Hey HN, we’re Robert, Din and Temirlan from Laminar (https://www.lmnr.ai), an open-source observability and analytics platform for complex LLM apps. It’s designed to be fast, reliable, and scalable. The stack is RabbitMQ for message queues, Postgres for storage, Clickhouse for analytics, Qdrant for semantic search - all powered by Rust. How is Laminar different from the swarm of other “LLM observability” platforms? On the observability part, we’re focused on handling full execution traces, not just LLM calls. We built a Rust ingestor for OpenTelemetry (Otel) spans with GenAI…

I've been working on this for some time now, starting with vm2, then deno-core for 2 years, and recently rewrote it on rusty_v8 with Claude's help. OpenWorkers lets you run untrusted JS in V8 isolates on your own infrastructure. Same DX as Cloudflare Workers, no vendor lock-in. What works today: fetch, KV, Postgres bindings, S3/R2, cron scheduling, crypto.subtle. Self-hosting is a single docker-compose file + Postgres. Would love feedback on the architecture and what feature you'd want next.

superlog▲497Hey HN, we’re Nico and Arseniy, co-founders of Superlog (https://superlog.sh). We're building a self-installing, self healing observability tool meant not to be opened. It has a wizard that daily sets up proper logging and an agent that investigates errors and opens PRs. Super short demo: https://www.youtube.com/watch?v=xFhU9Mk247M. In our earlier startups, we tried Sentry, Datadog, Grafana, Dash0, and nothing was good enough. Proper telemetry and alerting still requires a ton of manual setup. We struggled with adding good logs, so debugging was tough, especially as…

Hi HN, I'm a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs. Now I'm joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a…

Hi all, I am not an expert in nuclear energy but I've always wondered and found it difficult to get a clear picture about the amount of nuclear stations located in a specific region. So I built this tool that shows all the nuclear plants in the world, scaled by their capacity and with indication of their status. Clustering is enabled by default and allows to see the sum potential capacity of a region. It's a fun tool for me: e.g. disable clustering, scale circle radius to 70%, go to EU, and you'll see Germany has shutdown all of the stations. Ofc it's a widely known fact, but what came to my…

Hi, I am Krishna Thota. I am building an open source integration and data platform(https://cptn.io). The product is MIT licensed and the repo is at https://github.com/cptn-io/el-cptn. I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to…

I'm a software engineer who keeps getting pulled into DevOps no matter how hard I try to escape it. I recently moved into a Lead DevOps Engineer role writing tooling to automate a lot of the pain away. On my own time outside of work, I built Artifact Keeper — a self-hosted artifact registry that supports 45+ package formats. Security scanning, SSO, replication, WASM plugins — it's all in the MIT-licensed release. No enterprise tier. No feature gates. No surprise invoices. Your package managers — pip, npm, docker, cargo, helm, go, all of them — talk directly to it using their native…

Hi HN! I’m so excited to show my first open-source project and first post here. I initially started this project to learn Go language, it is an experimental project. The main goal is to track the adventure of a WebRTC stream from start to finish, by debugging the project or tracking the output at console. By trying out this project, you will deep dive into the steps which are taken while starting up a WebRTC session, and more. It consists of a web UI (TypeScript) and a server back-end (Golang) projects. They can run on Docker containers, in development mode or production mode, you can find…

Hey! This is an open source plasmid and vector (Short, often circular segments of DNA) editor, with features related to primer quality checks, PCR cloning, and protein analysis. I plan to add more restriction-enzyme-based features in the near future. It has some extras like a solution-mixing helper, automatic feature annotation. From a technical standpoint, this is a standalone binary written using the EGUI library in rust. A project goal is performance, with small memory footprint, and small application and file sizes. This is a continuous work-in-progress, and I'm open to any and all…

If you've built any web-based app in the last 15 years, you probably used something like Datadog, New Relic, Sentry, etc. to monitor and trace your app, right? Why should it be different when the app you're building happens to be using LLMs? So today we're open-sourcing OpenLLMetry-JS. It's an open protocol and SDK, based on OpenTelemetry, that provides traces and metrics for LLM JS/TS applications and can be connected to any of the 15+ tools that already support OpenTelemetry. Here's the repo: https://github.com/traceloop/openllmetry-js A few months ago we launched…
