Solid for our team
We rolled this out across the team last quarter and sDKs and integrations with major AI frameworks. Schema and prompt-based data extraction fits neatly into how we already work, and scrape, crawl, map, and extract endpoints removed a step we used to do by hand. Schema-based extraction needs tuning for complex pages, which is the main caveat, but it has held up under daily use.
Does the job
Pretty happy overall. Cloud API plus self-hosted deployment option just works and handles JS rendering and dynamic pages. but no dealbreakers — I'd recommend it to a friend without hesitating.
Does the job
Pretty happy overall. Markdown, HTML, and structured JSON output just works and outputs clean markdown and JSON ready for LLMs. Schema-based extraction needs tuning for complex pages can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.
Use it every day
Honestly didn't expect to like it this much. Cloud API plus self-hosted deployment option is exactly what I needed, and sDKs and integrations with major AI frameworks. I do wish heavy crawls may still hit site rate limits, but I reach for it almost every day now and it just clicks.
Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on python and Node SDKs with LangChain support, and sDKs and integrations with major AI frameworks caught me off guard. Heavy crawls may still hit site rate limits is why this isn't a perfect score, still, I'd recommend giving it a real trial.
Compared a few options
Evaluated this against two competitors. Where it wins: markdown, HTML, and structured JSON output and handles JS rendering and dynamic pages. On balance the feature set — especially scrape, crawl, map, and extract endpoints — justifies the 5 stars for our use case.
