Analyze an Apache or Nginx combined access log in your browser. Review claimed bot requests, redirects, errors and optional sitemap coverage without uploading IP addresses.
Files and pasted content are processed locally, never uploaded or saved. Closing or refreshing clears them. Usage events contain the tool name and action only.
Export an uncompressed combined-format access log for one host. The sample shows the exact supported format.
Choose a claimed user-agent group and optionally add that host's page inventory. Analysis runs locally and output omits client IPs.
Review error responses and absent inventory paths. Verify bot identities and investigate missing requests separately; the log sample does not prove crawling or indexing problems.
The result tables preserve the observations behind each finding. Filter rows to focus your review, add notes to the main table and export a CSV. Use the text report to keep the method and limitations alongside the data.
A local diagnostic answers a bounded question about the input you provide. It does not prove how a search engine crawled, indexed or ranked your site. Follow up with a live check or the relevant first-party report when the decision depends on that evidence.
No. The tool processes the input in this browser tab. It does not upload, save or fetch the supplied URLs. Closing or refreshing clears your input. Basic tool-name/action events never include file contents, filenames, URLs or queries.
Yes. Load the worked example and run the check to see a clearly fictional input and its output. Replace the sample with your own data before making decisions.
User-agent names can be spoofed; no bot identity is verified. Maximum 5 MB, 50,000 lines. Custom formats, JSON and compressed files are unsupported. Dates are grouped in UTC.
Yes. Download every result table as CSV or save a text report with method notes. Reviewer notes appear in the corresponding table CSV. Exports escape formula-like cell values for safer spreadsheet use.
