OpenSim is a BSD Licensed Open Source project to develop a functioning virtual worlds server platform capable of supporting multiple clients and servers in a heterogeneous grid structure. OpenSim is written in C#, and can run under Mono or the Microsoft .NET runtimes.

IRC move

We are in the process of moving the IRC channel we use (#opensim) from EFNET to Freenode. If you can't find us on EFNET, get yourself over to Freenode! (There's also an #opensim-dev channel, also on Freenode, for those who are interested in digging into the guts of the code.)

OpenSim 0.4 Released!

The OpenSim team is happy to announce the first alpha release of OpenSim, version 0.4.5. This release focuses on stand-alone mode (with one or more regions). Some stuff works, a lot doesn't. If it breaks, you get to keep both pieces.

Stuff that works:

• standalone mode with one or more regions
• basic physics (no object collisions)
• persistence of users, prims, assets, and inventory via sqlite
• basic building, custom-texture uploads
• avatar editing
• See OpenSim: Testing

More advanced physics, in-world scripting, grid mode, and support for other database backends are not supported in this release, though they may work from time-to-time before crashing with an earth-shattering kaboom! All of these are under active development, and are being worked on for the 0.5.0 release.

Source distributions in both .tar.gz and .zip can be found at the OpenSim Downloads site.

Participating in the OpenSim Community

OpenSim is an open source project. This means that it is developed by anyone who wants to participate. This could be you! We welcome testers and developers alike. Please see the Contributions Policy for more details.

If you need help or want to help the best way to get in touch is IRC (chat network). There is a lot of activity there every day.

Getting online

There are at least two public grids and several standalone arrays running 24/7. For the casual user as well as those who want to run their own public regions, there is a list of available sims at OpenSim: Grids.

Also, the OpenSim developers hold office hours once a week in-world.

IRC

IRC on FreeNode, channel #OpenSim. Download an IRC client like X-Chat (or here for Windows) and go to FreeNode (server irc.freenode.net), channel #OpenSim. If you have Firefox, you can also use the Chatzilla IRC client (In the menu, Tools > Chatzilla). If you already have an IRC client installed you can just follow this link.

• Server: irc.freenode.net
• Channel: #opensim
