Spider-Lens is a free, open-source application for analyzing Apache and Nginx server logs. It monitors traffic, HTTP errors, crawler bots and server performance through a dashboard covering requests, human visits, error rates, HTTP status trends, bot distribution and 12-week patterns. Crawler monitoring detects 16 or more bots and shows crawl budget and crawler volume. Performance reports include Time to First Byte by URL, configurable slow thresholds and CSV or Excel export. A sitemap crawler follows internal links and records titles, H1 headings, word counts, canonicals, robots directives and crawl depth. SMTP alerts and webhooks can report 404 spikes, server errors, missing Googlebot and weekly summaries. The project documents Discord, Slack and an MCP server integration. It runs as a Node.js application or native WordPress plugin, with no Node.js required for the plugin. Node deployment requires Node.js 18+, npm 9+ and log access. The interface lists 16 languages and automatic browser-language detection. Nova uses Gemini when configured.
