Mirrorfly

MirrorFly is a chat and calling API for teams building messaging into their own products, and its differentiator is deployment rather than features: it offers self-hosting with complete source-code access, which is what buyers with data-residency or sovereignty requirements are usually looking for. The API spans in-app chat, HD video, voice and SIP/VoIP calling, with a multi-tenant server for running several business apps from one deployment. More recently it has extended into AI agents embedded inside those chat workflows. The trade-offs are the usual ones for self-hosted infrastructure, plus one specific to this product: pricing is not published, and at the time of review the pricing page returned a not-found error, so cost discovery means contacting the company.
