Best Screen Recording Tools for Capturing Bot Activity on Windows and Mac

✓ Built for advertisers who need clear, refund-ready traffic evidence.
If you need to capture bot activity on Windows or Mac, the best tools are OBS Studio, Camtasia, and the built-in recorders (Xbox Game Bar on Windows, QuickTime on Mac). OBS is free and powerful, Camtasia adds editing and annotations, and built-in tools are quickest for short clips. The right choice depends on how much proof you need, how long you'll record, and whether you need to edit the footage.
| Tool | Best for | Setup effort | Core workflow | Control/customization | Limitations | Takeaway |
|---|---|---|---|---|---|---|
| OBS Studio | Long, unattended captures with high control | Moderate – install and configure scenes | Record screen, audio, and webcam; output to MP4 or MKV | High – scenes, sources, filters, hotkeys | Steep learning curve; large files if not compressed | Best free option for serious bot evidence |
| Camtasia | Polished, edited evidence with annotations | Easy – install and record | Record, edit timeline, add callouts, export | High – full video editor | Paid license; heavier on system resources | Choose when you need to present a clear story |
| Xbox Game Bar (Windows) | Quick, short clips without extra software | Minimal – built-in | Press Win+G, record last 30 seconds or start/stop | Low – limited settings | No editing; may miss background activity | Good for a fast capture, not for long sessions |
| QuickTime (Mac) | Simple screen recording on macOS | Minimal – built-in | File > New Screen Recording, start/stop | Low – no editing, basic options | No annotations; limited format | Use for quick proof, not for detailed analysis |
Why screen recording matters for bot evidence
When you suspect bot traffic is hitting your ads or site, a video recording is concrete proof. It shows the exact behavior: rapid clicks, no mouse movement, or impossible speeds. Without video, you have logs and numbers that are harder to explain to a platform like Google or Meta.
Bot clicks can steal up to 20% of your ad budget, according to BotRefund. That's a significant loss. A screen recording gives you a visual record you can submit with a refund request.
How to choose a recorder for bot capture
Focus on four criteria:
- Recording length: Do you need to capture hours of activity or just a few minutes?
- File size and format: Will you need to compress or convert the video?
- Editing needs: Do you need to add annotations, zoom, or cut out irrelevant parts?
- System impact: Will the recorder slow down the very activity you're trying to capture?
For bot evidence, you usually want a tool that can run in the background without interfering with the browser or app you're monitoring.
OBS Studio: free and flexible
OBS Studio is open-source and free. It's the go-to for streamers, but it works just as well for recording bot activity. You can set up a scene that captures a specific window or the entire screen. You can also add a timestamp overlay, which is useful for evidence.
Setup takes a bit of time. You need to configure video and audio sources. But once it's running, it's reliable. You can record for hours without interruption. Output to MP4 or MKV, and adjust bitrate to control file size.
One downside: OBS can be resource-heavy. On an older machine, it might affect performance. Test it first.
Camtasia: polished evidence with editing
Camtasia is a paid screen recorder and video editor. It's ideal if you need to present your evidence to a platform or a client. You can record your screen, then edit the footage to highlight the bot behavior. Add callouts, arrows, and text to make the proof clear.
The workflow is simple: record, edit, export. Camtasia also lets you record system audio and webcam, which can help show the context. The downside is cost – it's a one-time purchase or subscription. It also requires a decent computer for smooth editing.
If you're building a case for a refund, Camtasia's editing tools can make your evidence much more persuasive.
Built-in recorders: Xbox Game Bar and QuickTime
Windows and Mac both have free, built-in recorders. Xbox Game Bar on Windows can capture the last 30 seconds or record continuously. QuickTime on Mac does basic screen recording. These are great for quick captures when you see something suspicious and need to grab it fast.
But they have limits. Xbox Game Bar is designed for games, so it may not capture all system activity. QuickTime records the whole screen or a selected area, but it doesn't offer editing or annotations. For long-term monitoring, they're not practical.
Other tools worth considering
Beyond the main three, you might look at Loom, ScreenFlow, or ShareX. Loom is cloud-based and easy to share, but it's not designed for long captures. ScreenFlow is a Mac-only editor similar to Camtasia. ShareX is a free Windows tool with many capture options.
For bot detection specifically, you might not need a screen recorder at all. Services like BotRefund automatically detect bots and capture video proof for each click. That's more efficient than recording everything manually.
Decision framework: which one should you pick?
Use this rule:
- If you need a free, long-duration recorder with full control, choose OBS Studio.
- If you need to edit and annotate evidence for a refund claim, choose Camtasia.
- If you just need a quick clip of a suspicious session, use Xbox Game Bar or QuickTime.
For most bot-capture scenarios, OBS is the best balance of cost and capability. If you're recording for a formal dispute, Camtasia's editing features are worth the price.
Limitations: when recording alone isn't enough
A screen recording shows what happened on your screen, but it doesn't prove the traffic source or the bot's identity. Platforms like Google and Meta require more than a video. They want logs, click IDs, and behavioral data.
That's where dedicated bot detection tools come in. BotRefund uses 106 independent checks to identify bots and captures video proof automatically. It also helps you file refund claims with Google and Meta. A screen recorder is a supplement, not a replacement.

FAQ
Can I use a free screen recorder for bot evidence?
Yes. OBS Studio is free and works well. It gives you control over resolution, frame rate, and file format. Just make sure you set a timestamp overlay.
Do I need to record the entire session?
No. You can record only the suspicious parts. But if you're not sure when bots appear, continuous recording is safer. OBS can run for hours.
What file format should I use for evidence?
MP4 is widely accepted. OBS can output to MP4, but be careful – if the recording stops unexpectedly, the file may be corrupted. Use MKV and remux to MP4 if needed.
Will screen recording slow down my computer?
It can. OBS and Camtasia use CPU and GPU. On a low-end machine, this might affect the very activity you're monitoring. Test with a short recording first.
Can I use a screen recorder to get a refund from Google or Meta?
A video alone is rarely enough. You need logs and behavioral data. BotRefund provides that and helps you file the claim.
