    Hain

    Hain

    An 'alt+space' launcher for Windows, built with Electron

    An alt+space launcher for Windows, built with Electron. I always dreamed of an alternative to Alfred on Windows, that is made with JavaScript. so, I made it. It's a launcher with strict syntax (like terminal programs), it's not targeting to interpret natural language. I believe strict syntax can provide a more powerful and fast response than interpreting natural language. Searching Executable files very fast with Fuzzy Matching. Plugins in Pure JavaScript. I always dreamed of an alternative to Alfred on Windows, that is made with JavaScript.
