Penpot chases Figma parity while betting on self-host and AI-agent access
Penpot is the open-source, deployment-agnostic design and prototyping tool, and its releases run on two tracks: steady Figma feature parity (background blur, design tokens, export formats) and infrastructure that sets it apart — self-hosting, an MCP server for AI assistants, and a WebGL rendering path. Development is fast and community-heavy, with each numbered release carrying dozens of enhancements and fixes.
The 10.6 alphas are an Angular tooling rebuild wearing a version number.
Storybook is five alphas into 10.6.0, shipping roughly weekly. The dominant thread is Angular: Compodoc parsing extracted into its own package, docgen moved to the server, on-demand Compodoc runs, required inputs derived from Compodoc's own flag, and alias-collision handling corrected. Alongside it, TanStack support keeps getting patched into shape and TypeScript 6.0.3 landed in the first alpha.

Two bets run in parallel. One is closing the remaining gap with Figma feature-by-feature; the other leans into what a hosted competitor can't easily copy — private or on-prem deployment and agent-readable design files via MCP. The token-system depth and WebGL work suggest Penpot wants to be both a credible daily design tool and the default for teams that need control over where their design data lives.
Expect the parity grind to continue release-over-release, with the WebGL renderer maturing out of beta and the MCP and self-host story pushed harder as the differentiator against hosted rivals.

Two rebuilds are running in parallel. The Angular integration is being decomposed — parsing, docgen, and metadata pulled out of the framework adapter and into shared packages, with work moving off the client and onto the server. Separately, a component-metadata layer is forming in core (ComponentMetaManager, manifest component API fields, shared CSF story-shape helpers), which reads like groundwork for tooling that consumes Storybook's metadata rather than its UI. TanStack Start is being treated as a first-class router target rather than an edge case.
The Angular extraction looks close to done, so expect the remaining alphas to shift toward stabilizing the manifest and metadata APIs before a 10.6 beta.
