Addfox: Build Better Browser Extensions for Developers and AI

GXY Gomi — Sun, 22 Mar 2026 16:41:41 +0000

🚀 A new open-source browser extension framework just dropped: Addfox (beta)

👉 github: https://github.com/addfox/addfox

👉 npm: https://www.npmjs.com/package/addfox

If you’ve built extensions recently, you’ve probably used tools like WXT or Plasmo.

They’ve pushed the ecosystem forward a lot — better DX, faster builds, less boilerplate.

But I built something a bit different: Addfox("Addon + Fox"). I want to "Build Better Extensionsfor Developers and AI".

⚡ What is Addfox?

Addfox is a browser extension framework built on top of Rsbuild / Rstack.

⚡ Rust-powered build performance
🧩 More predictable bundling behavior
🧩 Content UI support. Built-in createContentUI method for easy integration of Iframe, ShadowDom, and native content.
🧩 Framework agnostic. Vanilla, Vue, React, Preact, Svelte, Solid — use what you like
🧩 Zip on build. Build automatically outputs an extension zip package
🧩 Enable terminal error output with --debug. Capture all extension errors without browser DevTools, so you can Ask AI directly in any editor
🧩 Skills support for Agents
🧩 llms.txt and markdown metadata support
For more features, please visit the official website

📦 Current status

Beta released
Core workflow is stable
Not supporting Safari right now
Still iterating based on real-world usage

If you’ve ever felt constrained by existing extension frameworks,

or just want something faster and more transparent, give it a try:

Would love to hear how it compares to your current setup.

Supercharge Your Bun Workflow with bun-tasks

Supercharge Your Bun Workflow with `bun-tasks`

If you’ve ever wished Bun had a drop-in parallel runner like concurrently, meet bun-tasks—a Bun-first CLI that streamlines multi-command orchestration without leaving the Bun ecosystem.

Why `bun-tasks`?

Bun-native: Designed specifically for the Bun runtime—no Node shims, no compatibility hacks. Just run bun --version to make sure Bun is ready and you’re good to go.
Simple parallelism: Launch any combination of scripts or executables in a single line using the intuitive ::: separator. Quoting, environment variables, and script expansions are handled for you.
Smart env handling: Apply global flags with --args/-a, then fine-tune each command with its own variables. Local overrides always win, so tweaking command-specific settings is effortless.
Package-script aware: Referencing dev, serve, or another package script? bun-tasks automatically expands it to bun run <script>, keeping your commands DRY.
Safe programmatic API: Import the exported BunTasksCLI class for custom orchestration inside your own tools—nothing auto-executes on import.

Getting Started

Install the CLI (and make sure Bun is installed first):

bun add -D bun-tasks

Add a script that fans out to multiple tasks:

{
  "scripts": {
    "dev": "bun-tasks --args NODE_ENV=dev api ::: docs --args PORT=4000"
  }
}

Define your commands in package.json or point to executables directly:

{
  "scripts": {
    "api": "bun run src/api.ts",
    "docs": "bun run docs:watch"
  }
}

Run it:

bun run dev

bun-tasks merges your environment variables, launches both tasks in parallel, and prefixes their output—so you know exactly which command produced which logs.

Advanced Usage

Need fine-grained control? Import the CLI class:

import { BunTasksCLI } from "bun-tasks";

const cli = new BunTasksCLI();
await cli.run(["echo", "hello", ":::", "echo", "world"], {
  stdoutPrefix: (index) => `[job-${index}]`,
  mirrorStderrToStdout: true,
});

Customize prefixes, control stream mirroring, or embed bun-tasks inside a larger automation script.

Built with Trust

The codebase ships with full Bun test coverage (coverage display is fully supported on Linux/WSL; Windows coverage is still maturing). The CLI lives at bin.ts, and build artifacts are carefully curated—no .d.ts.map clutter.
