What is Montage

Montage is a runtime framework for agentic user interfaces that eliminates the inefficiency of AI agents generating UI token-by-token. Instead, agents emit a tiny intent schema which Montage compiles server-side into production-ready HTML/CSS/JS components. This results in 10x faster hydration, 50-100x fewer output tokens, and seamless integration with any model or framework.

Key Features

10x faster hydration compared to streamed UI generation
50-100x fewer output tokens per render
Model-agnostic: works with Claude, GPT, Gemini, Llama, and custom fine-tunes
Framework-agnostic: supports React, Vue, Svelte, vanilla JS, and mobile
Full theming to match your brand's look and feel

Use Cases

  • Customer-facing AI agents that need to render dynamic UI without high latency or cost
  • Developers building agentic experiences who want to reduce token consumption and inference bills
  • Startups creating AI-powered products that require consistent, branded UI across interactions
  • Platforms that want to decouple UI rendering from the AI model to avoid vendor lock-in

Why do startups need this tool?

Startups building customer-facing AI agents need to minimize latency and token costs to deliver a smooth user experience without burning through their budget. Montage provides a ready-made solution that cuts inference bills drastically and allows teams to focus on agent logic rather than UI boilerplate. It also ensures brand consistency across all interactions, which is critical for early-stage companies establishing their identity.
