Signal?

Thanks! Agreed — it’s just up to Signal to offer a sharing endpoint for the web to make it fully possible.

This is a longstanding feature request for Signal:

AddToAny will certainly include a Signal share button as soon as Signal offers a sharing endpoint for the web.

In the meantime, folks can use AddToAny’s universal button to share to the Signal app on Android & iOS.
