Natyv is a native desktop app runtime with no bundled browser engine. Your app logic runs as a WebAssembly module via Extism inside a native host, no Chromium, no DOM, no JS runtime required. Benchmarked against Electron building the same real app: 27MB disk and 58MB idle RAM for Natyv vs 244MB and 331MB for Electron. WASM's linear memory only grows, so Natyv's host also recycles guest instances automatically to keep long-running apps lean. v0.1.0 and early. Go SDK live on pkg.go.dev.
