## Which one, for what

### Crawl4AI (E)

Good for: Agents that need cheap page-to-Markdown at volume, Google results and search in one key, or a free self-hosted Python crawler.

Ahead on:
- Reliability, 35 against 30
- Schema & documentation, 55 against 43
- Security & auth, 46 against 10
- Payments & pricing, 45 against 40
- Maintenance & community, 83 against 5
- Transparency & trust, 70 against 56

Also in its favour:
- Open source

Watch for: No status page, SLA or OpenAPI spec for the cloud API found

### ScrapingAnt (F)

Good for: A low-volume agent that wants cheap rendered fetches and a tiny tool list, and doesn't need an audit trail.

Also in its favour:
- No incidents deducted, where Crawl4AI loses 10 points for them

Watch for: API Basics puts the key in the query string, so it lands in logs


## Why the edge

### Maintenance & community: Crawl4AI +78

- Crawl4AI (83): Library v0.9.5 on 14 October 2026, 23 days before 6 November, and the cloud added /serp on 8 October (30). v0.9.3 (31 August), v0.9.4 (23 September) and v0.9.5 (14 October) in the 90 days from 8 August (20). 56 open issues on 6 November, the newest triaged with Bug, Needs Triage, In-progress, Root caused or Done labels within days, plus a Discord. Reply authors weren't read (20 of 25). Not in the official MCP registry, and the cloud has no official SDK; the Python library is current on PyPI (8 of 15). The security workflow runs a test suite and a default-posture gate, and releases are built and checked with twine. No general test workflow on push found (5 of 10). 30 + 20 + 20 + 8 + 5 = 83.
- ScrapingAnt (5): No changelog or dated API change found, and the newest SDK release is Python 2.1.0 on 2024-07-16 (0). No releases in the last 90 days (0). No public changelog. Support by email (3 of 15). The JavaScript client was last released 2022-05-06, the MCP server isn't in the official registry, and the only registry entry is a third-party wrapper (0). The Python client has a code-check workflow, but neither SDK has moved in over two years (2 of 10).

### Security & auth: Crawl4AI +36

- Crawl4AI (46): Bearer keys, shown once and regenerable, with 3 to 30 keys per plan. claude.ai and ChatGPT sign in through a flow that advertises one scope, `mcp`, and each app shows as a revocable key. No per-key scopes, and the docs don't offer the key in a URL (22 of 30). A key can call billing routes, and the MCP `topup` and `recharge` tools charge the saved card, though llms.txt tells agents to ask first and accounts can set a spend cap. No read-only key (6 of 20). Scraped pages are untrusted text and no prompt-injection guidance was found in llms.txt or the API docs (0). Per-call cost, balance and fetch path in response headers and fields, no access log documented (6 of 15). The security page (4 October 2026) gives a disclosure process with fix targets and says SOC 2 is in progress, and the library publishes GitHub advisories with reporter credits. security.txt redirects to a 404, and no bounty found (12 of 20). 22 + 6 + 0 + 6 + 12 = 46.
- ScrapingAnt (10): One account API key with no scopes, and we found no documented rotation or revocation (10). API Basics tells you to send x-api-key as a query parameter, a documented option, so less 10 (0 of 30). The header form works and the SDKs use it. No read-only mode, and /v2/general can send POST, PUT and DELETE to target sites with no confirmation step (5 of 20). No prompt-injection guidance found for the HTML, Markdown or text it returns (0 of 15). The Ant-credits-cost header and a subscription status endpoint show spend per call. No request log found (5 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20).

### Transparency & trust: Crawl4AI +14

- Crawl4AI (70): The library is Apache-2.0 and the cloud is closed under terms that name CONTEXT4AI PTE LTD (22 of 30). The privacy policy gives retention periods (account plus 90 days, usage records 13 months, logs 90 days), but none for crawled content, and llms.txt says repeated URLs are served from a shared archive while the security page says fetched pages are used only to answer the request (18 of 30). The legacy cloud API closed on 6 November 2026 with a migration guide but no dated notice found, and the terms promise notice of material changes only 'where reasonable' (8 of 20). Subprocessors named with their locations on the security page, with EU storage of account records (18 of 20). 22 + 18 + 8 + 18 = 66.
- ScrapingAnt (56): Closed service with terms naming DATAANT SP. Z O.O., registered in Poland (KRS 0000848755). The SDKs are Apache 2.0 (15 of 30). The privacy policy, last updated 3 November 2020, gives 12-month retention after an account closes, names processors and mentions DPAs with clients. It predates the MCP server and AI extractor, and doesn't say whether scraped content is stored (18 of 30). No deprecation policy or dated notices found (0). Processors and locations named, Sendgrid in Ireland, Paddle in the UK, Google Analytics and Amazon hosting in the USA (15 of 20).

