PenPot

Penpot is a web-based, open-source design tool that fundamentally bridges the gap between designers and developers. It tackles the common "lost in translation" issues and eliminates handoff drama by expressing designs natively as code. This means what a designer creates is already structured as SVG, CSS, and HTML, allowing developers to inspect components and ship products faster.

The platform provides a comprehensive suite of features for a seamless workflow:

• Interface Design: Create beautiful UIs with powerful vector editing tools and custom fonts.
• Interactive Prototyping: Build interactive flows with transitions and user interactions to test concepts.
• Feedback & Sharing: Keep all stakeholders involved with easy sharing and in-context commenting.
• Code Inspection: Provide developers with ready-to-use specs and code snippets.

As an open-source tool, you retain full ownership of your work. Penpot's flexibility is further enhanced through an API, webhooks for custom integrations, and a growing library of community-built plugins.
