Ask HN: What are you working on? (September 2026)
After being frustrated with outdated & inaccurate data Claude used when I was trying to do some property research, I thought it'd be cool to build an MCP that can provide accurate property data. Then it evolved into a full web app + an AI assistant.
This was also an excuse for me to try DuckDB in a real project. All the API endpoints are powered through in-process DuckDB querying parquet files stored in disk.
Description on the tin.
I found it hard to get fares and timetables for the Elizabeth Line in London between X and Y quickly hence I built this as an experiment using AI tooling.
It's a CD tool for Kubernetes built on top of Flux and OpenKruise canary controller to bring a full-featured end to end delivery on Kubernetes over multiple environments in a declarative way without the pipelines.
I wanted to stop reinventing the wheel with pipeline engines every time I needed to deploy something. Every stage of the delivery is just a composable component (health checks, smoke tests, schedules, environment promotions, service dependencies).
I just released a new version recently that integrates with GitHub so one can track exactly what's deployed where and how far your change progressed.
Browser extension for declarative web scraping. Mostly making it nicer to figure out CSS and XPath selectors thinking of some sort of REPL but I'd need to test the ergonomics. I want to reduce how often you need to use Inspect and the browser console.
Finishing up a PoC for a playwright based scraper that uses the same declarative config as the browser extension
Video proof of work for coding agents.
Agents upload a short recording of what they built, humans leave timestamped feedback, and the agent can retrieve that feedback and iterate.
Basically, instead of an agent telling you "done", it can show and you have a nice way to share the resulting videos in PR, on Slack, with your teammates etc.
Clusters ready to deploy you applications on. It is meant for companies who want their own private infra, but do not want to maintain it. It is multi cloud, with a focus on europe.
Our secret weapon is “Menno”: an assistant which helps you setting up the cluster and deploying applications. We use the assistant for handson demo’s and workshops and got some really good feedback on it.
The web spec is vast and endless, if you try to build something actually works for modern sites, it will be huge. If you want to keep it lightweight, it won't work for most sites.
Just use chrome-headless-shell or webkit. Don't reinvent the wheels.
