Google launched a real-time streaming design agent and simultaneous multi-user collaboration for Stitch, its AI-native UI design tool, at I/O 2026 on May 20 — a direct challenge to Figma's position as the dominant paid platform in professional interface design.
Both features are available to global users at no cost, starting today. Figma's standard professional plan charges $15 per editor per month.
From Queued Prompts to Live Canvas
The I/O 2026 update replaces Stitch's previous turn-based workflow — submit a prompt, wait, review, repeat — with a continuous streaming model. The new Stitch Agent renders UI components directly onto the canvas as a designer types or speaks, reflowing layouts in real time before a generation is complete.
The practical difference is speed and control. Previously, a designer could only redirect a generation after seeing the finished result. With the streaming model, the agent can be steered mid-generation — stopping a layout direction that is heading the wrong way before it finishes, then redirecting. Google describes this as allowing users to "design, stream, and steer iterations in real time."
Voice input, first introduced in March 2026, is now tightly integrated into the streaming loop. A designer can say "give me three different menu options" or "show me this screen in different color palettes" and watch the canvas respond as they speak. The agent can also ask clarifying questions and surface alternatives through dialogue.
Multiplayer Editing Closes Figma's Core Advantage
Simultaneous multi-user editing was absent from Stitch until today. Independent reviewers and practitioners had consistently identified single-user operation as one of Stitch's most significant limitations relative to Figma, whose real-time multiplayer collaboration model has defined professional design workflows since the tool went mainstream. Google explicitly compares the new Stitch co-editing experience to simultaneous editing in Google Docs.
The I/O 2026 update also introduces an Agent Manager, an interface layer that logs a project's full evolution and helps teams explore multiple design directions in parallel.
Ecosystem Pipeline: AI Studio, Antigravity, Netlify
The new Stitch capabilities extend into Google's broader developer stack. Finished designs can be shared instantly via a link generated through Google AI Studio or exported to Google Antigravity for backend integration. Publishing directly to the web through Netlify is also available from within Stitch's interface.
The Stitch MCP server and SDK, which expose the platform's capabilities as machine-callable tools, let teams embed Stitch into automated workflows, CI pipelines, and third-party agents via the Model Context Protocol — meaning design generation can be triggered programmatically from an external coding environment.
DESIGN.md Format Carries Brand Rules Across Tools
A supporting capability that gained new significance with today's announcement is the DESIGN.md format, a plain-text file that captures a project's design system — typography, color palette, spacing, and component rules — in a format AI agents can read. First introduced in March 2026 and open-sourced under the Apache 2.0 license in April 2026, the format lets teams export a design system from one Stitch project and import it into another, or use it with compatible tools including Claude Code, Cursor, and GitHub Copilot.
The design rules carry forward across sessions without manual re-entry — a meaningful time reduction for teams managing multiple products under shared brand guidelines.
Gemini Powers a Free Tool Figma Charges For
Stitch runs on Google's Gemini model family and is currently available at no cost through Google Labs, with two generation tiers: Standard mode, using Gemini 2.5 Flash for rapid iteration, and Experimental mode, using Gemini 2.5 Pro for higher-fidelity output. No credit card is required.
Google has not announced long-term pricing, and the tool carries the standard uncertainty of any Google Labs experiment — it could evolve into a paid product, change substantially, or be discontinued. The company's history in the design tools space offers limited reassurance: Google Web Designer, launched in 2013, never gained traction against Adobe's Creative Suite.
Figma, meanwhile, is not standing still. According to its Q1 2026 earnings release, approximately 60% of the company's largest enterprise customers — those spending more than $100,000 annually — used Figma Make, its AI design feature, on a weekly basis during the first quarter, up from 50% the previous quarter. CEO Dylan Field described the moment as one where "design is the competitive edge — the craft, point of view, and human judgment that make a great product rise above the rest." Figma's stock declined roughly 12% over two sessions when a major March 2026 Stitch update — introducing multi-screen generation and an infinite canvas — triggered a fresh round of investor concern.
Stitch Excels at Ideation; Production Work Stays in Figma
Among practitioners, the emerging consensus is that Stitch and Figma occupy adjacent rather than identical roles. Stitch generates strong first drafts quickly; Figma provides the precision tooling needed to finish them. Nielsen Norman Group's "State of UX 2026" report, authored by Kate Moran, Raluca Budiu, and Sarah Gibbons, notes that AI-powered design tools have made it possible for "anyone to make a decent-looking UI" — while warning that this shift compresses the entry-level job market and raises the bar for what differentiates professional design work.
A survey of UX professionals by the UX Professionals Association, cited by Nielsen Norman Group, found that 47% of practitioners who used AI for design work saw "some value" in it, while 20% were not impressed — a split consistent with Stitch's documented limitations. Independent reviews consistently note that Stitch outputs trend toward the generic unless prompts are highly specific, and that color contrast and accessibility compliance require manual review before any generated UI ships to production.
The recommended workflow among practitioners using both tools: explore in Stitch, refine and finalize in Figma, build in Antigravity.
The I/O 2026 announcements advance Google's larger thesis: that specifying and building a user interface will eventually converge into a single, continuous conversation. Whether Stitch closes the gap with Figma in depth and production reliability in the months ahead will define how much of that thesis is achieved in practice.
