OpenRouter vs Portkey: Rent Model Access or Run a Governed Gateway?

What SRVpress, TU Vienna, Glama and a platform on Portkey cloud report about each, then fees, data handling, controls and one workload priced. OpenRouter sells 500+ models with a fee on credits; Portkey, now Palo Alto Networks' Prisma AIRS AI Gateway, meters recorded logs on your own keys.

GILD verdict

Pick OpenRouter when you want to buy access to hundreds of models through one balance and can test the hosts behind each production model.

Speed and errors are why SRVpress left. Portkey is the better choice when traffic must reach the model makers on your own keys and security needs recorded logs, audit logs, and a data plane in your VPC. At the 1,000,000-request workload above, Portkey's Production plan adds about US$130 a month against about US$495 in OpenRouter Standard fees, and OpenRouter's BYOK path adds nothing under US$25,000 of monthly inference. On Portkey's hosted cloud, put a canary and a hit-rate alert on cache changes: one change took a production platform down in 2025.

Team accounts split along the two products' failure modes. A production platform went down on July 23, 2025 when a caching change on Portkey's hosted cloud reached every app behind it, and a TU Vienna team turned Portkey down because SSO, organization management and self-hosting sat behind enterprise plans. On OpenRouter, SRVpress left over slowness and errors in October 2026. OpenRouter sells model access, and Portkey governs the model access you hold on your own keys. OpenRouter bills 500+ models at list price from prepaid credits and charges a fee on each purchase. Portkey calls the model makers on your own keys, records each request, and meters those recorded logs. Palo Alto Networks closed its purchase of Portkey on May 29, 2026 and sells it as Prisma AIRS AI Gateway; Stripe agreed on August 19, 2026 to acquire OpenRouter, and the deal had not closed by October 28, 2026.

What teams report

Failures and incidents 1

  1. A platform on Portkey cloudOn Portkey

    On July 23, 2025 a Portkey caching change on Portkey's hosted cloud made one platform's simple cache match similar requests, the hit rate neared 100% and the whole platform went down until Portkey reverted the change the same day.

    “This caused a complete platform failure while all customers were actively using the system.”
    Leonardo Marciano, CTO, as his GitHub profile describes himself, A platform on Portkey cloudGitHub (Portkey-AI/gateway), , post

Left or turned down 2

  1. SRVpressOn OpenRouter

    SRVpress said it stopped using OpenRouter, citing slowness and errors (X, Oct 25, 2026).

    “Stopped using OpenRouter for same reason, slowness & errors.”
    Jay Brunet, System Admin and Developer, SRVpressX, , post

  2. TU ViennaOn Portkey

    A small TU Vienna team looked at LiteLLM, Portkey and Kong, found SSO, organization management, observability or self-hosting behind enterprise plans on each, and built its own gateway (Hacker News, Jul 1, 2025).

    “Every AI gateway we looked at (LiteLLM, Portkey, Kong, etc.) locked critical features like SSO, organization management, observability, or self-hosting behind enterprise plans.”
    meffmadd, Member of a TU Vienna team serving an OpenAI-compatible API to researchers, TU ViennaHacker News, , post

  1. GlamaOn Portkey

    Glama's founder pointed Portkey users to Lightport, an actively maintained fork of Portkey's gateway (GitHub, Jul 18, 2026).

  2. kisamoto, Author of braw.devOn OpenRouter

    The author moved a US$100 monthly Claude plan to US$10 for Zed and a US$90 OpenRouter top-up in April 2026, then corrected the post to say OpenRouter charges a 5.5% fee (braw.dev, Apr 6, 2026).

    “OpenRouter does charge a 5.5% fee.”

Adopted 1

  1. Garblesnarff, Maintainer of Infinite RealmsOn OpenRouter

    The maintainer of the Infinite Realms app routes its production game-master model through OpenRouter with a fallback list; an October 14, 2026 audit found implicit prompt caching hitting about 1% and added explicit cache breakpoints, which OpenRouter forwards to Anthropic.

    “Hit rate ~1% today (ref #352).”

Choosing between OpenRouter and Portkey

Choose OpenRouter if

  • You want 500+ models from 80+ hosts on one balance without an account at each model maker.
  • Nobody should run a gateway, and a fee of 5.5% or 8% on credit purchases costs less than that work.
  • You need Zero Data Retention or EU and US in-region routing without negotiating each host's terms.
  • You will watch latency and errors per host from your own logs, since SRVpress left OpenRouter over both in October 2026.

Choose Portkey if

  • Traffic must reach the model makers on your own keys and contracts, through one governed gateway.
  • Security asks for recorded request logs, audit logs of admin actions, and guardrails tied to Prisma AIRS.
  • The data plane must run in your VPC while a vendor runs the control plane.
  • You can pay for Enterprise if you need SSO and organization management, which a TU Vienna team found locked behind it, or self-host the open-source gateway, which Glama now maintains as a fork.

What practitioners report, side by side

  • Portkey

Overall signal

All practitioners rate OpenRouter +10, 10 points above Portkey at 0. Most of the gap is in complaints, with 19 of Portkey's 50 sources negative against 30 of OpenRouter's 101.

The score counts the authors from all practitioners that take a side, one vote each with their latest view, and is how far positive votes lead negative ones, per 100 votes, so OpenRouter's +10 rests on votes split 40 positive, 30 mixed and 30 negative and Portkey's 0 on 18, 11 and 18.

A lead of a fifth of the votes reads positive and a lead of half strong positive, with the same lines below zero. The dots show each source, positive, mixed, negative. Run a pilot on one service's model traffic to measure added latency, failed fallbacks and how closely its spend records match each provider's bill.

Footprint on the AI Application Platform stack

They differ on one of 9 layers. On Model APIs, OpenRouter supports it and Portkey touches it. Coverage is each product's placement on this stack, as its product page shows it. Core is a job the product owns; Supports and Touches are jobs it helps with. Coverage says nothing about how well a product does them.

What practitioners praise

Among all practitioners, OpenRouter alone has three praise themes that reach 5 sources from 3 authors. One API and One Balance and Fast Access to New and Open Models lead, at 25 of 25 each. One API with Fallbacks and Request Logs & Cost Data reach 5 sources from 3 authors only for Portkey, at 16 of 17 and 8 of 8. OpenRouter needs a pilot on the same provider traffic before you choose on either.

Each count is the sources that praise a theme, or raise it as a concern, out of those that discuss it. A row pairs the two products when both carry a theme under the same or an equivalent name.

A count ending in "so far" has under 5 sources from 3 authors among all practitioners. "Not a theme in its sources" means GILD found no theme of that name in that product's sources.

What practitioners raise as concerns

Among all practitioners, OpenRouter alone has four concern themes that reach 5 sources from 3 authors. Fees & Billing Surprises and Provider Quality Variance lead, at 20 of 25 and 16 of 18. Portkey alone has three concern themes that reach 5 sources from 3 authors. Provider Translation Bugs and Reliability & Streaming Bugs lead, at 14 of 15 and 8 of 9.
