Stratum

A patched server runtime for real Vintage Story multiplayer load.

Stratum runs in place of the stock dedicated server, with over 150 direct game-file patches across networking, chunk pressure, entities, worldgen, anti-cheat, and per-tick overhead. Players connect with a normal client. You run Stratum for the game version your server is on.

What Stratum adds

One runtime instead of a stack of mods and scripts

Layer 01 // Performance

Runs better under load

  • Chunk sending shared fairly between players
  • Chunk generation budgets and smoother chunk IO
  • Movement-aware chunk priority and stale request cleanup
  • Async pathfinding with priority for work near players
  • Entity, block tick, and autosave smoothing
  • Lower per-tick overhead and less allocation churn

Layer 02 // Tools

Owner and staff tools built in

  • Homes, spawn, back, tpa, and private messages
  • Staff tools for vanish, freeze, jail, mute, warn, and notes
  • Player lookup with whois, seen, and near
  • Chat prefixes, nametag styling, and server info text
  • Permission based access for every command

Layer 03 // Protection

Guards against bad clients

  • Packet rate limits and queue back-pressure
  • Oversized custom packet rejection
  • Server-side block-break validation
  • Login protection during the join window
  • Optional client mod policy controls
  • Map and location privacy options for players

When a server starts to lag, the built-in reports give you somewhere real to look. Check timings, packets, queues, chunks, entities, players, and violations from in-game with the /stratum commands.

Get started

Three steps to a running server

  1. 1

    Download the release for your game version

    Grab the stratum-<version>-<rid>.zip for your platform from the releases page. Match the release to the Vintage Story version your server runs.

  2. 2

    Extract it

    Unpack the archive wherever you want the server to live.

  3. 3

    Run it

    # Windows
    StratumServer.exe
    # Linux
    ./StratumServer

    Needs the .NET 10 runtime on the host. On first launch Stratum downloads the matching vanilla server files, then runs the patched runtime on top. Your existing world and data folder carry over.

Good fit for

Who runs Stratum

  • Public multiplayer servers
  • Servers with busy spawn areas
  • Event and civ-style servers
  • PvP servers that want privacy and staff tools
  • Heavier modded servers that need better reports
  • Communities that want owner tools without a client mod

Before you switch

Compatibility

Stratum is built against a specific Vintage Story version, so use the release that matches your server. Players do not install anything extra.

Most normal server mods work, but Stratum patches deeper server internals than a regular mod. Test your mod list before you move a live server over.

Stratum is not compatible with Synergy or Tungsten. Those optimizations are already built into Stratum, so running them together conflicts.
