Open-source tools for visualizing chess positions.
We build software that turns chess notation into clear, high-quality images — fast, private, and free to use. Everything runs entirely client-side.

A high-performance visualization engine. Reads FEN notation and renders print-quality images (PNG, JPEG, SVG) at resolutions up to 30,208px. Built with React and the HTML5 Canvas API. No backend, no tracking, no uploads.
Made for people who need accurate diagrams without standing up a server — coaches, authors, and developers.
- Privacy first: No analytics, no cookies, no telemetry.
- Open source: Released under AGPL-3.0. Read, fork, and build freely.
- Quality enforced: Conventional commits, zero-warning lint gates, and automated reviews.
We welcome bug reports, features, and code! Read CONTRIBUTING.md for workflow details, or check our security policy for vulnerabilities.
