The Psychology Experiment Building Language (PEBL) is a free cross-platform system for designing and running computer-based experiments and tests. It is free to use, free to change, and free to give to others. You will always have access to the software you used to collect your data, because there are no licenses to maintain, and you can give your experiments to others and they will be able to use them, even without buying a license.
PEBL experiments are creating with a special-purpose programming language designed to focus on the critical aspects of creating experiments. These include easily creating displays (graphics, shapes, text, etc.), collecting responses (mouse and keyboard), experimental design (randomization and counterbalancing), and data recording.
 PEBL Test Battery
PEBL distributes a set of approximately 50 standard and novel test in the form of the PEBL Test Battery. Many of these tests are the only free version of commonly-used tests that otherwise cost hundreds of dollars.
