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.

Show HN: Geofenced chat communities anyone can create
Hi HN<p>I built a location-based chatroom with Discord-like servers. This started as a portfolio project to learn WebSockets but has spiraled into something else entirely.<p>How it works.<p>There are two features right now:<p>Drop - Single chatrooms that can only be seen within a specified radius and only last for a time less than 48 hours chosen by the user.<p>Hubs - Geofenced servers modeled after Discord. These are not time restricted. They can be created by anyone and the creator becomes the admin able to add channels and set rules. When a user enters the location’s area, they can join the hub and continue seeing messages even after leaving. Hubs cannot overlap, so once one exists in an area another cannot be created on it. The hub will persist as long as it is being actively used. If unused for two weeks, it will be deleted. (Still implementing this deletion aspect, so that is not in the landing page at the moment)<p>Why I built this.<p>I do not like the feel of most social media anymore, but I really like my university’s discord server. I wanted something more general that provided similar interactions. So I thought something that might work is a more general social app tied to location.<p>I think if it is done right it can recreate the atmosphere that I liked. I thought a lot about what that atmosphere is. I think for social media to feel natural it needs a “third thing”: a shared interest or object that creates a connection between two people, or a neutral ground for communication.<p>Having something in common just makes the interactions better and more useful. I think location can serve as general thing in common, especially if the servers are curated by locals.
It could also be a good way for people to immediately connect in a new place.<p>Right now, I’m just having fun building this thing. I would honestly like to use it if other people were on there… and it was built better and an app.<p>Feedback<p>I’m looking for any feedback. What’s a good idea or what’s a bad idea. This is really just a prototype, so there are some rough edges, and I am actively working on it. If you find any bugs and feel like communicating them, please do. You can reach me at nhowar@uwo.ca
Show HN: I built a self-hosted error tracker in Rails
This project is inspired by 37signals’ ONCE idea. I replicated the whole process and have already sold a few copies (the testimonials are real).

Show HN: I built an HTTP client that perfectly mimics Chrome 142
BoringSSL and nghttp2. Matches JA3N, JA4, and JA4_R fingerprints. Supports HTTP/2, async/await, and works with Cloudflare-protected sites. Not trying to compete with curl_cffi - just a learning project that turned into something functional.
