Kosmoy vs TrueFoundry: Self-Hosted AI Platforms Compared (2026)

Each spoke is one capability, scored 0–10; the further a point sits from the centre, the stronger the product. TrueFoundry takes Gateway & Policy Control (9 vs 8) and Observability & FinOps (8 vs 7), ties Kosmoy on evals (4 apiece — neither ships an evaluation suite), and its documented air-gap install earns a 9 on sovereignty. Two caveats when reading it: the radar has no axis for model serving and fine-tuning, which is where much of TrueFoundry's value lives, and Kosmoy's advantage concentrates in the governance arc — inventory, security, containment and compliance.

The ML platform underneath. TrueFoundry serves models with vLLM, TGI and Triton — autoscaling, canary deploys, fine-tuning jobs, fractional GPUs via MIG and time-slicing — and its June 2026 Seldon AI acquisition unites predictive ML and agentic AI under one control plane. Kosmoy does not serve, train or fine-tune models at all; if the workload runs on your GPUs, TrueFoundry addresses a problem Kosmoy leaves to others.

Gateway breadth, externally validated. LLM, MCP and Agent gateways in one control plane, with declarative per-team/user/model rate limits and weight-, latency- and priority-based routing — recognized as a Representative Vendor in the Gartner Market Guide for AI Gateways (February 2026). Its MCP governance — a central registry, tool-level scoping through Virtual MCP Servers, per-user identity passthrough — is among the deepest documented.

Resilience engineering. TrueFailover (January 2026) adds degradation-aware, multi-model and multi-region automatic failover on top of the gateway (VentureBeat), alongside cost-velocity circuit breakers that trip an agent before it burns a budget. Kosmoy offers no comparable dedicated resilience module.

Self-service adoption. TrueFoundry publishes a free developer tier and self-serve plans on its pricing page; a single team can start without a procurement cycle. Kosmoy has no self-service tier.

Inventory beyond the gateway. TrueFoundry's registries — MCP servers, a 250+-model catalog — cover what is routed through TrueFoundry, and its own shadow-AI writing concedes that detection outside the gateway is hard; the aitori endpoint agent is a v0.1.0 open-source project (June 2026). Kosmoy's four registries reach further: connectors pull agents from Azure AI Foundry, Bedrock, Vertex, Salesforce and ServiceNow into one master list, each entry with an owner and a risk tier.

Compliance evidence. TrueFoundry documents SOC 2 Type 2 and HIPAA for itself — table stakes for a vendor — but no EU AI Act, ISO/IEC 42001 or NIST AI RMF mapping, evidence packs or governance reporting for its customers (not documented as of July 15, 2026). Kosmoy produces framework-ready evidence bundles from registry state plus gateway logs: one source, every audit.

Containment architecture. TrueFoundry's agent controls are genuinely good policy containment — per-agent identity, token and cost quotas, circuit breakers, instant revocation of a single tool without redeploying. Kosmoy's Action Capsule goes a layer deeper: each agent, MCP server or private model runs in a kernel-enforced sandbox whose only egress is its paired gateway, with per-task credentials and a kill switch. A hijacked agent reaches only what its gateway allows.

Sovereignty as the only mode. Both vendors do credible air-gap. The difference is categorical: TrueFoundry also operates SaaS and hybrid tiers with a managed control plane, while Kosmoy is only ever single-tenant software in your Kubernetes — there is no vendor-hosted control plane to trust in any configuration, which is why sovereignty is the one axis scored 10.

Both gateways are OpenAI-compatible, so applications move between them by changing a base URL, and the two platforms compose more naturally than they collide. A team serving fine-tuned models on TrueFoundry can register those systems in Kosmoy's inventory and route their production traffic through Kosmoy's gateway — the model platform and the governance platform each doing the job it was built for. The reverse split also works: TrueFoundry's gateway carries engineering traffic while Kosmoy remains the system of record that risk, security and audit teams query. What rarely makes sense is buying both for the same job; decide first whether your bottleneck is running AI or proving control over it — the gateway trends we track for 2026 suggest most enterprises eventually need an answer to both.
