Firecrawl vs ZenRows: Crawl API or Scraping Toolkit?

2. What you are actually buying

Firecrawl hosted plans (official, November 6, 2026)

Free $0 / 1,000 / 2 browsers; Hobby $19 or $16 annual display / 5,000 / 5; Standard $99 or $83 ($990/year) / 100,000 / 25; Growth $399 or $333 ($3,990/year) / 500,000 / 50; Scale $749 or $599 ($7,190/year) / 1,000,000 / 100. Scrape or crawl is 1 credit per page; search is 2 per 10 results rounded up; Interact is 2 per minute on the pricing page versus 7 per prompt-minute in the billing docs. Full calculator: Firecrawl pricing.

ZenRows official plans (November 6, 2026)

The public pricing page displays annual monthly rates first. The same page’s schema.org JSON lists the monthly-billing ranges. Both are official; both are cited here so you do not mistake $16 for the monthly invoice if you did not pick annual.

Annual billing is advertised as pay 10 months, get 12. Paid plans can buy top-ups up to 10× the period’s credits; unused top-up credits roll over once. Adaptive Stealth mode=auto starts light and bills only the setup that worked — useful, and also a reason your invoice will not match a naive “every URL = 25 credits” spreadsheet.

3. Real cost by scenario

Same named workload, two official wallets. No retries. Firecrawl uses Markdown = 1 credit and JSON = 5 unless stated. ZenRows uses the official weights: 1 / 5 / 10 / 25.

Scenario A — 8,000 simple pages a month (no JS, no premium proxy)

Firecrawl Markdown: 8,000 credits → overflows Hobby’s 5,000 → Standard $99/month (or $83 annual display). As JSON: 40,000 credits, still Standard.

ZenRows at 1 credit each: 8,000 credits fit Free’s 5,000? No — Free is 5,000, so you step to Build B1 at $19/month for 45,000 credits (or the $16 annual display if you prepay). This is the scenario where ZenRows looks dramatically cheaper, because the pages are easy and Firecrawl’s next published step after Hobby is a $99 plan with 100,000 credits you may not need.

Scenario B — 8,000 JS-rendered pages

Firecrawl does not publish a “JS rendering = 5 credits” line the way ZenRows does. A basic scrape remains 1 credit; JSON remains 5. Hosted Firecrawl is running the browser on their side as part of the product. Cost stays Standard $99 for 8,000 Markdown pages (or 40,000 credits as JSON).

ZenRows JS weight is 5 credits: 8,000 × 5 = 40,000 credits, which still fits Build B1’s 45,000 at $19/month. Headroom is thin (5,000 credits). A modest retry rate or a few protected upgrades would push you to Build B2 at $29/month (80,000 credits).

Scenario C — 4,000 protected pages (JS + premium proxies)

Firecrawl: if these are ordinary hosted scrapes, 4,000 Markdown credits fit Hobby at $19/month. As JSON: 20,000 credits → Standard at $99. Enhanced proxy is documented at the same 1 credit as a basic request; an escalated retry is not charged separately. Do not invent a Firecrawl “protected = 25” rule that the vendor does not publish.

ZenRows protected weight is 25 credits: 4,000 × 25 = 100,000 credits. That overflows Build B3 (120,000 would have worked at $39 — wait, 100,000 fits B3’s 120,000). Monthly cost: Build B3 at $39, or B2’s 80,000 is not enough so you cannot stay at $29. If half of those pages escalate only after Adaptive Stealth tries a cheaper mode, your actual bill could land lower than 100,000 credits — that is the point of mode=auto, and also why we will not promise a 100,000-credit invoice.

Scenario D — 20 hours of Browser or Interact time

Firecrawl Interact: 20 hours = 1,200 minutes. At the marketing rate of 2 credits per minute, 2,400 credits (Hobby). At the billing-docs prompt rate of 7 credits per minute, 8,400 credits (Standard). Add the one-minute minimum per session if you open many short sessions.

ZenRows Browser: official rule is bandwidth plus 5 credits per minute. The time slice alone is 1,200 × 5 = 6,000 credits, which already exceeds Free and sits on Build B1 — before whatever residential or datacenter bandwidth those minutes consumed (residential is 25,000 credits per GB). We cannot invent your bandwidth. Treat Browser as two meters, not one.

