About ViralBalls
ViralBalls started with a simple frustration. Bouncing-ball physics videos were everywhere, pulling in millions of views, and the only ways to make one were clunky. You either learned a game engine, paid for an app, or reposted a clip a thousand other accounts had already used. None of that felt right for someone who just wanted to make a good video and post it. So we built the tool we wished existed: open a tab, make the video, download it, done.
That idea still runs the whole site. ViralBalls is free, it works in your browser, and it asks nothing of you before you start. No sign-up. No install. No paywall sitting between you and a finished clip. You land on the simulator and the defaults already produce something worth posting. Everything past that point is you shaping it to fit your idea.
What we care about
We care about speed and control more than anything else. Speed, because the gap between an idea and a posted video is where most content dies. If making a clip takes twenty minutes and three apps, you stop making them. Control, because reposted content does not grow an account. When you set the mode, the colours, the pacing, and the hook yourself, the video is yours, and it stands a real chance in a feed that has already seen every recycled clip.
We also care about staying out of your way. The simulator updates as you change things, so you learn by doing instead of reading a manual. The settings use plain names. The hard part, the physics and the rendering, happens quietly in the background while you focus on the part that matters: whether the video is fun to watch.
Privacy by default
Your work stays with you. Presets and settings live in your own browser, and videos render on your own machine, not on a server we control. We are not in the business of harvesting your data or locking your creations behind an account. The less we know about you, the better the tool feels to use. You can read the specifics on our privacy policy.
Who makes this
ViralBalls is a small, independent project, not a venture-backed company with a roadmap full of upsells. That shapes what gets built. New modes and settings show up because creators ask for them, not because a sales team needs a feature to sell. When you send a note through the feedback page, it reaches the person actually working on the tool. A lot of what is in the simulator today exists because someone wrote in and said they wished it did.
Where it is going
The plan is to keep the core free and keep adding modes, effects, and quality-of-life touches that make a good clip faster to build. We write about the format on the blog, breaking down which settings tend to perform and why certain videos hook people, so the tool and the knowledge around it grow together. If you make something with it, that is the whole point. Go make a ball smash through some walls.
