ScreenLink alternatives

Tested for a few days and really like the ability to record up to 4k with effects auto-added. The effects can be further tweaked in the editor. This provides a very smooth workflow, as the resulting footage can then be added into a full editor like Screenflow. Some cons I found - no audio voiceover/transcription, webcam overlay or the ability to automatically create "guides", like some of the competitors can. The developer is very open to feedback, and I hope some of these features would be rolled out shortly. Would also prefer if the licencing is for lifetime for earlier adopters, and not a yearly renewal.
