Sonda is a powerful and simple way to implement polls on a Website. It outputs a nice themed graphic table with a precise percentage calculation. It is easy to customize the way the program behave with a config file. There can be as many different and autonomous data and config files as are needed, and an infinite number of polls and options to vote on. The program locks the files it uses to avoid deadlocks and race conditions and keeps an IP log file of the people who vote. No database is necessary.
