I’m building FGOTHS (For The GOTH Stack) for my own studio because I needed a way to bootstrap production-ready Go webapps with zero cloud overhead, no heavy JS frameworks, and a fast dev loop. It generates single static binaries (<10MB) targeting bare FROM scratch containers while delivering 100k+ req/s.

Key Features

Two Presets: api (Flat JSON API) and webapp (MVC + Templ + HTMX).
True HMR: Uses SSE + FlatBuffers to swap Templ HTML fragments in real-time, keeping form states, focus, and scroll position intact.
Zero CGO & Minimal Footprint: Compiles to a ~8.8MB binary with a low dependency surface area.
Embedded Runtime: Native reverse proxy, circuit breaker, health-checked failover, and deployment policies built right into the binary. The project is released under the Apache 2.0 license. I’d love to get feedback from the community on the architecture, the SSE/FlatBuffers HMR implementation, or the embedded runtime design!

📊 Benchmarks & Technical Metrics

FGOTHS is engineered for sustained high throughput, low tail-end latency, and predictable memory overhead.

Below are the metrics captured from load testing environments:

Metric Measured Value Architectural Context Throughput 100,000+ req/s Sustained load under concurrency Tail Latency (p99) ~2.2ms Low tail latency under saturation Binary Footprint ~8.8 MB Zero-CGO fully static binary Container Footprint < 10 MB Bare FROM scratch deployment

How FGOTHS compares to traditional web frameworks and monolithic stacks:

Why FGOTHS?

Vs. JS Frameworks (Next.js/SvelteKit): You drop the node_modules bloat, complex build pipelines, and high memory footprint while keeping a modern reactive frontend experience using HTMX and SSE-driven hot reloading.
Vs. Standard Go Frameworks (Gin/Fiber): FGOTHS isn’t just a router or micro-framework; it’s a project generator and embedded runtime that wires up Templ SSR, state-preserving HMR, and production-grade proxy/governance out of the box.
