InputSourcePro

The application monitors the active window or visited URL and automatically changes the keyboard layout or input source to match the context, eliminating manual switching. It supports all macOS applications and popular browsers, allowing per‑app and per‑website configurations, and provides a minimal on‑screen indicator that shows the current input source when desired.

Additional features include smart punctuation that forces English punctuation in selected apps, a function‑key mode that toggles between standard function keys and media keys per application, and customizable shortcuts that can be triggered by single or combined modifier keys. Users can also define shortcuts for switching input sources directly.

Targeted at multilingual users and anyone who works with multiple keyboards, the tool offers fine‑grained control over input behavior while remaining lightweight and open‑source under GPL v3. It is distributed for macOS 11+ and can be installed via Homebrew.
