The Photos "moments" grid rendered every tile into the DOM, so a 20k-photo library mounted ~140k nodes / 20k <img> elements, held ~196MB JS heap, took ~3.5s to first paint and scrolled at ~6fps. It also ran the justified-layout maths inside the template (recomputed on every reactive change) and generated client-side video thumbnails for every off-screen video, not just visible ones. Introduce `VirtualRows` — a variable-height, section-aware sibling of `VirtualList` — and flatten the grouped timeline into one list of fixed-height rows (a date header or a strip of explicitly-sized tiles) shared by both the square and justified layouts. Only the rows near the viewport are mounted; a prefix-sum offset table + binary search find the visible band, and a spacer reserves the full height so the sticky header and load-more sentinel are unchanged. The justified packing now runs once per groups/width/layout change in a $derived, not per render. To avoid duplicating the scroll-tracking logic across the two windowing components, extract it into a `useVirtualWindow` composable (scroll-ancestor detection + rAF-throttled aboveBy/viewportH signals); `VirtualList` is refactored onto it with identical measured numbers. Measured in headless Chromium (1280x900), synthetic photos, before/after: SQUARE | mount→tiles | DOM nodes | <img> | JS heap | scroll frame ------------+-------------+-----------+-------+---------+------------- 2000 | 416→94 ms | 14k→629 |2000→96| 21→5 MB | 29→29 ms 5000 | 916→114 ms | 35k→629 |5000→96| 50→9 MB | 62→26 ms 20000 | 3455→220 ms | 140k→629 |20k→96 |196→29 MB|152→33 ms JUSTIFIED 20000: mount 245 ms · DOM 315 · <img> 44 · heap 33 MB · ~60fps Rendered DOM, mounted <img> count and heap are now flat (O(visible)) regardless of library size; mount is ~16x faster and scroll jank drops from 413 to ≤24 frames. Off-screen video-thumbnail generation no longer fires for non-visible tiles. Correctness verified by probing a deep scroll in both layouts (tiles land within the viewport band; square cells equal-width, justified rows aspect-preserving).

A fast self-hosted cloud for people who want files, calendars, contacts, and office editing without dragging a heavy stack behind them.

If OxiCloud saves you setup time, RAM, or complexity, give it a star. If something is missing, ask for a feature or request a docs improvement.
Why People Try OxiCloud
OxiCloud is aimed at self-hosters, home labs, and small teams who want the useful parts of a cloud suite without the operational drag of a traditional PHP stack.
What pulls people in:
- Standard protocols first: WebDAV, CalDAV, and CardDAV are built in
- Useful product surface already there: files, previews, sharing, trash, search, favorites, and recent items
- Modern auth and admin basics: OIDC/SSO, quotas, roles, and shared links
- Better interoperability: native desktop and mobile clients work without custom sync tooling for basic access
- Lower deployment friction: Docker Compose, environment-based configuration, Helm chart, and Nix module
OxiCloud is not trying to mirror the full plugin ecosystem of Nextcloud. It is designed for a smaller stack, fast startup, and standards-based interoperability.
Quick Start
Docker Compose
Requires Docker and Docker Compose.
git clone https://github.com/AtalayaLabs/OxiCloud.git
cd OxiCloud
cp example.env .env
# If users will access OxiCloud through a domain or reverse proxy,
# set OXICLOUD_BASE_URL in .env before the first login.
docker compose up -d
Open http://localhost:8086.
Run from source
Requires Rust 1.93+ and PostgreSQL.
git clone https://github.com/AtalayaLabs/OxiCloud.git
cd OxiCloud
cp example.env .env
# If PostgreSQL runs on your host instead of Docker, update both
# OXICLOUD_DB_CONNECTION_STRING and DATABASE_URL to use localhost:5432.
cargo run

|---|---|
| Files via WebDAV | https://your-host/webdav/ |
| Calendars via CalDAV | https://your-host/caldav/ |
| Contacts via CardDAV | https://your-host/carddav/ |
Common clients that work well:
- macOS Finder

Help Shape OxiCloud
If you want OxiCloud to get better faster, use the repo like a product feedback loop, not just a code dump.
- Give it a star if you want more people to discover the project: Star OxiCloud
- Propose missing functionality: feature request
- Point out confusing onboarding or weak docs: documentation request
- Report breakage or regressions: bug report
- Build it with us: CONTRIBUTING.md
The best feature ideas usually come from real deployment pain. If you hit friction, open an issue and describe the workflow you want.
Architecture and Deployment
OxiCloud follows a clean, hexagonal architecture so protocol handlers, business logic, and infrastructure stay separated.
- Backend: Rust + Axum
- Database: PostgreSQL
- Configuration: environment variables
- Default deployment: Docker Compose
- Additional packaging: Helm chart and Nix module
Architecture docs: internal architecture · caching architecture · database transactions · storage safety
