Every feature, explained

Broken link detection

Every internal and external link checked using a real Chromium browser. Catches issues that raw fetch requests miss.

HTTP status codes

Every link returns its real HTTP status — 404, 403, 500, 301. You see exactly what the server returns.

Missing image detection

Finds images that fail to load, have empty src attributes, or have zero natural dimensions after the page renders.

Anchor text deception check

Flags links where visible text mentions a trusted brand but the href points to a different domain.

Title tag analysis

Checks presence, length (30-60 chars ideal), and duplication. Flags missing or oversized titles.

Meta description check

Validates presence and length (120-160 chars). Flags missing or truncated descriptions.

Heading structure

Extracts all H1-H6 tags. Flags missing H1, multiple H1s, and heading hierarchy issues.

Canonical tag validation

Checks for missing or self-referencing canonical tags that cause duplicate content issues.

Alt text audit

Reports every image missing an alt attribute with its exact DOM location.

Content quality scoring

Detects thin content (under 300 words), duplicate blocks, and low uniqueness scores.

Google Safe Browsing

Deep scan checks all outbound links against Google Safe Browsing API v4 — phishing, malware, unwanted software.

Hidden iframe detection

Flags iframes with zero dimensions or display:none — classic technique for loading malicious content invisibly.

Suspicious TLD detection

Flags links to high-risk TLDs (.tk, .ml, .ga, .cf, .xyz) commonly used in phishing campaigns.

Redirect chain analysis

Traces full redirect chains. Flags chains longer than 3 hops and chains ending on suspicious domains.

QA score (0-100)

Every scan produces a numeric score based on issue severity. Track improvement over time per project.

AI issue explanations

Each issue gets a Claude-generated explanation: why it matters, fix steps, code example, and effort estimate.

Scan diff tracking

Re-scan any project and see exactly what changed: new, resolved, and regressed issues.

Issue status tracking

Mark any issue as open, resolved, or ignored. Status persists across scans.

HTML + JSON export

Full HTML report for client delivery and machine-readable JSON for CI pipelines.

Scheduled scans

Configure daily or weekly automatic scans per project. Server checks every hour and triggers when due.

Regression alerts

Get emailed immediately when a scheduled scan finds new critical or high severity issues.

Weekly digest

Every Monday: summary email covering all monitored projects, QA score, open and resolved issues.

A/B URL comparison

Scan two URLs simultaneously — perfect for staging vs production or before/after deploys.

Full-page screenshots

Every scan captures a full-page screenshot. Visual before/after comparison per project.
