    Hello HN, I have started FBG some years ago when I moved to the Bay Area and could not find a simple, cross-platform, no-registration way to play board games with my friends back in my home country. I also wanted to make it simple to create multiplayer board games online for developers in their free time. Shortly after, I found out about boardgame.io with similar goals and decided to join forces with them. It became the engine of our board games, and we focused on publishing/serving them. To be fair with everyone and inspired by Wikipedia, we made the project a non-profit with GPLv3…

    The initial idea for the game came during the final day of Game AI school in Cambridge. There, we had a Jam where we explored the idea of using LLMs as a game engine for fights. We then built a full web version in just a week. There is no need to register or pay to play. Test it out!

    I wanted to learn more about RAG implementations, so I built something to solve the constant digging through manuals whenever we play a game. It's fairly simplistic, but actually has worked pretty well for some of these conflicts. Everythings Open Source on GitHub if you're curious (or have ideas), and I'd love to hear feedback from fellow boardgamers!

    Hey HN, I'm Namanyay from https://gigamind.dev/. One of the most empowering applications of LLMs is enabling non-technical people to build apps and products. This value is reflected in the revenues of companies like Lovable and Bolt. Many of Giga's paying customers are business executives building valuable automations and internal tools that increase efficiency. But, the incumbents currently operate on pay-as-you-go pricing, which is a predatory business model that I ethically disagree with. I believe the future of vibe coding tool pricing needs to be outcome based vs PAYG.…

    LLMStack is a low-code platform that can be used to build LLM apps, chatbots and integrate AI experiences into existing products/workflows. It comes with everything out of the box that one needs to build LLM apps locally. It can also be used in a multi-tenant setting, making it available for everyone to use in an enterprise. Some highlights of the platform: - Chain multiple LLM models allowing for complex pipelines - Includes a vector database and necessary connectors to help enrich LLM responses with private data - App templates tailored to specific use cases to quickly build LLM apps…

    After adding "Human" as a LLM provider to OpenCode a few months ago as a joke, it turns-out that acting as a LLM is quite painful. But it was surprisingly useful for understanding real agent harnesses dev. So I thought I wouldn't leave anyone out! I made a small oss game - You Are An Agent - youareanagent.app - to share in the (useful?) frustration It's a bit ridiculous. To tell you about some entirely necessary features, we've got: - A full WASM arch-linux vm that runs in your browser for the agent coding level - A bad desktop simulation with a beautiful excel simulation for our computer…

    Hi HN, I've been working with LLMs in production for a while both as a solo dev building apps for clients and working at an AI startup. The one thing that always was a pain was to pay OpenAI/Gemini/Anthropic a few dollars a month just for me to say "test" or have a CI runner validate some UI code. So I built this server called ChunkBack, that mocks the popular llm provider's functionality but allows you to type in a deterministic language: `SAY "cheese"` or `TOOLCALL "tool_name" {} "tool response"` I've had to work in some test environments and give good results for experimenting…

    Built a simple web app that tells you which open-source LLMs will work on your hardware. It auto-detects your specs, shows compatible models from Hugging Face, gives realistic performance estimates (tokens/sec), and recommends quantization settings. You can also manually input specs to see "what if I upgraded my RAM?" Made this after wasting time downloading giant models only to find they crawled on my hardware. Hope it saves you some frustration!

    I got the chance to create a whimsical game about their latest Adaptive Pricing feature, despite Stripe being a very serious financial company. I'm in an interesting place being able to be paid to make games for a non-gaming tech company.
