There's a tool called Screen Studio that a lot of founders use to make their product look great in videos — the kind of demo where the cursor glides smoothly, the screen zooms in at just the right moment, and the whole thing looks like someone spent money on it. It costs $29 a month.
OpenScreen does the same thing, for free, with no watermark, and you can use it commercially — meaning in client work, investor decks, whatever you need.
Recent updates added a webcam overlay (so your face appears in the corner), undo/redo so you don't panic when you make a mistake, and cleaner motion effects. Over 11,000 people have starred it on GitHub in a very short time, which in the open-source world is a sign that something real is happening.
If you've ever wanted to show a client how something works, walk an investor through a feature, or post a product demo online without it looking like a screengrab from 2009 — this is worth an afternoon of your time.
You don't need a designer or a video editor. You just record your screen, and the tool handles the polish.

Open-source — The code is public and free. Anyone can use it, and a community of developers keeps improving it. No company can suddenly take it away or raise the price.
Watermark — That semi-transparent logo some tools stamp on your videos to advertise themselves. OpenScreen has none.
Commercial use — You're allowed to use it for paid work, not just personal projects. Important if you're making demos for clients.
