At Google I/O 2025, Google debuted Stitch, a new AI-powered UI generation tool, alongside a major expansion to its developer assistant Jules. These launches reflect Google’s growing ambition to reshape how web and app interfaces are built — by leaning into a broader trend in software development often called “vibe coding”: generating application logic or design with a prompt instead of code.
The Stitch and Jules tandem represents a strategic double-play: simplify UI creation for designers and non-coders while boosting developer productivity with smart backend automation.
Stitch: Design Interfaces with a Prompt (or Picture)
What is Stitch?
Stitch enables users to generate frontend designs by describing them in natural language or uploading an image.
It outputs HTML and CSS code, and even allows export to Figma, the de facto tool for product designers.
Users can fine-tune the design or export the code into an IDE for further editing, bridging the gap between visual ideation and development.
Why It Matters
Stitch isn’t a Figma replacement — but that’s by design. It aims to be the ideation layer: a way to get your first draft fast.
Its ability to ingest screenshots with annotations (coming soon) could significantly streamline UX feedback loops, a constant pain point in iterative design.
Powered by Gemini 2.5 Pro or Flash, it lets users choose between faster responses (Flash) or deeper logic generation (Pro), making it accessible for casual tinkerers and professional teams alike.
Market Context
Google is entering a crowded but early-stage market. Startups like Anysphere (Cursor) and Cognition are gaining momentum with developers, while Microsoft’s GitHub Copilot is quickly expanding.
Unlike general-purpose coding assistants, Stitch is narrowly focused on frontend generation, giving Google a wedge into the visual side of software development that others haven’t yet fully claimed.
Jules: Google’s Agentic AI for Backend Tasks
What Jules Does
Jules, now in public beta, is designed to help with code understanding, bug fixing, pull request generation, and maintenance tasks like version upgrades.
In a demo, Jules autonomously cloned a project, created a plan to upgrade Node.js from version 16 to 22, executed the plan, and verified that the site still worked.
What Makes It Different
While tools like GitHub Copilot assist line-by-line, Jules executes end-to-end workflows, reflecting the evolution of agentic AI — from co-pilot to co-worker.
The ability to switch AI models in the future gives developers flexibility over speed, depth, and context size — something few competitors currently offer.
Strategic Positioning
Jules is not just about productivity — it’s about trust and control. By sharing plans and seeking user approval before executing, it balances automation with oversight, which is critical in enterprise settings.
Google’s Play for the Dev and Design Workflow
These launches mark a significant expansion of Google’s Gemini strategy into the application layer of software development:
Stitch gives non-developers and designers a fast on-ramp to building UI, opening up creative workflows.
Jules tackles real-world dev pain points, like tech debt, patching, and upgrade cycles.
Combined, they hint at a broader ambition: an AI-integrated developer environment where Google tools guide you from whiteboard to production-ready app.
It also positions Google more competitively against Microsoft, whose GitHub Copilot and Copilot Workspace are evolving rapidly. Meanwhile, OpenAI’s Codex and tools like Replit Ghostwriter are creating pressure from below, with growing appeal to indie developers and educators.
Challenges and Tradeoffs
Limited scope (for now): Stitch is not a Figma or Adobe XD killer; power users may still need richer feature sets.
Trust in automation: Jules can refactor or upgrade code autonomously. This raises concerns about unintended changes, especially in large, legacy codebases.
Competitive speed: With rivals iterating fast, Google must avoid releasing tools that feel half-baked or lag behind.
Google’s Developer AI Stack Takes Shape
With Stitch and Jules, Google is finally stitching together a coherent vision for AI-assisted app development — from UI prototyping to backend maintenance. Rather than aiming to replace developers or designers, Google is clearly pursuing a collaborative AI vision, where the tools do the heavy lifting and humans remain in control.
As the vibe coding movement matures, Google’s success will hinge on one thing: how well these tools integrate into the workflows developers and designers already use — not just how well they generate code.
