As answered by people managing Instant Replay and Codegres.org.
Instant Replay's answer
It works inside the OBS setup broadcasters already use, so there's no extra hardware or separate production software to buy. Clips stay on your own computer — no cloud uploads, no per-stream fees, no upload limits. It offers slow-motion down to 0.1×, frame-by-frame review, a replay queue, and one-button Stream Deck triggers. A free interactive browser demo lets you try the full interface before installing anything.
Instant Replay's answer
Instant Replay adds broadcast-grade replay directly to OBS Studio. Hardware replay decks cost five figures, and full vision mixers bundle replay into software you may not otherwise need. Instant Replay runs as an OBS Browser Dock — slow-motion, a replay queue, frame-by-frame review and Stream Deck control — with no extra hardware and no separate window.
Instant Replay's answer
Instant Replay started because broadcast-quality replays were only available through expensive hardware decks or full production suites. OBS Studio had a Replay Buffer that saved clips to disk, but no real way to play them back on-stream with proper controls. Instant Replay was built to fill that exact gap — a replay system that runs on a normal PC or Mac, inside OBS.
Instant Replay's answer
Instant Replay runs as a Browser Dock built with web technologies and connects to OBS Studio through the OBS WebSocket API. Video processing is handled with FFmpeg, and highlight detection uses motion analysis and audio-peak detection.

Live broadcasters who already use OBS Studio: sports, soccer, baseball, boxing, high school and college sports, esports tournaments, independent pro wrestling, concerts, and corporate event productions — anyone running a live stream that needs instant replays and slow-motion without a dedicated hardware replay system.
