Profile Website for Bot Detection Vendors Analyzes a target website to identify bot detection vendors, their specific products, and challenge types. Supports comparative analysis between stealth and non-stealth browser modes. Prerequisites Kernel CLI installed and authenticated Node.js 22+ installed jq installed ( brew install jq or apt install jq ) KERNEL_API_KEY environment variable set. If it is not set, prompt the user to supply. Comparative Workflow (Recommended) Compare bot detection behavior between stealth and non-stealth browsers to evaluate stealth effectiveness. Step 1: Create Both Browser Types

Create stealth browser (with -s flag)

kernel browsers create -s --viewport 1920x1080@25 -t 300

Save session_id as STEALTH_ID

Create non-stealth headful browser (no -s flag)

kernel browsers create --viewport 1920x1080@25 -t 300

Save session_id as NORMAL_ID

Step 2: Run Analysis on Both Browsers cd scripts npm install

first run only

Test with stealth browser

KERNEL_API_KEY

$KERNEL_API_KEY KERNEL_BROWSER_ID = $STEALTH_ID TARGET_URL = < url

BROWSER_MODE

stealth npm run analyze

Test with non-stealth browser

KERNEL_API_KEY

$KERNEL_API_KEY KERNEL_BROWSER_ID = $NORMAL_ID TARGET_URL = < url

BROWSER_MODE

normal npm run analyze Step 3: Compare Results Compare the vendor detections and blocking behavior:

Set the hostname folder (e.g., chase-com for chase.com)

HOST

chase-com

Quick verdict comparison

echo "=== STEALTH VERDICT ===" && cat output/ $HOST /stealth/report-.json | jq '.summary.verdict' echo "=== NORMAL VERDICT ===" && cat output/ $HOST /normal/report-.json | jq '.summary.verdict'

Compare block status

echo "=== STEALTH BLOCKED ===" && cat output/ $HOST /stealth/report-.json | jq '.summary | {isBlocked, blockedPages, blockedVendors}' echo "=== NORMAL BLOCKED ===" && cat output/ $HOST /normal/report-.json | jq '.summary | {isBlocked, blockedPages, blockedVendors}'

Compare detected vendors

echo "=== STEALTH VENDORS ===" && cat output/ $HOST /stealth/report-.json | jq '.summary.vendorNames' echo "=== NORMAL VENDORS ===" && cat output/ $HOST /normal/report-.json | jq '.summary.vendorNames' Step 4: Interpret Comparison Scenario Stealth Normal Meaning No vendors detected 0 0 Site has no bot detection Same vendors, no blocks N N Bot detection present, both pass Normal blocked, stealth passes 0 blocks Blocked Stealth mode is effective Both blocked Blocked Blocked Bot detection defeats stealth Different challenge types Lighter Harder Stealth reduces suspicion Step 5: Provide Summary After running the comparative analysis, provide a detailed summary report to the user that includes: Summary Report Template:

Bot Detection Comparative Analysis: [TARGET_URL]

Verdict

• Stealth Browser: [verdict from summary.verdict]
• Normal Browser: [verdict from summary.verdict]
• Stealth Effectiveness: [Effective/Ineffective/Inconclusive]
