Goals

• Libre software to host yourself, unlike Doodle
• More simple, sexy and/or fun than libre alternatives, in alphabetic order:
  • Bitpoll (ex. Dudel)
  • Dudle
  • (Drupal Date picker formatter)
  • (Foodle (discontinued; on GitHub, ex. DFN scheduler, ex. DFN Terminplaner+))
  • Framadata (Sources, ex. OpenSondage, ex. STUdS)
  • Noodle
  • Nuages
  • Pleft
  • Rallly
  • RDVz
• Keep things simple, usable, maintainable
• Support invocation from the command line, e.g. for spontaneous polls in a LAN
• Have security in mind

Please check out the list of upcoming features.

Non-goals

• Use of heavy frameworks: building blocks only
• Read availability from calendars
