SEO Log Auditor review
A focused, open-source tool for detailed crawl and log diagnostics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SEO Log Auditor is a local Streamlit application for analyzing nginx or Apache access logs for technical SEO insights. It is designed for SEO practitioners, developers, and teams auditing search-engine crawling behavior. Its seven views cover crawl-budget distribution, orphan URLs, status-code waste, stale pages, performance, bot verification, and parameter traps. Users can optionally provide a sitemap URL and inspect results locally without a cloud dependency.
The product uses an open-source pricing model: it is presented as free and licensed under the MIT license. The workflow centers on uploading a log export, with support for Grafana/Loki exports, CSV, and plain-text nginx logs. That local-first approach suits teams that want to keep analysis outside a hosted SaaS environment, while the upload-based input means it is oriented toward exported datasets rather than a direct log pipeline. The published plans show no separate paid tier or hosted package.
Its strongest fit is for teams that need detailed diagnostic coverage in one focused tool. Reports address crawl-budget distribution by page type and bot traffic, orphan URLs using bot-accessed URLs and sitemap signals, non-200 responses and redirects, stale URLs, page size, latency, hit frequency, Googlebot verification, and high-variance query strings. Teams seeking a free local analyzer with these SEO-specific views should consider it; teams looking for AI features, a hosted SaaS workflow, or a broader all-in-one platform should choose an alternative.
