## What it is
Sync-in Server is a self-hosted, open-source (AGPL-3.0) platform for file storage, sharing, synchronization, and team collaboration, written in TypeScript. It keeps files readable on the native filesystem while providing spaces, granular permissions, secure public links, WebDAV, desktop sync clients, full-text search, and online office editing via Collabora or OnlyOffice.

## Use cases
- self-host a dropbox or nextcloud alternative
- share files securely with password-protected expiring links
- sync files across windows mac and linux desktops
- collaborate on office documents in real time
- organize team file spaces with fine-grained permissions
- access files over webdav
- run a private cloud file server on my own infrastructure

## When to choose
- you want data sovereignty with files stored plainly on your filesystem
- you need a lightweight, performant alternative to Nextcloud for file sharing and sync
- you require consistent access control across web, WebDAV, sync clients, and APIs
- you want integrated office editing with Collabora or OnlyOffice

## When to avoid
- you need a broad app ecosystem with hundreds of community plugins
- you require features like calendar, contacts, or video calls in the same platform
- you cannot run MySQL and prefer a fully embedded database
- you need a fully managed SaaS rather than self-hosting
