September 9, 2026LiteLLM is the known option. agentgateway is the open one.
When enterprises build AI agent platforms, selecting the right gateway is critical for routing models, models tools (like MCP servers), and securing traffic. While LiteLLM is widely recognized for its extensive provider catalog and unified OpenAI-compatible API, it often falls short in enterprise evaluations because crucial security and platform controls—such as SSO beyond five users, secret manager integrations, scoped guardrails, and audit logging—are locked behind a proprietary enterprise license. Conversely, agentgateway (an Apache 2.0 open-source project hosted by the Linux Foundation) serves as a robust, general-purpose data plane for HTTP, gRPC, and LLM traffic, providing enterprise-grade security features without embedded license gates. Furthermore, agentgateway boasts a stronger public security record, avoiding the critical vulnerabilities that have plagued LiteLLM. For teams that need a true microservice gateway for AI services rather than just an expansive SDK, agentgateway presents a more secure, open, and scalable architectural choice.
