I built Ellipticc Drive, an open-source cloud drive with true end-to-end encryption and post-quantum security, designed to be Dropbox-like in UX but with zero access to your data, even by the host.

What’s unique:

Free 10GB for every user, forever.

Open-source frontend (audit or self-host if you want)

Tech stack:

Frontend: Next.js

Crypto: WebCrypto (hashing) + Noble (core primitives)

Encryption: XChaCha20-Poly1305 (file chunks)

Key wrapping: Kyber (ML-KEM768)

Signing: Ed25519 + Dilithium2 (ML-DSA65)

Key derivation: Argon2id → Master Key → encrypts all keypairs & CEKs

Try it live: https://ellipticc.com

Frontend source: https://github.com/ellipticc/drive-frontend

Would love feedback from devs and security folks — particularly on encryption flow, architecture, or UX.

I’ll be around to answer every technical question in the comments!
