Show HN: Open-Source Visual Wiki Your Coding Agent Writes for You

We’re Ruben, Afnan, and Theo. A couple of days ago we released the early repo for Davia and were surprised by how much feedback came in right away. We decided to turn it into a full open-source package you can run locally.

Davia is designed for coding agents to generate an editable internal wiki for your project. It focuses on producing high-level internal documentation: the kind you often need to share with non-technical teammates or engineers onboarding onto a codebase. Writing this kind of documentation takes forever, diagrams are often missing, and most tools don’t let you edit everything locally or integrate smoothly with your workflow.

Davia is open source. It produces an editable workspace: – Text lives in a Notion-like editor – Diagrams live on editable whiteboards – Everything runs locally and can be modified either in your IDE or in the workspace

One thing people found especially interesting is that you can delegate the documentation to your IDE’s AI agent. Davia handles all the heavy lifting. Your agent just writes the docs, and Davia turns them into structured pages, diagrams, and visuals.

The project is still early, and we’d love feedback, ideas, and examples of how you handle internal documentation today.
