We build the data infrastructure for AI.
Spider started as an open-source Rust web crawler and became a question: how do you know web data is good? We run it as a quality lab and answer in public. Open source core, open benchmarks, and a bill that reads $0 when a page fails.

spider, open source
A low-latency Rust crawler. Concurrent by default, designed to crawl thousands of pages a second on a single host. MIT-licensed at github.com/spider-rs/spider.
- 2024
Spider
The same crawler, hosted. Stealth, proxies, anti-bot, and auto-scaling rolled in. JavaScript rendering included; pay only for bandwidth and compute used.

AI extraction
Send a prompt and a URL, get structured JSON. Selectors and parsers are still there if you want them, but most teams stop reaching for them.

The quality lab
Silk, our extraction model. StealthBench V1, published with methodology. The work shifted from moving pages fast to proving the data is right: fidelity, completeness, freshness, provenance.
