FileFreak.io

Cloud storage, rebuilt as a developer platform.

filefreak.io SDK on npm API reference

Private repository

Overview

A cloud drive that grew into a platform: files, static sites, git repositories, npm packages and container images under one account and one usage-based bill. It ships with a Rust CLI, a desktop client, a TypeScript SDK and a documented API. The developer tools are in beta, and this site is one of the sites it hosts.

How it's built.

File bytes never touch the API
The API signs short-lived addresses and the browser or CLI talks to storage directly, with resumable multipart uploads. The folder tree lives in Postgres, so a move or a rename is a single update.
Sends only what changed
Content-defined chunking (FastCDC), shared by the Rust CLI and the TypeScript SDK: a new version of a large file uploads only the blocks that changed.
Shard Protection
A protected file is cut into fragments, each encrypted on the client with AES-256-GCM under its own key and spread across separate storage accounts. The format is published, versioned and pinned by byte-for-byte test vectors.
Speaks the real protocols
A private npm registry, an OCI container registry that passes the official conformance suite, and git over HTTPS with Git LFS. Each is acceptance-tested with the real npm, Docker and git clients.
Sites at the edge
Static hosting on a Cloudflare Worker: custom domains, deploys that upload only changed files, rollback across the last ten deploys, and cookieless analytics added at the edge.
One platform, every surface
A Rust CLI with two-way folder sync tested over thousands of seeded random histories, a Tauri desktop client that reuses the website's own React components, and a typed SDK on npm.
