Welcome to Hydrangea Hacks! Hydrangea Hacks is a virtual hackathon for women and non-binary individuals on June 18-20. The hackathon aims to cultivate and foster diversity in tech among young beginners and professionals. You may build or design whatever you like though participants may create and submit a project to a track of their choice! All you need is a computer, and if you want, a few friends to hack with!

  • Identify as women or non-binary
  • Be at least 13 years old
