Self-hosted cloud storage that doesn't feel like 2012.

A lightweight, compiled alternative to Nextcloud Enterprise. Built with Swift and Vapor to deliver high performance on everything from a Raspberry Pi to enterprise servers.

Simply beautiful. Entirely native.

FynnCloud integrates directly with your operating system, behaving like a native system service. Access your files instantly in Finder, sync changes in real-time, and share folders without the bloat of traditional web interfaces.

Native macOS integration.

Integrated directly into Finder. Access all your files on-demand without consuming local storage space.

Native sharing.

Share files and folders directly from the Finder context menu. Create secure links, enforce passwords, and set expiration dates.

Snappy web dashboard.

A responsive, modern web interface. Preview documents, manage storage, and invite team members with zero page reloads.

Real-time delta sync.

Sync only changed files and structural updates via a sequence-based delta timeline. Save bandwidth and sync updates instantly without scanning whole directories.

Engineered for speed.

FynnCloud launches instantly, handles heavy synchronization tasks concurrently, and maintains a microscopic system footprint. Performance is built into the compiler.

Powered by Swift.

Compiled directly to native machine code. FynnCloud utilizes Swift's modern concurrency to handle thousands of requests with sub-millisecond latency.

AI semantic search.

Find files, PDFs, and images by meaning rather than filename. Auto-OCR extracts text to feed a multi-modal vector search index.

Single-binary deployment.

No Apache, no PHP-FPM pools, and no complex configuration files. Run the backend as a single statically-linked binary.

Zero-copy streaming.

Stream multi-gigabyte uploads directly to your storage backend without buffering files in memory, keeping your server stable.

Modern security.

Features enterprise-ready user authentication, token-based API security, and seamless user directory integrations.

S3-compatible.

Store files on local disks or offload them to any S3-compatible cloud storage provider with a simple configuration.

Asynchronous job queues.

Offload intensive tasks like thumbnail generation and OCR text extraction to background Redis worker queues to keep API latency sub-millisecond.

See how it stacks up.

Verified by real-world side-by-side performance benchmarks running on a modest Raspberry Pi 5.

Sync Request Latency (TTFB)

FynnCloud (Swift + Vapor) 12 ms

Nextcloud Enterprise (PHP + Apache) 240 ms

Response latency for a delta sync request -95%

Server Memory Footprint (Idle)

FynnCloud 42 MB

Nextcloud Enterprise (Apache + FPM pool) 626 MB

Memory consumption of idle backend services -93%

Fair. Scalable. Transparent.

We explicitly target the ignored 10-to-99-user segment with zero seat minimums, alongside a highly permissive free tier for homelabs.

Business Source License (BSL 1.1)

FynnCloud's source code is publicly viewable, completely self-hostable, and free to modify or run for personal or micro-team use.

To support sustainable development, teams exceeding community or business limits obtain a commercial license. Crucially, after a rolling 3-year period, the code automatically converts to the standard open-source Apache 2.0 license.

Rolling Period 3 Years converts to Apache 2.0

Open at heart.

FynnCloud is open-source, community-driven, and fully self-hostable. Maintain complete ownership of your data and infrastructure.

1. TTFB (Time to First Byte) request latency benchmarks conducted in June 2026. Represents request execution overhead for sync delta polls in a clean schema state. Testing performed on a Raspberry Pi 5 (4GB RAM) hosting a release-mode FynnCloud server binary comparing against Nextcloud Enterprise v29 running in Apache with PHP-FPM container wrapper.

2. Server Memory Footprint represents base resident set size (RSS) utilization when starting up services in an idle state. Nextcloud Enterprise base configuration includes Apache, Redis cache database, and active PHP-FPM worker pools. FynnCloud runs as a compiled statically linked standalone server executable.

3. FynnCloud project is currently in early alpha stage of development. The APIs, desktop sync logic, and database schemas are subject to change. Not recommended for production storage deployments.
