Stop guessing what's broken on your site. Crawl it.
Seodisias is the desktop SEO crawler we build in-house. It crawls your site on your own computer, with no page limit, and lists what it finds by priority: titles and structured data, page speed, whether AI crawlers can get in, and more. The crawler is free and will stay free.
01What it does
See the technical state of a site in one crawl
Search engines and AI crawlers don't tell you where they get stuck. A broken link, a wrong canonical or a robots.txt line that keeps bots out can go unnoticed for months. Seodisias walks the whole site the way a bot would and puts those problems in front of you, page by page. We built it for SEO specialists, agencies and in-house teams who look after their own site.
Runs on your machine
Crawl data and reports stay on your device. Your site's data isn't sent to anyone's server.
No page limit
A corporate site with a few hundred pages and a catalogue with tens of thousands get crawled the same way. The free version has no crawl cap.
Sorted by priority
Every issue is marked high, medium or low priority, so the things to fix first sit at the top of the list.
0231 modules
What a crawl checks
Each check is its own module. New checks arrive through regular app updates.
Crawling
How bots move through the site
robots.txt, noindex and nofollow directives, XML sitemaps, canonical tags, response codes, redirects, URL structure, and how deep important pages sit from the homepage.
International
Hreflang and structured data
Missing return links between language versions, wrong language or region codes, Schema.org errors, and Google's rich result requirements.
Technical health
Speed, mobile and server settings
Page load times, compression, cache headers, mobile usability and favicons. The crawl summary also shows average response time and the slowest pages.
Security
SSL and security headers
SSL certificate details, HTTPS and mixed content, HTTP security headers, and domain age.
AI
AI readiness and E-E-A-T
Whether AI crawlers can reach the site, llms.txt, author and organization markup, contact details, physical address and privacy policy. It all rolls up into a single readiness score.
03Reports and install
What you walk away with
PDF and Markdown reports
Export results as a PDF. The Markdown export is there so you can hand the report to an AI assistant and work through it.
macOS, Windows, Linux
The macOS build is signed and notarized by Apple. On a Mac you can also install it with Homebrew: brew install --cask aligundogdu/seodisias/seodisias
Updates from inside the app
New versions ship regularly. You update from within the app, and every release is documented in the changelog.
04Roadmap
What we're still building
Seodisias is live and grows with every release. The items below are in progress or on the list; they're plans, not dated promises.
Cloud reports and share links
Share a report through a link, without the other side creating an account. Designed with agencies presenting to clients in mind.
Team features
Team accounts, invitations and roles, so you can work from the same crawl results as your colleagues.
Paid plans
Two paid plans are on the roadmap: one for team collaboration, one for AI and GEO analysis. The crawler stays free.
05At Sparkzone
Our measuring tool for visibility work
When we start working with a client on visibility, the first thing we do is crawl their site with Seodisias. That list becomes the basis of the first month's plan. We check our own changes with the same tool, before they go live and after.
Same tool, same yardstick
We run the same checks every month, so the difference between two months reflects the work we actually did.
Lessons from client sites
Problems we run into on client sites shape which checks we add to the app next.
Visibility service
On top of measurement we add content, technical fixes and monthly tracking.
