TinyWasm is an ecosystem of Go libraries (and a batteries-included dev environment) for building web apps where Go is the only language — backend, frontend, and shared logic — compiled to the frontend via WebAssembly with the smallest possible binary (TinyGo-first).

👉 Start here: tinywasm/app — the TUI dev environment with live reload, MCP for AI assistants, and one-command setup (installation and quick start live there).

• 🟦 One language everywhere — share types, validation, and logic across client and server. No TypeScript, no npm, no bundlers.
• 🪶 Tiny WASM — ~200 KB–2 MB depending on mode; TinyGo-first, no hidden allocations.
• 🤖 Built for AI — a Model Context Protocol server lets assistants see your UI, read logs, and control compilation.
• 🧰 Typed construction harness — APIs designed so the code is easy to read and hard to get wrong: the compiler rejects mistakes, so even an assistant that doesn't know a library builds correctly.
• 🔧 Zero config — your project structure is the configuration.

Go's WebAssembly potential is huge, but standard-library packages (fmt, strings, strconv, errors) bloat binaries — hurting web performance, edge deployment, and distribution. TinyWasm provides lightweight, TinyGo-compatible implementations with a familiar API: drastic size reduction, no compilation warnings, predictable performance.
