Build a real AR/VR app with React Native - no Unity, no native rewrite, just the stack you already know. ReactVision and Expo are teaming up for a hackathon built for developers who want to go past the demo stage. One fixed build week, four cities, real judges, and a direct path into Expo's App Awards if you ship something worth entering. We're looking for real AR/VR depth: geospatial anchoring, cross-platform native builds, spatial experiences that actually work in the physical world. Bring an idea, bring a team (or fly solo), and build something that runs on iOS, Android, and Quest from one codebase.
🎮 Details. Who can participate: All skill levels welcome · Individuals & teams (up to 4). Open globally, in-person events in SF, London, Bengaluru and Toronto. 📅 Build Week: Oct 3–11, 2026. 📍 Format: Global, virtual build week + in-person regional finals. 🏆 4 prize tiers · Guaranteed perks for all participants.
Ctrl+Space is a joint hackathon between ReactVision and Expo, focused on building real AR/VR experiences using React Native: no Unity, no native rewrites, no starting from scratch. This hackathon invites developers, designers, and builders to create next-generation spatial computing experiences across industries like education, real estate, retail, training, and enterprise.
✨ What Makes Ctrl+Space Special. 🌐 Focus on real spatial computing: geospatial anchors, cloud anchors, and genuine device-agnostic builds, not surface-level AR effects. 🧠 Build with code (ViroReact + MCP server) or no-code (ReactVision Studio): pick the path that fits you. 🤝 Open for both solo participants and teams. 🚀 Direct eligibility for Expo's App Awards if you ship something real.
🛠 What You Can Build. You can create: AR/VR experiences using ViroReact, ReactVision Studio, or the MCP server. Geospatial or Cloud Anchor–based experiences: persistent, real-world-anchored, not single-session. Cross-platform builds: one codebase shipping to phone and Wearables alike. Spatial training, education, or simulation experiences. Agent-built apps: use an AI coding agent connected to the ViroReact MCP server to scaffold and validate your scene. Infrastructure or tooling that uses Expo's build/deploy stack alongside ReactVision.
🎯 Important Creation Guidelines. To ensure quality and consistency across submissions: Build your AR/VR experience using ViroReact, Studio, or the MCP server. For education or training use cases: include a clear walkthrough (voiceover or on-screen explanation) so judges understand the concept. For other use cases (retail, real estate, enterprise, etc.): show the experience running and interacting in a real environment, not just a static render.
⚠️ Important Note. 🚫 Submissions without a demo video will NOT be considered. Also share on social media and tag @reactvision and #Ctrl+Space.
Requirements 📦 Submission Requirements. To submit a valid project, include: 🔹 Basic Details — Project Title & Description, Problem Statement, Solution Overview, Target Users / Industry. 🎥 Demo Video (Mandatory – 2–4 mins) — Your video must clearly explain: What you built, How it works, Why it matters. 🖼 Additional Assets — Screenshots / Images (at least 2), Tech Stack Used, GitHub / Source Code Link, Platform Details (iOS, Android, Meta Quest, or Web).

Judging Criteria. Innovation & Creativity: Originality of the idea and uniqueness of approach to the problem space. Technical Implementation: Effective, skillful use of ViroReact, Studio, geospatial/cloud anchors, or the MCP server. Real-World Impact: Applicability to a real industry or use case: not just a technical demo. Design & Experience: Immersion quality, usability, and how the interaction actually feels. Presentation & Demo Quality: Is the demo video clear, concise, and does it actually prove the thing works?
