OnnxStream vs Spider Cloud
Side-by-side comparison of features, pricing, and ratings
OnnxStream or Spider Cloud: which should you choose?
| Dimension | OnnxStream | Spider Cloud |
|---|---|---|
| Primary Use Case | Running large ONNX models (LLMs, Stable Diffusion) on low-RAM devices (Raspberry Pi) | Web crawling, scraping, search, browser automation for AI agents and RAG |
| Key Feature | Streaming model loading: run SDXL in 298MB RAM or Mistral 7B on Raspberry Pi Zero 2 | 100K+ URLs per request, Silk AI extraction, Browser AI commands (Act/Extract/Observe) |
| Deployment | On-device (edge, browser via WASM, embedded) | Cloud API and self-hosted open-source option |
| Output Formats | ONNX model inference output (text, images, etc.) | Markdown, HTML, JSON, JSONL, CSV, XML, plain text, screenshots |
| Best For | Hobbyists and engineers running AI on constrained hardware | Developers needing real-time web data for LLM applications |
If you need to feed your AI agent fresh web data at scale, Spider Cloud is the clear pick—it’s built for that. If you want to run Mistral 7B on a Raspberry Pi or keep inference entirely on-device, OnnxStream is uniquely suited. They serve completely different problems; choose based on whether your bottleneck is data acquisition or hardware constraints.
OnnxStream streams ONNX model weights from disk so large models like SDXL and Mistral 7B run on tiny-RAM devices.

Spider Cloud is a scraping, crawling, and web search API that returns clean markdown or JSON for AI agents and RAG pipelines.
Visit WebsiteWho should pick OnnxStream, and who should pick Spider Cloud?
- AI Agent DeveloperPick: Spider Cloud
Spider Cloud's six API endpoints, Browser AI commands, and Silk extraction model are purpose-built for agents that need to scrape, search, and interact with websites in real time. OnnxStream doesn't address web data needs.
- Edge AI HobbyistPick: OnnxStream
If you want to run Stable Diffusion or Mistral on a Raspberry Pi Zero 2, OnnxStream's streaming model loading is the only viable option. Spider Cloud requires internet and a cloud API.
- RAG Pipeline BuilderPick: Spider Cloud
Spider Cloud's search endpoint and live web search integration (March 2026 news) directly feed current data into RAG pipelines, reducing pipeline time from hours to minutes as shown in its case study.
- Privacy-Focused UserPick: OnnxStream
OnnxStream's WASM bindings let Whisper or other models run entirely in-browser with no server, ensuring data never leaves the device. Spider Cloud sends requests to its cloud API.
- High-Volume ScraperPick: Spider Cloud
Spider Cloud's ability to crawl 100K+ URLs per request and its flat-rate Unlimited plan (July 2026) make it cost-effective for massive scraping operations. OnnxStream cannot scrape the web.
Frequently Asked Questions
OnnxStream vs Spider Cloud: which should you choose?
If you need to feed your AI agent fresh web data at scale, Spider Cloud is the clear pick—it’s built for that. If you want to run Mistral 7B on a Raspberry Pi or keep inference entirely on-device, OnnxStream is uniquely suited. They serve completely different problems; choose based on whether your bottleneck is data acquisition or hardware constraints.
Can OnnxStream run on a GPU?
OnnxStream is CPU-focused with XNNPACK acceleration; it does not mention GPU support in the provided data. For GPU inference, other frameworks like TensorRT or ONNX Runtime are more appropriate.
Does Spider Cloud support PDF scraping?
The provided data lists output formats (markdown, HTML, JSON, etc.) but does not explicitly mention PDF. It may convert PDFs via its scrape endpoint, but this is not confirmed.
What is the latency of Spider Cloud's API?
The data does not specify latency. The service claims 99.9% success rate, but response times depend on target site speed and request complexity.
Can OnnxStream run on a smartphone?
OnnxStream supports ARM architecture, so it could theoretically run on mobile devices, but the data does not provide specific smartphone benchmarks or integration details.
Does Spider Cloud offer a free tier?
Spider Cloud is freemium, but the data does not detail exactly how many free credits or pages are included. It mentions a pay-as-you-go model starting at $0.03/1K pages.
Is OnnxStream compatible with PyTorch models?
OnnxStream uses ONNX format. PyTorch models can be exported to ONNX, so they are compatible after conversion. The project includes an onnx2txt converter for text-based representation.
