[Other] 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:&#x2F;&#x2F;github.com&#x2F;marcosiino&#x2F;pipeflow-php" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;marcosiino&#x2F;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&#x27;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&#x27;m already using it on two websites i&#x27;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&#x27;s editable via wordpress admin panel (using a wordpress plugin I&#x27;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&#x2F;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

[Other] Show HN: Serve 100 Large AI models on a single GPU with low impact to TTFT I wanted to build an inference provider for proprietary AI models, but I did not have a huge GPU farm. I started experimenting with Serverless AI inference, but found out that coldstarts were huge. I went deep into the research and put together an engine that loads large models from SSD to VRAM up to ten times faster than alternatives. It works with vLLM, and transformers, and more coming soon.<p>With this project you can hot-swap entire large models (32B) on demand.<p>Its great for:<p>Serverless AI Inference<p>Robotics<p>On Prem deployments<p>Local Agents<p>And Its open source.<p>Let me know if anyone wants to contribute :)

[Other] Show HN: OtterLang – Pythonic scripting language that compiles to native code Hey HN! I’ve been building OtterLang, a small experimental scripting language designed to feel like Python but compile down to native binaries through LLVM.<p>The goal isn’t to reinvent Python or Rust, but to find a middle ground between them:<p>Python-like readability and syntax Rust-level performance and type safety Fast builds and transparent Rust FFI (you can directly import Rust crates without writing bindings)<p>OtterLang is still early and very experimental. the compiler, runtime, and FFI bridge are being rewritten frequently.<p>Please star the repo, and contribute to help this project.

[Other] Show HN: I built a website to visualize company financial data Hi HN, I built a website myfinsight.com that aims to make complicated company financials easy to understand.<p>The problem: The go-to place for financial data such as revenue, sales, net income is Yahoo finance. However, their data is usually wrong and very limited. The numbers are hard to digest to get insight quickly. There are also numerous websites that provide much better data for a very expensive monthly fee.<p>Solution: a website that provides free diagrams and charts that visualize important financial data, such as income growth rate by date, revenue breakdown etc. It is free because the financial data process is highly automated without manual input and correction.<p>I used to send the finance infographics to friends and family. I found it easier just to make a website and they can grab the data from it.<p>Next steps: there is a long tail of companies that don’t file their reports correctly. I am trying to make it more accurate somehow, and maybe add live stock prices to the website. I am also looking for feedback! Please play around with it and let me know if something is wrong.

[CLI Tool] Show HN: Easily reduce GitHub Actions costs with Ubuntu-slim migration Hi, HN!<p>I&#x27;ve been running GitHub Actions workflows for a while, and when GitHub announced ubuntu-slim runners as a cheaper alternative to ubuntu-latest, I wanted to migrate. (Blog: <a href="https:&#x2F;&#x2F;github.blog&#x2F;changelog&#x2F;2025-10-28-1-vcpu-linux-runner-now-available-in-github-actions-in-public-preview&#x2F;" rel="nofollow">https:&#x2F;&#x2F;github.blog&#x2F;changelog&#x2F;2025-10-28-1-vcpu-linux-runner...</a>)<p>But manually checking which workflows can safely migrate is tedious—you need to check for Docker usage, services, containers, execution times, and missing commands.<p>So I built gh-slimify, a GitHub CLI extension that automates this. It scans your workflows, detects migration candidates, checks for incompatible patterns, identifies missing commands, and can safely update workflows with one command.<p>Try it: gh extension install fchimpan&#x2F;gh-slimify gh slimfy # Scan workflows gh slimfy fix # Update safe jobs only<p>Open source (MIT). I&#x27;d love feedback on how to improve it or what edge cases I might have missed.

[Other] Show HN: I built an HTTP client that perfectly mimics Chrome 142 BoringSSL and nghttp2. Matches JA3N, JA4, and JA4_R fingerprints. Supports HTTP&#x2F;2, async&#x2F;await, and works with Cloudflare-protected sites. Not trying to compete with curl_cffi - just a learning project that turned into something functional.
