RubyKaigi 2023 is an international Ruby conference that will take place in Matsumoto, Nagano, Japan from May 11th to 13th 2023, and we're looking for speakers!


  • RubyKaigi is a technical conference about Ruby and open source. Your topic should be exactly about or be strongly related to the Ruby programming language.

  • Taking a look at "Past Kaigis" (2022, 2021-takeout, 2020-takeout, 2020 (cancelled), 2019, 2018, 2017, 2016, 2015, 2014, 2013) that linked from should give you an idea of the taste of the Kaigi.

  • The time slot for your talk is planned to be 30 minutes.

  • Your talk can be given in either English (recommended) or Japanese. All Japanese talks will be simultaneously interpreted to English for the audience.

  • Speakers can either attend the in person conference and speak at the venue, or submit a pre-recorded video (please comment your preference with the proposal). Note that we're not planning to provide a scheme for realtime remote talk this year.

  • The CFP form will remain open until January 31st.

  • You need a GitHub and/or Twitter account to submit your proposal via this submission form.

  • We recommend you to submit your proposal early. The earlier you submit, the better the chance that your CFP will be reviewed and that you will get online feedback from the reviewers.
