BumbleCrawl

BumbleCrawl is a desktop SEO crawler for Windows and macOS that audits your whole site like a search engine would, then explains every issue in plain language with how to fix it. Built for site owners, freelancers and agencies who want a full technical audit without a yearly licence or uploading their data anywhere.

TL;DR

BumbleCrawl is a desktop SEO spider that crawls your website, runs 200+ SEO and accessibility checks and scores its health from 0 to 100.

It ranks every issue by impact, pulls in your Search Console, GA4 and Core Web Vitals data per page, and tracks what changed between crawls so you always know what to fix next.

At-A-Glance

Overview

Most SEO crawlers hand you a spreadsheet with thousands of rows and leave you to work out what matters. BumbleCrawl crawls your site, scores its health, ranks issues by impact and tells you in plain words what is wrong and how to fix it. It runs entirely on your own computer, so there is no account, no cloud upload and no URL cap on your audits.

200+ Checks, Explained In Plain Language

BumbleCrawl runs more than 200 checks across every page, image, script, stylesheet and PDF it finds, then sorts them into errors, warnings and notices. It covers the fundamentals like status codes, titles, meta descriptions, headings, canonicals, redirects, pagination and directives, then goes further into hreflang, structured data and rich result requirements. Accessibility is checked with axe-core for contrast, labels and alt text, and security checks flag mixed content, insecure forms and missing HTTPS or security headers. Every issue comes with a plain-language explanation and a fix, so you are not googling error codes at midnight.

For a site owner, this means one scan replaces a stack of separate checkers for SEO, accessibility and security. For a freelancer, it means you can hand a client a list of real problems instead of a raw export. There is even spelling checking in English and German, and custom search and extraction with CSS selectors, XPath or regex for anything the built-in checks don’t cover. You can crawl a whole site from a start URL or paste a list of URLs to check just the ones you care about.

A Health Score That Tracks Progress

Every crawl gets a site health score from 0 to 100, modelled on Lighthouse, with ratings of good, needs work or poor. Errors carry the most weight and minor warnings barely move it, so the score reflects what actually hurts the site rather than how many notices it found. Issues are ranked by impact, so the top of the list is always the work worth doing first. The score also shows how it moved since your last crawl.

Compare mode puts two crawls side by side and shows which URLs are new, added, removed or missing, and which issues appeared or got fixed. That turns a one-off audit into ongoing issue tracking. Fix the redirect chains on Monday, recrawl on Friday, and see the proof. For anyone doing SEO for clients, it is the before and after that makes the work visible.

Sees What Search Engines And AI Crawlers See

BumbleCrawl renders JavaScript in Chromium, so pages built with React, Vue or any client-side framework are audited as they actually load, including JavaScript redirects. Rendered page screenshots and view source are there when you need to check what the crawler saw. If your site, staging environment or member area sits behind a login, BumbleCrawl signs in through your site’s own login form and crawls what is behind it.

You can also crawl as Googlebot or as AI crawlers like GPTBot, ClaudeBot and PerplexityBot, with each one’s robots.txt rules applied. That shows you exactly which pages AI search tools can and can’t reach, which most site owners have never checked. Crawl speed is adjustable too, so you can go gently on shared hosting.

Your Google Data On Every URL

Connect Google Search Console and every crawled page shows its clicks, impressions, average position and ranking keywords. Connect GA4 and you get visits per page alongside. Add a free Google API key and BumbleCrawl pulls real-user Core Web Vitals from the Chrome UX Report, so LCP, INP and CLS sit right next to the technical issues on the same URL.

This is what turns a list of problems into a priority list. A missing meta description on a page with 40,000 impressions matters a lot more than one on a page nobody visits, and now you can see that at a glance. BumbleCrawl talks to Google directly from your computer and stores keys and tokens encrypted locally.

Link Graph, Topic Clusters And Duplicate Content

The link graph groups your pages by folder and by topic, with each cluster named after its most distinctive terms, all computed on your own machine. It is a quick way to see how your site is actually structured versus how you think it is, and which sections are thin or orphaned. Sitemaps are checked against the crawl, or generated fresh, image sitemaps included.

BumbleCrawl also finds duplicate and near-duplicate pages, pages competing for the same topic and pages that drift off-topic. Content teams use this to spot cannibalisation before it costs rankings, and agencies use it to find the consolidation wins that move a client’s site quickly. An optional local language model adds meaning-based duplicate detection on top.

Built To Run Without You

Scheduled crawls run daily, weekly or monthly, compare each run against the last one and save the reports and exports to a folder. The command line runs crawls and exports from scripts or build servers without opening the window, writing a summary file you can plug into your own workflow. Every list exports to CSV or Excel, broken links export with their sources, and the PDF report is written in plain language a client can read.

The built-in MCP server connects BumbleCrawl to Claude and other assistants that support the Model Context Protocol. Your assistant can list your crawls, read issues and URLs, compare two crawls and start new ones, all on your computer. Ask “what broke since last week?” and get a straight answer instead of digging through tabs.

Stop guessing what’s wrong with your site and let the bee find it.
