Show HN: WhatsApp MCP running free on Cloudflare https://ift.tt/aBu3xNs

Show HN: WhatsApp MCP running free on Cloudflare I wanted my humble Claude on mobile to access my WhatsApp messages but the only options I could find either required WhatsApp Business or an actual server to run Baileys on. I wanted to run it for free on ClaudeFlare and with my personal WhatsApp account, so I built this. Important feature - it connects to your Google account as well as WhatsApp to grab the names of all your WhatsApp contacts, otherwise you get only phone numbers for many of them and search doesn't work properly. This is a single user install because it's both gray area and very private - so point your agent at the repo and let it set things up. https://ift.tt/yFNXpal October 19, 2026 at 03:06AM

Show HN: Ranet3 – High performance policy routed IPsec mesh SD-WAN btw this is already running on all my machines (including a macbook), and i've configured all of them to have routable public ip addresses ;) especially for the mac, my ISP is SFR (over coaxial connection) with only dynamic ipv4, i can use this to get stable v4/v6 addresses very easily for all my devices behind the router ios/android app soon^{TM} https://ranet3.com/ October 18, 2026 at 08:01PM

Show HN: Endo – A Higher-Order Harness https://ift.tt/CxhvkKN

Show HN: Endo – A Higher-Order Harness Endo is a Higher-Order Harness (HOH). From the easiest concept to understand to the more complex ones, Endo gives you: * A single, simple UI to use any agent provider with your existing subscriptions, and hot-swap agents right in the middle of a session. * An orchestration layer, which I call HOH, allowing arbitrary composition of agents to achieve any workflow. A fun case I tried was asking Fable and Astra to mock a presidential debate. * An agent protocol that abstracts any agent. The key insight here is that every LLM is an agent—instead of treating the LLM as just one node inside an external ReAct loop. Endo was a concept formed while I was building OpenChart ( https://ift.tt/XdAKcVy ). To power trading workflows, I needed to support scenarios where strict determinism is required, while still keeping the flexibility of an agent's inference-time decision-making capability. A new form factor was needed between rigid n8n-style workflows and open-ended ReAct loop agents. Thus the creation of Endo. Endo is short for Endomorphism, a term rooted in category theory and functional programming. An endomorphism is a function that transforms an object into another object of the same type. Similarly, Endo itself is built purely on functional programming principles, relying heavily on Effect ( https://ift.tt/HMW8ByZ ). ..And if you have patience to speak technical jargons, Endo is: * An agent orchestration layer—Higher-Order Harness (HOH)—where an entire agent is treated the same as a single LLM call, enabling arbitrary composition of extremely complex workflows. * A way to abstract any harness into a standardized protocol, where raw models and agents behave the exact same way, in a KV-cache-friendly manner. * A workflow engine that enables arbitrary composition of agents with a single workflow language. It's completely open source, and if you think this idea is cool, let's build together. Just for the fun of it. https://ift.tt/BJT0MeX October 16, 2026 at 03:02AM

Show HN: Forwarder.cc – Static-site forms sent to your inbox, pay per message https://ift.tt/muKYgJC

Show HN: Forwarder.cc – Static-site forms sent to your inbox, pay per message TL;DR: 12 years ago I built a service that forwards simple HTML forms to an email address. I've been procrastinating on finishing it ever since, until today. You point your form at it and every submission lands in your inbox. It runs on credits, 1 credit = 1 message, no subscription. Perfect for static websites. — Hey folks, back around 2014, alongside my job as a software engineer, I was building a lot of static websites for my own clients, mostly small businesses that just wanted a simple site. To avoid headaches, I went fully static, often hosted on GitHub Pages and similar. But most clients also wanted a contact form, and a form needs a server running somewhere. I had my own weekend-hacked service for this, which literally just forwarded the form to the client's email. I didn't invent anything here: one service I particularly remember was FormKeep by thoughtbot, that I really liked. So I started building my own, mostly because I loved losing myself in side projects like this, and also because I was a cheap ass and thought I could do something similar for less, and without a subscription. By 2016 I had done about 90% of what I'm showing you today. I called it "The Great Forwarder". Everything was ready: backend, frontend, hosting, Stripe, landing page. I even had a designer friend help with the design (sorry, Valentin, if I've botched it since). Then I started another project, which took off right away and took all my attention for a while. Fun fact: that project has been using this service ever since, and almost every message ever sent through it came from there. So for years, I kept Forwarder.cc up to date, upgrading libraries and trying new ones: axios, got, Redux, Zustand, create-react-app, webpack, Vite… It became my laboratory for everything I wanted to explore, while always staying up and maintained (again, for my own use only). The only thing that ever held me back from launching it was a missing help center, and, more honestly, the fear of putting it in front of people. So today's the day: after 12 years of procrastination, I finally finished the help center. I know there are a ton of similar services nowadays, but anyway, what do you think of that help center? https://forwarder.cc October 16, 2026 at 12:17AM
