# Spider

Spider is a high-performance web crawling and scraping platform engineered for the throughput and output quality that AI applications demand. It can crawl an entire website in seconds and return clean, structured data — Markdown, HTML, screenshots, or JSON — tuned for feeding directly into LLMs, RAG pipelines, and embedding workflows without extensive post-processing. The API handles JavaScript rendering, anti-bot bypass, proxy rotation, and dynamic content automatically, so developers can point it at any URL and get reliable, structured results without managing headless browser infrastructure. Spider supports streaming, webhooks, custom user agents, content filtering, and fine-grained depth and budget controls, making it practical to run large-scale crawls cost-effectively. It targets AI engineers and developers building training datasets, knowledge bases, retrieval-augmented generation systems, web agents, and competitive intelligence pipelines who need fast, reliable web data at scale.
