The current list of plugins on their site is:

Stay tuned for complete Spriter file support coming soon for:
•Construct (already in public Beta!)
•Construct 2 (preliminary stages)
•Torque (7% in development)
•Unity 3D (5% in development)
Other future plug-ins will include:
•Multimedia Fusion
•Dark Basic
•Game Maker
•Unreal Engine
"
Which seems to suggest only Construct has a plugin so far...
The file format is simple so I figure any one of us could provide a set of tools for this right now. TGC could go ahead and add some built in commands but I doubt they would be too hard to write:

Spriter's Open, Universal File Format
Spriter game animations won't be tied to a specific development tool. Spriter saves to a fully open XML based format we call SCML, which is an acronym for Spriter Character Markup Language. Our intention is to get Spriter animation supported on every major game authoring tool. So far, we have a feature complete Scirra Construct Classic plugin in beta for creating DirectX 9 games with Spriter. Work has begun by third parties on Unity and Torque2d support for Spriter animations, which means soon Spriter animated characters could be possible on PC, Mac, PS3, XBOX360, Wii, Android, iOS, and Flash.
Anything that can read XML and display images in different positions, can support Spriter animation. With the early version of the plugin we're developing for Scirra's amazing HTML5 game creator Construct 2, we've actually managed to load and animate a Spriter character in a standard HTML5/javascript webpage, this is without using any special plugins - just a stock browser. We are also pursuing support on GameMaker, MMF2, DarkBasic, and other popular game engines.
In addition to the plugins and extensions we will be creating in house or outsourcing to a third party, we will provide full documentation of the file specification and free support on our forums to anyone who wants to integrate Spriter animation support into any game authoring tool or programming language, including their own proprietary game engine."
