As a solo developer running my own app-based business, Telnyx has been a game-changer. I use their CPaaS platform mainly for SMS and voice features in my apps. The setup took a bit of effort at first, but once everything was in place, it ran smoothly and reliably. I appreciate the transparent pricing, the responsive support, and the level of control I get through their dashboard and APIs. It's helped me deliver a more professional and scalable product without needing to invest in heavy telecom infrastructure.
