SwiftRec is a free, open-source screen recorder built on the Captura engine. Record your screen, mic, and system audio into a clean MP4 file—no watermark, no sign-up, no bloat.
When you search for an open source screen recorder, you're usually after one thing: a tool you can trust, inspect, and run without restrictions. SwiftRec fits that exactly. The source code is public under the MIT license, built on the well-known Captura engine, so you know what it does and what it doesn't do.
Unlike closed-source tools, there's no telemetry, no cloud sync, no account wall. You extract a ZIP, launch the app, and record. The files stay on your computer. The executable is tiny because it uses .NET Framework 4.7.2, which is already on every Windows 10 and 11 system.
Open source also means you can fork it, modify it, or study how screen capture works in Windows. If you need a custom version for your workflow, you have the freedom to make one.
**Tutorial or walkthrough:** Choose Full Screen or Window capture, turn on the mic, and toggle keystroke indicators so viewers see every action. Optional: add a webcam bubble for face-on-camera segments.
**Bug report or support ticket:** Record a specific window or region, skip the audio, and export as MP4 or animated GIF. GIF format works great for chat threads and issue trackers without needing a video player.
**Gameplay clip:** Pick Full Screen or Window mode, enable system audio to catch in-game sound, and use the global hotkey to start and stop without alt-tabbing. Check your game's rules before recording—some games have terms about what you can do with footage. Output is H.264 MP4, ready for YouTube or Discord.
**Podcast or screen-share prep:** Mux both mic and system audio into one file. You can hear game audio or a browser tab while your narration records on top—both tracks end up in the final MP4 with no extra work.
No. SwiftRec has no login, no cloud, no profile. Launch and record immediately.
Yes. No paid tier, no trial limit, no watermark on output. The source is open, the license is MIT, and there's nothing hidden.
SwiftRec is lightweight and runs on the .NET Framework already built into Windows. Recording uses your GPU where possible. For heavy sessions, close unused apps as you normally would.
No. You pick one source per recording: a window, a region, a full screen, or a monitor. Start and stop as many times as you need.
Yes. SwiftRec runs on Windows 10 (64-bit) and Windows 11, plus earlier Windows releases with .NET Framework 4.7.2.
New builds sometimes trigger SmartScreen warnings. Click 'More info' then 'Run anyway'. The app is open source and safe.
