Adaline Gateway is a production-grade SDK that abstracts away the complexity of calling multiple LLM providers through a single, strongly-typed interface. It supports providers including OpenAI, Anthropic, Google, AWS Bedrock, and xAI. Built-in features include batching, automatic retries with exponential backoff, caching via plugins, OpenTelemetry instrumentation, and extensible custom provider support. It runs 100% locally and is not a proxy, making it suitable for enterprises requiring privacy and self-hosting.
