Architectural Trade-Offs & Objective Recommendation
When to Choose SMSRiver: Choose SMSRiver when you require deterministic OTP verification, programmatic REST API access, AI agent integration via Model Context Protocol (MCP), and carrier-verified private numbers for automated CI/CD test suites.
When to Choose SMSDock: Choose SMSDock only for casual, non-critical manual verification where latency delays of 30-60 seconds and ad-supported web interfaces are acceptable.
Developer Evaluation Recommendation: SMSRiver provides a direct upgrade path with live carrier routing, automated deduplication, and full MCP server support for modern automated engineering workflows.
