HashOver is a PHP comment system intended as a replacement for services like Disqus. HashOver is free and open source software, under the GNU Affero General Public License. HashOver adds a "comment section" to any website, by placing a few simple lines of JavaScript or PHP to the source code of any webpage. HashOver is a self-hosted system and allows completely anonymous comments to be posted, the only required information is the comment itself.

Although most PHP installations include everything HashOver requires by default, depending on your setup you may need to install some modules/extensions and/or ensure PHP was compiled with support for the following modules.
| Feature | Module name(s) | Debian/Ubuntu package name(s) |
|---|---|---|
| Date and Time | date | part of PHP core |
| Document Object Model | dom | part of PHP core |
| Regular Expressions | pcre | part of PHP core |
| User information encryption | openssl | part of PHP core |
| Multi-byte character support | mbstring | php-mbstring |
| Internationalisation | intl | php-intl |
| XML data storage format support | xml, libxml, SimpleXML | php-xml |
| JSON data storage format support | json | php-json |
The following modules are optional
| Feature | Module name(s) | Debian/Ubuntu package name(s) |
|---|---|---|
| PHP Data Objects | PDO | php-sqlite3, php-mysql |
| SQLite file format support | pdo_sqlite, sqlite3 | php-sqlite3 |
On UNIX (GNU, BSD, etc) you may list installed modules with this command:
php -mOn Windows the command to list installed modules is:
php.exe -mhashover.php is no longer used in JavaScript tags, the file
/hashover/comments.php is used instead.
So change:
<script type="text/javascript" src="https://github.com/jacobwb/hashover-next/raw/master/hashover.php"></script>To:
<script type="text/javascript" src="https://github.com/jacobwb/hashover-next/raw/master/hashover/comments.php"></script>The pages directory is now comments/threads, this change will cause
existing comments to not appear until you move the directories under pages
into the new comments/threads directory.
All JSON config files have been moved to the new config directory, you will
need to move the files hashover/blocklist.json and
hashover/ignored-queries.json into the new config directory. If these
files do not exist, you don't need to do anything as these config files are
completely optional.
The previously removed secrets.php file has returned. The required setup
information, namely the notification e-mail address, encryption key, and the
admin username and password are now stored in this secrets.php file located
at /hashover/backend/classes/secrets.php.
You will need to move the values of the public properties
$notificationEmail, $encryptionKey, $adminName, and $adminPassword in
the settings.php file into the new protected properties in the secrets.php
file, and remove these properties from settings.php or replace the
settings.php file entirely, as its source code is publicly viewable, whereas
the source code of secrets.php is not.
Windows will be officially supported by HashOver 2.0, there should not be any major issues with using HashOver on Windows. However, HashOver is primarily developed on and for UNIX operating systems, which are the primary operating systems used by the majority of web servers. If you have any issues with HashOver on Windows, please report them.
