See what Fusebox sees
Five representative sites, three demo scans — explore the technical evidence layer with saved reports. Click around.
Pick a question — the preview panel on the right updates, and it follows along as you scroll.
Every technical tab is clickable — WHOIS, DNS, Trackers, even the raw source. The extension links here from its five visual reports.
Illustrative example sites, not real businesses.
Saved representative data
See the full workflow before you buy.
Demo reports show the complete evidence tabs, receipts, partial states, and Markdown export. Arbitrary-site scans unlock with a Fusebox license.
Trust check
Open it. Then verify it.
We are early, so we will not manufacture ratings or testimonials. The product, its evidence, and the guarantee should do the convincing.
Before you buy
Open the demo panel
Open three saved, representative scans and click through the technical evidence tabs, partial states, receipts, and Markdown export that the extension uses.
While you inspect
Read each circuit's receipts
Fusebox connects a conclusion to the signal it found: headers, scripts, DNS, RDAP, Wayback, tracker signatures, and page metadata.
After purchase
Open full access on your own sites
A paid license unlocks arbitrary-site scans. If Fusebox does not help you inspect websites as advertised, request a refund within 14 days—no explanation required.

Your AI can't see the live web.
Your browser can.
Fusebox packages what the browser already knows into context any AI can use.
The sidebar agent
Chrome's built-in AI writes your snapshot right in the sidebar — on your machine. No API key, no tokens, no cloud.
Works for everyone: the snapshot needs no AI. The narrative is the bonus on supported machines.
Copy report as Markdown
Paste live facts into Claude, Codex, ChatGPT, or Cursor. Facts, not vibes.

Problem scan
Fix your errors. Watch your rivals. See through the slop.
Other tools hand you a list of logos. Fusebox answers the question you actually have, with the evidence one scroll below.
Inspect 01
"Is this a real product?"
That slick startup site — a genuine product, or a weekend AI build with a 3-week-old domain? Fusebox tells you which.
Inspect 02
"Why does my site look broken when I share it?"
Point Fusebox at your own project to catch missing link previews, misconfigured basics, and other quiet mistakes — with a fix suggested for each.
Inspect 03
"Can I trust this checkout?"
Domain age, hosting, trackers, and history in one readout — the signals you actually check before handing over a card.
Inspect 04
"What did they build this with?"
See the tools and services powering any site you admire, so you can build something like it — with the receipts to prove each call.
Fusebox answers all of them for one $29 purchase
Feature receipts
All the technical data. None of the digging.
Every detection carries its evidence: the exact header, script, DNS record, or metadata it was based on. No vibe scores. No "trust the logo."
Report 01
Site snapshot
Fusebox opens with what stands out, then five stable visual reports. Suggested checks are computed from the evidence below. Where Chrome's on-device AI is available, it rewrites the findings into a plain-English narrative — streamed live.
- +Works for everyone — no AI required
- +On-device AI narrative when supported
- +Action chips deep-link to the evidence
Report 02
Origin
Was it vibe-coded? Fusebox catches AI builders — Lovable, v0, Bolt, Framer, Replit, Wix — from the fingerprints they leave behind, with a confidence level, never a fake score.
- +script cdn.gpteng.co · meta lovable-tagger
- +Confidence, not a made-up percentage
- +Honest: hand tools like Cursor are undetectable
Report 03
Hosting
Where a site actually lives — Vercel, Cloudflare, AWS, Netlify, and more — read from response headers, the CNAME chain, nameservers, and ASN owner.
- +header x-vercel-id · CNAME chain
- +Nameservers + ASN / network owner
- +Combined signals → a confidence level
Report 04
Tech Stack
Frameworks, meta-frameworks, CMS, ecommerce, analytics, payments, auth, fonts, and CDNs — detected from a clean-room fingerprint set built and maintained in-house.
- +270+ curated, evidence-backed fingerprints
- +Every match carries its evidence
- +No scraped logo lists
Report 05
Domain
How old the domain really is, who registered it, and how it resolves — real WHOIS over RDAP plus DNS records and the network owner behind the IP.
- +RDAP WHOIS: registrar, age, expiry, status
- +DNS records (A, MX, NS, TXT)
- +IP → ASN / network owner
Report 06
SEO
On-page SEO and social-preview metadata in one place — titles, meta descriptions, Open Graph, Twitter cards, JSON-LD, and heading structure.
- +Title, description & canonical
- +Open Graph / Twitter / JSON-LD
- +Heading outline at a glance
Report 07
Trackers
Who's watching. Around 60 tracker and pixel signatures, categorized, plus a rollup of every third-party domain the page talks to — with a one-line 'what it does' for each.
- +~60 tracker & pixel signatures
- +Third-party domain rollup
- +Category + plain-English purpose
Report 08
History
How long a site has really existed. Wayback Machine snapshot counts and first/last capture dates — a fresh page with zero history is a signal worth knowing.
- +Wayback snapshot count
- +First & last archived capture
- +Feeds the Identity snapshot
Report 09
Source viewer
Read the actual page source in a Monaco editor — the raw HTML, scripts, and metadata behind every detection, so you can verify the receipts yourself.
- +Full page source, syntax-highlighted

