What is psl-leaderboard-system?

PSL is a straightforward, open-source leaderboard system for games and apps. It lets you store player names and scores on a web server, then retrieve the full list back whenever you need to display rankings. If you're building a simple game in Unity or another engine and want a "high scores" table without building a whole backend, this handles that for you. The setup involves five PHP scripts that you upload to any web server with PHP and a MySQL database. You plug in your database credentials, run a setup page once to create the table, and then your game can submit scores by sending a web request to a URL like addScore.php?name=username&score=100. Retrieving all scores works the same way, your game calls getScore.php and gets back the full list. The README includes step-by-step screenshots for setting this up on a free hosting provider, aimed squarely at people with zero server experience. The target user is a solo game developer or hobbyist who needs a leaderboard fast and doesn't want to deal with authentication systems, cloud services, or backend frameworks. The included Unity/C# example shows the intended use case: call one method to add a score, call another to fetch them all. The big tradeoff is security, and the README is upfront about it. Scores are submitted through plain web requests with no real protection, so someone watching network traffic or poking at the app could fake or inflate scores. There's an admin panel protected by a password, but the scoring itself is fundamentally gameable. This makes it fine for prototypes, game jams, or casual projects where it doesn't matter if a determined player cheats, but not for anything competitive or production-ready. It's also worth noting the project hasn't seen much attention (four stars), so you'd be adopting a minimal tool rather than a maintained framework.
