Wire shape verified against botocore for every operation we ship — request/response field names, types, error codes, HTTP status codes, headers, SigV4 scopes, ARN formats, eventstream framing. boto3, AWS CLI, CDK, Terraform, openai-python, anthropic-sdk-python — they can't tell us from AWS at the API boundary.
One container. One port. No JVM. No background daemons. Stdlib-only runtime. Heavy data planes (Kafka, Spark, LLMs) plug in by env-var passthrough to your own infra — we don't bundle what you don't need.
MIT. No "pro" tier, no feature gates, no telemetry, no upsell. If it works for you, ⭐ the repo is the only thanks needed.
