VoltFound vs Screaming Frog SEO Spider
VoltFound is not a replacement for Screaming Frog. It is a better crawler than ours and it is not close: it runs on your own machine and goes far deeper into a large site than we do. If you are an SEO professional, you probably already own it.
So what is VoltFound for?
Screaming Frog answers a technical question for someone who already knows what to ask. VoltFound answers a plain question for someone who does not: is my site readable to a machine, and what does an AI say about my business? You install nothing and you read sentences, not raw crawl data.
How they describe themselves
“The industry leading website crawler for Windows, macOS and Linux, trusted by thousands of SEOs and agencies worldwide for technical SEO site audits.”
