The models' case: The deepest event-source ecosystem in serverless — native triggers from EventBridge, SQS, SNS, Kinesis, DynamoDB Streams, S3, and API Gateway, with mature TypeScript. The models' main caveat: Operational surface area — IAM, VPC, cold starts, and the sprawl of glue services make it heavy for small teams who just want to ship an API without. The strongest alternative is Cloudflare Workers — TypeScript-first edge runtime, excellent latency and value, with integrated Queues, Workflows, cron, storage, durable state, retries, and. Not unanimous: ChatGPT picks Cloudflare Workers.
