🚀 Spacewave

Self-host anything in the browser. Local-first apps with optional cloud sync, running natively or in the browser.

• 🌐 Local-first Apps run in the browser against an OPFS-backed object store
• ☁️ Optional cloud Fast cross-device sync and backup on Cloudflare
• 🦫 Portable Same Go code runs as WASM in the browser and natively as a CLI
• 🧩 Composable ObjectTypes, plugins, and packfile-based content addressing

ocpipe

Build LLM pipelines with OpenCode and Zod.

• Type-safe Define inputs and outputs with Zod schemas
• Modular Compose modules into complex pipelines
• Checkpoints Resume from any step
• Multi-model Works with 75+ providers through OpenCode

const Greet = signature({
  doc: "Generate a greeting.",
  inputs: { name: field.string("Name to greet") },
  outputs: { greeting: field.string("The greeting") },
});

const result = await pipeline.run(module(Greet), { name: "World" });

🏗️ Projects

Spacewave is built on the App Stack below. Get started building your own application on the stack with the project template!

🧱 App Stack

• ControllerBus - Dynamically configurable communicating control loops
• Bifrost - Cross-platform networking engine with pluggable transports
• goscript - Transpile Go to TypeScript
• ocpipe - Build LLM pipelines with OpenCode and Zod

SkiffOS is a minimal Linux distribution designed to run containers on embedded devices. It uses Buildroot to cross-compile a tiny system image with support for Docker and other container runtimes. SkiffOS enables running any Linux distribution or application in lightweight containers on embedded hardware.

🪶 Lightweight Protobuf

These are lightweight reflection-free code-generation based implementations of Protobuf designed to optimize binary size and performance, especially for WebAssembly (wasm) applications.

• StaRPC - Protobuf 3 RPC services over any stream multiplexer
• protobuf-es-lite - Lightweight TypeScript protobuf implementation
• protobuf-go-lite - Lightweight Go protobuf implementation
• protobuf-project - Template repository for projects using protobufs

Protobuf libraries like protobuf-es and protobuf-go focus on spec compliance and feature-complete implementations. These lite libraries focus on just the base proto2 and proto3 spec including RPCs to simplify the implementation.

🔌 QuickJS WASI Reactor

Run QuickJS-NG JavaScript engine in Go and TypeScript using the WASI reactor model for re-entrant execution:

• quickjs - QuickJS-NG fork with WASI reactor build target
• go-quickjs-wasi - Go module with embedded QuickJS-NG WASI command binary
• go-quickjs-wasi-reactor - Go module with embedded QuickJS-NG WASI reactor binary
• js-quickjs-wasi-reactor - Run QuickJS-NG within JavaScript with WASI reactor model

📚 Libraries

Common Go/TypeScript libraries:

• Common - Common project configuration files and Protobuf toolchain.
• Util - Go utilities for easy concurrent programming.
• go-kvfile - File format for storing a compressed key/value store
