* ✨ Add plugin with composable test framework and component tests The plugin provides a framework for writing composable tests against the Plugin API, and applies it to systematic end-to-end testing of component semantics. The framework's core ideas: a test is written once as a composition of operations over a starting configuration; choice points among the operations (optional steps, alternatives) expand the composition into a full sweep of test variants, so a single case definition yields broad combinatorial coverage; and the operations drive the real Plugin API with real change propagation, testing the full production implementation. The initial application is a suite of component test cases covering synchronization, overrides, swap slots and variants — the TypeScript/e2e continuation of the ClojureScript composable test suite (frontend_tests.composable_tests). Several cases originate from reproducing real defects (e.g. #10109 and the swap-slot corruptions). Tests run from an interactive panel in Penpot: cases are listed with plain-language descriptions, tests can be run selectively, results stream in live, and every checkbox carries a stable DOM id — so the panel can equally be driven programmatically (the basis for running the suite in CI), as documented in the plugin's README. Lives at plugins/apps/composable-test-suite as a regular member of the plugins workspace (init script, start:plugin:composable-test-suite, shared dev port 4202, covered by build:plugins via the new ./apps/*-test-suite filter). Related to #10584. AI-assisted-by: claude-fable-5 * ✨ Run the composable test suite headlessly in CI Adds a headless run mode for the composable test suite, following the plugin-api-test-suite's CI architecture, and a workflow that runs it as a per-PR gate. An in-sandbox entry (src/ci/headless.ts) runs the suite without the panel UI — the framework's runner was UI-free by construction, so no refactoring was needed — and streams each result through console markers, addressed by the same composite identifiers the panel uses (e.g. MainEditSyncs-2), with durations and, on failure, the error and the applied-steps transcript. It is built as a single self-executing bundle and evaluated directly inside a real Penpot plugin sandbox by the driver (ci/run-ci.ts), so no plugin dev server or port is involved. The driver needs no backend and no login: it serves the prebuilt frontend bundle via the frontend e2e static server and intercepts every backend RPC with Playwright fixtures. The mocked backend is not a limitation for this suite — everything it asserts is frontend store logic executed in memory — which the full run confirms: all 48 tests behave identically to the interactive panel, including variants and swap slots, with the single (currently expected) failure of MainEditSyncs-2 reproducing bug #10109 under the mock. TEST_FILTER selects tests by identifier substring; CI_TIMEOUT_MS bounds the run. The mock harness mirrors the frontend e2e harness (see the provenance note in the driver). Related to #10584. AI-assisted-by: claude-fable-5 * 📚 Restructure the composable-tests memory around both suites Present the composable component tests top-down: the shared framework principles upfront, then the two implementations — the ClojureScript suite in the frontend test tree and the TypeScript suite in the plugin, which tests fully end-to-end with a slightly more elaborate set of abstractions — and the plugin's headless CI run, pointing to the plugin's README for operational details. Also records this session's additions (geometry operations, case N, the CI harness). AI-assisted-by: claude-fable-5 * 📎 Refine the PR-description conventions in the creating-prs memory Encourage digestible descriptions: bullet items over prose (grouped by area with bold lead-ins for larger PRs) and no manual line wraps, since the rendered markdown adapts to the viewport. Also drop the outdated 'MCP' from the standard Note line.

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.
