WebCrawler Pro

Overview

WebCrawler Pro is a website crawler for site owners and agencies evaluating technical SEO alongside answer-engine and generative-engine signals. It is best suited to people who want configurable crawling, exportable reports, and optional AI drafts in one tool.

Its appeal is the breadth of its checks and deployment options; crawl barriers and unsigned desktop installers are meaningful trade-offs.

Key features

Technical SEO, AEO, and GEO checks

The crawler checks page titles, meta descriptions, H1s, canonicals, Open Graph tags, response times, and page size, as well as duplicate content, orphan pages, and thin content. AEO checks cover FAQ schema and question-based headings. GEO checks consider author attribution, date freshness, factual density, authority links, and signals of original research. This makes WebCrawler Pro relevant to teams reviewing content visibility beyond conventional technical SEO, though the results still need human judgment before changes are made.

Crawl modes and reports

HTML mode fetches raw server responses, while DOM Render executes JavaScript before extracting content. The latter is useful where page content depends on client-side rendering. Reports include crawl-depth charts, score distributions, response-time histograms, page breakdowns, and site summaries, with PDF, CSV, and JSON exports.

Agencies can produce client-ready PDFs with a client name and logo or hide WebCrawler branding. Findings can be presented in English, Romanian, French, Spanish, or German, a practical advantage for serving clients across language markets.

AI drafts, integrations, and privacy

Signed-in users can generate draft titles, FAQs, JSON-LD, alt text, internal links, and llms.txt using the hosted model or their own API key. The FAQ names Google sign-in and support for user-provided OpenAI, Gemini, and Anthropic keys; it says a user's own key stays on their device. These drafts can speed up follow-up work, but should be reviewed before publication.

Signed-in scans are private to the account. Anonymous saved scans are accessible by unique URL, so that mode warrants care when sharing or saving sensitive site information. The maker says scan data is not shared, sold, or analysed.

Crawl limitations and deployment

Pages behind login walls, pages disallowed by robots.txt, and sites using advanced bot detection may not be fully crawlable. That makes the tool a weaker fit when complete coverage of protected or heavily defended sites is essential.

Web access, Linux, macOS, Windows, and self-hosting are supported. The PHP and vanilla JavaScript project can be self-hosted with PHP 7.4 or later and the pdo, pdo_sqlite, and curl extensions. Desktop installers are not Apple-notarized or Microsoft-signed; the maker advises checking their SHA-256 sums. That extra caution may make self-hosting or browser access preferable for security-conscious environments. The maker aims to reply to support requests within 1–2 business days, with bug reports and crawl issues usually answered faster.

Pricing

Free access

The free daily allowance is 50 requests per day as a guest or 100 requests per day when signed in, with no credit card required. Guest access suits occasional checks; signing in doubles the daily allowance and is the better choice for regular use.

Paid tokens

Paid tokens cost 1.00 USD per month for 1,000 requests. Users choose a monthly token cap, and unused tokens do not expire. This is a modest step up for users who outgrow the daily allowance, though request volume remains the central constraint.

Prepaid crawl tokens are priced at 11000.00 USD per once. Users choose a monthly cap in the app, and tokens never expire. They are used after the daily free allowance; hosted AI suggestions and PHP proxy crawls draw from the same request pool. That shared pool matters if a user intends to combine crawling with AI suggestions or proxy requests.

Platforms

WebCrawler Pro supports web use, Linux, macOS, Windows, and self-hosting. Browser access avoids the unsigned installer issue, while self-hosting suits users able to meet the PHP and extension requirements.

Who it's for

WebCrawler Pro fits site owners who want technical, AEO, and GEO checks together, and agencies that need multilingual, client-branded PDF reports. Its free daily allowance makes it approachable for lighter work, while token options provide a route beyond those daily caps. It is less appropriate when login-protected or bot-protected pages must be crawled reliably, or when an organization requires signed desktop installers.

Pros and cons

• Pros: Combines technical SEO, AEO, and GEO checks, including structured data auditing, so teams can review several classes of page signals in one crawl.
• Pros: PDF, CSV, and JSON exports, plus customizable multilingual client PDFs, support both analysis and agency delivery.
• Pros: HTML and JavaScript-rendered crawl modes, web access, and self-hosting give users multiple ways to fit the tool to their sites and setup.
• Cons: Login walls, robots.txt exclusions, and advanced bot detection can limit coverage, which is a concern for sites with restricted or guarded pages.
• Cons: macOS, Windows, and Linux installers are unsigned or not notarized, requiring extra caution before installation.
• Cons: AI suggestions and PHP proxy crawls use the same request pool as paid tokens, so those tasks compete for the same allowance.

Verdict

WebCrawler Pro is a strong fit for site owners and agencies who want technical SEO, AEO, and GEO reviews paired with flexible exports and client-ready reports. Its free daily allowance and token options provide room for different workloads. Look elsewhere if your work depends on reliably crawling login-protected or bot-protected pages, or if unsigned desktop installers are unacceptable.
