Comparez TrueFoundry à Portkey

La différence entre Portkey et TrueFoundry est que Portkey est une passerelle IA. Il achemine et surveille vos appels d'API vers des fournisseurs de modèles externes. TrueFoundry est une plateforme d'infrastructure d'IA complète. Oui, notre passerelle gère le routage comme le fait Portkey, mais nous gérons également le calcul proprement dit en dessous. Cela signifie que vous pouvez former des modèles, les affiner et les déployer sur votre propre infrastructure, et pas simplement acheminer le trafic vers l'API de quelqu'un d'autre.

If your AI requirements are stable and fit comfortably within Kong’s plugin model — external API routing, basic governance, and observability on top of your existing stack — extending Kong is a reasonable path. Where it gets complicated: AI-specific capabilities like MCP governance, semantic guardrails, and cost attribution at the self-hosted model level require enterprise licensing and specific plugin versions. And as your needs evolve toward self-hosted model deployment, agentic infrastructure, and full data sovereignty, Kong’s general-purpose architecture starts to work against you. TrueFoundry is worth evaluating as a purpose-built alternative before you’re locked into a plugin architecture that wasn’t designed for where AI infrastructure is heading.

TrueFoundry provides a purpose-built MCP governance surface: dedicated pre/post-tool guardrail hooks, Virtual MCP Servers, Cedar-based policy engine, inbound OAuth, and Secret Groups for credential isolation — all running inside your K8s cluster and production-ready today. Kong’s AI MCP Proxy, per-tool ACLs, and AI MCP OAuth2 give it a real native MCP control surface — and for existing Kong users, it’s incremental to add. The practical gap is complexity: Kong’s MCP implementation requires careful route topology management to keep direct MCP routes separate from LLM-side AI plugin flows. That’s a meaningful operational burden as your agentic workload complexity grows.

TrueFoundry runs the entire hot path — auth, rate limits, guardrails, PII/PHI detection, traces — inside your Kubernetes cluster with no external dependencies. Full sovereignty is the default architecture, not a configuration option. Kong has a strong data governance plugin catalog, but the most critical capabilities for regulated industries — bidirectional PII sanitization with restoration, advanced compliance controls — are enterprise license-gated and version-dependent. For teams where compliance is non-negotiable, that dependency on license tier is a risk worth pressure-testing early.

TrueFoundry is the only platform in this comparison explicitly documenting both gateway governance and execution lifecycle from one architecture. Guardrails fire at every point in the agent lifecycle — LLM input, LLM output, before a tool is called, and after it returns — and the split-plane design means the gateway governs traffic while async services handle durable, long-running loops. Kong’s AI MCP Proxy brings tool traffic into the plugin ecosystem without a separate governance plane, which is genuinely useful for existing Kong users. But there’s no native async execution substrate — long-running agent loops require application-side orchestration that your team builds and maintains separately.

TrueFoundry provides full-stack visibility out of the box: LLM request traces connected to GPU memory, pod health, and container logs in a single UI — no configuration required to get meaningful signal. Kong’s observability is genuinely powerful for teams already running its OTel/Prometheus/Grafana stack — LLM traffic joins the same pipeline as everything else. The tradeoff is setup: AI cost and token metrics require explicit plugin configuration to surface, and prompt body capture needs a deliberate redaction strategy before you see your first useful metric.

TrueFoundry offers the most GitOps-integrated prompt story: version history in the registry, compare/diff workflows, prompt version references enforced as CI gates, and dry-run/show-diff deployment previews. Prompt changes and infrastructure changes live in the same pipeline. Kong’s decK gives you a solid GitOps story for gateway configuration, and AI Prompt Decorator handles gateway-level prompt injection cleanly. The gap is prompt lifecycle depth: no versioning registry, no standalone playground, and no per-model prompt overrides. For teams doing active prompt iteration and needing CI-gated deployments, Kong’s tooling stops well short of what’s needed.

Kong’s open-source community is a genuine asset — years of production use, extensive plugin documentation, and a large ecosystem of operators who know it well. TrueFoundry competes on depth and focus: we’re built specifically for AI infrastructure, and our support model reflects that — 24×7 enterprise support via Slack and on-call engineers, a dedicated AM, and a G2 support rating of 9.9/10. Community support is valuable for API gateway operations. For production AI infrastructure with compliance requirements and SLA obligations, you want a team with direct accountability, not a forum thread.

TrueFoundry works well in a lightweight routing mode — you get unified monitoring across all providers, guardrails, and cost controls without requiring the full platform footprint. The more important question is where your AI stack is heading: cost pressures drive self-hosted models, compliance requirements demand full residency, and agentic use cases require MCP and agent governance. TrueFoundry is already built for that evolution. Teams that start with Kong for AI routing often face a more disruptive migration later when those needs emerge and Kong’s general-purpose architecture wasn’t designed to meet them.

Strong platform teams can absolutely make Kong work for AI. The plugin ecosystem is flexible and the operational model is well understood. The question is whether you want your best engineers spending cycles on plugin version management, AI feature compatibility testing, and building the orchestration layer that Kong doesn’t provide or on the AI products and models that actually create business value. TrueFoundry provides battle-tested automation for the infrastructure layer so strong teams can move faster, not slower.
