File & URL Repository MANager
a dual-pane file manager for macOS inspired by times when Dos Navigator was the king. furman is also Polish for "carter" — one who hauls goods by horse-drawn cart, and in our case, hauls files.
Features
Dual-pane layout with per-panel tabs — work in multiple directories at once
S3 cloud storage — connect to AWS, MinIO, Backblaze B2, Cloudflare R2, and 38+ providers
MCP server — standalone binary exposing S3 and SFTP tools for AI agents via Model Context Protocol
AI model inspector — instant metadata for SafeTensors, GGUF, and ONNX files (architecture, parameters, quantization, tensors) — header-only, works on 70 GB+ models
Archive browsing — navigate inside zip, rar, and 7z as if they were directories
View, edit, search — built-in viewer, editor, and file/content search
Drag & drop, quick filter, auto-refresh — everything you'd expect from a modern file manager
Dark & light themes — follows your OS, or toggle with a shortcut
Preferences — 20+ settings across General, Appearance, Network, and Terminal tabs
