Scattered tools
SEO here, accessibility there, security and compliance somewhere else: auditing a whole website means juggling lots of tools and just as many tabs.

WEB AUDIT PRO
A complete website audit, in one click, right from your browser.

The reality
Auditing a website today
means juggling too many tools.
SEO, performance, accessibility, security, compliance: every aspect of a website has its own tool, often paid, often hosted somewhere other than your own systems.
Data that ends up in the cloud
Most online scanners send the URL, and sometimes the content, of your pages to third-party servers before giving you an answer.
Results that are hard to present
Scattered technical scores don’t make a report: you still have to pull them together to share them with a client or a team.
The Web Audit Pro promise
Web Audit Pro isn’t yet another cloud service. It’s an audit engine installed on your computer, backed by built-in AI, to analyze a website inside out without ever exposing your data to a third party.
The analyzers
15 analyzers, one single click
With one click on the extension icon, Web Audit Pro analyzes the website open in your browser: from technical aspects to content, from legal compliance to the page’s ability to convert visitors. Here is what gets checked, analyzer by analyzer.

Local AI
Six AI models, on your computer
The models train directly on your machine the first time you launch it, from built-in corpora, then warm up in the background. No calls to any external AI service.
Continuous learning, locally
With every audit, the AI grows its own corpus on your computer. It stays cautious: an example is only kept if two independent sources agree, with deduplication and a size cap.
Model 1
Sensationalism
Assesses the page’s editorial credibility and feeds the Fake News tab.
Model 2
Priority
Ranks each action as high, medium or low priority, within a fixed rule: the AI can only deviate from it by one level.
Model 3
Scams & phishing
Spots signs of scams and phishing in the analyzed content.
Model 4
Keyword stuffing
Detects over-optimization of the title, description and H1.
Model 5
Effort
Estimates the effort of each recommended action: low, medium or high.
Model 6
Disinformation
Matches content against a database of known hoaxes: health, climate, 5G, cryptocurrencies…
Dedicated tab
Fake News Detector
Paste a text or an article’s URL: the page is fetched locally, then analyzed.
- A score combining local AI with explainable linguistic signals
- Matching against a database of known hoaxes (health, climate, 5G, cryptocurrencies…)
- Four graded verdicts, plus a special case for satirical websites
Beyond the audit

compare and track.
The extension opens on four tabs — Technologies, Audit, Fake News and About — in dark or light mode. Here’s everything it does on top of the scores.

Usage
An auditor that stays with you over time
A one-off audit says nothing about a website’s trajectory. Web Audit Pro is used at three key moments in the life cycle of a web project.
Validate a website before launch
Clean SEO, sound accessibility, security headers and GDPR/nFADP compliance in place: check that a website is ready before launch.
Make your case with facts
Compare their website with a competitor’s and hand them a white-label PDF report, clear and prioritized by topic.
Track progress
Run a new audit after each update and track how your scores evolve with the history.
Who it’s for
Built for the people who build the web
Web agencies
Branded PDF reports, handed to clients after every audit or redesign.
Freelancers
A full audit in one click to qualify a prospect and price the fixes.
SMEs, small businesses and nonprofits
Understand where their website stands and what to fix first, without the jargon.
Public bodies and platforms
Audit a portfolio of websites automatically with the self-hostable HTTP API.
Feature #02
A local engine, built-in AI
Instead of sending your audits to a remote server, Web Audit Pro relies on an analysis engine installed directly on your Windows computer. The extension talks to it locally, and the six AI models backing it also run on your machine.
An architecture designed for privacy: your audits, and your clients’ audits, stay with you.
- The analysis and the AI run on your computer
- Page data is only sent to the local engine
- The only network requests go to the audited website
- History, settings and white-label branding stored locally in the browser
SSRF protection
The engine refuses to act as a relay into your internal network, even if an audited website tries to push it there.
- Private IP addresses blocked
- Protection against DNS rebinding
- Every redirect revalidated
Fallback mode without the engine
Without the local engine, the extension still runs an audit in the browser.
- SEO, performance, accessibility, best practices, security
- Links, structured data, readability and EcoIndex
- AI, crawling and the action plan remain exclusive to the local engine
Self-hostable HTTP API
The same engine can run as an HTTP service on your own infrastructure, so you can automate your audits.
- Analysis endpoint and health check
- Optional API key
- Ideal for auditing a portfolio of websites
