igProfiler is a simple and yet powerful tool to profile your code (in-game). YOU are the one making the decisions about what and when you want to profile. It works for both Unity Free and Unity Pro licenses.
*Very light and will not affect the performance of your game.
*Gives you a very easy and useful interface to measure every line of your code.
*Measure the performance of your code even outside the editor as the profiler runs on a in-game Unity GUI window.
*GUI is fully customizable.
*Full source code is provided so you can extend and change the tool to match the needs of you project and team.
*The code is very well commented and structured.
*There is a document that will give you a brief overview of the tool and a small tutorial so you can start profiling right away.
*You can start using the tool in just a few minutes as it requires almost no setup steps.
*The tool is extremely easy to use for people that are making their first steps into the world of game development.
Originally I developed the tool for myself to be able to profile and keep an eye for changes and spikes for a very performance demanding run-time terrain generation code that is part of the game I'm currently developing.
Any feedback when using the tool will be greatly appreciated and integrated ASAP.
