10 Best Agent Gateways for Self-Hosted Deployments 2026

Self-hosted agent gateways are presented as important for regulated or sensitive AI workloads because they keep traffic within an organization’s infrastructure while supporting centralized authentication, authorization, monitoring, and compliance controls. The comparison reviews ten products—MintMCP, Bifrost, Obot, TrueFoundry, NeuralTrust TrustGate, Solo.io agentgateway, LiteLLM, Kong AI Gateway, Apache APISIX, and Portkey—across deployment models, licensing, MCP support, performance, provider integration, and governance capabilities. Open-source Apache 2.0 and MIT licenses are common, although enterprise functions such as SSO, audit logging, and advanced security may be commercially gated. The products range from performance-focused gateways such as Bifrost to Kubernetes-oriented platforms such as Obot, TrueFoundry, and Solo.io, established API gateway extensions from Kong and APISIX, and broad model-routing platforms such as LiteLLM and Portkey. Selection should consider realistic workload benchmarks, STDIO and remote MCP transport support, OAuth and per-agent identity requirements, observability depth, operational capacity to run self-hosted infrastructure, and whether the gateway provides MCP-specific controls such as tool-level permissions, connector management, and policy-driven access.
