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

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?
