Demos

Every match map produces a demo. 5Stack uploads, stores, parses, and serves it for you — the parsed data powers replay, playback, highlights, and stats.

How demos flow

1. The server records the demo and uploads it automatically when the map ends.
2. It's stored in S3-compatible storage (local MinIO by default, or your own provider — see Bring Your Own S3).
3. 5Stack parses it to extract rounds, kills, utility, positions, and stats.

You can also import a demo manually — upload a .dem to attach a match that wasn't played on your servers (for example a Valve or FACEIT match).

Downloading demos

From a match you can download a single demo as a .dem file, or all demos for a map as one archive. Downloads are served via signed URLs from your storage provider.

Admin controls

• Retention — how long demos are kept.
• Max storage — a cap on total demo storage.
• Network limiter — throttle upload/download bandwidth (or leave unlimited).

For where demos physically live and how to use your own bucket (e.g. Backblaze + Cloudflare), see Bring Your Own S3.