Fusebox gathers the receipts
Tech fingerprints, hosting signals, official domain records, trackers, and archive history — each detection tagged with its evidence and a confidence level.
Read the snapshot
A plain-English answer with recommended actions sits on top, the full reports one scroll below. On supported machines, an on-device AI writes the narrative.
The three bets that make Fusebox different
Signal before detail
Every competitor dumps data. Fusebox opens with an answer and the actions worth taking.
Receipts for every claim
Each detection shows the header, script, or DNS record it was based on — and a confidence level.
Local-first AI
Chrome's built-in Gemini Nano writes the snapshot on-device. No API key, no page data sent to a cloud LLM.
Built for the moments you need an answer fast
Vibe coders, makers, careful shoppers, marketers — anyone who needs to know what a website really is, without a computer-science degree.
For vibe coders
You can ship an app with Lovable or Cursor — Fusebox helps you understand what you shipped. Check your own site like a pro, learn what the pieces do, and troubleshoot without begging for help on Discord.
- "Why does my link look broken when I share it?"
- See your own stack, hosting, and settings explained in plain English
- Catch missing previews and quiet mistakes before your users do
- Learn what a CDN or tracker actually is — as you go
Stop juggling nine tabs to answer one question
It's all public information — if you know the right lookup, the right terminal command, and how to read the results. Fusebox gathers the whole picture in one scan and highlights what stands out, with receipts, for a one-time $29.
One scan replaces
…and the part no tab does for you: reading it all and telling you what it means.

$29 once. Not $29 a month.
The first time Fusebox saves you an hour of DNS, WHOIS, and view-source sleuthing — or stops you trusting a three-week-old vibe-coded "store" — it has paid for itself several times over.
Local-first by design: no browsing profiles, no background browsing-data uploads, and no subscription.

No spyware. Clear data flow.
Fusebox does not sell browsing history, build browsing profiles, or upload your page content in the background. Page analysis runs locally; named public lookups send only the domain or IP they need, and optional cloud AI receives only the context you choose.
No browsing-data harvesting
- The page's content, DOM, and metadata
- The deterministic snapshot and its suggested checks
- On-device AI narratives, when your machine supports them
- Preferences and conversations in browser storage; report results in extension memory
- Your browsing history — Fusebox does not build or sell browsing profiles
Named external calls
- dns.googleDNS records — sends the domain name
- RDAP.orgWHOIS / domain age — sends the domain name
- ipinfo.io + RIPEstatIP / ASN owner — sends an IP address
- archive.orgWayback history — sends the domain name
- Fusebox + StripeLicense and payment — sends license or checkout data, not browsing history
- OpenAI / VercelOptional cloud AI — sends selected prompts and report context
Local by default; external by choice
The narrative snapshot can use Chrome's built-in Gemini Nano — no API key and no report sent to a cloud LLM in that mode. If you turn on optional bring-your-own-key cloud AI, the report context you choose is sent to the provider you configure.
