Stone.js: your app exists in every runtime, until you run it

Short summary

Stone.js is a TypeScript framework that lets you write domain logic once and deploy it across Node HTTP, AWS Lambda, Azure Functions, GCP, edge runtimes, browser, CLI, and AI agents via MCP. It uses TC39 stage-3 decorators as runtime adapters that normalize platform events into a unified IncomingEvent. The author is seeking pilot users and claims 99% test coverage across 40+ packages with zero known vulnerabilities.
