Questions
How the tools work
Are Stackra's website tools free?
Yes. Most of the focused checkers run a few checks without an account, the Website Speed Test needs no account at all, and a free Stackra account runs fresh scans. Each tool runs the relevant part of a full website scan: tech stack detection, schema and structured data, robots.txt and sitemap, meta tags, security headers, Core Web Vitals, accessibility, and design. A few deeper features that depend on licensed datasets, such as keyword intelligence and competitor comparison, are part of the paid Starter and Pro plans. Your own Search Console, Analytics, and Bing data is on every plan, Free included.
What is the difference between a single tool and the full website scan?
A single tool shows you one slice of your website's health, such as which technologies it runs on or whether its structured data is valid. The full Stackra scan runs every check, scores three pillars (Conversion and Trust, Search Visibility, Technical Confidence) into a single Growth Readiness Score, adds AI expert reviews from CMO, SEO, and CTO viewpoints, and produces a prioritized action plan. Because every tool reads from the same scan engine, the results line up with what the full report would show.
Do the tools run a fresh scan every time?
Not always. When a recent scan of the same URL already contains the data a tool needs, Stackra reuses it instead of scanning again. This makes repeat checks fast and avoids unnecessary load on your site. If the data is missing or out of date, the tool runs its own check of your site. A tool check is not a full report: the full report is its own scan.
Which website tools does Stackra offer?
Stackra is building focused tools across several areas: AI website review, design and first-impression review, SEO checks (meta tags, robots.txt and sitemap), AI visibility and structured data, performance (Core Web Vitals), technical health (security headers, accessibility), tech stack detection, and keyword and competitor intelligence on the paid plans. New tools are added over time and appear on the tools hub as they go live.
