About OpenBehavior

Launched in 2016, the OpenBehavior Project provides a centralized repository of tools for animal behavior research. Our goal is to empower your research, so you can use the latest tools as quickly as possible.

What is Open Source?

  • Open Access

  • Open-source projects share their files and code freely. Anyone can view, modify, and improve them.
  • Collaborative

  • Be part of a community of researchers working together to innovate and problem-solve.
  • Cost-Effective

  • Use existing tools at a fraction of the price of commercial products.
  • Customizable

  • Build and modify tools to perfectly fit your specific research needs.
You can read more about OpenBehavior’s approach in our 2019 paper featured in eNeuro.
