Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Fenster is a CLI tool and OpenAI-compatible server that exposes Google Chrome's built-in Gemini Nano LLM for local, on-device inference without API keys or cloud dependencies. It's interesting because it repurposes a browser-based model into a Unix-friendly tool with pipe support, file attachments, and a REPL, bridging a gap for private AI workflows.

Target audience: backend devs, devops, ai engineers
