Arqen, an open-source AI assistant with a Mission Control for agents, is the flagship — but the same instinct runs through everything below it: keep it private, keep it self-hosted, keep it running on hardware I actually control.
A Windows AI assistant with a Mission Control for agents. Tasks, workflows and schedules run in the background, each agent gets exactly the tools it needs — files, web, GitHub, Google, MCP — and anything that can't be undone waits for my approval. Open source, in English and Swedish.
github.com/stefansemb/Arqen ↗An open-world pirate survival game — procedural river systems, an archipelago built in World Partition, and a slow, deliberate build.
A local-first AI assistant that runs Ollama, GPT, and Claude side by side in one interface — with real file tools it can only use after I've approved the exact change.
The self-hosted server everything else runs on — media, automation, and a handful of always-on services I maintain myself.
A small collection of focused web tools for creators. First up: YouTube thumbnails in your channel's own style — background removal runs right in the browser, so your photos never leave your device.
samidatools.com ↗I'm Stefan. I build software that runs on hardware I actually own — usually late in the evening, with more terminal tabs open than I'd like to admit.
Local-first isn't really a philosophy for me so much as a preference: I'd rather host something myself and understand exactly how it works than hand it to someone else's server. Arqen is where that preference gets applied most literally — everything else on this page shares the same instinct.
