12 hours. |
| Lightning AI Free Plan | Up to 30 free credits (about 80 GPU hours) and 1 free Studio | no card | Catch: Only 5 free credits on registration out of up to 30, credits expire after 12 months, and GPU machines are interruptible. |
| Paperspace Gradient Free GPU Notebooks | Free basic GPU notebooks and 5 GB storage on Paperspace | card | Catch: Free-tier machines are basic instances only — paid GPU instances bill per hour on top of the plan, storage overage is $0.29/GB/month, and only public projects are included. |
| Hugging Face ZeroGPU Free GPU Access on Spaces | ZeroGPU dynamically allocates NVIDIA RTX Pro 6000 Blackwell GPUs to Gradio | no card | Catch: Hosting needs a verified email and a 30+ day account; free users get 5 GPU minutes a day, Gradio only. Outside ZeroGPU, new Gradio or Docker Spaces need PRO. |

Frequently asked questions
- Is Google Colab free?
- Yes, with a Google account, but the free tier is restricted. Colab’s FAQ says GPU and TPU availability varies over time, access to expensive resources like GPUs is heavily restricted on the free tier, limits are not guaranteed or published, and notebooks run at most 12 hours depending on availability. Colab Pro, Pro+ and Pay As You Go add compute by compute-unit balance. This was read from Colab’s FAQ on November 1, 2026.
- What is the best free alternative to Colab?
- Kaggle, if you want a published quota: up to 30 hours a week of NVIDIA GPU and 20 hours a week of TPU v3-8, with 12-hour GPU sessions and no card. Phone verification is required to unlock the accelerators. Lightning AI is the pick for a persistent Studio, with about 80 GPU hours on interruptible machines.
- Which free Colab alternatives need a credit card?
- Only Paperspace: its Individual Free plan asks for a card, and paid GPU instances bill per hour on top. Kaggle, Lightning AI and Hugging Face ZeroGPU do not.
- Can I train a model on these free GPUs?
- Small runs, yes. Kaggle sessions cap at 9 to 12 hours, Lightning AI machines are interruptible and its credits expire after 12 months, and Paperspace notebooks shut down after 12 hours. ZeroGPU is for running Gradio demos, with 5 GPU minutes a day, not for training.
