🌟 About

kleinbem.dev houses production-grade, open-source software tools and runtime platforms developed by Martin Kleinberger. Each project here originated from real-world infrastructure, local AI orchestration, or developer workflows, engineered into reusable, standalone open-source products.

📦 Standalone Products & Projects

Project	Tech Stack	Highlights
cadre	Nix · Python · Ollama · Mesh-LLM	Private AI teammates on your own compute. Autonomous developer agents running on local hardware inference via Goose and custom execution runtimes.
revue	Rust · Svelte · Tailwind · Ollama	Nix-native AI PR code review engine. Automated code reviewer with smart multi-tier model fallback (Ollama, Claude, Gemini) and Forgejo/GitHub support.
attic-ui	SvelteKit · TypeScript · Tailwind	Modern web interface & store inspector for Attic. Next-generation management portal for self-hosted Nix binary caches.
nix-gantry	NixOS · systemd-nspawn · Bash	Zero-eval atomic container deployment. Builds containers once in CI; target hosts fetch manifests and swap them atomically without local evaluation.
nix-detour	Nix · Svelte · Nixpkgs	Surgical Nixpkgs package detention. Safely hold back broken packages from nixos-unstable or inject open PR fixes until upstream merges.
foyer	SvelteKit · Tailwind · NixOS	Next-gen homelab portal & service launchpad. Lightweight, reactive application dashboard for multi-node self-hosted platforms.

📐 Engineering Values

• Reproducibility First: Built strictly on declarative infrastructure (Nix Flakes, OpenTofu, hermetic builds).
• Local-First & Privacy-Conscious: AI tools engineered for local, hardware-accelerated compute (CUDA, ROCm, Vulkan, Apple Silicon, Jetson).
• High Performance: Core systems and runtimes implemented in Rust; interfaces crafted with modern Svelte 5 / SvelteKit for near-instant reactivity.
• Strict Quality Control: Every repo runs declarative branch protection, sign-off rules, CodeRabbit automated reviews, and CI test pipelines.
