tl;dr: OpenLogi is a local-first, Rust-based alternative to Logitech Options+ that talks directly to Logitech mice over HID++ to remap buttons, control DPI, and configure SmartShift, with no account or telemetry. Bindings live in a plain TOML config file, and it supports Bolt, Unifying, Lightspeed, Bluetooth, and wired connections across signed macOS, Linux, and Windows builds. Per-app profiles, Options+ import, and Flow-style cross-machine features are on the roadmap; users must quit Options+ (or Solaar on Linux) to avoid HID++ conflicts.
