Building Kiln: A Self-Hosted App Builder That Never Leaves Your Infrastructure

Lovable, v0, Bolt: they all nailed the same loop. You describe an app in chat, an agent writes the code, and a live preview updates while you watch. It feels like magic the first time. Then you try to use it for something real at work and hit the wall: your prompts, your source, and your data all live on someone else’s cloud. For a lot of internal tools that’s a non-starter. The prototype a PM wants to spin up touches customer records. The dashboard someone needs by Friday runs against a production-adjacent database. You can’t paste that into a SaaS build tool and hope for the best. ...

Building HiveLabs: Taking the AI Agent Team Concept to Production

A couple of weeks ago I wrote about 4shClaw, a personal multi-agent AI assistant running with Docker. It works. Agents spin up in containers, coordinate through a shared ledger, and build a game called GLORP autonomously. The architecture proved out the core ideas: container isolation, declarative capabilities, ephemeral agents, lead-agent orchestration. But 4shClaw is a personal tool. Single user, SQLite, filesystem IPC, Node.js host. That’s fine for me. It’s not fine for a team of five engineers at a fintech company who want the same thing on their infrastructure, with audit trails their compliance team will accept. ...

From Kubernetes to Gitlab-ci in less than 10min

I have been playing a lot with Kubernetes lately, from creating a cluster from scratch on bare metal, setting up a ELK stack, Prometheus metrics to setting up a CI/CD using Gitlab CI. I found the last one so easy that I made a video for it. I have been using a DigitalOcean Kubernetes cluster for this video, it was super easy and I got $100 to play with it for 60 days. ...
