 Fairvisor vs. Kong See deployment pattern for Kong + Fairvisor The Situation Kong is a full API gateway platform. It is broad and powerful: routing, auth, plugins, transformations, and service mesh integrations.
Fairvisor is a drop-in LLM endpoint and enforcement layer: point your LLM clients at Fairvisor by changing the base URL — no SDK code changes — and get rate limits, budgets, loop detection, and policy-driven protection at very low latency.
Comparison Capability Fairvisor Kong Gateway Focus Drop-in LLM enforcement endpoint (no SDK changes) General-purpose API gateway Drop-in deployment Yes — change base URL + API key format, no SDK changes No (requires gateway/plugin configuration) AI-specific features Drop-in LLM endpoint, loop detection, token budgets, circuit breaker, streaming enforcement AI Gateway plugin (basic) Rate limiting Token bucket + cost-based + token-based (TPM/TPD) Token bucket, sliding window Cost control Budget enforcement with staged actions No Loop detection Built-in, configurable No Latency profile In-process decision path with low-latency targets Depends on gateway/plugin path and deployment model Deployment Edge-only or with SaaS Gateway + Konnect SaaS OSS Edge is fully OSS Community Edition (limited) Learning curve Policy-focused, narrow scope Full gateway with larger surface area When to Use Fairvisor You want LLM enforcement without touching application code — change the base URL, nothing else. You need loop detection, cost budgets, and staged enforcement actions. You want a focused, open-source tool with fast policy decisions. When to Use Kong You need a full API gateway with auth, transformations, plugins, and service mesh support. You want a broad platform for many gateway concerns beyond enforcement. Use Them Together Kong handles routing, auth, transformations, and gateway lifecycle. Fairvisor runs as the enforcement decision layer. You get platform breadth from Kong and AI-specific controls from Fairvisor. Need full gateway features and AI enforcement? See deployment pattern for Kong + Fairvisor
