D2 Diagramming Language Goes Non-Profit Under Hack Club

D2 Is Non-Profit

D2, the open-source diagramming language, is now fiscally sponsored by Hack Club after its parent company shut down. Creator Alex will continue maintaining the project, but with limited time and a new AI-driven approach: all future contributions will use AI, and the project will prioritize a small, curated feature set over bloat. Non-goals include server-based features like MCP or APIs. The project aims for native integration with platforms like GitHub and Notion, a stable 1.0 release, and to become the most powerful harness for AI agents.

Models will find ways to squeeze every millisecond of performance in a way I could not.

    Just to be clear, this doesn't seem to be based on Walter Bright's D language. Maybe people already know that, but I didn't.

    Really happy to see this - A few months ago the D2 `play` site looked like it was down or unreachable and I was pretty bummed. It came back, but it did make me wonder about the future of the project - awesome to see that TALA will be released, sorry to hear the company behind it is shutting down.

    > D2 thus far has been a product of handcrafted code. That era is over. This next phase of D2 will be driven by AI. By this, I mean that all of my contributions will use AI.

    This is an interesting twist. While I get the rationale, I remain a bit concerned. I do hope the project remains successful, d2 is great!
