About
Welcome to FreeSO!
FreeSO (“Free Simulator Online”) is a reimplementation of The Sims Online™‘s game engine using C# and Monogame. While FreeSO aims to be faithful to the original game, it includes many quality of life changes such as: hardware rendering, custom dynamic lighting, hi-res output, larger lot sizes, five story houses, and 3D mode!

FreeSO Archive goes even further, adding the ability for anyone to easily create, host and customize their own servers for friends to join, as well as a bunch of surprises that make it better than ever to play with a group of friends. However, FreeSO Archive is still in development! Check back regularly for more information, as development is nearing completion.
How to Play

The official FreeSO server shut down on December 9th 2024. The FreeSO Archive client will allow players to easily host their own servers without any technical knowledge, but it’s still in development. For more information on the shutdown and the Archive Client, check out these blog posts:
If you’re interested in hosting a FreeSO server in the full MMO mode, or using the Sandbox Mode and Volcanic, you should check out the documentation on GitHub and our source code. Note that you do need to roll your own solutions for the database, registration and client distribution, so it’s only appropriate if you want the full responsibility of hosting an MMO server.
A new version of the full server and client will be released with the FreeSO Archive client, so any modifications you make to the software in the meantime may need to be refactored to work with the improved client and server.

Fair Use Policy
On its own, the FreeSO client does not display any copyrighted material, and is not distributed with it. The game files are provided by the user, and the client simply reads the files the user provides. In this sense, our replacement client is essentially a glorified The Sims Online™ file reader, as all original graphics, sounds, UI layouts, and game objects are simply read and simulated by the client. The same goes for all our other tools and extensions for The Sims franchise games.
The game server transmits metadata generated from the execution of these scripts (avatar money values, lot/object state, avatar appearances, hash of the game files for version identification), but does not transmit any copyrighted material.
We will not accept any code or content that violates the policy above in our repo.
