Communications platform (CPaaS) for the UK

Bremlio is a UK communications platform for developers and businesses. Today it focuses on the two channels most teams need first — SMS and OTP/verification — over one simple, pay-as-you-go API.

CPaaS (Communications Platform as a Service) means delivering communications — messaging, verification and more — through APIs rather than fixed software. Bremlio (Bremlio Ltd, UK) is CPaaS-adjacent: it provides SMS and OTP/verification APIs today. It is not a full CPaaS — there is no voice or WhatsApp channel yet — and we'd rather be clear about that than overclaim.
