Lightning

Lightning AI is a browser-based, cloud platform for AI developers, ML engineers, researchers, and enterprises to build, train, scale, and serve models in a persistent workspace with zero setup.

Key capabilities include:

• Unified AI workspace for data preparation, model development, distributed training, and app deployment in one cloud environment
• Real-time collaboration with multiplayer editing for remote teams working on the same code and experiments
• GPU training and scaling with free GPU access (up to 22 GPU hours/month) and automated scale-out to multi-node, multi-GPU workloads
• Modular integrations that plug into common ML tooling, including PyTorch Lightning, Fabric, TensorBoard, and Weights & Biases

Pricing: Freemium, Free plan available; Pro at $20/month billed annually (includes 40 monthly credits and multi-GPU support); Enterprise with custom pricing (unlimited GPUs, SOC2 compliance, dedicated support).

Notable for being built by the creators of PyTorch Lightning, with enterprise options such as RBAC, private cloud deployment, and compliance support (including SOC2 and HIPAA), plus availability on AWS Marketplace and support for modern NVIDIA GPUs (including A100s/H100s).
