CargoCollective is an interesting service in that they offer you elegant and sophisticated websites for free but on a curated basis - you have to apply and be approved.
This is very different from most of the free website and portfolio services we feature on WeLikeArtists.com The advantage is that the quality of sites, and the artists who present their work on them, is very high. We asked them what their assessment criteria were, but didn't hear back from them, so it is anyone's guess.
Launched in 2009, it has some longevity and aims to host the work of "..the most talented individuals currently publishing their work online". They offer a free service (once you have been accepted into the collective) which lets you present up to 12 projects. If you would like more control, be able to adapt the code and also show more works you can upgrade to a more sophisticated package for £44.00 per year.
One of our previously featured artists, Katrine Brosnan has been using them for a while and is really pleased with the platform. She had previously used WordPress but wanted something simple to navigate and CargoCollective provided that.
If you want to be part of a curated community and have a clear art background, it is probably worth applying for a site.
