Unifast: a Rust markdown/MDX compiler 25x faster than remark/rehype

Kenzo Wada — Fri, 20 Mar 2026 16:53:51 +0000

I built Unifast, a Rust-based markdown/MDX compiler.

In local benchmarks, it compiles about 25x faster than remark/rehype-based workflows.

I started this because I wanted a simpler and faster pipeline for markdown compilation, without carrying the complexity of multiple AST boundaries for common use cases.

It’s still early, so I’d love feedback on bugs, missing features, and real-world use cases.

[Tool] Thanks Stars 🌟 — A Rust CLI that stars all the GitHub repos powering your project

Kenzo Wada — Thu, 23 Oct 2025 08:48:39 +0000

Hey everyone 👋

I built a small command-line tool called Thanks Stars — it automatically stars all the GitHub repositories your project depends on.
It’s a simple way to say thanks to the maintainers who keep your stack running.

It’s inspired by teppeis/thank-you-stars, but completely reimagined in Rust, with first-class support for multiple ecosystems out of the box.

✨ Features

Detects dependencies from manifest files (Cargo.toml, package.json, go.mod, etc.)
Uses your GitHub personal access token to star repos on your behalf
Friendly progress output and summary
Cross-platform binaries and one-line installers

🧭 Supported Ecosystems

Cargo (Rust)
Node.js (package.json)
Go Modules
Composer (PHP)
Bundler (Ruby)

Want your favorite ecosystem supported next?

🚀 Install

brew install Kenzo-Wada/thanks-stars/thanks-stars
# or
cargo install thanks-stars
# or
curl -LSfs https://github.com/Kenzo-Wada/thanks-stars/releases/latest/download/thanks-stars-installer.sh | sh

🛠 Example

thanks-stars auth --token ghp_your_token
thanks-stars

Output:

⭐ Starred https://github.com/foo/bar via package.json
⭐ Starred https://github.com/rust-lang/cargo via Cargo.toml
✨ Completed! Starred 10 repositories.

💡 Why I built it

I often wanted to thank OSS maintainers, but manually starring dozens of dependency repos was tedious.
This CLI makes that gratitude effortless — and maybe reminds us that the open-source world runs on kindness (and stars).

Give it a try (and don’t forget to ⭐ the project itself 😉):

[Release] boundary.nvim – Visualize 'use client' boundaries in your React code directly inside Neovim

Kenzo Wada — Mon, 20 Oct 2025 08:25:18 +0000

Hey everyone 👋

I've just released boundary.nvim
— a Neovim plugin that helps you see 'use client' boundaries in your React codebase without leaving your editor.

Inspired by the RSC Boundary Marker VS Code extension
, this plugin brings the same visibility to Neovim.

✨ Features

Detects imports that resolve to components declaring 'use client'
Displays inline virtual text markers next to their usages
Handles default, named, and aliased imports
Supports directory imports (like index.tsx)
Automatically updates when buffers change (or can be refreshed manually)

⚙️ Usage

Install via lazy.nvim:

{
  'Kenzo-Wada/boundary.nvim',
  config = function()
    require('boundary').setup({
      marker_text = "'use client'", -- customizable marker
    })
  end,
}

Once enabled, you’ll see 'use client' markers appear right next to client components in your React files.

💡 Why

If you work with React Server Components, it can be surprisingly hard to keep track of client boundaries — especially in large codebases.
boundary.nvim gives you instant visual feedback, helping you reason about component boundaries at a glance.
