## A fast, simple alternative to NextCloud
<br/>
NextCloud was too slow on my home server. So I built OxiCloud: a file storage system written in Rust that runs on minimal hardware and stays out of your way.
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 Dashboard](doc/images/Captura%20de%20pantalla%202025-03-23%20230739.png)
## Why OxiCloud?
<!-- TODO: add animated GIF/demo here -->
| Feature | What you get |
|---------|--------------|
| **Low resources** | Runs on 512MB RAM. No PHP, no bloat. |
| **Fast** | Rust with LTO optimization. Sub-second responses. |
| **Clean UI** | Works on desktop and mobile. No clutter. |
| **Easy setup** | One binary, one database, done. |
| **Multi-language** | English, Spanish and Persian out of the box. |
---
## 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
- **112 automated tests** — `cargo test` on every push (CI)
- **9 languages** — EN, ES, DE, FR, IT, PT, NL, ZH, FA
---
## Quick Start
You need Rust 1.70+, Cargo, and PostgreSQL 13+.
### Docker (recommended)
```bash
git clone https://github.com/DioCrafts/oxicloud.git
cd oxicloud
# Set up your database connection
echo "DATABASE_URL=postgres://username:password@localhost/oxicloud" > .env
# Build and run
cargo build --release
cargo run --bin migrate --features migrations
cargo run --release
```
Open `http://localhost:8086` in your browser.
### Docker (alternative)
```bash
# Copy example environment file and customize
# Copy and optionally edit environment
cp example.env .env
# Edit .env with your settings (optional - defaults work for quick testing)
docker compose up -d
```
That's it. The app runs on port 8086.
Open **http://localhost:8086**. That's it.
### 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
# Run migrations and start
cargo run --bin migrate --features migrations
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) |

## Architecture
OxiCloud uses Clean Architecture with four layers:
Clean / Hexagonal architecture — each layer depends only on the one below:
```
┌─────────────────────────────────────────┐
│ Interfaces │ API routes, handlers │
├─────────────────────────────────────────┤
│ Application │ Use cases, services │
├─────────────────────────────────────────┤
│ Domain │ Business logic │
├─────────────────────────────────────────┤
│ Infrastructure│ Database, filesystem │
└─────────────────────────────────────────┘
┌───────────────────────────────────────────────────────────────┐
│ Interfaces │ REST API, WebDAV, CalDAV, CardDAV, WOPI │
├───────────────────────────────────────────────────────────────┤
│ Application │ Use cases, DTOs, port definitions │
├───────────────────────────────────────────────────────────────┤
│ Domain │ Entities, business rules, repository traits │
├───────────────────────────────────────────────────────────────┤
│ Infrastructure│ PostgreSQL, filesystem, caching, auth │
└───────────────────────────────────────────────────────────────┘
```
Each layer only talks to the one below it. You can swap out the database or add new API endpoints without touching business logic.
Swap the database, add a new protocol, or change auth — without touching business logic.
