deepfounder-ai/desigma is a free, open-source interface design tool built with Rust. The GitHub repository description presents it as a Figma alternative. According to the README, it is a local-first native desktop app that can also be used offline. The supplied FACTS do not record the latest release version. So this covers the features the repository currently describes rather than what is new in a specific version.
The tool is meant for interface design work: laying out screens and designing interactions. It supports frames and auto layout, components and variants, prototyping, and vector editing. It can import existing Figma files, and it also offers code generation and PNG/SVG export. It uses the Apache-2.0 license. What sets it apart is the breadth of scope: it goes beyond placing design elements to cover prototyping and file import/export. It is a project that offers that whole range in a Rust-based native desktop app.
The README, however, states that the current state is early alpha and describes it as not yet sufficient to replace professional day-to-day work. It is hard to judge real-world completeness or stability from a feature list alone. The supplied FACTS include no test counts or performance figures either. So rather than a finished Figma replacement right now, it is closer to a tool worth watching to see how far its feature scope backs real work at the alpha stage.
