Delay you switch on live
The jump lands on a keyframe while timestamps keep running — the viewer's player never sees a break.
OBS plugin // live delay
Add delay. Never reconnect.
LiveDelay sits inside OBS between you and the platform. Arm, Activate — viewers are 25 seconds behind you. Cut — you're live again. The stream never drops, not even for a moment.

What it does
Everything happens inside OBS itself — no second app, no browser dock.

Many platforms at once
Twitch, YouTube, Kick, Facebook or your own server. Each platform gets its own Start / Stop, autostart and buffer.

Native dock and hotkeys
A Qt panel instead of a browser page. Arm, Activate, Cut and “Cut after it airs” on a numpad or Stream Deck.

Mod / 05RAM buffer
Light, but in RAM
The delay buffer lives in RAM (not on disk). At 15 s and 6 Mb/s that is about 30 MB; longer delay or higher bitrate scales up. Settings show a limit and an estimate.

Full guide
Three steps to delay
Unzip into OBS
Close OBS, extract the zip into your OBS folder and confirm merging the folders.
C:\Program Files\obs-studio
Route OBS
Tools → LiveDelay → “Route OBS through LiveDelay”. Your server and key move to the platform list.
rtmp://127.0.0.1:1935/live
Control the delay
Set the seconds, Arm, wait for “armed”, Activate. Cut takes you back live — whenever you want.
ARM → ACTIVATE → CUT
Multistream // RTMP · RTMPS
One delay, every platform
OBS sends the picture to LiveDelay on your own computer. From there each platform gets its own stream — with the same delay and its own encoder.

What is LiveDelay?
An OBS Studio plugin that lets you turn stream delay on and off during a broadcast without dropping the connection to the platform.
Is it a separate program?
No. The buffering proxy runs inside OBS as part of the plugin. There's nothing else to install.
Will viewers see a jump or buffering?
On Activate and Cut the picture jumps to a keyframe, but timestamps keep increasing, so the player treats it as one continuous stream. Viewers see a cut in the picture, not a reconnect.
Does it work with Twitch and multistreaming?
Yes: Twitch, YouTube, Kick, Facebook and any RTMP/RTMPS server, several at once. Full Twitch Enhanced Broadcasting (GoLive) is not supported yet.
Do I need to change my stream key?
Not by hand. The “Route OBS through LiveDelay” button moves your server and key to the platform list and points OBS at rtmp://127.0.0.1:1935/live.
What if I close OBS while delayed?
The stream ends immediately and the last seconds in the buffer are never broadcast. Hit Cut before closing.
How much RAM does a long delay use?
The buffer is in RAM. Roughly MB ≈ bitrate_kb/s × seconds ÷ 8000. Example: 60 s at 8000 kb/s ≈ 60 MB per platform. Set the memory limit in the plugin; if it is too low, Arm refuses instead of eating all RAM.
Mac or Linux?
For now only Windows 10/11 x64 with OBS 31 or newer.
How much does it cost?
Nothing. The code is open source (GPL-2.0-or-later). If LiveDelay ever saves your stream, you can support the author.
