Top OpenSim Hosts of 2009

The choice of OpenSim hosting companies has grown a bit but is still very limited, due to the fact that the OpenSim platform has only become stable — and grids hyperlinked — at the start of this year.

If you’re looking for a free alternative to a paid hosting services, see  Free Land in OpenSim and OpenSim deployment gets easier.

If you want to outsource this function and save yourself time and worry, here are today’s top options, in no particular order:


Best for: Schools, businesses. ReactionGrid has a very strong educational community on it, and also offers a selection of tools and other products to assist groups in setting up their grids. The folks behind ReactionGrid work hard to maintain good relationships with their customers, and on ensuring the stability of the public and private grids they operate. Their customers rave about the service they get, and the ReactionGrid executives can usually be found on the grid itself, answering questions, solving problems, and running events.

Prices: Start at $25 per region (16 acres, average use) with a $25 setup fee.
