NextCloud was too slow on my home server. So I built OxiCloud — a complete cloud platform written in Rust that runs on minimal hardware and stays out of your way.

## OxiCloud vs NextCloud

| Metric | OxiCloud | NextCloud |
|--------|----------|-----------|
| **Language** | Rust (compiled, zero-cost abstractions) | PHP (interpreted) |
| **Docker image** | ~40 MB (Alpine, static binary) | ~1 GB+ (Apache + PHP + modules) |
| **Idle RAM** | ~30–50 MB | ~250–512 MB |
| **Cold start** | < 1 s | 5–15 s |
| **CPU at idle** | ~0 % | 1–5 % (cron, background jobs) |
| **Min. hardware** | 1 vCPU / 512 MB RAM | 2 vCPU / 2 GB RAM (recommended) |
| **Concurrent uploads** | Parallel chunked (TUS-like), async I/O | Sequential PHP workers |
| **File dedup** | SHA-256 content-addressable, ref-counting | None (each user = full copy) |
| **DB connections** | Dual pool (user + maintenance) | Single pool, background jobs compete |
| **LTO + PGO** | Fat LTO, codegen-units=1, opt-level=3 | N/A (interpreted) |
| **Dependencies** | Single binary + PostgreSQL | PHP, Apache/Nginx, Redis, Cron, …  |
| **WebDAV** | Built-in (RFC 4918, PROPFIND streaming) | Built-in |
| **CalDAV / CardDAV** | Built-in | Via apps |
| **WOPI (Office editing)** | Built-in (Collabora / OnlyOffice) | Via apps |
| **OIDC / SSO** | Built-in (Keycloak, Authentik, …) | Via apps |

> **Note:** NextCloud is a mature, feature-rich ecosystem. OxiCloud targets users who prioritise raw performance, simplicity, and low resource usage over plugin breadth.

## Features

### Storage & Files
- **Upload / download / organise** — drag-and-drop, multi-file, grid & list views
- **Chunked uploads** — TUS-like protocol, parallel chunks, resumable, MD5 integrity
- **File deduplication** — SHA-256 content-addressable blobs with automatic ref-counting
- **Adaptive compression** — zstd / gzip selected per MIME type
- **Trash bin** — soft-delete, restore, auto-purge by retention policy
- **Favourites & recent files**
- **Full-text search** — by name, type, date range, size, recursive subtree (ltree)
- **MIME magic-byte detection** — `infer` crate, not just extension guessing
- **Inline preview** — images, PDF, text, audio & video player modal
- **Thumbnails & transcoding** — WebP / AVIF on-the-fly via `image` crate

### Protocols
- **WebDAV** — RFC 4918, streaming PROPFIND, locking, compatible with all major clients
- **CalDAV** — calendar sync (Thunderbird, GNOME Calendar, iOS, DAVx⁵, …)
- **CardDAV** — contacts sync with vCard support
- **WOPI** — edit Office docs in Collabora Online or OnlyOffice
- **REST API** — complete JSON API for all operations

### Security & Auth
- **JWT authentication** with refresh tokens
- **Argon2id** password hashing
- **OIDC / SSO** — Keycloak, Authentik, Authelia, Google, Azure AD…
- **Role-based access** — admin / user, per-folder permissions
- **Storage quotas** per user
- **Shared links** with optional password protection

### Infrastructure
- **Single binary** — no runtime, no interpreter, no framework overhead
- **~40 MB Docker image** (Alpine)
- **Dual DB pool** — dedicated maintenance pool so background tasks never starve user queries
- **LTO-optimised release** — fat LTO, 1 codegen-unit, `opt-level = 3`, stripped
- **Write-behind caching** (moka) — sub-millisecond hot reads
- **222+ automated tests** — `cargo test` on every push (CI)
- **14 languages** — EN, ES, DE, FR, IT, PT, NL, ZH, JA, KO, AR, HI, FA, RU

