OBS Studio vs Rewind

OBS Studio is free, open-source software for video recording and live streaming on Windows, macOS, and Linux. It captures and mixes video and audio from windows, images, text, browser windows, webcams, and capture cards. Users can arrange unlimited scenes, switch with customizable transitions, and preview scenes and sources in Studio Mode before going live. Multiview can monitor eight scenes. The audio mixer has per-source filters, with VST plugin support, and hotkeys cover many recording and streaming actions. An API, native plugins, and Lua or Python scripts provide ways to extend the software. OBS supports streaming platforms including Twitch and YouTube, and streams connect directly from a user’s computer to the service. It is distributed under GPLv2 and may be used commercially subject to the license terms. The download page lists Windows 10 and 11 support, macOS 13.0 or newer, and Linux distribution through Flathub or an Ubuntu 24.04-or-newer PPA. The listed plan costs nothing, with no watermarks or usage limitations.

Rewind is free, open-source gameplay replay software for macOS and Windows. It continuously buffers the previous 15–60 seconds of gameplay and saves that window through a hotkey or when a game reports an event. Buffering can pause while you are at the desktop. Capture settings let you choose a display or application, select audio and microphone sources, configure storage cleanup, and rebind hotkeys. Encoding uses Apple VideoToolbox on macOS; Windows options include NVENC, AMF, Quick Sync, and x264. The clip library groups recordings by game and match, offers in-app playback, and shows event-type badges. Steam achievement detection reads local stats-cache files to save labeled clips without an API key or network connection. The README describes League of Legends tracking through its local Live Client Data API, with feature status varying by section. Integrations use sanctioned data sources or screen capture rather than memory reading, injection, or hooking. Rewind is GPLv3 licensed and labeled alpha; Windows capture is not yet validated on real hardware.
