A nice GDSII layout editor
Fast. Intelligent. Accessible.
Why Rosette?
Fast
A Rust core and GPU rendering that keeps you in the flow. From geometry operations to live preview, every layer of the stack is built for speed.
Intelligent
AI-native from the ground up. Built for models and agents to enhance the fabrication, simulation, and design capabilities of your workflow.
Accessible
A clean Python API, a modern desktop app, and documentation written for engineers. Professional tools without the learning cliff.
What’s inside
Desktop app
A native app with a WebGPU-rendered viewer, hot-reloading preview, and design rule overlays. See your layout update in real time as you write code.
Python API
A clean, typed Python interface over a compiled Rust core. Ergonomic placement, automatic routing, and hierarchical cells.
Fabrication awareness
Built on PreFab’s process knowledge. Move beyond basic design rules with foundry models that have true predictive capabilities.
Agentic workflows
AI-native from day one. Agent instructions and direct code access gives LLM agents the context to design circuits alongside you.
Documentation
Guides, API references, and copy-paste recipes written for engineers. From first install to tapeout, every step is documented.
