OpenRouter sells access to 600+ models through one prepaid balance. Portkey is an AI gateway and control plane that sits in front of the provider credentials you connect, with plans sized by recorded logs. They overlap on routing and fallbacks, and differ on almost everything else.

OpenRouter vs Portkey at a glance

As of Oct 30, 2026OpenRouterPortkey
What it isA model marketplace and router: one account and one API for 600+ models from 80+ providers. [source]An AI gateway and control plane: universal API, routing, observability, guardrails, prompt management and an MCP gateway. [source]
APIOpenAI-compatible: change the base URL and model names to migrate. [source]OpenAI-compatible at https://api.portkey.ai/v1 with a Portkey API key; models are addressed as @provider_slug/model. [source]
How you payPrepaid credits; each request deducts its cost at the provider's list price. No markup on provider pricing. [source]Plans are sized by recorded logs per month. Going over the log limit does not affect requests; only logs beyond the limit are not recorded. [source]
Fees5.5% on credit purchases (Standard) or 8% (Business), charged when you buy credits, never per request. [source]Developer: free forever. Production: $49/month with 100k recorded logs, then $9 per extra 100k requests up to 3M. Enterprise: custom pricing. [source]
Bring your own keysBYOK on Standard and Business: $25,000 of list-price inference per month with no fee, then 5%. Not on the Free plan. [source]You connect your own provider credentials as integrations in the Model Catalog and call them through the gateway. [source]
Free tierFree plan: 25+ free models from 4 free providers, 50 requests/day. [source]Developer plan: free forever with 10k recorded logs per month, for prototyping and evaluation; Portkey says it is not suitable for production workloads. [source]
RoutingProvider routing with automatic fallback to other providers for the same model, optional fallback models, and an auto router (openrouter/auto) that adds no fee. [source]Fallbacks, conditional routing, load balancing, automatic retries, request timeouts and caching, configured in the gateway. [source]
GovernanceEnterprise plan with SSO (SAML), contractual SLAs, invoicing and dedicated support. [source]Production adds RBAC and service account keys. Enterprise adds SSO, granular budgets and rate limits, VPC hosting, private cloud and SOC2, GDPR and HIPAA compliance. [source]
Hosting and regionsEU and US in-region routing on Business and Enterprise (eu.openrouter.ai, us.openrouter.ai). [source]A self-hosted gateway you can deploy locally (universal API, retries, routing, guardrails, fallbacks, load balancing, basic dashboard), next to the hosted plans. [source]

When to pick OpenRouter

  • You want access to 600+ models from 80+ providers without opening an account with each one.
  • You want to pay for inference only, at the provider's list price, with no monthly platform plan.
  • You want free model variants to prototype on: the Free plan includes 25+ free models at 50 requests/day.

When to pick Portkey

  • You already have provider accounts and want guardrails, prompt management and observability in front of them.
  • You need RBAC, SSO, granular budgets and compliance such as SOC2 and HIPAA from the gateway.
  • You want to start with a self-hosted gateway and move to hosted plans later.

Where SentioGate fits

SentioGate is a lighter option if you mainly need routing over your own keys: a hosted BYOK router with 0% token markup and flat plans. Send model "auto" and it automatically falls back to another model if one fails. It has no MCP gateway or prompt management, so Portkey fits better when governance is the main requirement.

See SentioGate vs OpenRouter for the details, or the free community pool to try it without keys.

FAQ

Is Portkey an OpenRouter alternative?

They overlap on routing but solve different problems. OpenRouter is a marketplace: you buy credits and reach 600+ models from one account. Portkey is a gateway and control plane in front of your own provider credentials, with guardrails, observability and prompt management.

How much does Portkey cost compared with OpenRouter?

Portkey's Developer plan is free (10k recorded logs per month) and Production is $49/month; your providers bill inference separately. OpenRouter has no monthly plan: it bills inference at the provider's list price and charges 5.5% (Standard) or 8% (Business) on credit purchases.

Can I self-host either one?

Portkey has a self-hosted gateway you can deploy locally, next to its hosted plans. OpenRouter is a hosted service; its Enterprise plan adds SSO, contractual SLAs and invoicing.

Which handles fallbacks better?

Both handle them. OpenRouter falls back to other providers for the same model and to fallback models you list, and does not charge model tokens for attempts that error. Portkey configures fallbacks, retries, load balancing and conditional routing in the gateway, over the credentials you connect.
