Website quality intelligence, from scan to resolution.
Stop stitching together disconnected Lighthouse runs, SEO checklists, and broken link scrapers. ScanFix is an unified engineering platform that scans, investigates, and monitors website quality.
Deterministic lifecycle: URL to verified resolution.
Every audit undergoes strict sequential execution ensuring repeatable, mathematical scores.
Discover
Protocol validation, DNS verification, and SSRF containment.
Crawl
Headless Chromium execution, console capture, and mobile rendering.
Analyze
Deterministic 6-dimension rule validation against standards.
Normalize
Standardized finding records and SHA-256 issue fingerprints.
Score
Monotonic severity penalty calculations from 0 to 100.
Investigate
AI evidence synthesis and framework root-cause analysis.
Remediate
Actionable code patches, DOM selector guidance, and diffs.
Verify
Immediate re-auditing to mathematically prove issue resolution.
Engineered for technical precision.
Everything engineering teams and digital agencies need to understand why websites break.
Headless Browser Scanning
Real Chromium DOM execution with network waterfall inspection.
- Executes live JavaScript and simulates real-world 4G/desktop network conditions
- Captures full network waterfalls, response headers, and layout timings
- Enforces socket-level SSRF defense to protect internal IP ranges and metadata APIs
6-Dimension Evaluation
Comprehensive automated audits without stitching disconnected tools.
- Core Web Vitals: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), INP
- Technical SEO: Canonical tags, XML sitemaps, robots directives, structured data
- Accessibility: Full WCAG 2.1 AA/AAA compliance, contrast ratios, keyboard trees
- Transport Security: Content Security Policy (CSP), HSTS preload, secure cookies
- User Experience: Viewport responsiveness, tap target spacing, layout shifts
- Technical Quality: DOM tree depth, JavaScript console errors, asset compression
Deterministic Findings Model
Normalized telemetry with immutable issue fingerprints.
- Every finding includes exact CSS selector paths and offending HTML snippets
- Calculates SHA-256 issue fingerprints for exact cross-scan tracking
- Applies monotonic severity penalty scoring from 0 to 100 with zero random drift
AI Root-Cause Investigation
Evidence-grounded diagnostic reasoning that understands code context.
- Multi-provider cascading engine across OpenAI, Anthropic, and Groq
- Synthesizes raw DOM evidence into plausible engineering root causes
- Generates actionable code proposals tailored to Next.js, React, Astro, or WordPress
Continuous Quality Monitoring
Scheduled recurring audits that catch regressions before clients do.
- Configurable IANA timezone cron schedules (daily, weekly, or custom intervals)
- Golden baseline preservation prevents failed scans from corrupting history
- Automated email and webhook regression alerts when score drops exceed thresholds
Executive & Agency Reporting
Client-ready PDF proposals and white-label client portals.
- Generate branded audit proposals with itemized fee estimates in one click
- Client-scoped portal views with restricted read-only permissions
- Historical timeline comparisons showing measurable quality improvements over time
For Developers & DevOps
DOM-level selectors, unified diff proposals, GitHub PR integration, and native CLI gate execution (`shipcheck`) directly inside your CI/CD pipelines.
For Digital Agencies
Multi-tenant client organization mapping, custom white-label reports, automated monthly retainers, and client-scoped read-only dashboards.
