LoupeKit

LoupeKit is a desktop browser extension that adds a floating panel over the current tab to read the page in front of you and surface a wide range of tooling: an inspector, extractors, stack detection, SEO and accessibility readers, visual overlays, diagnostics and a Vibe score that estimates how much of a page reads as AI-generated. It runs locally for most features (inspector, extractors, stack detection and many diagnostics) while a small subset of readings — audits, server probes, advisories and some field data — are performed by the service and are metered. LoupeKit is aimed at developers, designers, accessibility and SEO reviewers, and consultants who need to inspect sites (including staging and localhost), generate client-ready reports, and track baseline changes across visits.

Key Features

Floating panel with 70 tools and diagnostics

A draggable panel that contains seventy tools and diagnostics across multiple surfaces so you can inspect and run diagnostics without docking DevTools.

Vibe score (AI-generated content detection)

A Vibe audit computes a score that estimates how much of a page reads as generated using 66 heuristics across categories like markup, CSS, runtime, copy and accessibility.

Inspector and visual tooling

Inspect box model, contrast, focus path, z-index, overlays and modify elements on-page with reversible changes.

Stack and technology detection with evidence

Detects the technologies a page is built with and provides the selector, URL or header that matched along with published-version advisories.

Audits & reports (metered)

Server-run audits produce findings, full rule breakdowns, evidence packs and client-ready reports hosted at links with expiry; audits are the only metered requests.

Privacy-first permissions model

Installs with four core permissions (activeTab, storage, scripting, contextMenus), no host_permissions by default, no analytics, and stores a local device id rather than an account.

Cross-browser builds

Two shipped builds cover Firefox and Chromium-based browsers (Chrome, Edge, Brave, Opera, Arc, Vivaldi, Chromium, Opera GX).

Pricing

Free Tier Available

Free to read forever: inspector, extractors, stack detection, SEO and accessibility readers and most in-browser tools; includes three free audits that consume server requests.

Free

€0
  • Inspector, extractors and readers
  • Stack detection with evidence
  • Most tools and diagnostics that run on the document in your browser
  • Three free audits (metered)

Monthly (Pro)

€6.99 per month
  • Unlimited or additional audits (removes the three-audit free limit)
  • Client-ready reports and exportable evidence packs
  • Baselines, advisories and other Pro readings that require server requests

Lifetime (launch price)

€74.99 one-time (note: lifetime price shown rising to €119.99)
  • Same Pro feature set as the monthly plan with a single payment

Use Cases

Front-end debugging and design inspection

Use the inspector, overlays, box-model and CSS tools to find layout issues, z-index problems, overflow and rendering differences without leaving the page.

Accessibility reviews and WCAG evidence

Run accessibility readers and audits, export an accessibility readout or evidence pack for procurement and VPAT work (PRO feature).

Detecting AI-generated pages and refactoring

Run Vibe audits to see which parts of a page exhibit signals of generation and receive refactor suggestions tied to each finding.

Client reports and deliverables

Generate branded client-ready reports and timed evidence links that can be sent instead of screenshots (PRO feature).

Technology and vulnerability reconnaissance

Detect the page's stack, versions and associated advisories or CVEs to support security reviews.

Testing staging, localhost and authenticated pages

Reads the active tab on click, so it works on localhost, staging and pages behind logins without whitelists.

Integrations

Browsers & extension stores

Chrome (Chrome Web Store), Firefox (addons.mozilla.org, Firefox build), Edge (Microsoft Edge Add-ons) and other Chromium browsers (Brave, Opera, Arc, Vivaldi, Chromium, Opera GX) via the Chrome build.

Stripe (payments)

Payments are processed through Stripe; the site states Stripe is used and card numbers are not stored by LoupeKit.

Chrome UX Report (field data)

Field data from the Chrome UX Report is listed as one of the optional external readings the product may surface.

Benefits

Consolidates many developer, SEO and accessibility tools into a single extensible panel (one install, one permission list).
Privacy-focused: most tooling runs in the browser, no host permissions by default, no third-party analytics or scripts.
Cross-browser support across Chromium browsers and Firefox (desktop), enabling consistent tooling for teams.
Free tier is highly usable for inspection and reading; Pro unlocks exportable reports, evidence packs and unlimited audits.
Designed for client work with branded exports, baselines and time-stamped evidence for procurement and compliance workflows.

Limitations

Audits and a handful of readings (advisories, server probes, field data) are server-side and are metered; the free plan includes three free audits.
Safari and mobile browsers are not supported; shipped builds target desktop Chromium browsers and Firefox.
Some published features (advisories, sitemaps, hosted evidence links) depend on the LoupeKit infrastructure and would stop if the service were discontinued.

Frequently Asked Questions

How is the Vibe Score calculated?
The Vibe Score uses 66 heuristics across five weighted categories (markup, CSS, runtime, copy and accessibility). Each heuristic quotes the measured value that produced a partial score; the scoring runs on the server.
Is the free tier usable, or is it a demo?
Free is for looking and is usable: inspector, extractors, stack detection with evidence, SEO and accessibility readers, and tools that run on the open document. Pro is for taking data away and for server-metered readings like extra audits and exports.
Is Lifetime really a single payment?
Lifetime is sold as a one-time payment that carries the same feature set as the monthly plan; the site notes the lifetime launch price will rise to €119.99.
Do you offer refunds?
Refunds are offered within 14 days from payment; requests are handled by email.
Can I use it on client work?
Yes — the client report and branded export were designed for personal and commercial client work.
Which browsers does it run on?
Desktop builds are provided for Chrome (Chromium-based browsers) and Firefox (Firefox build requires version 140+); Safari is not shipped.

Getting Started

  1. 1 Install the extension for your browser (Chrome Web Store, Firefox Add-ons, Edge Add-ons; Chromium-based browsers use the Chrome build).
  2. 2 Click the toolbar icon to open the LoupeKit panel (the extension requests activeTab only when you click).
  3. 3 Use the command palette (⌘K / Ctrl+K) to find tools, run the inspector or run audits; upgrade to Pro if you need additional audits or export features.