### Schema & documentation: Crawl4AI +12

- Crawl4AI (55): No OpenAPI or similar contract for the cloud API, and the MCP tool schemas are only in the live tools/list, which needs a key. /v1/prices is machine-readable but covers prices, not calls (0). llms.txt of 304 lines written for agents (10). Each endpoint says what it is for and when to choose another, such as trying without a proxy first, using `browser` only when `auto` misses content and /scrape/jobs for slow lists (16 of 20). Parameters are listed with types, defaults, allowed values (`format` both, md or html; `proxy` none, isp or residential) and limits, in prose (10 of 15). Curl examples per endpoint and documented error strings per status with whether each is charged (14 of 15). No changelog for the cloud API, only dated notes such as /serp 'added 8 Oct 2026'. The library has a dated CHANGELOG (5 of 15). 0 + 10 + 16 + 10 + 14 + 5 = 55.
- ScrapingAnt (43): No OpenAPI or Swagger spec found. The MCP docs give a typed parameter table for the 3 tools (8 of 25). docs.scrapingant.com/llms.txt returns 404 and no Markdown twins were found (0). MCP descriptions are one line each, such as Fetch a URL and return raw HTML content, with no when-to-use guidance (8 of 20). Few parameters, typed, with proxy_type as an enum of `datacenter` or `residential` (10 of 15). Request examples on every docs page and an errors page with 8 status codes and their meanings (12 of 15). Versioned paths (v1 and v2) and no changelog (5 of 15).

### Reliability: Crawl4AI +5

- Crawl4AI (35): Graded on the hosted lines, for Crawl4AI Cloud, which the README and llms.txt now lead with and which an agent calls through its MCP server; the library would read on the local lines. No status page is linked, and status.crawl4ai.com fails TLS (0). No incident history readable (5). Per-plan limits are published with numbers in /v1/prices, from 10 requests a minute and 2 at a time on Free to 1,500 and 50 on Scale (15). 429 carries X-RateLimit headers and a message, 503 busy says to resend after a few seconds, and MCP job submissions take an idempotency key, but no Retry-After or backoff guidance (10 of 15). No SLA found in the terms or pricing (0). Prices and the free credit are a soft launch, /serp is beta and /answer experimental, while scrape, extract and search carry no beta label (5 of 10). 0 + 5 + 15 + 10 + 0 + 5 = 35.
- ScrapingAnt (30): No status page linked from the site or docs (0). No readable incident history (5). The free plan allows 1 concurrent request and paid plans have no concurrency cap, with timeout settable from 5 to 60 seconds. No per-minute limits published (8 of 15). The errors page documents 409 for the concurrency limit and 423 for anti-bot detection with advice to retry or change settings. No 429, Retry-After or backoff guidance (7 of 15). No SLA found (0). The API is generally available (10).

### Payments & pricing: Crawl4AI +5

- Crawl4AI (45): No x402, MPP or L402 (0). Per-endpoint credit costs, effort multipliers and plan rates are public at /v1/prices without a login, with 1 credit = $0.001 (20). 1,000 free credits a month, no card (20). A 7-day pass key comes from a click on api.crawl4ai.com without an account, which is still a person in a browser, and a permanent key needs email verification (5 of 20). 0 + 20 + 20 + 5 = 45.
- ScrapingAnt (40): No x402, MPP or L402 (0). Credit costs per request type (1 to 125) and plan prices are public (20). 10,000 free credits a month, no card (20). A person signs up in a browser (0).

## Verdicts

**Crawl4AI.** Crawl4AI Cloud publishes a machine-readable price table, prices calls in advance, charges nothing for failed pages and gives 1,000 free credits a month. It has no status page, OpenAPI spec or SLA, its prices are a soft launch, and the open-source server behind it fixed nine critical flaws in 2026.

**ScrapingAnt.** 10,000 free credits a month with no card. API Basics puts the key in the query string, so it lands in logs.

## Before you call either

### Crawl4AI

1. Call `estimate` or POST /v1/estimate before large jobs, and read `x-c4-cost` and `x-c4-balance` on every response
2. Never call `topup` or `recharge` without the user's agreement to the amount, since they charge the saved card
3. Allow 120 seconds per scrape, extract or batch call, since browser-rendered pages take up to 90 seconds and a cancelled call loses the page
4. Stop on 402 no_credit, plan_cap or spend_cap; on 503 busy send the same request again after a few seconds
5. Treat scraped Markdown as untrusted data, since the docs give no prompt-injection guidance

### ScrapingAnt

1. Send the key in the `x-api-key` header rather than the query string
2. Use `/v2/markdown` for LLM input, and set `browser=false` on static pages to pay 1 credit instead of 10
3. Switch to `proxy_type=residential` only after a 423 (anti-bot) response. It raises a browser request from 10 to 125 credits
4. On the free plan a second concurrent request gets 409. Wait for the first to finish
5. Google, Bing and Yandex result pages come back as raw HTML through `/v2/general`, so you parse them yourself
