LLM Gateway Software
Alternatives to Bifrost
{"intro": "Bifrost gives teams an enterprise AI gateway and control plane for routing, governing, and securing LLM, MCP, and agent traffic. One OpenAI-compatible API connects to 20+ providers, with weighted load balancing, retries, automatic failover, and semantic caching. Virtual keys manage permissions, budgets, rate limits, and routing per consumer. Request monitoring, Prometheus metrics, OpenTelemetry tracing, MCP client and server support, and integrations for major SDKs round out the gateway. It runs through NPX, Docker, Kubernetes, or a Go binary, including self-hosted deployments.\n\nReaders may look elsewhere when Bifrost's provider count, deployment choices, or plan structure do not match their needs. Its OSS plan is free forever, while Enterprise uses custom pricing and includes a 14-day trial. Alternatives here range from general API gateways to products offering hundreds of models, broader protocol translation, image and video APIs, or Envoy-based agent traffic management. Weigh model and protocol coverage, routing behavior, governance, observability, MCP support, deployment platform, and total price before switching.", "rows": [{"ref": "sw:kong-gateway", "name": "Kong Gateway", "best_for": "Hybrid and multi-cloud microservice API management", "pricing": "Pricing on request; free plan and free trial", "key_difference": "Kong is a general open-source API gateway with extensive plugins and Kubernetes traffic management, rather than an AI-specific control plane.", "choose_when": "Choose it when hybrid or multi-cloud microservice deployment, declarative configuration, and custom gateway plugins matter more than Bifrost's AI governance."}, {"ref": "sw:llm-gateway", "name": "LLM Gateway", "best_for": "Broad model access with detailed spend analytics", "pricing": "Free plan; 30-day trial; provider costs paid directly with BYOK", "key_difference": "LLM Gateway reaches 250+ models from 40+ providers and tracks spend, tokens, latency, errors, and cache metrics.", "choose_when": "Choose it when a larger model catalog, BYOK without platform fees, or integrations such as Cursor and VS Code outweighs Bifrost's MCP controls."}, {"ref": "sw:yolorouter", "name": "YoloRouter", "best_for": "Protocol translation and media-capable AI routing", "pricing": "Free plan", "key_difference": "YoloRouter translates OpenAI, Anthropic, and Gemini protocols and adds image and video APIs alongside routing and access controls.", "choose_when": "Choose it when clients need mixed protocol compatibility, delivered image or video billing, or upstream key pooling beyond Bifrost's gateway."}, {"ref": "sw:requesty", "name": "Requesty", "best_for": "Large model catalog with policy and PII governance", "pricing": "Free plan", "key_difference": "Requesty offers access to 600+ models with regional and policy routing, PII scrubbing, guardrails, and team-level analytics.", "choose_when": "Choose it when broad model choice, regional routing, PII handling, or integrations such as Codex and OpenWebUI are priorities."}, {"ref": "sw:truefoundry-ai-gateway", "name": "TrueFoundry AI Gateway", "best_for": "Enterprise model coverage and MCP tool governance", "pricing": "Free plan; paid from $25/user/mo", "key_difference": "TrueFoundry connects 1,000+ LLMs across 35+ platforms and combines quotas, logs, RBAC, and governed Slack, GitHub, and other tools.", "choose_when": "Choose it when very broad provider coverage, centrally stored request logs, or OAuth2-protected MCP integrations suit your organization better."}, {"ref": "sw:wso2-ai-gateway", "name": "WSO2 AI Gateway", "best_for": "Prompt controls, guardrails, and semantic caching", "pricing": "30-day trial; paid; free plan", "key_difference": "WSO2 emphasizes prompt templates, semantic checks, PII masking, schema validation, and API-to-MCP exposure alongside AI gateway controls.", "choose_when": "Choose it when built-in prompt management, detailed content guardrails, or subscription-level API controls are more important than Bifrost's provider breadth."}, {"ref": "sw:envoy-ai-gateway", "name": "Envoy AI Gateway", "best_for": "Open-source Envoy-based AI and agent traffic control", "pricing": "Free plan", "key_difference": "Envoy AI Gateway uses Envoy for model virtualization, inference routing, MCP multiplexing, OAuth, quotas, and usage-based rate limits.", "choose_when": "Choose it when an open-source, Envoy-native control plane and inference load balancing fit your self-hosted stack better than Bifrost."}]}
