## Code Arena

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.

**料金とプラン:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately.

- **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
- **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file.
- **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
- **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers.
- **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits.

**強み:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time

**制約・デメリット:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship

## 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.

**料金とプラン:** 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.

**強み:** 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

**制約・デメリット:** 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
