[Other] Show HN: I'm rewriting a web server written in Rust for speed and ease of use Hello! I got quite some feedback on a web server I&#x27;m building, so I&#x27;m rewriting the server to be faster and easier to use.<p>I (and maybe some other contributors?) have optimized the web server performance, especially for static file serving and reverse proxying (the last use case I optimized for very recently).<p>I also picked a different configuration format and specification, what I believe is easier to write.<p>Automatic TLS is also enabled by default out of the box, you don&#x27;t need to even enable it manually, like it was in the original server I was building.<p>Yesterday, I released the first release candidate of my web server&#x27;s rewrite. I&#x27;m so excited for this. I have even seen some serving websites with the rewritten web server, even if the rewrite was in beta.<p>Any feedback is welcome!

[Other] Show HN: I created a cross-platform GUI for the JJ VCS (Git compatible) Personally, I think the JJ VCS (<a href="https:&#x2F;&#x2F;github.com&#x2F;jj-vcs&#x2F;jj" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jj-vcs&#x2F;jj</a>) hit a point some time in this past year where I find it hard to find a great reason to continue using git. Over the years I&#x27;ve cobbled together aliases and bash functions to try to improve my git workflow, but after using jj, which works with ~any git repo and integrates great with Github repos, all of the workflow issues I ran into with git are not only solved, but improved in ways I couldn&#x27;t manage with simple scripts.<p>One example is the op log, which lets you go to any point in your repo&#x27;s time and provides simple undo and redo commands when you want to back out of a merge, didn&#x27;t mean to rebase, etc.<p>Because I have a pretty strong conviction that JJ is at this point a cleaner and more powerful version of git, my hopes are that it continues to grow. With that, it seemed a proper full-featured GUI was missing for the VCS. There&#x27;s some plugins that add some integration into VS Code, and there&#x27;s one in the works to get Intellij support working, but many of the constructs JJ provides in my opinion necessitate a grounds-up build of a GUI around how JJ works.<p>Right now, Judo for JJ is an MVP in an open beta. I did my best to support all of the core functionality one would need, though there&#x27;s many nice-to-haves that I am going to add, like native merge support, native splitting, etc. Most of this will be based on feedback from the Beta.<p>I&#x27;m really grateful for the great community JJ has built, alongside the HN community itself in the countless VCS-based posts I&#x27;ve read over the years, and am hoping for lots of input here during Beta under real usage - the goal is to be a full-featured desktop GUI for the VCS, similar to many of the great products that are out there for git.

[Other] Show HN: I got tired of managing dev environments, so I built ServBay Hey HN,<p>For years, my local development setup has been a fragile mess of tools that never quite played nicely together. On my mac, it was a constant battle with Homebrew services starting (or not starting) on boot, conflicting PHP and Node versions managed by `asdf` or `nvm`, and a collection of `docker-compose.yml` files that I&#x27;d copy-paste and tweak for every single project. The cognitive load was just too high.<p>Setting up SSL was another chore involving `mkcert`. Sharing a quick demo with a colleague meant firing up ngrok. And if I wanted to run two projects that needed different versions of PostgreSQL? Good luck. I’d have to stop one service to start another.<p>I missed the simplicity of the MAMP&#x2F;XAMPP era, but I needed something that could handle the diverse stack of a modern developer – not just PHP and MySQL, but Python, Go, Rust, Node.js, and various databases.<p>That’s why I (along with my small team) built ServBay. It&#x27;s our attempt to bring back simplicity and speed to local development without sacrificing power. It&#x27;s a native app for macOS and Windows, not a wrapper around Docker or VMs.<p>Here&#x27;s what it does:<p>One-Click Stacks: You can install and run multiple, isolated versions of languages like Python, Node.js, Go, Java, Rust, Ruby, and .NET. No more path conflicts or environment variable hell.<p>Databases, Plural: This was a huge one for me. You can run multiple instances of MySQL, MariaDB, PostgreSQL, Redis, and MongoDB simultaneously. Project A can use Postgres 14 while Project B uses Postgres 16, both running at the same time on different ports.<p>Automatic SSL: Any host you create gets a valid SSL certificate out of the box. No more browser privacy warnings for `<i>.test` or `</i>.localhost` domains.<p>Built-in Tunneling: If you need to demo a feature or test a webhook, there&#x27;s a one-click button to expose your local site to the internet via a secure tunnel.<p>One-Click Local AI: This is something we&#x27;re really excited about. We&#x27;ve added a feature to easily download and run models like Llama 3 or Stable Diffusion locally through a simple UI, so you can experiment without worrying about API keys or costs.<p>Everything Else: It also handles one-click backups, has a clean, non-intrusive UI, and is designed to be as lightweight as possible.<p>I know what many of you are thinking: &quot;Why not just use Docker?&quot;<p>And that&#x27;s a fair question. We use Docker for production and complex, multi-service architectures. But for quickly spinning up a single-service app, testing a new framework, or just general day-to-day development, the overhead of `Dockerfile`s, `docker-compose.yml`, slow file sync on macOS, and resource consumption often feels like overkill. ServBay is for those moments where you just want to get to the code.<p>The project is still young, and we have a long roadmap ahead. I&#x27;m here all day to answer any questions, listen to your (brutally honest) feedback, and hear about what your own development workflows look like.<p>You can check it out here: <a href="https:&#x2F;&#x2F;www.servbay.com" rel="nofollow">https:&#x2F;&#x2F;www.servbay.com</a><p>Thanks for reading.

[Other] Show HN: Playwright Skill for Claude Code – Less context than playwright-MCP I got tired of playwright-mcp eating through Claude&#x27;s 200K token limit, so I built this using the new Claude Skills system. Built it with Claude Code itself.<p>Instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it. You get back screenshots and console output. That&#x27;s it.<p>314 lines of instructions vs a persistent MCP server. Full API docs only load if Claude needs them.<p>Same browser automation, way less overhead. Works as a Claude Code plugin or manual install.<p>Token limit issue: <a href="https:&#x2F;&#x2F;github.com&#x2F;microsoft&#x2F;playwright-mcp&#x2F;issues&#x2F;889" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;microsoft&#x2F;playwright-mcp&#x2F;issues&#x2F;889</a><p>Claude Skills docs: <a href="https:&#x2F;&#x2F;docs.claude.com&#x2F;en&#x2F;docs&#x2F;claude-code&#x2F;skills" rel="nofollow">https:&#x2F;&#x2F;docs.claude.com&#x2F;en&#x2F;docs&#x2F;claude-code&#x2F;skills</a>
