Best open-source alternatives to Figma

Penpot is an open-source design and prototyping platform aimed at teams building digital products. It is positioned as a tool for designers and developers who want a shared, code-friendly workflow, with designs expressed in formats such as SVG, CSS, HTML, and JSON. The README emphasizes ownership of design infrastructure, self-hosting, and compliance-friendly deployment. The project supports real-time collaboration, design tokens, components, variants, inspect mode, plugins, and integrations through webhooks and an API. It is presented as deployment-agnostic, usable either as a SaaS offering or on self-hosted infrastructure, making it suitable for organizations that need scalable design systems and tightly integrated product development workflows.

Webstudio is presented as an open-source visual development platform aimed at developers, designers, and cross-functional teams. It is positioned as a product that lets users build visually while retaining ownership of their data, components, and infrastructure. The README indicates that the project can be used as a hosted service or self-hosted by rolling out one’s own instance. It also points readers to documentation, design resources, contributing guides, community discussions, and project tracking links, suggesting an active ecosystem around both usage and contribution. The license section further shows that the core is open source under AGPL-3.0-or-later, while one optional package is proprietary.

SVGEdit is a browser-based SVG drawing editor built in JavaScript. It is intended for users who want to create and edit SVG graphics directly in a modern web browser, and for developers who want to embed SVG editing capabilities into their own web applications. The project is organized around two main pieces: the editor UI and the underlying svgcanvas library. The README describes several ways to use it, including trying hosted builds, running it locally from source, and integrating the editor or canvas into another application. It also notes support for React-based extensions and provides guidance for contributing and testing the codebase.
