In the physical world, pop-up stores are a way for brands to move fast — temporary spaces built to launch ideas, test markets, and connect directly with people. They’re agile by design: high impact, low friction, and gone before things get stale.
We’re bringing that same idea to the internet. Popup.so is a virtual pop-up space for web apps. A single domain where startups, indie hackers, and tech teams can take over for a limited time — to launch, experiment, or tell their story.
Each pop-up is temporary. You own the space for your slot, use it however you want, and when your time’s up, it resets for the next creator.
It’s a rotating showcase of what’s being built right now — simple, fast, and constantly changing. We believe the web should feel alive — not static pages, but moments.
This is our way to bring that energy back.
Each pop-up is temporary. When you book a slot, you get full control of the space — one clean domain, entirely yours for a set period. You can launch your app, run a campaign, tell your story, or share something new you’re building.
When your time ends, the next founder takes over. The site transforms — new product, new story, same shared stage. But here’s where it gets interesting. Every time you promote your pop-up, you’re also promoting the space itself — the idea of the rotating showcase. Your audience discovers what came before you and what’s coming next.
That means the visibility you build doesn’t just serve you; it compounds. Each founder benefits from the momentum of the ones before, and contributes to the success of those who follow. It’s a continuous loop of attention, energy, and discovery — a shared platform where everyone wins by showing up.
