Flashback Server

Record your Paper/Folia server's gameplay into Flashback-format replays — entirely server-side. The players being recorded need no mods; you view the results with the Flashback client mod.

Features

  • Record any player server-side → .flashback files readable by the Flashback client.
  • Clip system — keep a rolling buffer per player and save the last N seconds on demand, or automatically when a player dies.
  • Folia-ready — works on the regionized Paper fork, no extra config.
  • Zero dependencies — pure Netty packet capture; no ProtocolLib to break on every update.
  • Renderable snapshots — recordings include a synthesized initial state (registries, chunks, player) so the Flashback client renders them from the start.
  • Multi-chunk recordings for long sessions + dimension changes.

Commands (flashbackserver.replay, default op)

Command Description
/replay start players <player> Start recording a player
/replay stop players <player> Stop & save a recording
/replay clip arm/disarm/save <player> Rolling clip buffer controls
/replay verify <file> Decode-check a saved replay (diagnostic)
/replay help Help

Configuration

  • clips.window-seconds (default 30) — rolling clip length.
  • clips.auto-clip-on-death (default true) — auto-save a clip when an armed player dies.
  • telemetry.enabled (default true) — anonymous, no-PII usage telemetry; set false to disable.

Install

  1. Paper or a Paper fork (Purpur/Folia) for Minecraft 1.21.5–1.21.11.
  2. Drop the jar in plugins/, restart. No dependencies.
  3. View replays with the Flashback client mod.

Privacy

Anonymous, opt-out telemetry (server platform/version, recording/clip counts & sizes, error class names). No player names, UUIDs, or IPs are ever collected. Disable with telemetry.enabled: false.
