Plan your conference week in Las Vegas without the spreadsheet chaos. SessionStack is a session planner for attendees of AWS re:Invent 2026. Browse 2,200+ sessions across six venues on the Strip. Ask in one sentence and the AI turns it into filters you can see. Leave an afternoon open and it suggests sessions that are worth your time and that you can actually reach. And it will never book you two talks twenty minutes apart at opposite ends of the Strip. SessionStack is an independent app made by attendees, for attendees. It is not affiliated with, endorsed or sponsored by Amazon Web Services, Inc. or its affiliates. AWS and re:Invent are trademarks of Amazon.com, Inc. or its affiliates.
