jevcrawl vs ZenRows

jevcrawl

Three compact, typed MCP tools return verbatim passages with source URLs, cost and stop reasons, and errors arrive as codes with instructions. The project is three days old and alpha, it depends on TypeSafe's paid Jev API, which is in early access with no free tier found, and it does not block crawls of private or local addresses.

ZenRows

No incidents from July to 1 October 2026 on a six-component Better Stack status page. The Fetch API only takes the key in the query string.

jevcrawl

1. Phrase goal as one specific question and start with max_pages between 10 and 30
2. Check stats.stopped_because and stats.degraded, and read uncertain before reporting that something is missing
3. Use scrape without a goal when you need a whole page, since it makes no paid Jev call and needs no key
4. Handle {"error": code, "message": ...} results, for example auth_error means TYPESAFE_API_KEY is missing or rejected
5. Pages in stats.needs_js_urls were not read. Tell the user rather than guessing their content

ZenRows

1. Start with mode=auto and let it escalate. Force js_render or premium_proxy only when you know the site needs it
2. Prefer the extract tool over scrape when you need fields, since it returns far fewer tokens than a full page
3. Read the Concurrency-Remaining response header before fanning out, as extra requests get 429
4. Set ZENROWS_AUTO_SIGNUP=false in stdio configs so a missing key fails loudly instead of creating an account
