Not another Screaming Frog clone.
A lean crawler for site owners and agencies: the depth of a desktop audit tool, in an interface that tells you what to do next.
Lean by design
The checks and views you act on, without a wall of settings dialogs. Sensible defaults, and a config you can still tune when a site needs it.
Explained, not just listed
Every issue says in plain language why it matters and how to fix it, so a client or a colleague can act on a report without an SEO next to them.
Your machine, your data
No account and no upload. Each crawl is a file on your computer that you can copy, archive or open again next month to compare.
A full technical audit, without the homework.
One crawl covers status codes, titles, content, links, performance, structured data and accessibility, and puts your Google data next to every URL.
Every issue explains itself.
Each check says in plain language why it matters and how to fix it, sorted by how much it hurts: errors, warnings and notices.
Why it matters. Without a description, search engines show a random snippet from the page, which often attracts fewer clicks.
How to fix. Write a short, inviting summary of the page (about 70–155 characters).