## Feature Status

| Feature | Status | Notes |
|---------|--------|-------|
| **File storage & upload** | ✅ Working | Chunked uploads, deduplication, thumbnails |
| **WebDAV** | ✅ Working | Fully compatible with major clients |
| **CalDAV (Thunderbird, iOS)** | ✅ Working | Calendar sync functional |
| **CardDAV (Thunderbird, iOS)** | ✅ Working | Contacts sync functional |
| **DAVx⁵ (Android)** | ⚠️ Partial | File sync works; calendar/contacts in progress |
| **WOPI / Office editing** | ✅ Working | Collabora/OnlyOffice integration |
| **OIDC / SSO** | ✅ Working | Keycloak, Authentik, Google, Azure AD |
| **Trash / recycle bin** | ✅ Working | Soft-delete with restore |
| **Full-text search** | ✅ Working | Recursive subtree search |
| **Shared links** | ✅ Working | Optional password protection |
| **Music library & playlists** | ✅ Working | Streaming player, drag-and-drop reorder |
| **Photo gallery** | ✅ Working | Day/month/year views, multi-select |
| **Desktop sync client** | ❌ Planned | Not yet available |
| **Android / iOS app** | ❌ Planned | Not yet available |
| **End-to-end encryption** | ❌ Planned | Roadmap item |

> **Note:** The DAVx⁵ Android app currently works for file sync via WebDAV, but calendar and contacts sync via CalDAV/CardDAV is still being refined. Use Thunderbird or iOS native clients for full CalDAV/CardDAV support.

## Quick Start

### Docker (recommended)

```bash
git clone https://github.com/DioCrafts/oxicloud.git
cd oxicloud

# Copy and optionally edit environment
cp example.env .env

docker compose up -d
```

Open **http://localhost:8086**. That's it.

If you want to access the server remotely set the OXICLOUD_BASE_URL to your server's domain/port or the authentication will fail after setting up the admin user.

### From source

Requires **Rust 1.93+** and **PostgreSQL 13+**.

```bash
git clone https://github.com/DioCrafts/oxicloud.git
cd oxicloud

# Configure database
echo "DATABASE_URL=postgres://user:pass@localhost/oxicloud" > .env

# Build optimised binary
cargo build --release

# Start the server (migrations run automatically)
cargo run --release
```

---

## Client Setup

OxiCloud speaks standard protocols — any WebDAV / CalDAV / CardDAV client works:

| Client | Protocol | URL |
|--------|----------|-----|
| Windows Explorer | WebDAV | `http://host:8086/webdav/` |
| macOS Finder | WebDAV | `http://host:8086/webdav/` |
| Nautilus / Dolphin | WebDAV | `dav://host:8086/webdav/` |
| Thunderbird (calendar) | CalDAV | `http://host:8086/caldav/` |
| Thunderbird (contacts) | CardDAV | `http://host:8086/carddav/` |
| DAVx⁵ (Android) | CalDAV + CardDAV | `http://host:8086/` |
| GNOME Calendar | CalDAV | `http://host:8086/caldav/` |
| GNOME Contacts | CardDAV | `http://host:8086/carddav/` |
| Collabora / OnlyOffice | WOPI | See [WOPI docs](doc/wopi-integration.md) |

For detailed setup guides: [WebDAV](doc/webdav-integration-guide.md) · [CalDAV](doc/caldav-technical-spec.md) · [CardDAV](doc/carddav-technical-spec.md) · [OIDC/SSO](doc/oidc-integration.md)

## Architecture

Clean / Hexagonal architecture — each layer depends only on the one below:

```
┌───────────────────────────────────────────────────────────────┐
│  Interfaces    │ REST API, WebDAV, CalDAV, CardDAV, WOPI      │
├───────────────────────────────────────────────────────────────┤
│  Application   │ Use cases, DTOs, port definitions            │
├───────────────────────────────────────────────────────────────┤
│  Domain        │ Entities, business rules, repository traits  │
├───────────────────────────────────────────────────────────────┤
│  Infrastructure│ PostgreSQL, filesystem, caching, auth        │
└───────────────────────────────────────────────────────────────┘
```

Swap the database, add a new protocol, or change auth — without touching business logic.
