The short version: OBS Studio is the free open source screen recorder that most people should use, it’s stable, it does audio and webcam overlay, and it costs nothing forever. For quick simple clips without the learning curve, Kdenlive’s built-in screen capture or the older-but-solid ScreenStudio-style tools work too, though on Windows your fastest free option might already be sitting on your machine. I’ll tell you which one to pick in the next two minutes, and where each of them will let you down.
I recorded my first proper screen tutorial in 2019 for a client webinar on LinkedIn lead generation. I used a paid tool because that’s what everyone told me to use, and I paid roughly £15 a month for something I used four times a year. Five years and one rebuilt business later, I record screens weekly for training clips, client walkthroughs, and the odd bit of content for this site, and I haven’t paid a penny for the software since 2021. That switch to open source wasn’t about being clever with money, though it was that too. It was about not wanting a tool to hold my footage hostage behind a subscription I might forget to cancel.
The one to download: OBS Studio
OBS Studio (Open Broadcaster Software) is free, open source, and maintained by a proper community of developers, not a startup trying to upsell you six months in. It runs on Windows, Mac, and Linux. It records your full screen, a specific window, or a browser tab, and it lets you layer your webcam in the corner, which matters if you’re doing anything that looks like a tutorial rather than a silent screen capture.
Here’s the actual step-by-step, the version nobody bothers to write out:
- Download it from obsproject.com, it’s about 100MB, install takes two minutes
- Open OBS, click the plus sign under “Sources” and choose “Display Capture” (for your whole screen) or “Window Capture” (for just one app)
- Add a second source, “Audio Input Capture,” and pick your microphone from the dropdown
- If you want your face on screen, add “Video Capture Device” and resize the box into a corner
- Go to Settings, then Output, and set your recording format to MP4 (not the default.flv, trust me on this,.flv files cause headaches in editors later)
- Hit “Start Recording” in the bottom right, and “Stop Recording” when you’re done
Your file lands in whatever folder you set under Settings > Output > Recording Path. Most people forget to check this and then spend twenty minutes hunting for a video that was sitting in their default Videos folder the whole time. I did this myself the third time I ever used it, so don’t feel bad if it happens to you too.
What OBS is bad at
I’m not going to pretend this tool is perfect, because most articles on this topic act like OBS has no downsides and that’s just not true. OBS has a real learning curve if you want anything beyond “record my screen.” The interface looks like it was designed by streamers for streamers, because it was, originally built for people broadcasting to Twitch. If all you want is a quick 90-second screen clip to send a colleague, opening OBS and configuring sources and scenes feels like using a shipping container to post a letter.
It also doesn’t have a built-in editor. You record the raw file and then you’re on your own for trimming, cutting mistakes, or adding captions. If you need to edit, you’ll want a separate open source tool like Shotcut or DaVinci Resolve’s free tier (which isn’t fully open source but is free with no watermark, worth knowing about).
And here’s the bit that annoys me most when I see other writers gloss over it: OBS can absolutely tank your laptop’s performance if you’re recording at high resolution with a webcam overlay and running Zoom in another tab. I’ve had it eat through battery on my old MacBook Pro in under 40 minutes flat. If you’re on a machine that’s more than four or five years old, close everything else before you hit record, or you’ll end up with stuttery footage and a fan that sounds like a hairdryer.
If you just want something built in
Before you install anything, check what’s already on your computer. Windows 10 and 11 have the Xbox Game Bar (press Windows key + G) which records app windows, not your whole desktop, and it’s not open source, but it’s already there and it’s free. Mac users have QuickTime Player, which has a built-in “New Screen Recording” option under the File menu, also not open source, but again, zero install required.
Neither of these is what I’d call good for actual tutorials. The Xbox Game Bar refuses to record File Explorer or your desktop, which is maddening if you’re trying to show someone how to organise folders. QuickTime is basic but reliable for a quick 30-second clip. If you want something with more control and you don’t mind the small learning investment, that’s when you move to OBS.
