LoupeKit
LoupeKit is a browser extension that lets developers read and understand the web page already open: what it is built with, how it is styled, how accessible and performant it is, and how much its markup resembles raw AI output. It performs inspection and extraction in the browser, with no website permissions at install and no background collection.

Products & Services
A Chrome/Chromium, Firefox and Edge developer inspector for the current tab. It detects web technologies and evidence, audits AI-like markup patterns, inspects and edits elements live, extracts palette/fonts/assets, tests viewports, and provides tools and diagnostics.
Free tier with unlimited inspector, extraction and browser-based tools, plus three Vibe Audits per device and no account required.
Paid monthly or lifetime tier that removes the audit counter and unlocks full finding breakdowns, reports, advisories, baselines, evidence packs, server probes, field data and other marked Pro capabilities.
Market Position
LoupeKit positions itself as an on-page, evidence-first alternative to repo linters, paste-your-code analyzers and AI guesses: it reads the tab the user is viewing, links findings to actual elements, and avoids broad website permissions. Its comparison materials position it against tools such as Wappalyzer, CSS Peeper, CSS Scan, VisBug and browser DevTools, combining stack detection with AI-vibe auditing, design extraction, accessibility/SEO analysis and reversible edits.

Executive Team
Ján Turský
Creator / developer
Mobile and frontend developer; creator of LoupeKit and Apptiary frontend developer since 2026. Previous roles include senior mobile development at OrderLord and REEF and mobile/frontend development at BiteBerry.
Founding Story
Ján Turský said he kept encountering pages where something felt wrong but lacked a practical way to inspect a page he did not own. Existing options were repo linters, paste-your-code tools, or model guesses; he built LoupeKit as a one-click, on-page check with evidence, actionable findings, and click-to-element navigation. A central founding decision was avoiding website permissions at install.
