# Free SEO Crawlers That Actually Work (No BS Edition)

Indexation & Crawl Simulators Free crawlers that mimic how Googlebot sees your site—revealing blocked pages, weird redirects, or orphaned content.

**Simple-Pimple** : You want free shit that crawls your website like Google does? Here are 4 tools that won’t make your brain hurt.

* * *

## The “Just Works” Option: SEOnaut

**Link** : [https://github.com/StJudeWasHere/seonaut](https://github.com/StJudeWasHere/seonaut)

**What it does** : Scans your entire website and tells you what’s fucked up. Broken links, missing titles, duplicate content - the works.

**Why it’s good** :

- One-click Docker setup (even your grandma could do it)
- Pretty charts that make you look smart in meetings
- Actually tells you what’s wrong instead of cryptic nerd speak

**How to use** : Download, run `docker-compose up`, visit `localhost:9000`. Done. No PhD required.

## The Python Nerd Special: Site-One Crawler

**Link** : [https://github.com/janreges/siteone-crawler](https://github.com/janreges/siteone-crawler)

**What it does** : Command-line tool that crawls sites and spits out detailed reports. Think of it as a really nosy neighbor who notices everything wrong with your house.

**Why it’s good** :

- Works on Windows, Mac, Linux (pick your poison)
- Exports to CSV so you can torture yourself with spreadsheets later
- Checks SEO, performance, and accessibility all at once

**Reality check** : You’ll need to learn some command-line shit, but it’s not rocket science.

## The Speed Demon: Hakrawler

**Link** : [https://github.com/hakluke/hakrawler](https://github.com/hakluke/hakrawler)

**What it does** : Fast as hell link finder. Discovers all the URLs on your site, including the sneaky JavaScript ones hiding in corners.

**Why it’s good** :

- Stupid fast (written in Go, which is nerd for “really fucking quick”)

- Perfect for finding orphaned pages that Google can’t see

**Best for** : When you just want a quick “what pages exist on this site?” answer.

## The All-In-One Dashboard: SEO Audits Toolkit

**Link** : [https://github.com/StanGirard/seo-audits-toolkit](https://github.com/StanGirard/seo-audits-toolkit)

**What it does** : Web interface that bundles multiple SEO tools. Like having a Swiss Army knife instead of carrying 20 different tools.

**Why it’s good** :

- Pretty web interface (no ugly command lines)
- Lighthouse scores, SERP checks, sitemap analysis
- Docker setup so you don’t have to deal with dependency hell

**Warning** : Hasn’t been updated since 2020, so it might be a bit crusty. But hey, free is free.

* * *

## Quick Start Guide (For the Impatient)

**Step 1** : Pick SEOnaut if you want the easiest experience  
**Step 2** : Install Docker (Google “install Docker” + your operating system)  
**Step 3** : Download the tool, run the Docker command  
**Step 4** : Point it at your website  
**Step 5** : Get coffee while it does its thing  
**Step 6** : Fix the shit it finds

**Pro tip** : Start with one tool. Don’t try to use all four at once unless you enjoy digital masochism.

* * *

## The Bottom Line

These tools do the same job as expensive crawlers like Screaming Frog Pro or Sitebulb, except they’re free and open-source. Will they have every bell and whistle? Nah. Will they catch 90% of your SEO problems? Absolutely.

Stop overthinking it. Pick one, crawl your site, fix the obvious problems. Your rankings will thank you later.
