Why Build with MentraOS?
- Cross-Compatibility: Build one app that runs on supported smart glasses from multiple manufacturers.
- Fast Development: Go from months of custom smart glasses development to a working app in days.
- Hardware Access: Use displays, microphones, cameras, speakers, and everything else smart glasses expose from one API.
- App Distribution: Publish to the Mentra MiniApp Store and reach users across the MentraOS ecosystem.
- Business Deployment: Deploy smart glasses apps for field work, remote support, training, accessibility, and compliance-sensitive workflows. MentraOS is already being deployed by Fortune 500 companies.
- Open Source Control: Own it, host it, modify it, and extend it. MentraOS is Apache-2.0-licensed infrastructure designed for privacy, transparency, and freedom from hardware or cloud lock-in.
Apps on the Mentra MiniApp Store
Browse, install, and run glasses apps from your phone. Try captions, AI notes, proactive AI, translation, streaming, and more.
How MentraOS Works
MentraOS runs glasses apps on the phone inside the Mentra Runtime. Multiple glasses apps can run simultaneously, controlling your smart glasses through one shared connection.
This keeps the glasses lightweight while letting multiple apps run together, like captions, notes, notifications, dashboard, and AI tools. It also allows one app to work with any pair of supported smart glasses.
Manufacturers can integrate the Mentra Runtime into their own iOS and Android apps to unlock the Mentra ecosystem while preserving their brand, app, and customer relationship.
Nightly Builds
MentraOS is built by developers, companies, and users who believe the next personal computer should be open, cross-compatible, private, and user-controlled.
