Honest comparison
KeyForge vs Kong AI Gateway
Kong is a battle-tested API gateway, and its AI Gateway adds plugins for routing, rate limiting, and governance across LLM providers. KeyForge is a security gateway purpose-built for autonomous agents. Kong excels at operating API traffic at infrastructure scale; KeyForge is built around the agent as the unit of security and spend.
Where Kong AI Gateway is strong
Proven gateway at scale
Kong is a mature, high-performance API gateway with a huge plugin ecosystem, deployable self-hosted or managed, trusted for large production API estates.
AI routing & governance plugins
Multi-LLM routing, prompt templates, request/response transformation, and rate limiting via configurable plugins that slot into existing Kong deployments.
Unified with your API layer
If Kong already fronts your APIs, the AI Gateway extends the same policies, auth, and observability to LLM traffic without introducing a new operational surface.
Where KeyForge wins
Agent-native, not infra-native
Kong governs traffic and consumers at the API-infrastructure level. KeyForge is built around the agent: each vk_ virtual key carries its own budget, model allow-list, expiry, and audit scope, no plugin assembly required.
Real credential abstraction
Rate-limiting an LLM route does not stop the agent from holding the real provider key. KeyForge injects the real credential server-side; the agent only ever sees a vk_ token worth exactly its remaining quota.
Hard dollar caps, not just rate limits
Kong rate-limits request frequency. That does not stop a single expensive runaway loop from draining your provider account. KeyForge enforces per-key dollar caps, spend stops at the number you set.
HMAC tamper-evident audit chain
Kong produces logs and analytics; KeyForge produces cryptographic proof. Every request is hash-chained to the previous one, verifiable on demand and shareable as a signed report.
Feature comparison
| Capability | Kong AI Gateway | KeyForge |
|---|---|---|
| Primary design | API gateway + AI plugins | Agent-native security gateway |
| Setup model | Deploy + configure plugins | Base-URL + key swap |
| Credential handling | Agent typically holds real key | vk_ abstraction, real key never exposed |
| Spend control | Request rate limiting | Hard per-key dollar caps |
| Audit integrity | Logs & analytics | HMAC hash-chained, verify + export |
| 429 handling | Rate-limit + retry plugins | Key-pool auto-shuffle, same model |
