AWStats is a free, GPL-licensed log analyzer that turns web, FTP, and mail server logs into detailed traffic and visitor statistics.
AWStats is a free, open-source log file analyzer created by Laurent Destailleur and first released in 2000. It generates advanced graphical statistics from web, streaming, FTP, and mail server logs, running as either a CGI script or from the command line.
AWStats reports on unique visitors, visit duration, traffic by day/hour and by domain/country, and the most-viewed and entry/exit pages, along with browser and OS detection covering 97+ browsers and 35+ operating systems.
It also detects robots and worm/attack traffic, tracks search engine referrals and keywords, reports HTTP errors, and supports GeoIP-based location reporting across multiple log formats including Apache NCSA/CLF, IIS W3C, and WebStar.
AWStats is distributed under the GNU General Public License and is used by sysadmins, webmasters, and hosting providers who want free, self-hosted log analytics without sending data to a third party. It requires a Perl 5 interpreter with CGI support and runs on Windows, Unix, and Linux.
Yes, AWStats is free and open source, distributed under the GNU General Public License, including for commercial use.
Version 8.0, released in 2025, was announced as the last version the original author will personally maintain; the project points users toward Matomo as an actively maintained alternative.
AWStats supports Apache NCSA/Combined Log Format, IIS W3C, and WebStar log formats, among others.
The AWStats project itself recommends Matomo as an actively maintained alternative for ongoing web analytics.
