# Requirements

> What you need before installing Torrin.

## Host

* A **Linux** server with **Docker** and **Docker Compose**.
* **\~2-4 GB RAM** for the base stack (more if you run heavy usenet/torrent loads).
* **Disk** sized for your cache: at least `EVICTION_CAP_BYTES` (default 300 GB)
  plus headroom for the download scratch area. A separate data disk mounted at
  `/mnt/cache/store` is recommended.

## Accounts & services

* A **debrid account** (RealDebrid, AllDebrid, or TorBox) — this is what makes
  streaming instant. Users add their own key in the app.
* A **WireGuard VPN** provider for download egress (recommended). See [VPN](/self-hosting/vpn).
* A **domain** if you want to reach it from outside your LAN / use it with
  Stremio. See [Exposing publicly](/self-hosting/exposing).

## Optional

* A **Usenet provider + indexer** for NZB downloads.
* **Cloud storage** (Google Drive / Dropbox / OneDrive / pCloud / S3) if you want
  users to bring their own storage. See [BYOS](/self-hosting/byos).

<Note>
  Everything else — PostgreSQL, NATS, qBittorrent, the object store, and the
  Torrin services — is bundled in the compose stack. You don't install them
  separately.
