Runtime protection for React Native and Expo apps
Rampart is an open-source, Apache-2.0 toolkit that detects rooted and jailbroken devices, hooking, tampering, emulators, clones, screen capture, overlays and more — without sending a single byte off the device.
Clean-room
Built only from public platform docs, OWASP MASTG/MASVS and open research. No proprietary SDK code, ever.
Zero network
The library makes no network calls and ships no telemetry. Your users’ device data stays on the device.
Report and react
Rampart reports threats to your code. It never kills the app; you decide what happens next.
Server-anchored
Pairs on-device signals with Play Integrity and App Attest verified on your backend.
