Simple self-hosted web visitors counter.
- It tries to count how many unique users accessed different pages on a website, without looking at or storing any personal information.
- Only one random UUID cookie is used.
- One user using multiple web browsers or devices cannot be tracked and will be counted as multiple users.
- The cookie expires after 30 days and next access will be counted as new user.
- The counter has no way to prevent fake entries to be added by bad actors, but should be otherwise secure.
- Access to the statistics is not restricted.
Requirements: webserver with PHP and MariaDB/MySQL.
- Change DB settings in nano-analytics.php and save it to root of your website.
- Create database using setup.sql
- Include nano-analytics.js in all pages where you want to collect statistics.
- Open /nano-analytics.php to see the statistics
