This page is designed to help you find out whether WebCrawler.pro is good and if it is the right choice for you.
WebCrawler Pro is a website crawler and technical SEO auditor. One scan scores every page for classic SEO, answer-engine readiness (AEO), and AI citation signals (GEO) — then you get issues, schema templates, AI drafts, and a client-ready PDF.
What a crawl checks
How it works
Paste a URL and set depth. HTML mode is fast; DOM Render executes JavaScript first (React, Next.js, Vue). Sign in to generate drafts (titles, FAQs, JSON-LD, alts, internal links, llms.txt) from the crawl — not invented facts. Use the hosted model or your own key.
Start in the browser (no install). Optional desktop for macOS, Windows, and Linux fetches pages from your computer. Every scan gets a shareable URL.
Pricing
Free to start. 50 requests/day as a guest, 100 signed in. Extra tokens: $1 / 1,000 requests, never expire.
Listed in
Deep Technical SEO
Scores titles, metas, H1s, canonicals, Open Graph, speed, duplicates, orphans, and thin content — with the exact fix.
AEO scoring
Checks featured-snippet readiness, FAQ schema, question headings, and entity clarity for answer boxes and voice assistants.
GEO scoring
Measures E-E-A-T, author, dates, factual density, and authority links so LLMs like ChatGPT and Perplexity can cite the page.
Schema inventory and templates
Lists every JSON-LD type on the site, flags missing markup, and gives copy-ready templates for Article, Product, FAQ, and more.
Action report
Groups every SEO, AEO, and GEO issue by page, with why it matters for the client and what the team should change.
Scan comparison
Diff two crawls: added or removed URLs and score changes, then print a comparison PDF to show the client what moved.
Client-ready PDFs
Send the report as-is in EN, RO, FR, ES, or DE. Add a client name and logo, or hide WebCrawler chrome.
AI drafts from the crawl
Generate titles, FAQs, JSON-LD, alts, internal links, and llms.txt from crawled data — not invented facts. Hosted model or your own key.
HTML and DOM Render modes
HTML is fast for CMS sites. DOM Render runs JavaScript first for React, Next.js, Vue, and Angular.
Indexation view
Puts noindex, orphans, robots, canonicals, redirects, and sitemap gaps in one “will Google see this?” check.
Accessibility pass
Runs on the same HTML as markup: lang, skip links, labels, fake buttons, and rough contrast.
Save and share scans
Every scan gets a unique URL. Sign in with Google for history across devices. Export CSV or JSON.
Browser or desktop
Start in the browser with no install. Optional Mac, Windows, and Linux app fetches pages on your machine (no CORS, no hosted quota).
Pay-as-you-crawl tokens
50 free requests/day as a guest, 100 signed in. Extra capacity is $1 per 1,000 requests. Tokens never expire.
Most crawlers still score classic SEO only. WebCrawler Pro scores three engines in one scan: technical SEO, AEO (answer-engine / snippet readiness), and GEO (signals that help ChatGPT, Perplexity, Gemini, and Claude cite a page). It runs in the browser with no install. Desktop is optional and fetches from your machine, so those crawls skip CORS and do not use the hosted quota. Findings come with schema templates, crawl-grounded AI drafts (hosted or your own key), and a client-ready PDF you can brand. A built-in Pedia explains each check.
Choose it when you need AEO and GEO in the same report as titles, canonicals, and indexation — without a desktop-only suite or a $200/month SEO platform. You can start as a guest (50 requests/day), sign in for 100/day and saved history, then buy tokens at $1 per 1,000 that never expire. HTML mode is fast; DOM Render handles React, Next.js, and Vue. Agencies get multilingual PDFs (EN, RO, FR, ES, DE) with client name, logo, and optional white-label. Desktop crawls and BYOK AI do not burn hosted tokens.
Freelance SEOs, small agencies, and in-house marketers who already ship technical audits and now also need pages ready for featured snippets and AI citations. Secondary: site owners and content teams who want a serious crawl in the browser, a shareable report, and a PDF they can send — without buying an enterprise crawler.
Vanilla JavaScript (ES modules) and Webpack on the front end; PHP with cURL as the CORS proxy; SQLite for users, sessions, and rate limits; JSON files for saved scans. Auth is Google OAuth. Billing is Stripe and PayPal. The optional Mac / Windows / Linux app is Electron and crawls locally. AI drafts use a hosted model or a bring-your-own OpenAI, Gemini, or Anthropic key stored only on the user’s device. Webcrawler.pro is hosted on a i3 laptop with 4gb of ram in my shed:D
I built WebCrawler Pro as a frontend developer who worked with several SEO agencies. The same pattern kept showing up: they asked for simple technical fixes (titles, canonicals, schema, missing alts)that should already have been there if a developer had run an SEO check before shipping.
So I made a crawler that tells both sides what to do. Programmers get exact fixes. Agencies get a report they can send: why each issue matters for the client, and what the team should change. Compare two scans and the PDF shows what actually moved - added or removed URLs, score drops and gains -so you can justify the work (and the invoice) with before/after, not a slide deck.
It makes checking a website’s health simple and less stressful. It runs directly in your browser, and it caches broken links and page issues in minutes.
I like a lot that it checks how easily modern AI tools can read your site, which some of the tools I tested miss. The best thing is that you only pay for what you actually use instead of being locked into an expensive monthly subscription. I highly recommend it!
The resulting report was highly detailed and very useful for improving the application's parameters. It was particularly helpful with GEO scoring, a feature I don't find in the standard tools I was using.
WebCrawler.pro is a sharp, forward-thinking utility for SEOs and site owners who need to know not just how Google views their pages, but whether AI answer engines can parse, trust, and cite them. It punches well above its weight class for quick, modern technical checks.
We use WebCrawler Pro on client sites before we call the work done. One scan scores technical SEO, AEO, and GEO, then tells the developer the exact fix instead of a vague “improve your titles” note.
What I keep using: the action report (why it matters for the client, what to change) and the compare view between two scans. That before/after is what we send when we have to show what actually moved.
It runs in the browser, so the team can open it without installing anything. Daily free cap if you stay on the hosted crawl — for a normal agency audit it’s enough; for a huge site you’d want tokens or the desktop app.
For launch checks and client reporting, this is the one I’d recommend.
