Explore reference architecture diagrams inspired by public engineering blogs, whitepapers, and conference talks from leading technology companies.

Each architecture illustrates key distributed systems patterns including API gateways, microservices tiers, caching layers, message streaming pipelines, and polyglot persistence. Click "Use Template" to load any design into Diagram Studio as an editable diagram.

How to use this tool

  1. Browse architectures by category (Popular Companies, System Design, Cloud Architecture, AI & ML, Web & Mobile, Finance & Payments, SaaS) or filter by difficulty.
  2. Click "Preview" to inspect the high-resolution vector SVG topology, subsystem boundaries, example request flow, and cited technical references.
  3. Click "Use Template" to load the complete editable diagram into Diagram Studio with your own private copy.
  4. Customize nodes, rename services, adjust cloud boundaries, and export to clean vector SVG or high-resolution PNG.

Frequently asked questions

Are these official internal architectures of the listed companies?

No. These are educational reference architectures inspired by public engineering blogs, conference presentations, and standard system-design literature. They represent conceptual architectures rather than proprietary production setups.

Can I edit and customize the company architectures?

Yes. Clicking "Use Template" instantiates a fresh, fully editable copy in Diagram Studio where you can move components, add containers, change connections, and export.

Can I export the diagrams to SVG or PNG for my own design documents?

Yes. All architectures can be exported as watermark-free vector SVG or high-resolution PNG images suitable for RFCs, blog posts, and slides.
