visualOS - The infinite canvas that stores your work as real files

Hey Product Hunt! 👋 We're Sarah and Gerald, a husband-and-wife team from Berlin. As creatives we've always organized our work on visual canvas tools like Miro or Milanote... But it always bothered us that our files and ideas were locked inside someone else's cloud. So we asked: why can't our own files, on our own device, be visualized the same intuitive way? What we started to build for ourselves became visualOS: 🗂️ Real files, not a database. Connect a folder and boards become actual folders on your disk, documents become Markdown files. Put the folder in iCloud or Dropbox and you have sync + backup. We run no servers at all. 🔒 Private by architecture. No account, no telemetry, works fully offline. There is nothing to leak. ⚡ Fast. Pure vanilla JS, no build step - ~5 ms render time with 3,000 notes on screen. 🕰️ Version history. Automatic rolling snapshots mean a sync conflict can't destroy your work. 💶 Fair pricing. The browser app is free, full-featured, no limits. The native iPhone/iPad/Mac app is a one-time purchase - €12.99 launch price for all three devices. No subscription, ever. It's single-user by design: this is your thinking space, not a team whiteboard. (Though the two of us do share ideas by pointing visualOS at a shared folder 😉 async sharing works; real-time collaboration is not our focus.) Try it right now, no signup needed: https://my.visualos.app - and tell us what you think. Every piece of feedback lands straight on our roadmap. 🙏
