TPAC 2025 Breakouts recap
Breakout sessions are one of the most popular activities during TPAC. Participants organize discussions about urgent, exciting and important topics related to Web technology, W3C and the future of the Web.
As part of TPAC 2025, participants proposed and ran 85 breakout sessions for the more than 500 participants on site in Kobe, Japan, and nearly 200 remote participants.

Each issue in the GitHub repo describes a session and includes (where known) links to agendas, slides, minutes, and any recorded presentations. We’ve asked each session organizer to communicate where they expect discussion to continue.
As in previous years, attendees have provided positive feedback on the sessions themselves and how we organized the agenda. This year for the first time we scheduled breakouts on multiple days, which reduced the number of parallel sessions in a given time slot (and thus reduced frustration when people wanted to attend “competing” sessions).
All in all, there were 9 sessions with a maximum of 10 rooms in parallel this year, to be compared with 6 sessions with a maximum of 14 rooms in parallel in 2024, for the same number of sessions (85 in both cases).
This seems to have helped because we’ve heard more expressions of satisfaction and fewer laments. Given the feedback, we have already started thinking about how to add more breakouts next year on more days to further reduce the number of sessions at the same time.
As a reminder, anyone may attend TPAC breakout sessions remotely at no cost, so please join us for TPAC 2026 breakouts next year in October 2026.
