Cloud storage decision
MEGA Pro I
A single developer can build a minimal zero-knowledge file store (uploads, client-side encryption, links) but reproducing MEGA's global scale, multi-platform apps, bundled VPN/password-manager products and production-grade infra is not realistic for a small DIY effort.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Allow a user to upload a file from a browser, encrypt it client-side, store the encrypted blob in object storage, persist searchable metadata on a server, and let the user generate a shareable link that others can use to download and decrypt the file.
What it still won’t have
- MEGA multi-platform desktop and mobile apps
- Bundled VPN and password-manager products
- Global scalable object storage and large-scale infrastructure
- Polished sync clients, real-time collaboration and meeting features
What remains hard
- Infrastructure at scale
Object storage Fully scalable S3 compatible storage
- Brand trust

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal zero-knowledge cloud storage web app using React for the frontend, Node.js (Express) for the backend, Postgres for metadata, and an S3-compatible object store for blobs. In scope: client-side encryption/decryption (WebCrypto), streaming uploads/downloads of encrypted blobs to S3, metadata CRUD in Postgres, user auth (email + password), shareable links with optional password and expiry, and a simple React UI to upload, list, generate links, and download. Out of scope: mobile/desktop native apps, VPN, password manager, advanced sync clients, multi-region replication, enterprise billing. Include unit and integration tests for crypto, upload/download, and link expiry paths; log and surface clear error messages for failed uploads, decryption errors, and expired links.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
