Penpot

Penpot is an open-source design and collaboration platform for interfaces and other visual work. Its website explains vector-design tools, prototypes, team workflows, and the available hosted or self-managed options.

Teams can inspect the product's features and choose a setup appropriate to their collaboration needs. Hosting, account access, extensions, and support can have separate terms. A prototype or design file is distinct from a fully implemented application and still needs engineering and behavior checks when translated into a product.

For related tasks, Penpot can be considered alongside GitHub for code repositories, issues and change reviews and MDN Web Docs for web platform documentation, html css and javascript references. These resources cover adjoining parts of the subject; each publishes its own information and handles its own service, access arrangements or applications.
