Topcoat is a modular, batteries-included Rust framework for building full-stack, server-rendered web apps with async components and built-in client reactivity. It compiles reactive expressions to both server rendering and browser JavaScript, eliminating separate API layers and wasm bundles.

Use cases

• build a full-stack web app in Rust
• server-render HTML without a separate API layer
• add client-side interactivity without writing JavaScript
• build reactive UIs without a wasm bundle or client build step
• query the database directly from async components
• prototype web apps quickly with a batteries-included framework

When to choose

• you want a single-language Rust stack for server-rendered web apps
• you prefer simplicity and productivity over a sprawling ecosystem
• you want reactive client interactivity without a client build pipeline
• you're comfortable with early-stage software and breaking changes

When to avoid

• you need a stable, production-hardened framework with long-term API guarantees
• you need a large ecosystem of plugins and community libraries
• you're building a SPA or heavily client-side app
• you need fine-grained control over the client bundle
