IWSC 2025 (j) | Participants

Tabbycat is an open-source project developed by volunteers and is free to use. For a tournament of this size, we suggest a donation of $16. Learn more about donating.

Using an app designed for debate timekeeping makes speaking and adjudicating easier! Check out Timekept (iPhone/iPad) or Debatekeeper (Android).

Tabbycat is supported by the Tabbycat Debate Association, a non-profit for advancing open debate technology.
