Frequently Asked Questions
Can RunAnywhere be used for cloud-only inference?
Yes, it supports cloud routing (OpenRouter, vLLM, etc.), but its strength is on-device inference.
Does Spider Cloud offer a free tier?
Yes, it has a free tier with limited credits; paid plans start at pay-as-you-go with no monthly subscription required.
Which tool is better for a privacy-focused healthcare app?
RunAnywhere, because inference stays on-device, avoiding sending patient data to the cloud.
Can Spider Cloud extract data from JavaScript-heavy sites?
Yes, its Browser Cloud with stealth anti-detection and Browser AI commands can handle dynamic content.
Does RunAnywhere support NVIDIA GPUs or CUDA?
No, its custom kernels target Apple Silicon and Qualcomm NPUs; cloud routing can be used for NVIDIA, but there is no direct CUDA support.
Is there an open-source version of Spider Cloud?
Yes, the core engine is open-source on GitHub, allowing self-hosting.
Can RunAnywhere run speech-to-speech on-device?
Yes, MetalRT now supports native speech-to-speech with 1.68s end-to-end latency (1.52x faster than mlx-audio).
What integrations does Spider Cloud support for AI agents?
It integrates with LangChain, LlamaIndex, CrewAI, FlowiseAI, AutoGen, Agno, and Dify, plus cloud storage connectors.
