Oxygen vs ProtoPie
A side-by-side editorial comparison of Oxygen and ProtoPie — release velocity, themes, recent moves, and the top alternatives to consider.
Oxygen vs ProtoPie: at a glance
What is Oxygen?
Oxygen spent its 6.2 cycle turning the builder into something an AI agent can drive.
Oxygen ships on long beta trains: 6.1 ran four betas plus an RC before landing, and 6.2 is now three betas deep. The defining change in 6.2 is an agent interface — an external AI agent can create and edit pages, templates, headers and footers, Components, selectors, CSS variables, dynamic data, interactions, animations, and site settings. Beta 3 adds the builder's first non-English UI, ending an English-only history. Everything else in the current window is regression cleanup.
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.

Oxygen
6.3DESIGN
Oxygen spent its 6.2 cycle turning the builder into something an AI agent can drive.
◆ Current state
Oxygen ships on long beta trains: 6.1 ran four betas plus an RC before landing, and 6.2 is now three betas deep. The defining change in 6.2 is an agent interface — an external AI agent can create and edit pages, templates, headers and footers, Components, selectors, CSS variables, dynamic data, interactions, animations, and site settings. Beta 3 adds the builder's first non-English UI, ending an English-only history. Everything else in the current window is regression cleanup.
◆ Where it's heading
The 6.1 cycle was breadth work aimed at the person in the canvas — multi-element selection, variable fonts, conditional classes, PHP 8.4 support. 6.2 changes the axis: rather than adding controls for a human to click, Oxygen is exposing the builder's object model so something else can write to it. Localization in Beta 3 pushes the same way, widening who can drive the builder rather than what it can draw. The cadence stays slow and fix-heavy, so the new surface will likely firm up before it grows.
◆ Prediction
Expect 6.2 to reach GA after another beta or RC dominated by agent-edit regressions, with the sibling Breakdance elements that ship alongside Oxygen 6 picking up the same agent-addressable surface.
ProtoPie
3.8DESIGN
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.
