Total cost, not headline price
Look at the platform fee charged on top of provider cost, whether it scales with commitment or with feature usage, and whether the provider price is passed through transparently.
Compare
Honest, sourced LLM gateway comparisons
Teams shortlist us against OpenRouter, Portkey, and Helicone. The comparisons below are line-by-line — pricing, platform fee, enterprise features, compliance — and every competitor claim cites a public page and a last-verified month. Written so you can drop them straight into an internal RFP.
Side-by-side
Three honest comparisons
Each page covers a sourced capability matrix, a feature-by-feature deep dive, pricing math, and the exact code change to switch — including where the competitor is genuinely ahead.
vs openrouter
NemoRouter vs OpenRouter
Public, individual-account LLM gateway.
Both route across providers with one managed key. We add 4 / 2 / 0% platform-fee tiers, built-in guardrails, role-based teams, SSO, and audit logs on every tier. OpenRouter has the broader catalog today — we say so.

NemoRouter vs Portkey
Observability-first gateway with tiered plans.
Both ship guardrails, prompts, and observability. We unlock every feature on every plan — no Enterprise-plan gate for SSO or audit logs — and run a fully-managed, no-BYOK provider-key model.
No feature gating · no BYOK · built-in billing
Read the comparisonvs helicone
NemoRouter vs Helicone
Observability proxy — logging + analytics.
Helicone is excellent at observability but it is not a routing gateway. We add multi-provider routing, guardrails, credit billing, and budgets — the observability is a genuine peer.

The four axes that decide an LLM gateway
Every /vs page is structured around these so a comparison reads as an RFP, not a sales deck.
What is included vs gated
Confirm which features (guardrails, prompt management, observability, SSO, audit logs, team controls) ship on the entry plan and which require an Enterprise contract.
Model & provider breadth
Count the models live today, not roadmap promises, and check how new providers get added — and who manages the provider credentials.
Compliance posture
Verify SOC 2 status (in progress vs certified), GDPR/DPA availability, data residency, and audit logging — and whether the vendor states it honestly.
How we compare
The accuracy contract
A comparison is only useful if it is checkable. Here is the standard every /vs page is held to.
Every competitor claim is sourced and dated
Each cell that says "Enterprise only", "plan-dependent", or "not published" links the specific public page it is drawn from and the month it was last verified (currently May 2026) — not a vague "as of 2026".
We never invent competitor pricing
Where a competitor does not publish a figure, the cell describes the pricing structure ("usage-based", "per-request fee") instead of quoting a number we cannot source.
We concede where a competitor is ahead
OpenRouter has a broader model catalog today; Helicone is a focused best-of-breed observability tool. The deep-dive sections say so plainly — an honest concession is more credible than a clean sweep.
Our own facts are precise
Every product feature — guardrails, prompt management, A/B tests, evals, observability, RBAC, SSO/SAML, audit logs, per-team budgets, and priority support — ships on every tier. Tiers differ on exactly two axes: the platform-fee percentage (4 % / 2 % / 0 %) and the RPM/TPM guarantee. Nothing else is gated.
