Could you build this?
Partial While client-side Web Crypto API encryption and basic pastebin features are vibe-codeable, building a secure, multi-tenant sandbox for arbitrary live code execution alongside E2EE device synchronization is complex systems work.
What it would actually take: The architecture requires a frontend with Web Crypto APIs for AES-GCM client-side encryption, a lightweight backend, and an isolated remote code execution engine (e.g., gVisor, Firecracker microVMs, or Docker sandboxes with strict seccomp filters and network isolation). The hard parts are securely isolating arbitrary code execution against escape vulnerabilities and implementing cryptographically sound device-pairing protocols via QR codes.
