## Streamdown

Streamdown is an open-source React component that renders Markdown as it streams in from AI models. Forked from react-markdown and hardened for streaming, it keeps formatting stable while tokens arrive — with built-in typography, streaming carets, animations, Shiki code blocks, KaTeX math, Mermaid diagrams and CJK support.

**Tarifs et offres:** Streamdown is free and open source. It is distributed as an npm package for React projects, with documentation, a playground and a public GitHub repository. Optional plugins are installed from npm at no cost; there is no paid tier or usage-based billing.

- **Typography and GFM:** Built-in Tailwind typography for headings, lists and code blocks, plus GitHub Flavored Markdown for tables, task lists, strikethrough and autolinks.
- **Streaming-first rendering:** Caret indicators show that content is still generating, unterminated blocks are parsed rather than broken, and transitions are animated for smoother output.
- **Interactive code blocks:** Shiki-powered syntax highlighting with copy and download buttons, automatic language detection and optional line numbers.
- **Math, diagrams and CJK:** LaTeX math through KaTeX, interactive Mermaid diagrams with fullscreen viewing, and CJK support so ideographic punctuation renders correctly.
- **Security and customization:** Unexpected-origin images and links are blocked and a link-safety modal shows the full URL before navigation. Override any element with custom components and tree-shakeable plugins.

**Forces:** Purpose-built for streaming AI output, so partial Markdown renders cleanly; Drop-in replacement for react-markdown with a familiar API; Rich defaults: Shiki code blocks, KaTeX math, Mermaid diagrams and CJK support; Tree-shakeable optional plugins keep the bundle lean

**Limites:** It is a rendering component, not a full chat application — you still build the surrounding app; Feature coverage depends on which optional plugins you install; Some integration decisions (plugin choice, animation tuning) require reading the docs first; Not a fit if you need a non-React framework renderer natively

## Tambo

Tambo is an open-source AI orchestration framework for React front ends that lets you connect your existing components so an agent can stream generative UI, manage state and speak through the interfaces you already ship.

**Tarifs et offres:** Tambo is now effectively free and open source: self-hosting the framework costs nothing and the code is publicly available. The previously offered Tambo Cloud free and paid plans are no longer available to new customers because the cloud service is shutting down on October 31, 2026; existing users should consult the shutdown announcement for their options.

- **Generative UI from your components:** Register your existing React components once and the agent renders them with the correct props, inheriting your styling, design system and business logic instead of inventing new markup.
- **Batteries-included agent plumbing:** Streaming, message threads, cancellation, error states, conversation storage and component state are handled for you, so AI features do not require rebuilding core app infrastructure.
- **Authentication-aware by default:** The agent inherits the signed-in user's permissions and session, keeping AI features inside your existing security and authorisation boundaries.
- **Client and server-side MCP support:** Model Context Protocol integration on both sides connects the agent to external tools and data sources, with MCP OAuth support for authenticated servers.
- **Multi-model and tool calling:** Bring your own model providers, define tools and let the agent route natural-language requests to the right components and actions in a single framework.

**Forces:** Genuinely open source and free to self-host, with a public GitHub repository and package; Renders your own components, preserving design-system consistency and existing logic; Handles authentication, streaming, state and error handling so teams avoid infrastructure work; First-class MCP support on both client and server side

**Limites:** Hosted Tambo Cloud is shutting down on October 31, 2026 and new cloud signups are closed; Self-hosting means you own deployment, scaling, model costs and ongoing maintenance; Requires a React front end, so it is not applicable to non-React stacks; Still a young framework, so documentation and ecosystem are evolving
