What is Flawfinder?
Flawfinder examines source code and reports possible security weaknesses (``flaws'') sorted by risk level. It's very useful for quickly finding and removing at least some potential security problems before a program is widely released to the public. Flawfinder works on Unix-like systems today (it's been tested on GNU/Linux), and it should be easy to port to Windows systems. It requires Python 1.5 or greater to run (Python 1.3 or earlier won't work).

Is actively maintained and really fast. Works out of the box without configuration.
