LiteLLM vs Cloudflare AI Gateway (2026): AI Gateways Compared — and Where Kosmoy Fits
LiteLLM and Cloudflare AI Gateway sit at opposite ends of the same category — a self-hosted open-source proxy you own, and a free zero-ops edge proxy on a global network. Here is how they differ, and where each stops being a gateway question.
LiteLLM and Cloudflare AI Gateway both put one endpoint in front of many model providers, but they answer the question from opposite ends. LiteLLM is an open-source proxy (MIT, BerriAI) you self-host and own end to end, with deep spend attribution and an MCP gateway. Cloudflare AI Gateway is a proprietary edge service — free core, zero operations, running on Cloudflare's global network — with caching, dynamic routing, spend limits and Llama-Guard-based guardrails.
This page compares the two on the capability axes that matter, with every claim cited to each vendor's own documentation. It then does something a straight head-to-head cannot: it asks what happens when the requirement grows past the gateway — inventory, compliance evidence, agent containment — which is where a full AI management platform like Kosmoy enters the frame.
Who each product is for
LiteLLM
LiteLLM speaks to engineers who want to own the gateway: an MIT-licensed proxy and SDK fronting 100+ providers behind one OpenAI-compatible API, self-hosted anywhere including air-gapped, with spend tracking and budgets per org/team/project/key/tag, an MCP gateway with OAuth (including On-Behalf-Of), and a fast-moving community (~53.6k stars, weekly releases).
The enterprise tier is a license key applied to the same self-hosted deployment — SSO/SCIM, RBAC and audit logs, no data leaving the environment. The trade is that you run the infrastructure: Postgres, Redis, upgrades and on-call are yours.
Cloudflare AI Gateway
Cloudflare AI Gateway speaks to developers and platform teams building AI features — especially on Cloudflare Workers or already using Cloudflare — that want a free, low-friction proxy for caching, reliability, multi-provider routing and cost control. Core features (caching, rate limiting, fallbacks, automatic retries, dynamic routing, analytics, logging) are free on all plans; guardrails run Llama Guard 3 8B, and spend limits (June 2026) block requests over a dollar budget.
It runs exclusively on Cloudflare's global edge — there is no self-hosted, VPC, on-prem or air-gapped option, and Cloudflare documents AI Gateway as incompatible with its own Regional Services and Geo Key Manager, so all prompt/response traffic transits Cloudflare's network.
LiteLLM vs Cloudflare AI Gateway vs Kosmoy — the capability radar
Three shapes on the same ten axes. LiteLLM (violet) and Cloudflare AI Gateway (orange) both peak on Gateway & Policy Control, but they split on Deployment Sovereignty — LiteLLM near the top, Cloudflare near the bottom as a SaaS-only edge service. Both cluster low on the governance axes — the gateway category's signature. Kosmoy (blue) trades some raw gateway breadth for reach across inventory, compliance and agent containment. Read it as area: the two gateways compete on one spoke; the suite covers the web.

Where LiteLLM wins
Sovereignty and ownership. LiteLLM self-hosts anywhere, including air-gapped, with no data leaving your environment; Cloudflare AI Gateway is SaaS-only on the global edge and documented as incompatible with Cloudflare's own Regional Services and Geo Key Manager — decisive for EU data-residency or sovereignty-sensitive buyers.
FinOps depth. Budgets and spend attribution per org/team/project/key/tag, spend reports, Prometheus and OpenTelemetry v2 metrics, and Logs v2 with tool-call tracing go deeper than Cloudflare's cost analytics and dollar spend limits.
MCP and agent traffic governance. LiteLLM offers an MCP gateway with per-server access controls and OAuth, plus an A2A agent hub; Cloudflare AI Gateway documents no MCP traffic governance.
Where Cloudflare AI Gateway wins
Zero operations and price. Cloudflare's core gateway features are free on all plans with nothing to run — no Postgres, Redis, upgrades or on-call — where LiteLLM's core is free but you operate the infrastructure.
Global-edge scale and latency. Running on Cloudflare's network gives low-latency proximity to users and battle-tested scale (Cloudflare has documented scaling AI Gateway to billions of logs).
Turnkey routing, spend enforcement and vendor stability. Dashboard dynamic routing (A/B splits, if/else rules), fallback chains, automatic retries, enforced dollar spend limits by model/provider/metadata, and BYOK via Secrets Store — from a public company (NYSE: NET) with an adjacent AI-security portfolio.
