Flashback Server

Imagine being able to review every clutch play, every unexpected death, and every epic build session on your Minecraft server without ever asking your players to install a single mod. That is exactly what Flashback Server delivers. This lightweight Paper and Folia plugin records any player’s actions entirely server-side, producing .flashback files that you can watch later using the familiar Flashback client mod. Whether you run a competitive PvP network, a creative community, or a private survival world, Flashback Server gives you a powerful, zero-dependency replay system that stays out of your players’ way.

What Makes Flashback Server Stand Out?

Traditional replay mods require every participant to have the mod installed. Flashback Server flips that model. It captures raw network packets via Netty, so the recording process is completely invisible to players. The plugin then synthesizes an initial world state—registries, chunks, player data—so that the Flashback client can render the replay from the very first tick. This means you get clean, viewable recordings even for long sessions with dimension changes, all without ProtocolLib or other fragile dependencies.

Key Features

• Server-side recording – Capture any player’s gameplay without client mods. The plugin works silently in the background.
• Clip system – Keep a rolling buffer per player and save the last N seconds on demand, or automatically when a player dies. Perfect for catching those “Did that really happen?” moments.
• Folia-ready – Fully compatible with the regionized Paper fork. No extra configuration needed; just drop it in and it works across threaded regions.
• Zero dependencies – Pure Netty packet capture means no ProtocolLib, no breakage on Minecraft updates. The plugin is self-contained and future-proof.
• Renderable snapshots – Recordings include a synthesized initial state so the Flashback client can render them immediately, even if the recording starts mid-session.
• Multi-chunk support – Long recordings and dimension changes are handled seamlessly, preserving the full journey.

How to Install Flashback Server

Getting started with Flashback Server is straightforward. The plugin supports Minecraft 1.21.5 through 1.21.11 and runs on Paper, Purpur, or Folia servers. Follow these steps:

1. Download the Flashback Server .jar file from Modrinth or SpigotMC (search for “download Flashback Server” to find the latest release).
2. Place the jar into your server’s plugins/ folder.
3. Restart the server. No additional dependencies are required.
4. Verify the plugin loaded by running /replay help in the console or as an operator.

If you use the foxygame.net launcher, you can find Flashback Server in its add-on catalog and install it with one click, ensuring version compatibility with your Paper or Folia server. The launcher also handles auto-updates, so you never miss a critical patch.

Commands and Configuration

Flashback Server is controlled through a simple set of commands, all under the flashbackserver.replay permission (default for operators). Here are the essentials:

• /replay start players <player> – Begin recording a player.
• /replay stop players <player> – Stop recording and save the replay file.
• /replay clip arm/disarm/save <player> – Manage the rolling clip buffer. Arm a player to keep a buffer, then save it manually or let auto-clip-on-death trigger.
• /replay verify <file> – Decode-check a saved replay for diagnostics.
• /replay help – Display all available commands.

The plugin’s configuration file (plugins/FlashbackServer/config.yml) lets you tweak two main settings:

• clips.window-seconds (default 30) – How many seconds the rolling clip buffer retains.
• clips.auto-clip-on-death (default true) – Automatically save a clip when an armed player dies.
• telemetry.enabled (default true) – Anonymous usage telemetry; set to false to disable.

Viewing Your Replays

Once you have a .flashback file, you need the Flashback client mod to watch it. Install the mod on your own Minecraft client (available for Fabric or Forge), then load the replay from the mod’s menu. The recording will play back with full camera control, allowing you to spectate any player, slow down time, or fly through the world. Because Flashback Server includes the initial world state, replays start instantly without any missing chunks or entities.

Privacy and Compatibility

Flashback Server respects player privacy. The optional telemetry collects only anonymous data—server platform, version, recording counts, and error class names. No player names, UUIDs, or IP addresses are ever transmitted. You can disable telemetry entirely by setting telemetry.enabled: false in the config. The plugin is an independent project, not affiliated with the Flashback mod, but it produces fully compatible files for seamless interoperability.
