SensAI: Worlds in
Action Hackathon.
Visit the SensAI LA hackathon websiteWelcome, SensAI hackers. This page collects everything you need to ship an AR project in a weekend with React Native and ViroReact: an MCP server for your coding agent, a ready-to-run starter kit, a geospatial AR example, and a free Studio account. The ReactVision team is on Discord all weekend if you get stuck.
Get started with ReactVision
Our introduction to ReactVision from the hackathon's online sessions. In it we cover what you can build with React Native and ViroReact, and specifically our AI tools for the weekend: the ViroReact MCP server for your coding agent and AI asset creation in Studio. The video starts right where our session begins.
Your hackathon toolkit
Four things to set up before you start building. Together they take about fifteen minutes and cover the whole stack: an account for the platform, knowledge for your coding agent, a project to build on, and a worked example to learn from.
Create a free Studio account
Your Studio account unlocks the ReactVision Platform: it authenticates the MCP server and powers geospatial anchors, Cloud Anchors, and AI asset creation. It is free and takes a minute, so make this your first stop.
ViroReact MCP Server
Plug current, accurate ViroReact knowledge straight into Claude, Cursor, Codex, or any coding agent that speaks MCP. Your agent gets the full component catalogue, working examples, and scene validation, so the AR code it writes runs the first time.
Starter Kit
An Expo + TypeScript project with working AR demos ready to run on your device. Scenes, 3D objects, interaction, plane detection, and shaders are all wired up, so it is the fastest way from zero to AR on a phone.
Geospatial AR example
A worked example of anchoring AR content to real-world coordinates, built with Claude Code and ViroReact. Follow the step-by-step tutorial or jump straight into the finished project on GitHub.
Free Pro tier for the hackathon
Everyone building with ReactVision at the hackathon gets the Studio Pro tier free for a month, so you have maximum capacity for the weekend. Once you have created your account, it takes three steps:
Create your Studio account
If you have not already, create a free Studio account. It is free and takes a minute.
Upgrade on the monthly plan
In Studio, open your team's Billing section and upgrade to the Pro tier on the monthly plan. Make sure it is monthly, not annual.
Apply the discount code
Apply the code SENSAI2026 at checkout and the Pro tier is free for a month.
Real-world apps built with ReactVision, used by thousands
The stack you are building on this weekend already powers shipped products. Pikd landed Red Bull and Burger King with location-based AR played by over ten thousand users, and Looking Glass anchors Pittsburgh's erased Black history to the streets where it happened. Both shipped from a single React Native codebase.
Pittsburgh's erased Black history, back on the streets in AR
Adrian Jones built Looking Glass, a place-based AR storytelling app, with ViroReact and Studio. No game engine, open-source tools, and full control over the data.
Location-based AR that landed Red Bull and Burger King
Toch Emuwa's team built Pikd, a gamified AR platform for brand engagement, on ViroReact, shipping to iOS and Android from one codebase to land 30+ brands.
Stuck? We're on Discord.
The ReactVision team is in our Discord server throughout the hackathon, and we also have a dedicated ReactVision channel on the SensAI Hackademy Discord. Ask anything, from setup problems to AR design questions, and share what you're building.
More events during SIGGRAPH week
The hackathon is one of many side events around SIGGRAPH 2026 in Los Angeles. Here is what else is on during the week, from technical conferences to mixers and parties.
