How Bubble Doubled User Activation and Lifted AI Satisfaction 30% with Claude

Bubble is a no-code AI app development platform built on the belief that the best way for non-coders to build apps is to speak in their own language, not in code. With more than six million users who have built over seven million web and native mobile apps, Bubble's platform needed AI that could match their users' expectations—generating complete, production-ready applications from a single prompt while keeping users in control of every change.

Before AI, visual development required significant time to learn, and many new users churned before reaching the moment where the platform clicked. The team built a Claude-powered AI app generator to close that gap. The business impact was immediate: first-week user activation doubled, and twice as many users were still active at the end of their first month. But generating an app once wasn't enough—users needed to iterate. So Bubble built the Bubble AI Agent, a chat window inside the editor powered by Claude that lets users refine and extend their apps while staying in the visual builder.

Bubble evaluated multiple model providers before choosing Claude, prioritizing reasoning quality, low latency, and the ability to keep users in the driver's seat. The agent enriches every message with context about the user's app—elements, data schemas, logic—alongside instructions about Bubble's visual development language and a set of Bubble-specific tools for modifying apps. The agent proposes changes, the user approves them, and the edits are applied directly in the editor. When the team moved to Sonnet 4.6, it matched the output quality of larger models at lower cost and faster response times. "The resulting apps still have all the sophistication and visual quality we were previously seeing, but with much faster responses," said Zachary Tessler, AI Engineering Lead. The agent and app generator are built on LangChain and LangGraph, so migrating to the Claude API required minimal rework.

After switching, user satisfaction with AI-driven edit requests increased ~30%, with positive feedback rates climbing from roughly 70% to 90%. Internally, Claude Code changed how the engineering team thinks about what is worth building. Backlog items previously not worth the effort—like a frontend migration from jQuery to SolidJS—became feasible. The Notes panel and style variables subtab shipped. "It's less about things we couldn't do and more about things that weren't worth attempting before," said Zoe Lapomme, Engineering Manager. "The effort-to-reward ratio has shifted significantly." Claude API integrations on the Bubble platform trended upward throughout 2025, with Q1 2026 the strongest quarter to date.

Beyond Bubble's own product, builders in the ecosystem are now shipping Claude-powered apps through the platform—chatbots, content generation tools, document analysis workflows. Agency partners are building Claude-powered templates and plugins that other Bubble users can deploy, compounding adoption across the entire six-million-user base. "A Bubble user can connect to the Anthropic API, design a full conversational UI, and ship a Claude-powered product in hours rather than weeks," said Theo Goldberg, Partnerships Lead. "The compound effect across six million builders is what excites us most."
