About

Weaver is an agent-native, cross-platform desktop widget platform — think Rainmeter, rebuilt for 2026. I’m building the entire framework almost from scratch: a Widget is a TypeScript component rendered by a Zig/QuickJS runtime through Weaver’s fork of Vercel Labs’ Native SDK — no browser and no webview. Widgets are crash-isolated, GPU-rendered where that is the measured winner, and presented with per-pixel transparency on the desktop layer.

Conjure. Share. Remix. Widgets are built by prompting your agent, shared as source, and remixed by anyone’s agent. A single TSX file is a complete widget:

import { useProvider, widget } from "@weaver/sdk";

export default widget({
  name: "Clock",
  size: [240, 110],
  anchor: { corner: "top-right", offset: [24, 24] },
  subscribe: ["time"],
}, () => {
  const time = useProvider("time");
  return (
    <column class="p-4 gap-1 bg-[#11141c]/86 rounded-2xl">
      <row class="items-baseline gap-2">
        <text class="text-3xl font-light">{time.hh}:{time.mm}</text>
        <text class="text-sm opacity-70">{time.ss}</text>
      </row>
      <text class="text-xs opacity-60">{time.weekday}, {time.month} {time.day}</text>
    </column>
  );
});

That file is also the distribution format: a shared Weaver widget is always its source — what you read is what runs, and every install is a potential remix.

Why Weaver is different

  • Prompt-to-desktop authoring: TSX, familiar hooks, and Tailwind-like classes give coding agents a surface they already know.
  • Native pixels without a browser tax: a small Zig runtime embeds QuickJS and projects retained operations into a native renderer instead of shipping Chromium with every widget.
  • Source is the artifact: a deterministic .weave contains readable source, assets, declared access, provenance, and remix lineage — never an opaque executable.
  • Isolation without duplicated collection: widgets fail independently; expensive system data is collected once by the host and fanned out only to subscribers.
  • Performance has receipts: CPU, memory footprint, wakeups, and frame cadence are product gates with measured tripwires, not silent guesses.

Current status

Early beta (v0), with developer builds for Windows and macOS. The authoring and source-sharing paths work end to end: scaffold → agent edits the TSX → weaver check → weaver dev → live widget. Expect everything to change.
