Show HN: Gametje – A casual online gaming platform
Hi all, I’ve been working on this project for a while but haven't shared it properly on Hacker News.<p>It is a casual gaming platform focused on simple multiplayer games that can be played in person with a central screen (like a TV) or remotely via video chat. You can also play on your smart Android based TVs via the app: <a href="https://play.google.com/store/apps/details?id=com.gametje">https://play.google.com/store/apps/details?id=com.gametje</a> (it was just released recently so could be buggy). It is also available directly in Discord: <a href="https://discord.com/discovery/applications/1215323000866607125" rel="nofollow">https://discord.com/discovery/applications/12153230008666071...</a> as an embedded activity.<p>It is playable in 9 languages and doesn’t require any downloads. Most games revolve around creativity in some shape or form. They can be played by just about anyone whether or not you consider yourself a “gamer”. If you can text, you can play these games.<p>Why did I create it?<p>Some of you may see the resemblance to Jackbox games. I have been a huge fan of them for 10+ years and enjoyed playing their games a lot. However, I found their support for other languages a bit lacking. While living in the Netherlands, I have encountered quite a few non-native English speakers and wanted to help them have a similar experience. Jackbox also has some fragmentation issues between app stores. I own their games on PC and PS4 but I can’t share a “license” between them. They also come out with a pack every year with 5 games. You never know if the game(s) will be fun, or if you should try to buy a previous pack with the one killer party game in it.<p>I designed Gametje with these issues in mind. It is playable in multiple languages with more being added regularly (feel free to request one). You can play it from any device with a web browser. There is no need to install it via Steam or a game console. All games are available in one place with no “packs” to buy.<p>What’s up with the name?<p>I have been living in the Netherlands for some years and part of my original motivation stems from wanting to give my friends here a game to play in their native language. It's way easier to be witty/funny in your mother tongue after all! Because of that, I wanted to incorporate something Dutch into the site's name. The suffix ‘-tje’ is one of the diminutive endings in Dutch and is meant to soften a word or make it "smaller". Game + tje = Gametje, or a little game. I have been informed by native Dutch speakers that it should have been ‘Gamepje’ to be "correct" but I liked the way Gametje sounded better.<p>Where can I try it?<p>Go here: <a href="https://gametje.com/" rel="nofollow">https://gametje.com/</a><p>You can test it out as a guest without signing up in order to get a feel for the games. Clicking into each game gives a short explanation and a small example of the gameplay. When creating a game room, you can choose to host via a central screen, host and play from a single device (like a phone) or cast the main screen to a Chromecast. There is also an Android TV app available that was just recently released: <a href="https://play.google.com/store/apps/details?id=com.gametje">https://play.google.com/store/apps/details?id=com.gametje</a><p>After creating a game room, you can join from another browser window or device. You can also add AI players if you want to try it out on your own, although it is a lot more fun with real people. I also created a discord channel: <a href="https://discord.gg/7jrftHuHp9" rel="nofollow">https://discord.gg/7jrftHuHp9</a> where you can find other users to play with. If you sign up for an account, you can opt-in as an alpha tester and see the new games as they are developed. It’ll also keep track of all your previous games and make sure not to duplicate content. You can review previous games as well and relish in your past victories.<p>What am I looking for?<p>I am interested in feedback about the whole concept and also the gameplay. Is it fun? What could be improved? Interested in helping out? Let me know!<p>Happy to share the more technical details as well for those that are interested. You can also read a bit about the platform and games in my blog:<p><a href="https://blog.gametje.com/" rel="nofollow">https://blog.gametje.com/</a><p>Thanks!

Show HN: Sparktype – a CMS and SSG that runs entirely in the browser
Hi HN,<p>After trying to teach a non-technical friend how to manage a Jekyll site I decided there must be a way to make building a site with a SSG easier. Options like Decap, Contentful etc. do make it a bit easier but still take lots of tech knowledge to set up.<p>So I built Sparktype, a browser-based CMS that outputs statically-generated HTML and CSS. My goal is for it to be as easy to use as Substack or Medium, while providing all the benefits of a static site generator including openness, simplicity, speed, security and ownership.<p>It handles most things that you'd need from a CMS, including creating pages, image resizing, menu management, tags, collections, listings etc. I've only made two themes so far, but I'm working on a theme store and the ability to import custom themes.<p>Content is saved as plain Markdown + YAML frontmatter and JSON config files, so there's no lock-in and content is easily portable to other platforms. Generated sites can be exported as a zip file to upload via FTP, committed to Github or published via Netlify API.<p>I'm working on cross-platform client apps using Tauri which will enable more publishing options as its not limited by what can be done in a client-only environment.<p>The way the system works means that the Web doesn't need to be the only interface to the content - here's a simple Go-based CLI client that bypasses the HTML altogether <a href="https://github.com/sparktype-project/sparktype/tree/main/st-cli" rel="nofollow">https://github.com/sparktype-project/sparktype/tree/main/st-...</a><p>It's very early days and there are still plenty of bugs, but I'm posting now to hopefully get feedback and see what people think. Please do let me know!
Show HN: Davia – Open source visual, editable wiki from your codebase
Hi HN,<p>We’re Ruben, Afnan, and Theo, and we’re building Davia to solve a common problem: documenting and explaining large codebases is complex. It takes too long to generate even a first draft of a wiki, visuals are essential to understand the structure, internal docs should be editable in the IDE, and most solutions aren’t open.<p>Davia is an open source tool. You enter the path of your repo, and it generates a visual wiki you can explore and edit. Diagrams are created automatically, and you can update everything either in your IDE or in a Notion-like editor.<p>The project is still early, and we’d love to hear feedback, ideas, or experiences from anyone interested in documenting and sharing code internally.<p>GitHub: <a href="https://github.com/davialabs/davia" rel="nofollow">https://github.com/davialabs/davia</a>

