Sysonaut
Made for humans to create system design diagrams with impact
Sysonaut helps Architects, Consultants, Presales Engineers and Technical Illustrators communicate complex systems professionally. Model cloud, hybrid and on-premises architectures with a unified visual language across AWS, Azure and GCP. Export clean SVGs for PowerPoint, documentation and technical proposals, and switch the same diagram between flat 2D and isometric views instantly.
Most cloud architecture diagrams are still built in PowerPoint. Not because it’s a great tool for the job, but because dedicated alternatives rarely offer enough value to justify switching. That’s why I built Sysonaut: a focused editor for cloud and data center architecture that helps you create diagrams people actually want to present. It’s built for human-made diagrams used in sales decks, workshops, documentation, proposals, and architecture discussions—not infrastructure discovery.
What makes it different?
Built-in breadth: Sysonaut provides one consistent visual language across AWS, Azure, GCP, and on-premises environments.
Create your own visual language. Build reusable components ranging from simple icons to complex, multi-layered isometric objects with custom transformations, colors, labels, and embedded icons. Once created, reuse them across every diagram.
Keep your diagrams under your control. Open from a file and save back to a file. If you’re working on sensitive customer environments, nothing leaves your machine unless you choose to sync it.
Work anywhere. Once the editor has loaded in your browser, you can keep working even if your internet connection disappears—perfect for flights, trains, or unreliable Wi-Fi.
I’m continuously expanding the built-in cloud component library (you can see what’s available so far at https://www.sysonaut.com/components). Next on the roadmap is a Team plan, allowing organizations to share custom components through a shared team library. After that, I’ll be adding data modeling capabilities—but I’ll share more about those when they’re ready. Sysonaut is now in early access, and I’d love your feedback. If something feels missing—or simply doesn’t work the way you expect—please let me know. Your feedback will directly shape what comes next.
Happy modeling!

Who hunted Sysonaut?
Sysonaut was hunted by Johannes. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
