SimplyFlashback ⏪

Server-side replay recording

Minecraft 1.21.5-1.21.11. Paper and Folia also 26.1-26.2.

Discord

You record on the server. You watch the file in the Flashback client. People being recorded don't need the mod.

Getting started

1. Drop SimplyFlashback-*.jar in plugins/ and restart. No ProtocolLib.
2. /sf record start then /sf record stop when you're done.
3. Or /clip start, play for a bit, /clip save for the last 30 seconds.

Saves go to plugins/SimplyFlashback/replays/<Player>/ and clips/<Player>/. Open the .flashback in Minecraft with Flashback installed.

Features

• Works on Spigot, Paper, and Folia. One jar.
• Full recordings, plus a rolling clip buffer (last N seconds, 30 by default). Saving a clip doesn't clear it.
• Auto-save clips on death, leave, world change, or a player kill. All optional in config.
• Players can /autoclip themselves so they clip on join and save on those events.
• Grabs Simple Voice Chat audio if that plugin is on the server.
• Model Engine models don't snap back to spawn in the replay.
• First tick actually renders. The file includes registries, nearby chunks, and player state up front.
• Admin GUI, action bar (/sf actionbar), a TPS breaker if the server is lagging, and caps on RAM/disk.

Folia note: snapshots only cover the recorded player's current region. Stuff in other regions isn't in the file.

Commands

Aliases: /sf and /replay. Clips also have /clip, /sfclip, /highlight. Autoclip: /sfac.

Leave the player name off in-game to target yourself.

Command	Permission	Description
/sf record start [player]	simplyflashback.command	Start recording
/sf record stop [player]	simplyflashback.command	Stop and save to replays/<Player>/
/sf record [player]	simplyflashback.command	Toggle recording
/clip start [player]	simplyflashback.command	Start the rolling highlight
/clip stop [player]	simplyflashback.command	Stop without saving
/clip save [player]	simplyflashback.command	Save the last N seconds to clips/<Player>/
/autoclip [on|off]	simplyflashback.autoclip	Clip yourself on join; auto-save on enabled events
/sf actionbar [on|off]	simplyflashback.command	Toggle the capture HUD
/sf verify [file]	simplyflashback.command	Decode-check a file (errors=0 means it's fine)
/sf admin	simplyflashback.admin	Owner panel
/sf admin stats	simplyflashback.admin	CPU, heap, per-player RAM
/sf admin audit	simplyflashback.audit	Last lines of audit.log
/sf reload	simplyflashback.reload	Reload config.yml

Doing this to someone else also needs simplyflashback.record.others or simplyflashback.clip.others (default op). Death, world-change, and kill auto-saves need extra perms (simplyflashback.clip.death, .world-change, .kill), all default false so random players don't fill the disk. Leave saves have no extra perm unless you set one. simplyflashback.admin already includes command, others, reload, and audit.

Examples

Full session:

/sf record start Steve
/sf record stop Steve

Last 30 seconds:

/clip start Steve
/clip save Steve

Self-service:

/autoclip on

Then open the .flashback with the Flashback client.

Privacy

A recording includes whoever is nearby, unfiltered chat, terrain, and Simple Voice Chat audio if that plugin is installed. Lock down plugins/SimplyFlashback/ and tell people if you record them.
