Choose OpenRouter for catalog reach.
It is the direct fit when broad hosted model access and provider aggregation outweigh ownership of the operating boundary.
2026 gateway buyer guide · reviewed August 29
OpenRouter vs. LiteLLM vs. AI Gateway HQ
These are three different operating decisions: buy model access from a hosted marketplace, operate an open-source proxy, or use a managed financial and governance boundary. Compare the responsibility—not just the provider count.

- No synthetic winner score
The short answer
Choose the operating model your team can defend.
Provider count, proxy latency, security ownership, financial enforcement, and cross-company reporting are separate requirements. No single score can collapse them honestly.
Choose LiteLLM for source control.
It is the direct fit when the engineering team wants to customize and operate the proxy, database, master key, upgrades, and availability model.
Choose AI Gateway HQ for accountable control.
It is the direct fit when finance, security, platform operations, and portfolio oversight need one pre-dispatch decision and evidence model.
Side-by-side evidence
Compare the boundary, burden, and bill.
Public meters are not normalized: hosted inference fees, successful gateway requests, infrastructure, support, and enterprise capacity are different units.
Decision areaAI Gateway HQOpenRouterLiteLLM
Operating model
Managed gateway and control plane with isolated company workspaces, prepaid managed inference, and customer-owned provider accounts.
Hosted model marketplace and unified API. OpenRouter operates the provider aggregation layer.
Open-source proxy and SDK, with paid enterprise options. The deploying team owns or contracts for the operating stack.
Best fit
Companies that need finance, security, platform, and portfolio controls to operate as one accountable boundary.
Teams prioritizing immediate access to a broad hosted model and provider marketplace.
Engineering teams prioritizing source access, customization, or a proxy they operate themselves.
Routing and continuity
Capability, policy, budget, health, quota, capacity, priority, weight, request cost, and bounded failover narrow every eligible target before dispatch.
Provider controls, routing modes, fallbacks, and marketplace-informed model routing within its hosted service.
Broad adapters, retries, fallbacks, load balancing, and routing modes configured in the deployed proxy.
Spend boundary
Strict organization and workload exposure is atomically reserved before a provider call. Managed requests also require purchased cash and stop at zero eligible balance.
Budgets are checked before routing; reviewed documentation warns that in-flight requests can overshoot and that BYOK spend is excluded.
Virtual-key and team budgets, rate limits, and spend tracking use the proxy's configured database and cost data.
Public price model
No-card Test Lab; Flex is $0.10 per 1,000 successful requests; customer-owned provider inference has no percentage markup.
Pay-as-you-go lists a 5.5% fee. Its pricing page separately describes the current BYOK allowance and fee threshold.
Open-source software is $0; infrastructure and operation remain with the deployer. Enterprise pricing is custom.
Governance evidence
Workload identity, Observe/Shadow/Enforce policy, hard limits, local attack signals, reason-coded attempts, and hash-chain audit evidence; prompt bodies are off by default.
Workspace, key, budget, routing, activity, analytics, guardrail, and enterprise identity capabilities in the hosted product.
Proxy logging, virtual keys, guardrails, and paid enterprise identity and audit capabilities within the customer's chosen deployment model.
Company and portfolio reporting
Separately approved operating, finance, and business-outcome scopes connect gateway evidence to company-owned KPIs or OKRs without pooling provider secrets or prompt bodies.
Workspace analytics and request activity; the reviewed public material does not document the same company-consented private-equity hierarchy.
Team and customer spend attribution; portfolio-company consent and business-outcome reporting require a separate operating layer.
