Comparison
DIY SEO Hub vs Sitebulb
Sitebulb is a paid crawler whose real product is the explanation: it tells you why something matters and what to do about it, in an order. That is a harder thing to build than the crawling.
This is free, browser-based, and narrower. Details on both sides change; check theirs before deciding.
The short version
| DIY SEO Hub | Sitebulb | |
|---|---|---|
| Price | Free, no account, no paid crawling tier | Paid subscription, with a trial; desktop and cloud options |
| Where it runs | Our servers, from a browser tab | Your machine, or their cloud |
| Pages per crawl | 5,000 | Far more, by plan |
| JavaScript rendering | No | Yes |
| Explaining the findings | A written fix plan, ordered, from your own results | Hints with reasoning and priority, its best feature |
| Visual reports | An internal link graph and a score histogram | Crawl maps and a lot more charting |
| Security review | Yes, passive, on every finished scan | Some security hints as part of the audit |
| Raw data | The whole crawl as SQLite, page bodies included | Exports, and its own project files |
| Public shareable report | Yes, a page per domain | Exported reports you send |
Where Sitebulb is better
It teaches while it audits. Every hint carries an explanation of the underlying issue. For somebody learning technical SEO that is worth more than the crawl.
Prioritisation. Sorting findings by likely impact is a judgement call they have done thousands of times and encoded. Our fix plan does this too, written from your scan, but theirs is more considered.
Scale and rendering. Bigger crawls, JavaScript, more checks, more integrations.
Where this is better
Nothing to buy or install. The comparison only starts to favour us when the question is “is something broken on this one site, today”, and you do not want a trial, an install and an account first.
The data is yours in a standard format. A Sitebulb project opens in Sitebulb. Our crawl is a SQLite file that opens in anything, and still will in ten years.
Public reports. Every scan gets a page anyone can read, which is useful for handing a developer the evidence without exporting a PDF.
Questions people ask
- Is there a free alternative to Sitebulb?
- For finding technical faults on one site, yes: a scan here is free, needs no account, and covers 5,000 pages. What you give up is Sitebulb's explanations, its prioritisation and its visual reports, which are the reasons people pay for it.
- What is Sitebulb best at?
- Turning a crawl into a report somebody else can read. Its hints explain why each issue matters and roughly what it is worth fixing, which is exactly the part most crawlers leave to you.
- Do you have anything like its crawl maps?
- A simpler version. Every report here draws the internal link graph, which shows clusters and stranded pages, and the underlying node and edge data is in the downloadable database if you want to draw your own.
