If you’ve built scrapers recently, you already know the state of the market: - Traditional proxy providers (Bright Data, Oxylabs, Smartproxy, Proxybase) give you raw IPs or massive unparsed HTML blobs, leaving you to deal with DOM bloat, token waste, and brittle parsing pipelines. - Modern tools like Firecrawl or Jina made clean Markdown extraction easy for hobby setups, but they often struggle when you throw heavy SPAs, high-concurrency jobs, or hardened anti-bot walls (Cloudflare Under-Attack / Turnstile, Kasada, DataDome) at them. - Rolling your own Playwright / Puppeteer cluster works until target sites deploy new JA4/TLS fingerprints, and your data team ends up spending 30% of their sprints fixing broken crawlers instead of shipping product. We're tackling this by combining a low-latency Rust fast-fetch engine (JA4/TLS and HTTP/2 frame emulation) with an isolated stealth browser fleet, zero-code schema validation (JSON Schema/Pydantic), and...
