BlinkOn is the annual Chromium contributor summit. BlinkOn 21 runs April 20–21 this year, and for the first time ever, it will be hosted by Microsoft in Redmond, WA, instead of by Google in Silicon Valley. We’re proud to be long-time and leading contributors to Chromium’s codebase, so members of our Chromium and Web Platform teams will be at the summit, in person and remotely. Several are presenting, including:

• “Container Timing 2026 update” by José Dapena — where the Container Timing API stands now and what’s ahead.
• “History of the Web” (roundtable panel) — co-hosted by Brian Kardell and Patrick Brosset, with Mike Champion, Adrian Bateman, and Greg Whitworth.
• “Syncable a11y preferences in ChromeOS” by Antonio Gomes — a look at ongoing improvements to the state of syncing accessibility preferences across devices.
• “Bringing CTAP 2.2 hmac-secret-mc Support to Chromium” by Byungwoo Lee — adding the hmac-secret-mc extension from CTAP 2.2 to improve passkey credential handling in Chromium.
• “Progress of the tvOS port” by Gyuyoung Kim — a status update on Chromium for tvOS.
• “Progress of Extensions migration” by Miyoung Shin — where things stand in the move to modern extension APIs.
• “Mime Types Handler Liberation: Giving Extensions the Keys to the PDF Kingdom” by Maksim Sisov — making extensions first-class handlers for PDFs, rather than leaving it to the browser.

Talks will be recorded and published on the official BlinkOn YouTube channel after the event concludes.

We always look forward to talking with fellow Chromium contributors, and we hope to see you there!

Updated 20 April 2026 to add a talk that was accepted at the last minute.
