The record

Purpose: Spider-Lens analyzes Apache and Nginx server logs to monitor traffic, HTTP errors, crawler bots, and server performance.
SEO dashboard: The dashboard summarizes requests, human visits, bots, error rates, HTTP status trends, bot distribution, and 12-week trends.
Crawler monitoring: It detects 16 or more bots and visualizes crawl budget and crawler volume.
Performance analysis: It reports Time to First Byte per URL and supports configurable slow thresholds plus CSV and Excel exports.
Site crawler: The sitemap crawler follows internal links and extracts page titles, H1 headings, word counts, canonicals, robots directives, and crawl depth.
Alerts: Configurable SMTP email alerts and webhook notifications cover 404 spikes, server errors, missing Googlebot, and weekly reports.
Integrations: The project documents Discord and Slack webhooks and an MCP server for Claude Code or other MCP-compatible clients.
AI assistant: Nova uses Google Gemini and requires a Gemini API key; without one, the rest of the application works normally while Nova and AI Analysis show a configuration prompt.
AI data handling: The README says Nova does not send raw log data to Google and transmits only a compact JSON summary of about 500 tokens per request.
Security: Spider-Lens uses JWT authentication with a seven-day token and advises changing the default JWT secret and admin password before deployment.
Deployment: It is available as a standalone Node.js application and as a native WordPress plugin; the plugin does not require Node.js on the server.
Requirements: The Node.js application requires Node.js 18 or later, npm 9 or later, and access to Apache or Nginx log files.
Languages: The interface supports 16 listed languages and can detect the browser language automatically.
Maker: The repository identifies the maker as GDM-Pixel and lists Caen, France.
