## Key features

- **Issues ranked by severity:** Each crawl produces a report that groups problems as critical, high or low, from broken links and redirect loops to duplicate titles and descriptions.
- **On-page and content checks:** Audits titles, descriptions, heading order, hreflang tags, image alt text and file size, thin or duplicated content, canonicals and HTTP pages.
- **Crawl settings:** The crawler can ignore robots.txt, follow nofollow links, include sitemaps and subdomains, check external links and log in to staging sites with HTTP Basic Auth.
- **Site structure and dashboard:** Spots orphan and dead-end pages, checks response time and timeouts, and charts site health over time on a visual dashboard.
- **WACZ archives:** Saves a crawled site as a WACZ web archive, keeping pages and assets for offline review or record-keeping.
- **Self-hosting with Docker:** Written in Go with a MySQL database; the project publishes a Docker image and a Docker Compose file, and the interface can be translated.

## Good for

- Small sites that fit within 500 URLs on the free hosted plan
- Teams that want to run their SEO crawler on their own server
- Budget technical audits of up to five sites

## Worth knowing

- The hosted Growth plan stops at 5 projects and 10,000 URLs each; larger needs are handled by emailing the developer.
- Self-hosting needs Docker or Go plus a MySQL database, and the project recommends adding HTTPS through a reverse proxy.
- Support is by email for the hosted service and through GitHub Issues for self-hosted copies; there is no forum.
- Of the hosted plans, only the paid Growth plan lists recurring audits; Lite crawls run on demand.

## ToolGPA grades

**GPA: 2.4 out of 4**, graded Oct 23, 2026. SEOnaut crawls a site and sorts what it finds, from broken links and redirect loops to hreflang and canonical errors, into critical, high and low, with history on a dashboard. The hosted free plan stops at 1 project of 500 URLs, Growth at $9 a month stops at 5 projects of 10,000, and running it yourself means Docker or Go plus MySQL.

- **Value for money: B.** Growth is $9 a month for 5 projects of up to 10,000 URLs each, inside this category's cheaper quarter of $13, and a yearly plan gives one month free. The free self-hosted edition needs a server of your own.
- **Free plan and trial: B.** The hosted Lite plan is free with no card: 1 project of up to 500 URLs, crawled when you ask. A small site can live on that, though recurring audits are Growth only.
- **Features: C.** Issues ranked by severity, title, heading, hreflang, image, canonical and thin-content checks, orphan pages, history charts and WACZ archives. The gaps: the listing records no JavaScript rendering, Search Console data or API, and hosted plans stop at 10,000 URLs a project.
- **Ease of use: C.** No rating on record. The hosted version means an account and a project before the first crawl; self-hosting needs Docker or Go, MySQL and a reverse proxy for HTTPS.
- **Platforms and integrations: C.** Web only, with a Docker image for running it yourself. No API, integrations, desktop or phone app on record.

## Keep it, or make your own?

**Your call.** SEOnaut sits between: not beyond making, and not a weekend's work either. What you would give up is listed below. Whether that is worth the price is your call. It costs $108 a year. SEOnaut is open source, so there is a third way: take its code and run it yourself.

- You could make: It runs in a browser, which is where something home-made would run too.
- You could not: A crawler that checks every page of a site.
