CFP Description

Who are we looking for?

We welcome all types of speakers - experienced and first-timers. If you have something cool to say, we want to hear from you! We also believe diversity of speakers makes our event better, we welcome speakers of any gender, sexual orientation, disability, physical appearance, race, or religion.

What types of sessions do we accept?

  • Talk (30min): general WebAssembly-related talk
  • Workshop (2h): hands-on labs with a small group
  • Panel (30min): thematic session with 3-4 panelists and led by a moderator (you can propose a full panel with panelists and moderator or propose to be a panelist for a given topic)

If you have a co-presenter, you must first create the session in the “My Talks” section, invite your co-presenter, and then submit the session to the CFP.

What is the deadline to submit a proposal?

The CFP deadline is Wednesday 24th December 2025. If you have any questions or concerns, please reach out to the Wasm I/O team at info@wasm.io. We’re happy to help with anything you need.
