Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

DevDiff VS Code Extension (v1.9.0)

Privacy-first, BYOAI (Bring Your Own AI) inline codebase intelligence and changelog generation for Visual Studio Code.

📦 Installation & Registries

DevDiff is published as a single, universal .vsix package providing identical functionality, offline privacy, and local AI capabilities across both official and open-source editor ecosystems:

Option A: VS Code Marketplace (VS Code, Cursor, Windsurf, Trae)

Option B: Open VSX Registry (VSCodium, Gitpod, Eclipse Theia, Code-OSS)

  • Install from Web: Open VSX Registry
  • Install via CLI:
    codium --install-extension ebula.devdiff

Option C: Manual VSIX Installation

Download the latest devdiff-1.9.0.vsix and run:

🔒 Privacy First

DevDiff never sends your code anywhere. It runs AI locally via Ollama by default. No telemetry. No analytics. No crash reports. Full disclosure →

DevDiff explains your Git diffs, parses abstract syntax trees (AST), and maintains persistent codebase memory directly inside VS Code. It is built from the ground up for developers who care about security, privacy, and understanding what changes enter their codebase.
