Hey HN! We're so excited to show you Val Town (https://val.town)! A "val" is a JavaScript/TypeScript function or value that runs on our servers. We aim to get you from idea to running code in seconds: type code, run it, get its API endpoint, schedule it - all from the browser, in a couple keystrokes. We're a startup of 4 people, mostly in NYC. We've been working on this for 6 months and are eager for feedback from the HN community. Why do we need yet another online coding IDE? While researching devtools[1], I found myself wanting something halfway between Replit and Zapier: a…

Hi everyone, We’re building an open-source identity and risk management platform and we’ve just released the first chunk of code, a fully customizable KYC flow & UI, to the public. We’ve chosen to use Svelte so our flows would be lightweight (it is ~50kb gzipped). Next up: - Adding forms and components for it to be used as a full onboarding flow. - Releasing an open-source case management dashboard, for manual approval of users. - Releasing an open-source rule engine, to help automate decisions. We’d love to hear your feedback, suggestions, or any question you’ve got. And if the rest of the…

LLM Gatewayfree tier▲296I built an OpenAI-compatible LLM gateway that routes requests to OpenAI, Anthropic, Ollama, vLLM, llama-server, SGLang... anything that speaks /v1/chat/completions. Single Go binary, one YAML config file, no infrastructure. It does the things you'd expect from this kind of gateway... semantic routing via a three-layer cascade (keyword heuristics, embedding similarity, LLM classifier) that picks the best model when clients omit the model field, weighted round-robin load balancing across local inference servers with health checks and failover. The part I think is most…

Arch▲314Hey HN — I’m Adil from Katanemo (with Salman, Shuguang, and Meiyu) We previously shared an early version of this project as ArchGW. Based on customer feedback, the scope expanded from “LLM routing and model access” into something broader: delivery infrastructure for agentic applications. We renamed it to Plano and reworked the architecture accordingly. The problem On-the-ground AI practitioners will tell you that calling an LLM is not the hard part. The really hard part is delivering agentic applications to production quickly and reliably, then iterating without rewriting system code every…

Hi HN — we're the team behind Arch (https://github.com/katanemo/archgw), an open-source proxy for LLMs written in Rust. Today we're releasing Arch-Router (https://huggingface.co/katanemo/Arch-Router-1.5B), a 1.5B router model for preference-based routing, now integrated into the proxy. As teams integrate multiple LLMs - each with different strengths, styles, or cost/latency profiles — routing the right prompt to the right model becomes a critical part of the application design. But it's still an open problem. Most routing systems fall into two…

Hi HN, we built an open source model gateway. It's a single place to manage our own self hosted, frontier, and open source models in one place. It’s is rust native, built for concurrency, and implements all the config quirks across models and providers (streaming formats, tool calls, model parameters, rate limits, and different error behavior). The gateway adds under 1 ms for BYOK requests and under 2 ms when Experiential supplies the provider key. It has every major inference provider, and 1000+ models refreshed daily via a codex agent that opens a PR. Compared to other similar projects…

Hello, Hacker News! My name is Lillian (see: http://about.lillian.link/), and I just released version 0.2 of my MIT-licensed game engine, Hypatia(http://lillian-lemmer.github.io/hypatia/). Hypatia is a game engine for single player 2D action adventure games. You can use it to make a game like Legend of Zelda: Oracle of Ages and Oracle of Seasons. Hypatia is aimed at non-programmers and programmers alike. I'm seeking any sort of feedback. Hypatia supports FreeBSD first, but has great support for just about any platform…

I’ve been a long-time Snowplow user and unofficial evangelizer. I have deep respect for its founders, Alex and Yali, who I met a few times. What made me fall in love with Snowplow was that it was unopinionated, gave access to raw event data, and was truly open source. Back in 2013, that changed everything for me. I couldn’t look at GA the same way again. Over the years, analytics moved into SQL warehouses driven by cheaper CPU/storage, dbt, reproducibility, and transparency. I saw the need for a democratized Snowplow pipeline and launched a hosted version in 2019. In January 2024,…

Hello! We at Val Town have spent the last couple months redesigning our product around a new core primitive: Val Town Projects. Why: Our prior core primitive, a "val", was too small. A val is just a single hosted JavaScript file. Users kept bumping up against rough edges managing lots of disparate vals. What: A Val Town Project is a group of vals, files, and folders, versioned collectively. They support branches, forks, and merges. How: We made the sacrilegious decision to not build on git. We instead built a simplified system that works directly in our postgres database. Our dream is that…
