This is an open source leaderboard and achievements system which you can easily host yourself.
The HighScoreService Class can be used for HTML5 games, where a simple cloud based highscore and leaderboard system is needed. For smaller games it may not be an option to depend on Google's or Apple's game services. The implementation has no other dependencies than the parse.com api client.
Features:
- Manage players (Users)
- Player specific highscores
- Track players game time
- Manage achievements for players
- Leaderboard
- Store game specific values to the detail objects of achievement and highscore entities
