As answered by people managing ChatDOC and SMSCode.gg.
SMSCode.gg's answer:
SMSCode combines the lowest pricing in the market (from $0.0044/activation) with coverage across 200+ countries and a developer-friendly REST API — all wrapped in a clean, minimal UI. No bloat, no subscription, pay only for what you use.
SMSCode.gg's answer:
SMSCode offers better pricing, wider country coverage, and a cleaner API compared to most alternatives. With 100,000+ active users and instant OTP delivery, it's reliable for both individual use and bulk automation workflows.
SMSCode.gg's answer:
Developers integrating SMS verification via API, individuals protecting their privacy online, businesses and resellers running bulk SMS verification operations, and SMM panel operators.
SMSCode.gg's answer:
SMSCode was built to solve a simple frustration — existing SMS verification services were slow, overpriced, and had terrible APIs. We built a clean, fast alternative from the ground up with a focus on reliability and developer experience.
SMSCode.gg's answer:
Rust (Axum), PostgreSQL, Redis, deployed on bare metal infrastructure for maximum performance and reliability.
