Spider Cloud and Forge CLI serve completely different needs: Spider Cloud is a web data extraction API for AI agents, while Forge CLI is a GPU kernel optimizer for PyTorch models. If you need real-time web data for RAG or LLM context, Spider Cloud's freemium model and browser AI commands are the right choice. If you're an ML engineer maximizing inference speed on datacenter GPUs, Forge CLI's automated kernel generation can deliver 2–5x speedups over torch.compile, but requires contacting sales for pricing.
