    Architecture as a code

    Architecture as a code

    Visualize, collaborate, and evolve the software architecture

    ...Inspired by the C4 Model and other architectural DSLs, LikeC4 lets you define your system’s structure in a textual DSL and then automatically generate consistent diagrams that reflect that design, ensuring that architecture documentation stays in sync with source code changes.

    Excalidraw

    Excalidraw

    Virtual whiteboard for sketching hand-drawn like diagrams

    ...While it has been extremely successful as a free open source project, the biggest source of complaints nowadays is around adoption within companies: How do you share diagrams with your co-workers easily?

So we decided to build a company around Excalidraw with the first product being Excalidraw+. With account-based access you can rest assured only the right people will have access to your data, while still retain the ability to share specific drawings with outside collaborators.
