- The sync walk took its direction as a map of seven closures (direct-sync, inverse-sync). The two directions are fixed, so each is now a plain recursive function: sync-copy-recursive (main to copy, a sync or a reset) and update-main-recursive (copy to main), with sync-copy-shape and update-main-shape for the pair itself. Both share compare-children, which takes the children, a pair? predicate and four callbacks instead of 13 arguments; the inverse branch's call of the swapped callback, which could never run, goes. - The container of the main shapes is found once, at the start of the walk. The walk holds the :remote-synced a reset or an update main gives the copy shapes, instead of initial-root? and two branches. add-shape-to-instance and add-shape-to-main take the parent from the pair being walked instead of searching the whole subtree for it. - pcb/add-changes takes a container and the redo and undo changes, and applies them locally. Eight sync functions and the library typography sync each wrote that block; make-change goes from both namespaces. One list holds the attributes that link a copy shape with its main, and one shape-label prints shapes in the log lines. - change-touched chose what to write from three flags. It is now set-touched, which takes the value each caller computes. The swap's restore of the kept properties passes ignore-touched instead of calling it afterwards to put the groups back. - generate-sync-shape was a multimethod over the three asset types; it is a case in generate-sync-container. generate-sync-file loses its unused arity. The 100-line comment that opened the sync helpers described an older model; a short note points at the component sync contract. text-content-with-overrides only called txt/merge-overrides, which sync and switch now call. - update-flex-child-copy-attrs and update-flex-child-main-attrs are one function, update-flex-children, and the omit-touched? argument that was always false goes. - In the variant switch, sized-geometry-value builds the resized :selrect and :points that two geometry policies each built, and a binding of skip? shadowed by a second one is skip-attr?. add-shape-to-main keeps two changes that look wrong, now marked F102: its :reg-objects names the component, so it only reaches a deleted component's objects, and the undo of its new shapes deletes them from the copy's page. No behavior change: the golden masters and the suites are unchanged. libraries.cljc: 1816 -> 1284 lines.

Penpot is the open-source design platform for teams that build digital products at scale.
Penpot’s key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.
Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.
Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.
The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.
With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.
Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.
If your organization is scaling and needs extra support, we’re here to help. Talk to us

Why Penpot
Penpot connects design, code, and AI workflows through a code-based approach, making designs readable by developers and AI via the MCP server. This approach helps teams ship what’s actually designed and manage design systems at scale with powerful design tokens. As a self-hosted, open-source and real-time collaboration platform, Penpot offers full flexibility, security, and ownership without vendor lock-in. Learn more about why Penpot is the platform for your team.
Plugin system
Penpot plugins let you expand the platform's capabilities, give you the flexibility to integrate it with other apps, and design custom solutions.
Designed for developers
Penpot was built to serve both designers and developers and create a fluid design-code process. You have the choice to enjoy real-time collaboration or play "solo".
Inspect mode
Work with ready-to-use code and make your workflow easy and fast. The inspect tab gives instant access to SVG, CSS and HTML code.
Integrations
Penpot offers integration into the development toolchain, thanks to its support for webhooks and an API accessible through access tokens.
Building Design Systems: design tokens, components and variants
Penpot brings design systems to code-minded teams: a single source of truth with native Design Tokens, Components, and Variants for scalable, reusable, and consistent UI across projects and platforms.
Getting started
Penpot is the only design & prototype platform that is deployment agnostic. You can use it in our SAAS or deploy it anywhere.
Learn how to install it with Docker, Kubernetes, Elestio or other options on our website.
Penpot Enterprise
Penpot Enterprise is our paid plan for organizations that need to scale their design work across multiple teams with advanced governance, security, and administration. Manage teams and access from a centralized Admin Console, configure advanced permissions, and connect your identity provider through SSO. Available for cloud and self-hosted environments, it combines enterprise controls with Penpot’s open-source foundation and open standards.
