The partlister is an Open-Source Ruby on Rails application designed to help manage a electronic inventory.

Created as a weekend project, the application uses Twitter Bootstrap for its front-end design and the Rails framework for its backend.

Initially created for managing the component inventory at the Centre for Electronic Design and Technology, NSIT Lab, the application is now open-sourced.
