GoKawiilYC-backed Whiteboard launches as open-source IDE for AI-assisted software design
A team backing Whiteboard (YC W26) released an open-source desktop app that lets developers and coding agents like Claude Code and Codex collaborate on a shared visual canvas. The tool connects to existing coding agents through an SDK, letting agents draw diagrams describing their work, which developers can then edit or annotate to guide further changes.
GoKawiil's interpretation of the reporting above, not reported fact.
By tying diagrams directly to code changes, Whiteboard aims to close a gap in prior visual tools that couldn't easily connect specs to actual implementation, according to the project's own description. Making the tool open source could let the developer community shape default prompts and behavior, potentially influencing how AI coding agents are guided in practice.
- Whiteboard is an open-source desktop app for human-agent software design collaboration.
- It integrates with existing coding agents such as Claude Code and Codex via an SDK.
- The project is part of Y Combinator's Winter 2026 batch.
