Official portable apps

So, what you're looking for is not whether or not the application conforms to the published PA.c standards, correct?

I tried looking for things that are different between BleachBit and LibreOffice. The notable differences that could be referred to are:

1) BleachBit is hosted through SourceForge, while LibreOffice is hosted through the Document Foundation
2) BleachBit has a single executable and of course LibreOffice has many
3) Custom NSH code differences

The most likely question is that farat_as was asking which applications are "officially endorsed" versions of their apps; probably referring to their hosting source. To that end, the answer is still the same: all of the applications listed are available because their are free and open source (probably with explicit permission), freeware with permission for bundling or online installer, or developed by developers who work directly with PortableApps.com (like the dotNet Inspector developed by winterblood).

Just because an app calls itself portable does not mean it is in PortableApps' format or adheres to PortableApps standards. Companies and developers are free to adhere to PortableApps's format but they are not required to. The ones that do are listed on the Apps page linked to previously.

There are multiple levels of official support. Some developers build and release the PortableApps.com Format version themselves. These include TeamViewer, Database Browser, Task Coach and others. Some developers have us build it for them and then they host it. LibreOffice, Inkscape, Scribus and some others fit in there. Some developers have us build and host it and then link to us as the official portable version or one of the portable versions. This includes FocusWriter, PeaZip, RedNotebook, and others. Some developers give us specific permission to build a portable version of their apps and distribute them. This includes Firefox, Thunderbird, IcoFX, XnView, and others. And finally, some apps we bundle under the open source licenses they come with without assistance from the publisher.
