Facts checked on November 1, 2026 in each project's official docs. "If the panel is hacked" is our reading of them. Brume is shown in its recommended modes: Cloudflare Tunnel and Tailscale.

## Where Brume is different

- Zero open ports: traffic arrives through a Cloudflare Tunnel.
- Encrypted backups go to your S3 bucket and restore the whole server.
- One VPS bill, not per-Machine, volume and egress charges.

## Where Fly.io is better today

- 17 regions, with Machines spread across the ones you list.
- Idle Machines stop, then wake on the next request.
- Managed Postgres with a replica, failover and 10 days of backups.

**Pick Fly.io if…** Your users are worldwide, or your Machines should sleep when nobody calls them.

**Pick Brume if…** One location serves your users and you want a fixed bill and zero open ports.

## Install

```sh
curl -sSL https://brume.dev/install.sh | bash
```

Needs a fresh Debian or Ubuntu VPS and an S3-compatible bucket. Cloudflare and Tailscale recommended.
