Build the future with Vercel + Meta, supported by Neon.
FAST FORWARD challenges builders to create AI apps and agents that keep working, adapt intelligently, and help people understand, decide, and act faster. Join Vercel and Meta, with integration partner Neon Postgres, for an in-person hackathon on Wednesday, October 14, 2026, from 10am–6pm Pacific at Motoring Coffee in San Francisco. Choose one track: Agents & Factories, Multi-modal Apps, or VR Apps. Build with mentor support, demo your project, and compete for one winning team per track. Teams may include up to four people. Registration and host approval are required through https://luma.com/fastforwardhack.

For this hackathon, I’m building PeekaPlate around a simple idea: ordering food from home can feel more personal, more visual, and easier to navigate. An agent to guide you. A meal you can explore before you choose. PeekaPlate. Your next meal, brought into view.
Shake it! Mushroom is a cozy WebXR mushroom-foraging RPG for Meta Quest. You shrink into a glowing acorn village and pick living mushrooms with your bare hands: grab the stem, wiggle it to loosen the roots, then pull. Haptics, soil crunches and a juicy pop sell the feel, and every species feels different (puffballs pop easily, fly agarics are stubborn). Your guide is Jev, a firefly companion powered by TypeSafe's Jev System One model through Vercel AI Gateway. About four times per second it reads the live game state (your hand, root looseness, quest, idle time) and decides in ~200-400 ms when to speak, which line fits, its mood, and which mushroom to fly to. Its decisions are shown in a small companion card (desktop) or on your left wrist (VR) without blocking play. Follow Jev's "PULL NOW!" call for a PERFECT pull and bonus coins. RPG loop: Grandma's quest, a collectible codex with rare variants, harvest grades, coins, and a Thorn Stick reward. Finishing the quest lifts the fog and opens the Grass Sea, a giant meadow with more mushrooms and a dandelion tower to explore. Built with Meta IWSDK + Three.js (WebXR, hand tracking with controller fallback, free locomotion with snap turn and teleport), TypeSafe Jev via Vercel AI Gateway in a Vercel serverless function, Tripo-generated 3D assets, WebAudio procedural SFX, deployed on Vercel.
VibeCheck is a mixed-reality dance and fitness coach built for Meta Quest 3. After the pandemic and the explosion of TikTok dances, a lot of people learn dance moves from online videos. A video shows you the move and a mirror shows you yourself, but neither tells you what you're doing wrong. With VibeCheck, you stand in front of a real mirror wearing the Quest and the headset's passthrough camera watches your reflection. VibeCheck estimates your posture on top of it, each limb is colored and labelled by how closely it matches the reference, with a ghost of the instructor's pose fitted to your body. The reference video plays beside the mirror and a voice coach gives you specific corrections. At the end of a routine, you get a report card showing your grade, with a per-limb breakdown and tips. Technologies: Meta Immersive Web SDK (WebXR immersive-ar with passthrough and hand tracking), the Quest passthrough camera through getUserMedia, MediaPipe Pose in the browser, Next.js on Vercel, Vercel Blob for videos and pose timelines, and the AI SDK through Vercel AI Gateway with fallback models: Llama 4 Scout writes the coach lines, Llama 4 Maverick writes the report card, OpenAI TTS speaks them. How it meets the VR Apps criteria: Mirror Coach is an immersive WebXR mixed-reality session that runs in Quest Browser from a live Vercel HTTPS URL, with nothing to install. We tested it end to end on a real Quest 3 in front of a mirror.
CASH is a shell that a team and its agents share. Sign in with a username, enter a room, open a task. On the left, the conversation: people and agents steer in the same stream, with commands like /agent, /approve, /pull and /status. On the right, the agent at work: a code file, a document, an image or a scheduled pipeline, with a viewer that adapts to the task type. Everyone sees the same state live from Neon Postgres. Each person gets a background assistant that reads what others did, explains it, and proposes the next action; reading needs no permission, acting does, so you approve with one click. Context is unified: /pull brings another task's artifact and discussion into the one you are in. Shell tasks are Unix-style agent pipelines (small commands joined by pipes) that keep running on a schedule after you walk away. This is how Xyne, Juspay's open-source org OS, thinks about agents: shared context, permission-aware, people and agents in one place.
Desktop Destroyer, but it's your real house. Quest passthrough + scene understanding turn your real walls, table, couch and windows into things you destroy with bare hands. Palm tool wheel (sledgehammer, chainsaw, flamethrower, machine gun, paint, flour bomb, fire ants, wasps, camel crickets), throw chairs through windows, raid the fridge, AI Gateway vision identifies unknown objects, DAMAGE $ ends in an insurance receipt. Built by the COGGS agent game harness in one 20-minute autonomous run.
Watching Formula 1 is hard. TV shows you whatever shot the director picks, and a grandstand seat gives you one car every 90 seconds. F1's latest fix is FPV drones that chase the cars at 300 km/h, but a drone is still someone else's camera. Trackside is a WebXR app for F1 fans that puts you inside the race. You can watch the real 2026 British Grand Prix from onboard any of the 22 cars, rebuilt from OpenF1 position, telemetry and team radio data. Or you can take the wheel and race the real field yourself. While you drive, an AI race engineer powered by Meta's Muse Spark talks to you over team radio, just like in a real F1 race. It calls out your braking and apexes against Antonelli's actual fastest lap, and it answers when you talk back.
Review the rules, tracks, and submission requirements in one place.
