What is Screaming Frog?
Screaming Frog is a powerful website crawler — known as the SEO Spider — that's an essential tool for technical SEO audits, letting professionals crawl a website like a search engine does and analyze it for issues at scale. Technical SEO requires examining a site's pages, links, redirects, metadata, and structure to find problems that hurt search performance, which is impossible to do by hand on any sizable site. Screaming Frog automates this by crawling an entire website and surfacing the technical details and issues SEOs need to find and fix, making it a staple in the toolkit of serious SEO practitioners.
The tool crawls a website and collects a wealth of data on every page: status codes, broken links, redirects, page titles and meta descriptions, headings, duplicate content, images, structured data, and much more. This lets SEOs quickly identify technical problems — broken links, missing or duplicate metadata, redirect chains, crawl errors, and other issues that affect rankings — across sites of any size. It integrates with analytics and other data sources, supports detailed configuration for how it crawls, and exports data for analysis. For technical SEO audits, few tools match its depth and precision, which is why it's relied on by SEO agencies and in-house teams alike.
Screaming Frog is used by SEO professionals, agencies, and technical marketers who need to audit websites and diagnose technical SEO issues thoroughly. The value is comprehensive technical insight: it reveals exactly what's happening across a site's pages and links, surfacing the technical problems that hurt search performance so they can be fixed. For anyone responsible for a website's SEO health, the ability to crawl and analyze a site in depth is essential, and Screaming Frog is the long-standing industry standard for the job. For technical SEO audits and ongoing site analysis, it remains an indispensable, widely trusted tool.
What is Vectr4?
Vectr4 is a self-hosted product analytics platform built for SaaS founders, indie hackers, developers, and small product teams that want to understand how users interact with their products while keeping full control of their analytics data.
With Vectr4, you can track product events, users, sessions, funnels, conversions, and customer journeys from one central dashboard. It is designed to help you see where users come from, what they do inside your product, which features they use, where they drop off, and which actions lead to activation, retention, or conversion.
