Copilotz

One runtime for agents and the apps around them, on Node, Deno, Bun, Cloudflare Workers and the browser.

An app is plugins: agents that answer with tools and talk to each other and to people, conversations in shared spaces, memory, skills and routines, a usage ledger, people’s computers, sign-in and connected accounts, a developer API, WhatsApp. Each is a plain object built from the same few primitives (collections, Actions, Processors, Views, resources and adapters), and the runtime knows nothing else. Everything durable is an event, a document, an edge, a vector or a blob, written by one owner to one store (memory, SQLite or PostgreSQL), so every change is on the record and every screen follows it live: in a terminal, in a browser, or in an agent’s prompt.

Install

npm install copilotz                 # Node 24+ (npm, pnpm, yarn)
bun add copilotz                     # Bun
deno add jsr:@copilotz/copilotz      # Deno (or `deno add npm:copilotz`)

On Deno, name it copilotz in deno.json ("copilotz": "jsr:@copilotz/copilotz@^1.0.0-rc.20"), and the imports below are the same everywhere. Some pieces need a package of their own, installed beside it:…
