LoupeKit vs Hoverify: which one should you install?
Hoverify is the closest thing on this list to what LoupeKit is trying to be, and it got there first. Hover-to-inspect, responsive frames, asset extraction, stack detection, code injection and SEO in one panel, on Chrome and Firefox, for a yearly price or one lifetime payment. Around twenty-two thousand developers use it. This page is narrower than the others because the products are closer.
A polished hover loop and code injection: Hoverify. Whole-page diagnostics, evidence per detection and a free tier: LoupeKit.
Hoverify
Yearly or lifetime · 22,000+ developers · Chromium and Firefox
An all-in-one developer extension with a long head start. Inspect by hovering, test across device frames, pull assets, read the stack, inject CSS and JavaScript, take full-page screenshots, check SEO tags. Three activations on the paid plan and a fourteen-day refund window, both stated plainly on their site.
LoupeKit
Free tier · nine surfaces · Chromium and Firefox
The same shape, with the weight in different places: detection that shows the evidence for every match, sixty-three named tools and diagnostics that rank what to look at rather than waiting to be asked, an accessibility surface that produces a WCAG statement, and an audit that scores how much of the markup reads as generated.
Feature by feature
4 of 10 rows differ · they are the shaded onesWhere LoupeKit stops, and why
1 of the rows above · each one is a decision- JavaScript injection
- An MV3 extension runs under `script-src ‘self’`, so script it injects into a page is script the browser refuses. Site styles are the half that can be done properly: a stylesheet per origin, put back whenever LoupeKit is running there.

Pick Hoverify if
If you want to inject JavaScript into a page, which it does and we will not - an MV3 extension cannot run injected script under its own content-security policy, and ours saves a stylesheet per site instead. Or if the hover-inspect loop is most of your day - that is the interaction it has spent years on. It is also the safer bet on maturity: it has been shipping for longer, to more people, and a tool you will open every day is a reasonable place to value that.
Pick LoupeKit if
If you want to work before deciding whether to pay, if a detection is only useful when you can see why it fired, or if the questions you have are about the page as a whole - what it ships, what it fails, how much of it was generated - rather than about the element under the cursor.
Run both
Uncommon but not silly: our free tier costs nothing, so keeping Hoverify for script injection and reaching for this when the question is about the whole page is a workable arrangement.
