Just found Web Harmonium — a free online harmonium you can play right in the browser.

No sign-up needed. It supports keyboard input, MIDI, Sargam + Western note labels, transpose, octave controls, reeds, and reverb.
Really nice for Indian classical practice, finding your tonic, or sketching melodies.
