Show HN: Anchor Engine – Deterministic Semantic Memory for LLMs Local (<3GB RAM)

Anchor Engine is ground truth for personal and business AI. A lightweight, local-first memory layer that lets LLMs retrieve answers from your actual data—not hallucinations. Every response is traceable, every policy enforced. Runs in &lt;3GB RAM. No cloud, no drift, no guessing. Your AI&#x27;s anchor to reality.We built Anchor Engine because LLMs have no persistent memory. Every conversation is a fresh start—yesterday&#x27;s discussion, last week&#x27;s project notes, even context from another t

Ask HN: How do founders process decisions without getting stuck?

Most founders I meet don’t want advice—they want validation. They’re buried under choices, conflicting opinions, and endless tactics. I’ve been testing a private space where founders can process decisions in real time—no advice, just clarity. I’m curious: if a space like this existed today, would it actually help you make decisions faster and avoid costly mistakes?

300 Founders, 3M LOC, 0 engineers. Here's our workflow

My co-founder Tyler Brown and I have been building our product for 6 months. The co-working space that Tyler founded that we work out of houses 300 founders that we&#x27;ve gleaned agentic coding tips and tricks from.Neither of us came from traditional SWE backgrounds. Tyler was a film production major. I did informatics. Our codebase is a 300k line Next.js monorepo and at any given time we have 3-6 AI coding agents running in parallel across git worktrees.Every feature follows the same four-pha

Show HN: Verified n8n community node for Anytype

I built an n8n integration for Anytype, the local-first encrypted PKM app. It supports full CRUD on objects and spaces plus raw API requests for anything custom. Verified by n8n, so it installs directly from the nodes panel!<p>Anytype&#x27;s API is relatively new, so this is one of the first automation integrations available for it. If you use both n8n and Anytype (or are curious about either), I&#x27;d love to hear what workflows you&#x27;d want to build.

Show HN: I built the first scripting language for multiplayer game dev

Hi HN,I&#x27;m one of the engine programmers at All Out Games (https:&#x2F;&#x2F;allout.game&#x2F;), a multiplayer-first gaming UGC platform where creators can make and play games with their friends. For scripting we wanted our creators to be able to jump in and create game mechanics without having to think about networking. If a developer had to manually send packets to&#x2F;from client&#x2F;server to get things to happen then we have failed. It is particularly bad if you are using AI tools bec

Show HN: NeoNetrek – modernizing the internet's first team game (1988)

Netrek is a multiplayer space battle game from 1988–89, widely considered the first Internet team game. It predates commercial online gaming by years, ran passionate leagues for decades, and is still technically alive — but getting a server up has always required real effort, and there’s been no easy way to just play it in a browser. NeoNetrek is my attempt to change that: Server: Based on the original vanilla Netrek C server, modernized with simpler configuration and containerized for one-comma