Scenario E — Prototype on the free plans

Firecrawl Free is 1,000 credits. ZenRows Free is 5,000 credits, also with no top-ups. For easy HTML checks, ZenRows Free goes further (5,000 standard pages versus 1,000 Firecrawl Markdown pages). For JSON-for-agents evaluation, Firecrawl Free holds 200 JSON pages (200 × 5 = 1,000) and ZenRows’ “Extract currently free on top of Fetch” claim would leave extraction off the credit meter — again, current-state wording, checked November 6, 2026, not a contract we can write for you.

4. Technical workflow

Documented flows only. UA ran neither API.

1. Name the output. Markdown or schema-first JSON for an LLM stack points at Firecrawl. HTML or rendered HTML you will parse, with optional stealth upgrades, points at ZenRows.
2. Name the difficulty mix. On ZenRows you should estimate what share of URLs will stay at 1 credit, what share will need JS (5), premium (10), or protected (25), and whether Browser minutes or residential GB will appear. On Firecrawl you should estimate Markdown versus JSON versus search versus Interact.
3. Firecrawl path: API key, /scrape, then /map or /crawl, then /search if discovery is in-product. Turn on JSON only with a schema. Watch Free’s HTTP 402 and crawl’s tighter rate limits.
4. ZenRows path: start with the lightest fetch that works. Adaptive Stealth mode=auto is documented to escalate and bill the setup that succeeded — better than forcing every URL through the 25-credit protected path “just in case.” If you need Browser, budget minutes and bandwidth together.
5. Read the failure rule before you write retries. Firecrawl bills a returned 403/404 document. ZenRows does not bill failures, but does bill 404/410 as usable. A retry loop has opposite cost profiles on the two sides.
6. Do not use Free as production overflow. Neither Free plan offers top-ups. ZenRows paid top-ups (up to 10×, unused top-up credits roll over once) only exist once you are on a paid family.

Concurrency is a separate axis: Firecrawl publishes concurrent browsers per plan (2 / 5 / 25 / 50 / 100). ZenRows Free publishes 5 concurrent requests; higher families raise that cap on the vendor’s plan picker. A wide crawl can force an upgrade even when the credit math still looked like the entry tier. Check the concurrency number on the plan you are about to buy, then check it again after you turn on JS or Browser, because those modes are often the ones teams try to run in parallel. A plan that looks right on credits can still throttle a morning crawl.

5. Pitfalls

• Comparing $19 to $19. Firecrawl Hobby is $19 for 5,000 credits. ZenRows Build B1 is $19 for 45,000 credits. Those 45,000 credits become 1,800 protected pages (45,000 / 25) or 9,000 JS pages (45,000 / 5). The sticker is the same; the unit is not.
• Assuming Firecrawl charges a JS multiplier it does not publish. Do not import ZenRows’ 5/10/25 weights onto Firecrawl invoices.
• Forcing every ZenRows URL through protected mode. That turns a $19 job into a mid-Build or Launch job for no reason if Adaptive Stealth would have stopped earlier.
• Trusting “Extract is free” as a forever price. Official wording today says Extract is currently free on top of Fetch. Budget a future change as a risk, not as a conspiracy.
• Mixing annual display with monthly billing. $16 Build is the annual display, not the month-to-month B1 invoice of $19.
• Using Browser minutes without counting GB. Five credits per minute is only half of the documented Browser bill.

6. Decision

Our hosted pick for LLM context remains Firecrawl. ZenRows is the tool we would evaluate in this pair when the job is fetching pages under shifting anti-bot and rendering needs, especially if failed requests must not drain the wallet. Neither vendor wins a generic “cheaper scraper” contest once you apply their own weights.

7. FAQ

Is ZenRows cheaper than Firecrawl?

Sometimes, on easy HTML (Scenario A). Not as a rule. Protected ZenRows requests cost 25 credits; Firecrawl JSON scrapes cost 5 credits; Interact and Browser are billed in minutes on different meters. Compare a named workload, not two $19 stickers.

Why does ZenRows show $16 if Build starts at $19?

The public page highlights annual monthly rates (Build from $16). Monthly billing for Build is $19–$39, with B1 at $19 for 45,000 credits. The schema.org JSON on the same page lists those monthly ranges. Annual is advertised as pay 10, get 12.

Does ZenRows charge for failed requests?

Official pricing materials say failed requests are never charged. 404 and 410 are treated as successful/usable and do count.

Does Firecrawl charge for 404 pages?

If it returns a document, yes — including a captured 404 or 403. If it returns no document, a basic scrape is generally not charged, with documented exceptions.

Do you have an affiliate link for ZenRows?

Not at the time this page was written. A hidden placeholder sits in the HTML for later; it is not visible and it does not point at a live vendor URL.
