The capability matrix
Both gateways serve OpenAI-compatible APIs. The differences are pricing philosophy, feature gating, and provider-key ownership. Every marker is sourced below.

Sources & methodology
Competitor rows reflect each vendor's publicly documented plans and docs as last checked in June 2026; each cell links the specific source. Where a competitor's pricing or plan structure is not public, the cell describes the structure rather than quoting a figure — we never invent competitor pricing. Found something out of date? Email sales@nemorouter.ai and we'll correct it.
- Portkey publishes a usage-based / per-request gateway price with paid plans layered above a free tier. The fee structure is documented; specific figures are not quoted here because they vary by plan. Portkey pricing tiers · Portkey pricing page · verified June 2026
- Portkey operates on a bring-your-own-key model: you provision, rotate, and audit each provider credential. Virtual keys abstract usage but the underlying provider accounts remain yours. Portkey (all plans) · Portkey docs — virtual keys · verified June 2026
- Portkey documents guardrails as a product capability; availability of specific guardrail checks and the volume allowance vary by plan tier. Treat the cell as "available, plan-dependent" rather than "free". Portkey Pro / Enterprise · Portkey docs — guardrails · verified June 2026
- Portkey documents SSO/SAML, advanced RBAC, and audit logging as Enterprise-plan capabilities rather than features available on the free or entry paid plan. Portkey Enterprise · Portkey pricing — Enterprise plan · verified June 2026
- Portkey provides usage analytics and cost observability. It does not ship a built-in customer billing / credit ledger — teams wire up billing themselves. Portkey (all plans) · Portkey docs · verified June 2026
- Portkey publishes uptime targets for its paid/enterprise plans. A contractual SLA percentage is associated with higher tiers rather than the free plan. Portkey Enterprise · Portkey site · verified June 2026
- Nemo platform fee is charged on top of provider cost, never deducted from purchased credits. Every product feature ships on every tier — tiers differ only on fee percentage and RPM/TPM guarantee. Nemo Router pricing · Nemo Router pricing page · verified June 2026
Credits are the product, not an afterthought
Nemo Router is built around a Stripe-integrated credit ledger with atomic reserve-and-settle. Every API call deducts in real time, every failure releases the reservation, and budgets are enforced before a request leaves the gateway. Portkey has no built-in billing — you wire up cost tracking yourself.
- Atomic reserve+settle ledger
- Per-key / per-team / per-org budgets
- Auto-topup + 402 error path
Step 01 — pre-flight
Reserve
Credits reserved atomically before the request leaves — budget caps enforced here, not after the fact.
Step 02 — request path
Forward
The call routes to the provider with guardrails applied. Every failure path releases the reservation.
Step 03 — settle
Settle
Actual provider cost settles against the reservation in real time — per key, per team, per org.
Frequently asked questions
Common questions about switching from Portkey to Nemo Router.
Is Nemo Router cheaper than Portkey?
It depends on which features you need. Portkey gates advanced governance (SSO, audit logs, advanced RBAC) to its Enterprise plan; Nemo Router includes them on every tier. Nemo Router charges 4% pay-as-you-go, 2% on Tier 2 monthly ($100+/mo), 0% on Tier 3 annual ($1,200+/yr). Always on top of provider cost, never deducted from credits. We do not quote Portkey's figures; see the sourced footnotes under the comparison table.
Can I switch from Portkey to Nemo Router?
Yes. Both Nemo Router and Portkey use the OpenAI-compatible API format. Change your base URL to https://api.nemorouter.ai/v1 and swap your API key — you can also drop Portkey's virtual-key headers. Migration takes under five minutes.
Does Nemo Router have observability like Portkey?
Yes — and it is genuine common ground. Nemo Router includes real-time request logging, cost tracking per model/team/key, latency percentiles, error-rate monitoring, and callbacks to Langfuse, Datadog, S3, and Slack. The difference is Nemo Router does not tier observability — it is included on every plan.
What does Nemo Router have that Portkey does not?
A Stripe-backed credit billing system with atomic reserve-and-settle, per-team and per-key budget caps enforced in the request path, and a fully-managed (no BYOK) provider-key model. Nemo Router also includes SSO/SAML and audit logs on every tier, where Portkey documents them on its Enterprise plan.
Are all Nemo Router features really included on every tier?
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.
How current is this comparison?
Every Portkey row links the specific public page it is drawn from and a last-verified month (currently June 2026). Where Portkey's pricing or plan structure is not public, the cell describes the structure instead of quoting a figure — we never invent competitor pricing.
No BYOK · 5-minute migration
Why sign five contracts when one key runs them all?
Nemo Router replaces separate provider contracts, invoices, and rate limits — one OpenAI-compatible key for 78+ models, on a single bill. Less procurement, more shipping.
