Overview

Daddy Recorder is a desktop recorder for Mac. One app captures screen, webcam, and microphone in a single pass, composites a cinematic cursor spotlight on top, and exports ready-to-share video. Ships as a DMG. No subscription, no watermark, no signup.

Problem

Creator-grade recording tools cost a lot. Screen Studio is around $229, Cursorful is $79, and the cheaper alternatives drop features the moment you need a webcam overlay or a decent cursor effect. If you record demos, walkthroughs, or product clips even occasionally, you are either paying for a tool you under-use or stitching together OBS, a cursor tool, and a video editor.

The things that actually make a recording feel polished are narrow and well-understood: cursor spotlight, smooth mouse motion, webcam inset, clean audio, and a no-friction stop-and-save flow. None of that needs to be premium software.

Approach

Daddy Recorder bundles the capture stack as a native macOS app and handles compositing in-process.

- Capture layer: Native screen capture (ScreenCaptureKit on modern macOS, AVFoundation fallbacks), webcam via AVCaptureSession, microphone alongside for synchronized audio
- Compositing: Canvas / offscreen compositing draws the screen frame, overlays the cursor spotlight at the live cursor position, and layers the webcam feed as a configurable inset (corner placement, shape, border)
- Cursor effects: Three styles - Glow, Ring, Solid - with configurable size and color. Composited into the output stream so the effect is baked into the exported file, not just visible during recording
- Export: MP4 or WebM, three quality tiers (1080p / 720p / 480p). Optional click highlights and mouse-smoothing applied during post
- Distribution: Signed DMG for macOS. One-drag install. Open source on GitHub for anyone who wants to inspect or fork

Key Decisions

- Desktop over browser-only: An earlier version shipped as a Chrome extension. It hit a ceiling fast - no access to the system webcam in a way creators liked, no microphone control, and recording quality was capped by browser constraints. A native Mac app unlocked all of that.
- One app, all inputs: Screen, cam, and mic in a single capture removes the whole "now import three files into a video editor and sync them" step. The output file already has everything aligned.
- Bake effects into the stream: Cursor spotlight, webcam inset, and click highlights all get composited during capture. The exported file needs no post-processing to look finished.
- DMG, not Mac App Store: Faster iteration, no review cycle, and no 30% cut. Trade-off is that users have to allow the app in System Settings on first run. Acceptable for the audience.
- Open source: The pitch is "Screen Studio but free." Open source is consistent with that pitch and lowers the trust barrier for giving an app screen + camera + mic access.

Challenges

Synchronizing three capture streams (screen, webcam, microphone) without drift across a multi-minute recording took more care than it looked. ScreenCaptureKit, AVFoundation, and the audio unit all have their own clock sources. The fix was to timestamp every sample against a single monotonic clock and align them at the encoder boundary.

Cursor spotlight compositing at 60fps on a retina display means pushing a lot of pixels per frame. Keeping the hot path allocation-free and using Metal-backed textures where possible brought CPU well under a sustainable level even during long recordings.

One-drag install means the app has to request screen recording, camera, and microphone permissions cleanly on first run. Getting the sequence right so the user is not bombarded with permission dialogs mid-recording was a UX fight.

Outcome

Desktop recorder working end-to-end on macOS. Screen, webcam, and microphone captured in a single pass. Cursor spotlight in three styles composited into the output. Exports clean MP4 or WebM at three quality tiers. DMG signed and ready to distribute. Next: Windows build, and a lightweight editor for trimming and adding callouts without leaving the app.
