LLM-Friendly Full-Stack Go Framework — build complete web applications using only Go + WebAssembly, with minimal JavaScript. TinyWasm is a TUI-based development environment that acts as an intelligent intermediary between you, your LLM assistant, and your application.
⚠️ Active development. The TUI and MCP integration are evolving; expect rough edges. Source code is maintained privately — this repository distributes official binaries.
A TypeScript alternative for full-stack development — with Go everywhere. Write backend, frontend, and shared logic in pure Go; your project structure is the configuration. The TUI handles all infrastructure (compilation, hot reload, browser, MCP) so you and your AI assistant focus on application code.
Is it for you? Clear advantages, disadvantages, and who should (and shouldn't) adopt it: docs/WHY.md.
The typed, explicit code is the harness: an agent that doesn't know the library still builds correctly, guided by the signatures, while the compiler rejects what's wrong. Less to learn, fewer runtime bugs, smaller docs. → docs/CONSTRUCTION_HARNESS.md
curl -fsSL https://raw.githubusercontent.com/tinywasm/installer/main/scripts/install.sh | bashirm https://raw.githubusercontent.com/tinywasm/installer/main/scripts/install.ps1 | iexThe installer downloads the latest binary for your platform, verifies its SHA256 checksum, and places it on your PATH. Go and TinyGo are installed automatically — no prerequisites needed.
Update: tinywasm --update · Manual download: Releases (Linux amd64/arm64, macOS arm64/amd64, Windows amd64).
