See what Fusebox sees
Five representative sites, three demo scans — this is the actual extension view, preloaded with saved reports. Click around.
Fuseboxnova-pilot.appA Lovable-built marketing site deployed on Vercel. The domain is 19 days old with no archive history and light, typical tracking. The product may well be real — the company just has no track record yet, so treat bold claims accordingly.
Brand-new domains deserve extra scrutiny.
Vibe-coded isn't bad — but shipping fast isn't a track record.
Pick a question — the preview panel on the right updates, and it follows along as you scroll.
Every tab up top is clickable — WHOIS, DNS, Trackers, even the raw source. Same UI as the real extension, preloaded with saved scans.
Illustrative example sites, not real businesses.
Saved representative data
See the full workflow before you buy.
Demo reports show the complete tabs, evidence 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 same report 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 verdict right in the sidebar — on your machine. No API key, no tokens, no cloud.
Works for everyone: the verdict 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.

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
Verdict
Fusebox opens with an answer, not tabs. A short verdict plus 3–5 recommended actions, computed from every report below. Where Chrome's on-device AI is available, it rewrites the findings into a plain-English narrative — streamed live.

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

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

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

The three bets that make Fusebox different
Verdict, not tabs
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 verdict 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.

- See your own stack, hosting, and settings explained in plain English

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 hands you the verdict, 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.

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 verdict and its recommended actions
- 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

Local by default; external by choice
The narrative verdict 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.
