TrueFoundry AI Gateway vs Apache APISIX AI Gateway

The question that decides it: Do you want a free foundation project you operate entirely yourself, or a paid platform with a vendor and an audit report behind it?

Our verdict

Free, permissive and already part of your API stack, with basic LLM proxying being enough: Apache APISIX AI Gateway. You need a SOC 2 report, a GDPR agreement, air-gapped support and 27 providers working out of the box, and you have budget: TrueFoundry AI Gateway.

Why

Both of these end up running inside your own infrastructure, so the deployment field does not separate them. What separates them is whether there is a vendor on the other end of the phone, and what that costs.

Apache APISIX AI Gateway is free in the strongest sense: the entire project is Apache-2.0 with a zero token markup, no credit fee and no seat fee, and its AI proxy plugins are part of that. Because it is a foundation project rather than a vendor, it publishes no SOC 2 report, no HIPAA position, no GDPR agreement and no air-gapped position — those are not gaps in our research, they are things a project of that shape does not issue. Its documented reach is 10 to 20 upstream providers, and it publishes no total model count. Zero data retention is recorded as not applicable, because prompts never reach a vendor at all.

TrueFoundry is the inverse trade. It is proprietary and sold on request tiers, and in exchange it publishes a SOC 2 report and a GDPR data processing agreement, supports air-gapped installation, and states 1,000 models across 27 upstream providers. If your reason for self-hosting is a compliance requirement rather than a cost one, that combination is the point: you get the isolation of running it yourself and an audit report to show a reviewer, which APISIX cannot give you.

The honest framing is that these are answers to different questions. Adopting APISIX purely for LLM routing is usually the wrong call — its value comes from already running it for ordinary API traffic and wanting AI requests governed by the same data plane. Adopting TrueFoundry is a platform decision with a budget attached. If neither of those describes you, the pair to look at is a self-hostable LLM-native gateway such as LiteLLM or Bifrost, which sit between these two on both cost and feature depth.

Which one, concretely

Choose TrueFoundry AI Gateway if

  • You need a published SOC 2 report and a GDPR data processing agreement
  • You need vendor-supported air-gapped installation
  • You want 1,000 models across 27 providers working without integration work
  • You want a vendor accountable for fixes and support

Choose Apache APISIX AI Gateway if

  • You already run APISIX for ordinary API traffic and want one data plane
  • You want a genuinely free Apache-2.0 stack with no vendor account
  • Basic multi-provider proxying and token rate limits are enough
  • You want prompts never to reach any vendor at all

Common questions

Is Apache APISIX enough to use as an AI gateway?

For basic multi-provider proxying and token rate limiting on an APISIX deployment you already run, yes. Its documented reach is 10 to 20 upstream providers and it publishes no total model count, so it is not a substitute for an LLM-native gateway if breadth or AI-specific features are what you need.

Why pay for TrueFoundry when APISIX is free?

For the paperwork and the reach. TrueFoundry publishes a SOC 2 report and a GDPR data processing agreement, supports air-gapped installation with a vendor behind it, and states 1,000 models across 27 providers. APISIX issues none of those documents, because it is a foundation project rather than a vendor.

Do prompts leave my network with either one?

Not to the gateway vendor. APISIX records zero data retention as not applicable precisely because it runs inside your own infrastructure and prompts never reach a vendor. TrueFoundry can also run in your own cloud or air-gapped. In both cases prompts still reach whichever model providers you route to.