The Linux and privacy angle nobody talks about
If you’re on Linux, or you care about your recording software not phoning home to a company’s servers, open source matters more than the word “free” does. Kazam and SimpleScreenRecorder are two lighter, simple options built for exactly this, no webcam overlay fuss, no scenes, just “click record, click stop.” They’re older projects and updates are slower, but for a basic screen grab on Ubuntu or Fedora, they still do the job in under a minute of setup.
This matters more than most people admit. A closed-source recorder can, in theory, send telemetry, usage data, even snippets of your recordings back to a server you’ll never see inside. With open source, the code is public, anyone can (and does) check what it’s doing. I’m not saying every paid tool is spying on you, most aren’t, but if you’re recording anything client-confidential, like a walkthrough of a customer’s CRM or their ad account, that transparency is worth something real.
What I use week to week
My honest setup: OBS for anything longer than five minutes or anything with a webcam, QuickTime for a 20-second “here’s the bug, fix it please” clip to my developer. I don’t use fancy transitions or scene switching, I record flat, then trim in a basic editor if needed. The whole point of choosing free software was to remove friction, not add a new hobby of learning broadcast software for its own sake.
If you’re choosing between screen recording tools for actual tutorial content rather than quick clips, it’s worth reading through how to choose screen recording software for tutorials, because the right tool depends heavily on whether you’re teaching, demoing, or just documenting a bug for a colleague.
One thing that trips people up constantly: audio sync. OBS occasionally drifts audio out of sync with video on longer recordings, especially past the 20 minute mark on older machines. The fix is simple but not obvious, go into Settings > Advanced and set your “Process Priority” to Above Normal, and make sure your audio sample rate matches across all sources. I lost an entire client training video to this once because I didn’t check it, recorded 35 minutes, and by the end my voice was nearly two seconds behind my mouse movements. Now I always do a five-second test recording first.
Where open source recording fits into a bigger workflow
Screen recording rarely lives alone. If you’re recording tutorials, you’re probably also thinking about note-taking during client calls, and it’s worth knowing the honest tradeoffs before you hit record on a sensitive conversation, which is exactly why I wrote about AI note-takers in client meetings. Similarly, if part of your workflow involves saving content from elsewhere, like grabbing a reel for reference, the same “free tool, but check what it’s doing” logic applies, and I covered that in my piece on saving an Instagram reel to watch offline.
And if you’re building out training material and wondering what else is free and not secretly a trial, my rundown of free AI tools that are really free covers the same territory, tools that don’t ask for a card number on day one and then quietly start charging on day fifteen.
The uncomfortable bit
Here’s what most guides on this topic won’t say out loud: free and open source doesn’t mean effortless. You will spend more time on setup with OBS than you would with a paid tool like Loom, which records in about four clicks with zero configuration. That tradeoff is real and it’s worth being honest about it upfront rather than pretending open source software is always the smooth option. You’re trading fifteen minutes of setup and the occasional audio-sync headache for permanent free use, full control over your files, and no company deciding one day that your export limit just changed. For a solo consultant or small business owner recording a handful of tutorials a month, that trade is almost always worth it. For a busy team that records fifty client calls a week and can’t afford anyone spending time fiddling with source settings, paying for something simpler might make more business sense, and there’s no shame in that either.
Frequently asked questions
Is OBS Studio really 100% free with no hidden costs?
Yes. OBS Studio is free open source software with no paid tier, no watermark, no recording time limit, and no account required. It’s funded through donations and sponsorships, not user subscriptions, which is why the interface doesn’t nag you to upgrade.
Can I record my screen and webcam at the same time for free?
Yes, OBS Studio does this natively. Add a “Display Capture” source for your screen and a “Video Capture Device” source for your webcam, then resize and position the webcam box wherever you want it on screen, no extra software needed.
Does open source screen recording software work on a Mac?
Yes, OBS Studio has a full Mac version, and Mac also comes with QuickTime Player’s built-in screen recording under File > New Screen Recording, which isn’t open source but is already installed and free to use for quick clips.
Why would I choose open source over a paid tool like Loom or Camtasia?
The main reasons are cost (permanently free versus a recurring subscription), transparency (the code is public so you know what the software is doing with your data), and control (no export limits, watermarks, or account requirements). The tradeoff is a steeper setup and no built-in editor, so you’ll need a separate free editor like Shotcut for trimming and captions.
