GhostBuster

Built at Zero to Agent: Vercel x Deepmind Hackathon NYC · Mar 21, 2026 · New York, NY

GhostBuster — Demo video

GhostBuster Demo lets any product team point the browser extension at a broken UI, narrate what’s wrong, and immediately see the issue become a tracked GitHub ticket that an in-house “ghostbuster” agent fixes in a safe Supabase-backed sandbox before redeploying to Vercel. That means customer-facing bugs turn into annotated timelines, complete with screenshots, DOM snapshots, and transcripts, so PMs, QA, and engineers watch “report → triage → code fix → redeploy” without leaving the dashboard, radically shrinking time-to-resolution while keeping an auditable history for compliance and customer trust. Technical Snapshot: A Chrome extension records the screen, DOM, and voice, uploads everything to a Next.js + Vercel AI SDK route that calls Gemini 2.5 Flash via generateObject to emit a Zod-typed JSON bug report; that report becomes both a GitHub issue and the input to an autonomous tool-calling loop that reads/writes the Supabase-hosted codebase, runs fixes in a Supabase-powered sandbox, streams deployment status through Vercel’s APIs, and surfaces the whole timeline in a Clerk-secured React interface with Supabase Realtime updates.
