CreRo is a CMS for record labels, and was initially written to power Crem Road records.

Full multi tiers architecture with through a simple setup the possibility to use external services such as Clewn Audio to host your (free download) media files - or host your files on your own server, you choose.

Paid download is very partially supported (no anti-stealing protection, see below).

Physical release shop feature.

Streaming only or online music free download.

Radio stream for your catalog ; with Xiph yellowpages registration.

Physical releases means free download, for now.

Chatroom including geolocated chatroom allowing your fans to network with like-minded listeners of their local area.

Sell your online digital music quick instructions: activate download_cart option. Maybe set is_download_cart_name_your_price for either, name your price no minimum, or name your price with minimum. Note that people downloading will get hotlinkable audio file links, with no auth system, and that there is no way to prevent them from passing the links around.

New feature : create a subdir called "supporters" and put an index.php that you can code as you wish in it if you want to display a hall of fame of your donators. A "Our supporters" link will display then in the donation module.

New Feature 17.03 there is now support for mp3 only catalogs (if you wish to host your audio on your own). Previously flac mp3 and ogg were all three mandatory.

Installation steps

Crash course ; free download albums, media files served by

  1. Clone the CreRo repository.

git clone

  1. edit ./admin/config.php and change username and password

  2. Deploy to your web server

  3. Check yourserver.tld/admin/d . If you don't get a HTTP 403 Forbidden, this means that .htaccess directives are not applied by your web server, and you'll need an alternate way to secure any sensitive data storage dir (especillay network/d/ e/ and f/ if you enable geolocated chats for your visitors)

  4. Go to yourserver.tld/admin/ and log in

  5. set the ''clewnapiurl'' and the ''clewnaudiourl'' to use as media tiers -you'll get the rights urls in the online help

  6. set ''server'' config option to reflect the path of your install ; set site ''title'', site ''description'', maybe page footer... It should be enough for now

  7. declare your artists list with the option called ''artists''

  8. use Cover Art section to upload your cover arts. Indicate each file's corresponding album in configuration options -> covers

  9. upload your audio files (same basename flac ogg mp3 with correctly set artist, album, title, comment tags) to

Hosting free download album on your own

Apply previous steps 1-5

  1. download php-getid3/ from (1.x version should always work) and put it at INSTALL ROOT/php-getid3

  2. put your audio in INSTALL ROOT/api/audio (same basename flac ogg mp3 with correct artist, album, title and comment tags)

  3. update ''clewnapiurl'' to http://your server/install path/api/api.php and ''clewnaudiourl'' to http://your server/install path/api/audio/ (mind the trailing slash)

  4. Same as previous scenario steps 8 and 9

Provide streaming only albums

  1. same id3 download as previous scenario step 1

  2. same audio upload as previous scenario step 2 but in INSTALL ROOT/z

  3. create an empty index.html in this very directory if you want to prevent public listing

  4. usual stuff for artist declaring and cover uploads

  2. optionnal : if you wish "name your price, no minimum", set this option, otherwise it will be "name your price, with minimum"

  3. declare whitlisted material artist in ''material_artist''. Maybe, blacklist some particular albums with ''material_blacklist''

Fan network's chatrooms, label radio, and so on

  1. refer to online help. Note that a bug in FF48 prevent your user to indicate their HTML5 geoloc currently (august 2016)

Understanding the system architecure

When we coded a real site for Crem Road records, we already had our material available from, a free download hosting we run. Then we created a Clewn API for CremRoad (and then CreRo) to query Clewn and pull audio media files from there.

CreRo can be used as well with Clewn wich hosts its free albums as with your own free albums media tiers running on your own server.

In both cases, the url of the api backend goes to clewnapiurl config option.

It is possible to restrict the acces to albums to streaming-only. Please note that your audios could be easily stolen. Be sure to add a blank i ndex.php file in <install root>/z/ to prevent public directory listing and put your streaming-only albums audio in this directory.

Remember that piracy actually increases sales :)

The general requirement for audio is that same basename files have to be there in flac, ogg and mp3 format, and that metadata tags should be set, especially "artist", "album", "title", "year" and "coment".

Concerning the free download audio, if you run a local media tier for free album storage, they have to be uploaded in <install root>/api/audio directory.

To host free audio by yourself or to host streaming only albums, you must download and install php-getID3, which is GPLed software primarily avaiable from Extract the php-getid3 archive directory at the root of your CreRo install.

The configuration options most commonly update - refer to admin panel for a more up-to-date liste with online help
