Spider Cloud and ONNX serve entirely different purposes. If you need to extract web data for AI agents or RAG pipelines, Spider Cloud is the obvious choice with its Rust-powered crawling, AI Studio, and low cost per page. If you're an ML engineer aiming to deploy models across frameworks without vendor lock-in, ONNX is essential. They're not directly comparable; pick based on your task: data acquisition vs. model interoperability.

Who should pick which

  • Solo founder building a RAG chatbot
    Pick: Spider Cloud

    Spider Cloud provides real-time web crawling and structured data extraction via a simple API, ideal for feeding context into a RAG pipeline. Its low cost ($0.03/1000 pages) and LangChain integration make it easy for a solo developer to implement.

  • ML engineer deploying a PyTorch model to production
    Pick: Onnx

    ONNX standardizes the model format, allowing the engineer to train in PyTorch and deploy on any ONNX-compatible runtime (e.g., TensorRT, ONNX Runtime), avoiding vendor lock-in. It's free and widely supported.

  • Data scientist needing to scrape 10,000 competitor pages weekly
    Pick: Spider Cloud

    Spider Cloud's high success rate (99.9%) and low per-page cost make it cost-effective for large-scale scraping. The unblocker and rotating proxies help bypass anti-bot measures, and structured output simplifies analysis.

  • Startup wanting to run ML models on edge devices
    Pick: Onnx

    ONNX allows exporting models from any framework to run on diverse hardware (CPU, GPU, NPU) via optimized runtimes. This flexibility is crucial for edge deployment without rewriting models.

Frequently Asked Questions

Onnx vs Spider Cloud: which should you choose?

Spider Cloud and ONNX serve entirely different purposes. If you need to extract web data for AI agents or RAG pipelines, Spider Cloud is the obvious choice with its Rust-powered crawling, AI Studio, and low cost per page. If you're an ML engineer aiming to deploy models across frameworks without vendor lock-in, ONNX is essential. They're not directly comparable; pick based on your task: data acquisition vs. model interoperability.

Can I use ONNX to scrape web data?

No, ONNX is a machine learning model format standard, not a web scraping tool. For scraping, use Spider Cloud.

Is Spider Cloud open-source?

Its core is open-source on GitHub, but the cloud API and AI Studio are proprietary services.

Does ONNX support training?

ONNX is an inference format; training is done in frameworks like PyTorch or TensorFlow, then exported to ONNX.

What integrations does Spider Cloud offer?

LangChain, LlamaIndex, CrewAI, FlowiseAI, AutoGen, Agno, Dify, and data connectors for S3, GCS, Google Sheets, Azure Blob, Supabase.

Can I convert Spider Cloud output to ONNX?

No, that is not a supported workflow. Spider Cloud outputs text/structured data, not ML models.

Does ONNX have a visual interface?

ONNX itself is a format; tools like Netron provide visualizations of ONNX models.

What is the latest news about Spider Cloud?

March 2026: Browser AI commands added (Act, Extract, Observe) via WebSocket.

What is the latest news about ONNX?

July 2026: Manticore Search claims 14× faster ONNX embeddings with a rewritten inference path.
