ProtoPie vs Storybook: at a glance
What is ProtoPie?
ProtoPie opens an MCP server, putting agents inside the prototyping tool.
Version 10.3.0 ships ProtoPie MCP in beta, following a 10.x line that has been steadily about AI inside Studio. Version 10.0.0 introduced ProtoPie AI in beta, generating triggers, responses, and logic from natural language, alongside inline annotation blocks and a redesigned formula editor with error detection. The 10.1.2 release was consolidation on that base — response reliability, onboarding, AI availability extended to the China region, and Figma element conversion into editable states. The feed itself is noisy, repeating the 10.1.2 release across several rows with differing levels of detail.
What is Storybook?
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.

ProtoPie opens an MCP server, putting agents inside the prototyping tool.
◆ Current state
Version 10.3.0 ships ProtoPie MCP in beta, following a 10.x line that has been steadily about AI inside Studio. Version 10.0.0 introduced ProtoPie AI in beta, generating triggers, responses, and logic from natural language, alongside inline annotation blocks and a redesigned formula editor with error detection. The 10.1.2 release was consolidation on that base — response reliability, onboarding, AI availability extended to the China region, and Figma element conversion into editable states. The feed itself is noisy, repeating the 10.1.2 release across several rows with differing levels of detail.
◆ Where it's heading
The arc from 10.0.0 to 10.3.0 is a tool teaching itself to be driven by something other than a designer's cursor. Natural-language generation of interaction logic came first, Figma conversion reduced the cost of getting existing design work in, and an MCP server exposes the prototype to external agents. Release notes for the newest versions are thin — 10.3.0 is a single line — so the shape of the MCP surface is not yet visible in the changelog.
◆ Prediction
MCP in beta usually precedes documentation of what it actually exposes; whether agents can read a prototype's state or author triggers and responses is the question the entries do not yet answer. Given the Figma conversion work, the likely direction is agents that assemble interaction logic from imported design files rather than only inspecting finished pies.
Storybook
5.0DESIGN
The 10.6 alphas are an Angular tooling rebuild wearing a version number.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
