Who should pick which
- Enterprise with proprietary data needing a custom AI modelPick: Feyn
Feyn offers full model weight ownership and continuous learning from your production data, ideal for specialized tasks like document analysis or unique classification problems.
- A team building an AI agent that needs to browse the web in real timePick: Spider Cloud
Spider Cloud provides fast, cheap web crawling and scraping with Browser AI commands, LangChain integration, and a 99.9% success rate—perfect for RAG pipelines.
- A startup with limited budget and some data to train a modelPick: Spider Cloud
Spider Cloud is self-serve and pay-as-you-go (freemium). Feyn's contact-based pricing is likely too expensive; Spider Cloud's $0.03/1k pages is far more affordable.
- A researcher who needs to extract main content from millions of HTML pagesPick: Spider Cloud
Both could work, but Spider Cloud's Rust engine and Pulpie-like tools (from Feyn) are not directly comparable. Spider Cloud's AI extraction fallback and scraper catalog offer immediate value.
- A company requiring full ownership of a model trained on confidential dataPick: Feyn
Feyn explicitly offers model weight ownership and a collaborative process, ensuring sensitive data stays private. Spider Cloud does not offer custom model training.
