Build products together at hackathons with agentic workflows
Hackathons are about speed and teamwork. YappJam puts your whole team in one agentic workspace — collaborate, preview instantly, and ship before the deadline.
Start a Hackathon RoomZero Setup, Maximum Speed
Create a room, share the link, and start building. No local dev environment needed. YappJam clones your repo, runs the dev server, and gives everyone a live preview. Your team goes from idea to working prototype in minutes, not hours.
Everyone Contributes
The designer connects Figma mockups so the agent sees the visual context. The backend developer shapes the API prompts. The PM defines requirements in natural language. Everyone's input steers the agentic workflow — that is the power of cross-functional collaboration.
See It Running as You Build
The built-in dev server starts automatically and updates in real time. Every team member sees the product running as the agent builds it. Catch issues immediately, iterate fast, and demo confidently when time is up.
