234 AI developers voted across a fragmented category where multiple platforms are shaping how AI applications get built and deployed. Here is what the results reveal.
The March 2026 IT Brand Pulse AI Brand Leader survey asked 234 members of the AI developer community to vote for Market Leader and Intelligence & Innovation Leader in AI App Builder Platforms, one of 26 products in the AI Engineering stack. Vercel took the top position in both categories, receiving 25.2% of votes for Market Leader and 21.8% for Intelligence & Innovation Leader. Replit finished second for Market Leader at 20.1%, while Gradio (18.4%) edged Replit (17.9%) for second in Innovation.
The results indicate a fragmented and competitive category without a dominant player. Innovation is broadly distributed across multiple vendors, suggesting several platforms are contributing meaningfully to how AI applications are built and deployed. The IT Brand Pulse analyst team expects this category to converge with broader platform plays as AI development workflows become more integrated.
What Are AI App Builder Platforms?
IT Brand Pulse defines AI App Builder Platforms as tools and environments that enable developers to rapidly design, prototype, and deploy AI-powered applications, often with minimal infrastructure overhead. These platforms provide capabilities such as UI generation, workflow orchestration, model integration, hosting, and deployment, allowing developers to move from idea to production quickly. They serve as the interface layer between AI models and end-user applications, accelerating the creation of interactive AI experiences. AI App Builder Platforms sits within the Development sub-layer of the broader AI Engineering stack, alongside AI Model Development Frameworks, Foundation Model Platforms, LLMOps Platforms, and AI Agent Development Frameworks.
