open-source canvas for thoughtful software design
Whiteboard is an open-source desktop app where developers and AI coding agents collaborate on software design. Agents like Claude Code or Codex plug in via an SDK and draw diagrams (sequence diagrams, ER diagrams) on a shared canvas, with clickable links from visuals to code, an AST-aware semantic diff viewer written in Rust, and a decision log showing what the agent chose autonomously.
Why now: It was just featured on Hacker News as a Show HN launch from a YC W26 company, which is driving attention.
Who it is for: Developers who use AI coding agents and want visual, reviewable explanations of the changes and design decisions those agents make.
