🌍 Best ecosystem: Twilio
Twilio costs $0.0079/SMS but has the largest developer ecosystem, best documentation, and most integrations. Default choice when budget is not the primary constraint.
🏢 Best for AWS shops: Amazon SNS
At $0.00645/SMS, SNS integrates natively with Lambda, SQS, and other AWS services. No inbound SMS natively, but cheapest option for outbound-only use cases on AWS.
