I've been testing Cap.so for no other reason than some old habits die hard for this former software analyst. Whew that UI is so polished and crispy. Between the open source code, self hosted vids, editing features and price point -- gone give Loom some competition 🤞🏽

Tried @Cap v 0.3.beta and found an issue while exporting video. Wrote to @richiemcilroy about the problem and ~40 mins later the issue is fixed. I'm sold. Checkout Cap.so

No brainer instant purchase this morning: was looking for a solid screen recorder, for my new MacBook Pro, gave @cap a try, got myself a license within 10 mins — flawless UX sometimes speaks louder than lengthy marketer's words !

I've been looking for *ages* for a screen recording app that does the job + allows to zoom in/out easily and @Cap is AWESOME! Free, cross-platform, fully-featured, open-source. I mean...unless you love spending +$200 for recording your screen, use Cap!
