How it works
From a URL to a full stack
A fast public-page inspection with clear limits
01
Enter a public URL
Paste a homepage, landing page, or article URL. The checker normalizes the address before running the lookup.
02
Inspect visible clues
SearchVector checks public page signals such as scripts, headers, metadata, tags, fonts, and common platform fingerprints.
03
Review the stack
Read the detected categories, then use the findings to guide competitor analysis, migration planning, or a deeper SEO audit.
Built for Practical Research
A technology lookup should be useful even when a site hides part of its stack
Category-Based Results
See detections grouped by CMS, analytics, CDN, JavaScript, SEO, fonts, and related stack categories.
Competitor Research Ready
Check what tools competitors use for tracking, publishing, commerce, and site delivery.
Public Signal Method
Understand that detections come from public page evidence, not private source code or backend access.
Migration Planning
Use the stack snapshot before redesigns, CMS migrations, and vendor replacement conversations.
SEO Audit Context
Pair detected SEO plugins, analytics tags, and CDN clues with SearchVector audits and rank tracking.
Clear Caveats
Hidden headers, bundled code, blocked crawlers, and obfuscated assets can limit what any technology checker can prove.
