Vibe coding with Convex Chef: Winning Full-Stack Apps from the Convex Top Chef Hackathon
Right after Convex Chef dropped, devs jumped in the kitchen—competing for the Top Chef title in the Vibe Coding Hackathon. The mission: cook up a live app using Convex Chef and aim for one of three honors—Best Overall App, Best Use of AI, or Best Real-Time Experience.
Vibe coders were up for the challenge—starting fast with Convex Chef, then jumping into Cursor or their IDE to shape things by hand. That blend of AI and craft turned rough drafts into standout apps. A common vibe coding work flow. That blend of AI and craft became the secret sauce for this hackathon’s standouts.
Judging looked at creativity, execution, app quality, and how much buzz projects got across Reddit, Hackernews and LinkedIn. The winners didn’t just hit the goal—they went further and built apps that pulled people in.
Here they are—this season’s Top Chefs.
