Web sites and game hubs
Freeciv.org
The Origin of the Freecivs. This is where it all started, although it is more of a technical site and less of a community hub. Contains forum with all technical announcement about native client ("Application"/"Program") versions. Obviously, this forum is also considered the central communication nexus for all sub-communities.
Longturn.net
The inventors of the longturn "sub-genre". Established in 2003, requires "native client", or application that can be downloaded from several sites. Ruleset development and very inclusive environment. Organises games with several ruleset branches. Aiming to develop a stable web version. Welcomes developers at all levels.
Freecivweb.org
Browser version of the game, concept started in 2017, this web site active since 2019. No downloads needed. Runs only one ruleset branch.
Tactics & Triumph
A spinoff from Freeciv Web, 99% identical, but developing its own ruleset branch in order to add variety to the game.
Freecivweb.com
Web version of the native client (no download needed), still requires some fine-tuning and final touches, but the most prospective technology at the moment.
Fciv.net
An attempt at web 3D version of the game. Doesn't offer multiplayer yet.
Movingborders
