Image and video decision
Screenrat
A competent developer can reproduce ScreenRat's core (local screen capture, webcam overlay, local storage, one‑time unlock) using available open-source projects and macOS APIs; keeping the paid app is worth it only for the packaged UX, polish, and support.

Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Screenrat alternatives, with the arithmetic →
What a replacement has to do
- Record screen frames locally, optionally overlay webcam, encode to a video file, and save to the user's disk (one-off pro unlock to enable 4K).
What it still won’t have
- Polish, QA and platform-specific edge-case handling (e.g. macOS screen-capture permission quirks)
- Notarized app packaging and App Store distribution work
- Priority customer support and frictionless installer experience
- Professionally tuned 4K encoding presets and optimization for diverse hardware
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Screenrat does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a native macOS screen recorder in Swift using AVFoundation/AVCapture (or CGDisplayStream for high performance). Implement: 1) full-screen and selectable-area capture, 2) audio capture and sync, 3) webcam face-cam overlay compositing, 4) encoding/muxing to MP4/MOV with H.264 and HEVC presets including a 4K setting behind an unlock flag, 5) a minimal Cocoa UI for recording controls, file browser, and one-time license unlock, 6) signed DMG packaging and basic notarization scripts. Out of scope: cloud upload, multi-user sync, subscription billing, and a web dashboard. Include error handling for permission denial, disk-full and encoder failures, unit tests for encoder and file-write components, and end-to-end integration tests for start/stop flows.

- 3/3 assessment runs agreed+4
- Evidence score64
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