Where Kosmoy fits
The specialist owns its spoke; the platform holds the frontier
Both LiteLLM and Cloudflare answer “how do we route and govern model traffic?” Neither answers “what AI are we running across the organization, is it compliant, and what happens when an agent misbehaves?” Those are different questions, and in a regulated enterprise they arrive together.
Kosmoy includes the gateway both products are — one OpenAI-compatible policy point with guardrails, RBAC, budgets and logging — but wraps it in the three layers a gateway leaves out: a risk-tiered inventory of every model, MCP server and agent (including a master agent registry that pulls from Foundry, Bedrock, Vertex, Salesforce and ServiceNow); EU AI Act, ISO 42001 (aligned) and NIST AI RMF evidence built from registry state plus gateway logs; and kernel-enforced Action Capsule containment for agents that act. Like LiteLLM, and unlike Cloudflare, it runs in your own infrastructure, including air-gapped.
So the honest framing is not “Kosmoy beats LiteLLM and Cloudflare at being a gateway” — they are capable gateways, and Cloudflare's free edge is genuinely convenient. It is that a gateway is one spoke. If the requirement is the whole web — inventory, gateway, compliance and containment in one self-hosted platform — that is a suite decision, not a gateway decision.

Which should you choose?
For a team whose problem genuinely is model traffic, pick on the axis that matters: LiteLLM to own it self-hosted with deep FinOps, Cloudflare AI Gateway for a free, zero-ops edge proxy — provided its SaaS-only deployment is acceptable for your data. Both expose OpenAI-compatible endpoints, so switching later is largely a base-URL change.
For an enterprise that has to prove control over all of its AI — not just route it — the choice is not between these two gateways but between a point tool and a suite. Kosmoy runs in your own infrastructure, so it also suits teams that ruled Cloudflare out on sovereignty grounds; some keep an open-source gateway for experimentation while Kosmoy holds the inventory, compliance evidence and containment for what reaches production.
Questions buyers ask
Is LiteLLM or Cloudflare AI Gateway better?
Neither is universally better. LiteLLM is a self-hosted, MIT-licensed proxy you own end to end, with deep FinOps and MCP governance, ideal when data must stay in your environment. Cloudflare AI Gateway is a free, zero-ops edge proxy with global scale, dynamic routing and spend limits, ideal for developers who want convenience over ownership. The deciding factor is usually sovereignty: if traffic cannot transit a third-party SaaS edge, Cloudflare is ruled out.
Can Cloudflare AI Gateway be self-hosted or run in my VPC?
No. Cloudflare AI Gateway runs exclusively on Cloudflare's global edge network; there is no self-hosted, customer-VPC, on-prem or air-gapped option, and Cloudflare documents it as incompatible with its own Regional Services and Geo Key Manager (Customer Metadata Boundary covers log metadata only). All prompt/response traffic transits Cloudflare. LiteLLM, by contrast, is self-hosted and explicitly air-gap capable.
Which is cheaper, LiteLLM or Cloudflare AI Gateway?
It depends on how you count. Cloudflare's core gateway features are free on all plans with no infrastructure to run, so the sticker cost is low; guardrails bill as Workers AI inference and log storage is tied to the Workers plan. LiteLLM's OSS core is also free, but you pay in operational cost — running Postgres/Redis, upgrades and on-call — and the enterprise tier is a paid license. For a small team wanting zero operations, Cloudflare is often cheaper in practice.
Do LiteLLM or Cloudflare AI Gateway handle EU AI Act compliance?
Not as products. Both provide logs that support a compliance program, but neither documents EU AI Act, ISO 42001 or NIST AI RMF evidence generation or AI risk classification as of July 15, 2026 — and Cloudflare's SaaS-only edge raises a separate data-residency question for EU buyers. That evidence layer is a governance-platform capability — Kosmoy generates it from its registries and gateway logs.
Where does Kosmoy fit against LiteLLM and Cloudflare AI Gateway?
Kosmoy includes the same OpenAI-compatible gateway both provide, but it is one layer of a full AI management platform: organization-wide inventory, compliance evidence, and kernel-enforced agent containment sit alongside it, all in your own infrastructure. If your requirement is only routing traffic, LiteLLM or Cloudflare is the lighter answer; if it is proving control over all your AI, that is a suite decision.