Show HN: DroidDock – A sleek macOS app for browsing Android device files via ADB
Hi HN,<p>I’m Rajiv, a software engineer turned Math teacher living in the mountains, where I like to slow down life while still building useful software.<p>I recently built DroidDock, a lightweight and modern macOS desktop app that lets you browse and manage files on your Android device via ADB. After 12 years in software development, I wanted a free, clean, and efficient tool because existing solutions were either paid, clunky, or bloated.<p>Features include multiple view modes, thumbnail previews for images/videos, intuitive file search, file upload/download, and keyboard shortcuts. The backend uses Rust and Tauri for performance.<p>You can download the latest .dmg from the landing page here: <a href="https://rajivm1991.github.io/DroidDock/" rel="nofollow">https://rajivm1991.github.io/DroidDock/</a>
Source code is available on GitHub: <a href="https://github.com/rajivm1991/DroidDock" rel="nofollow">https://github.com/rajivm1991/DroidDock</a><p>I’d appreciate your feedback on usability, missing features, or bugs. Thanks for checking it out!<p>— Rajiv

Show HN: Pipeflow-PHP – Automate anything with pipelines even non-devs can edit
Hello everyone,<p>I’ve been building [Pipeflow-php](<a href="https://github.com/marcosiino/pipeflow-php" rel="nofollow">https://github.com/marcosiino/pipeflow-php</a>), a PHP pipeline engine to automate anything — from content generation to backend and business logic workflows — using core modular stages and custom implemented stages (that can do anything), with the key power of using an easy to reason and read XML to define the pipeline logic, which every actor in a company, even non developers, can understand, maintain and edit.<p>It’s a *headless engine*: no UI is included, but it's designed to be easily wired into any backend interface (e.g. WordPress admin, CMS dashboard, custom panels), so *even non-developers can edit or configure the logic*.<p>It surely needs improvements, more core stages to be implemented and more features, but i'm already using it on two websites i've developed.<p>In future I plan to port it in other languages too.<p>Feedback (and even contributions) are appreciated :)<p>---<p>Why I built it<p>I run a site which every day, via a cron job:<p>- automatically generates and publish coloring pages using complex logics and with the support of the generative AI,<p>- picks categories and prompts based on logic defined in a pipeline,<p>- creates and publishes WordPress posts automatically, every day, without any human intervention.<p>All the logic is defined in an XML pipeline that's editable via wordpress admin panel (using a wordpress plugin I've developed, which also adds some wordpress related custom stages to Pipeflow). A non-dev (like a content manager) can adjust this automatic content generation logic, for example by improving it, or by changing the themes/categories during holidays — without touching PHP.<p>---<p>What Pipeflow does<p>- Define pipelines in *fluent PHP* or *simple, easy understandable XML (even by non developers), directly from your web app admin pages*<p>- Use control-flow stages like `If`, `ForEach`, `For`<p>- Execute pipelines manually, via cron, or on any backend trigger which adapts to your business logic<p>- Build your own UI or editor on top (from a simple text editor to a node based editor which outputs a compatible XML-based configuration to feed to pipeflow)<p>- Reuse modular “stages” (core and custom ones) across different pipelines

Show HN: PingStalker – A macOS tool for network engineers
Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN.<p>I live in the CLI, but when it came to discovery and monitoring, I found it limiting. So I built a GUI that brings my favorite tools together in one place.<p>PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted more: fast, reliable scans using ARP tables and ICMP.<p>As a Wi-Fi engineer, I couldn’t stop there. I kept adding ways to surface what’s actually going on behind the scenes.<p>A few highlights:<p>- Performs ARP, ICMP, mDNS, and DNS scans to discover every device on your subnet, showing IP, MAC, vendor, and open ports.<p>- Continuously monitors selected hosts (“live ping”) to visualize latency spikes, missed pings, and reconnects.<p>- Detects VLANs on trunk or hybrid ports, exposing when your Mac is sitting on a tagged interface.<p>- Captures just the important live traffic — DHCP events, ARP broadcasts, 802.1X authentication, LLDP/CDP neighbor data, ICMP packets, and off-subnet chatter — to give you a real-time pulse of your network.<p>- Decodes mDNS traffic into human-readable form (that one took months of deep dives, but the output is finally clear and useful).<p>- Built my own custom vendor-logo database: I wrote a tool that links MAC OUIs with their companies, fetches each vendor’s favicon, and stores them locally so scan results feel alive and recognizable.<p>Under the hood it’s written in Swift. It uses low-level BSD sockets for ping and ARP, plus Apple’s Network framework for interface enumeration. The rest relies on familiar command-line tools. It’s fast.<p>I’d love feedback from anyone who builds or uses network diagnostic tools:<p>- Does this fill a gap you’ve run into on macOS?<p>- Any ideas for improving scan speed or how traffic events are visualized?<p>- What else would you like to see?<p>Details and screenshots: https://pingstalker.com<p>Happy to answer any technical questions about the implementation, Swift APIs, or macOS permission model.
