Server-side rendering from structured intent
Montage compiles a small intent schema into production-ready HTML, CSS, and JavaScript on the server, so agents do not need to build UI markup directly.
Montage
Montage is an agentic UI rendering platform that turns structured agent output into rich, interactive UI components. It helps teams ship agent interfaces that render inside existing apps across web and mobile runtimes.
Overview
Montage is an agentic UI rendering platform that turns structured agent output into rich, interactive UI components. Instead of asking a model to generate finished markup directly, Montage compiles intent into scoped HTML, CSS, and JavaScript that can be rendered inside existing applications.
The product is positioned as a runtime for agentic UI and works alongside React, Vue, Svelte, vanilla HTML, and native mobile. The docs show a quickstart path that starts with an API key, a library install, and a generate step that returns HTML for rendering in a host app.
Core capabilities
Large component catalog
The platform ships with 248 atlas-backed components, including charts, diagrams, compositions, cards, tables, and content blocks, all compiled from a single API call.
Theming and responsive output
Components support theming and responsive layout, and the FAQ states you can apply your own brand tokens, fonts, colors, and spacing.
Framework-friendly rendering
The docs show outputs that can be mounted in React, and also in vanilla JavaScript, Vue, Svelte, or other environments through the SDK.
Interactive artifact workflow
Montage supports interactive artifacts, including streaming partial UI while the model is thinking and letting artifacts call back into your code for actions such as live data, save, or export.
Plan-based platform features
The pricing page describes render caching, hosted disposable UI links, shadow-scoped output, custom design tokens, batch rendering, and priority compilation on paid plans.
Common use cases
Agent UIs for end users
Build customer-facing agent experiences where the model needs to show a chart, table, form, or dashboard rather than plain text.
Operational agent workflows
Render sales, support, legal, healthcare, finance, ops, or coding workflows that need structured interface elements and controlled layout.
Embedding rendered artifacts in an app
Use the SDK quickstart to generate an artifact, then mount it inside React or a non-React frontend with the provided HTML block helpers.
Interactive artifact actions
Generate interactive components while keeping the host application in control of live data, save actions, or export behavior.
Branded product surfaces
Apply your own design tokens and layout rules when you need generated UI to match an existing brand system and responsive product shell.
Pros and Cons
Pros
- Works with a wide range of models, including Claude, GPT, Gemini, Llama, Mistral, DeepSeek, and custom fine-tuned models.
- Produces scoped HTML, CSS, and JavaScript that can drop into several frontend environments.
- Supports a broad template library, including charts, diagrams, dashboards, forms, timelines, and other agent-facing UI patterns.
- Offers theming and responsive rendering so output can match an existing product design system.
- Provides both community and paid support paths, with enterprise support and SLA options.
Cons
- Enterprise self-hosting is limited to VPC or on-prem deployments and is not available on Free or standard paid plans.
- The published docs emphasize a structured-output workflow, so teams need to adapt agents to emit the expected intent schema.
FAQ
What is Montage?
Montage is the runtime for agentic UI. It takes a small schema or structured intent from an agent and renders scoped HTML, CSS, and JavaScript on the server.
Which models does Montage work with?
Montage is model-agnostic and works with Claude, GPT, Gemini, Llama, Mistral, DeepSeek, and custom fine-tuned models.
What SDKs and frameworks does Montage support?
Yes. The docs show JavaScript/TypeScript support, a React helper, and a plain DOM mounting path. The FAQ also says official SDKs are available for JavaScript/TypeScript, Python, and direct HTTP integration, with framework helpers for React, Vue, Svelte, Next.js, and React Native.
How does support work across plans?
Free plan users get community support. Paid plans include email and chat support, and enterprise customers get dedicated support, a named solutions engineer, and an SLA.
Can Montage be self-hosted?
Enterprise customers can deploy Montage in their own VPC or on-prem environment. The FAQ says this is not available on Free or standard paid plans.
