Top 5 Portkey Alternatives in 2026

1. 01

   Wide product surface — easy to over-buy

   The Production tier ($49/month) and Enterprise pricing assume you want guardrails, governance, prompt management, and observability bundled together. Teams that only need a clean inference gateway pay for surface they will never exercise — and that surface still demands time to evaluate during procurement, even if it never gets switched on.

2. 02

   Virtual-key indirection in the route

   Portkey's virtual-key plus config pattern adds an abstraction layer between your application code and the upstream provider. It is powerful for governance and budget allocation, but when a route misbehaves there is one more place to inspect — and one more place to misconfigure. New engineers onboarding to the codebase have to learn the virtual-key concept before they can reason about why a request went to one model and not another.

3. 03

   Per-month + per-100K-logs overage model

   Production overage is $9 per additional 100K requests up to 3M. The model is predictable, but it adds a separate line to budget that is independent of actual inference spend. Finance teams have to track two cost surfaces (Portkey logs + upstream inference) instead of one, which is small in absolute dollars but adds friction in monthly reviews.

   Acquisition by Palo Alto Networks signals enterprise tilt

   Palo Alto Networks is an enterprise security buyer with a 40K+ employee install base. The acquisition is a positive signal for enterprise customers — and a directional signal to indie teams and startup engineering teams that future product roadmap will lean further toward enterprise gating: SAML SSO, Okta integration, custom MSA. The indie path is unlikely to be cut, but it is unlikely to be invested in either.

1. #1

   ElliotGate

   Editor's pick

   Visit site

   Calling-first gateway with OpenAI + Anthropic native protocols — pay only for tokens, no monthly minimum, no virtual-key indirection.

   Strengths

   • No subscription floor — pay only for actual usage.
   • Direct base URL swap, no virtual-key config layer to debug.
   • Multimodal in one balance — text, image, video, audio.
   • Per-token rate matches upstream provider exactly.

   Trade-offs

   • Guardrails, RBAC, and governance are not yet first-class.
   • Managed only — no self-host today.
   • Newer product than Portkey — smaller enterprise customer base.
   Pricing

   Pay-per-use across modalities; per-token text, per-call image, per-second video.

   Best for

   Indie teams and startup eng teams who want inference without enterprise overhead.
2. #2

   LiteLLM

   Open-source proxy unifying 100+ LLMs under OpenAI shape, with 240M+ Docker pulls and a Y Combinator backing.

   Strengths

   • OSS forever-free for self-host.
   • 40K GitHub stars, 1,005+ contributors — depth of community contribution.
   • Production-grade adopters (Netflix, Lemonade) cited publicly.

   Trade-offs

   • You operate the proxy and the database.
   • Enterprise pricing is contact-sales.
   Pricing

   OSS Free; Enterprise contact sales (30d trial).

   Best for

   Platform teams who want a proxy they fully operate and a wide LLM catalog.
3. #3

   Helicone

   Visit site

   AI gateway + LLM observability with 5.2K GitHub stars, recently joined Mintlify.

   Strengths

   • Strong tracing, sessions, HQL query language.
   • Hobby Free is a real free tier (10K req/mo).

   Trade-offs

   • Pro $79/month is a subscription floor.
   • Observability is the wedge — gateway is secondary.
   Pricing

   Hobby Free, Pro $79/mo, Team $799/mo, Enterprise contact.

   Best for

   Teams who want observability + gateway in one product and accept the subscription floor.
4. #4

   Langfuse

   Visit site

   Focused open-source LLM observability — traces, prompts, evals, datasets without gateway scope.

   Strengths

   • MIT-style open source with cloud + self-host options.
   • Clean separation from gateway — pair with anything.

   Trade-offs

   • Not a gateway — you still need calling layer.
   • Self-host requires Postgres + ClickHouse.
   Pricing

   Self-host free; Cloud Hobby/Core/Pro/Enterprise tiers.

   Best for

   Teams that separate observability from gateway and care about open-source ownership.
5. #5

   Strengths

   • Broadest LLM catalog of any gateway today.
   • BYOK with 1M free requests per month is strong for enterprises with provider contracts.

   Trade-offs

   • 5.5% platform fee compounds at scale.
   • Multimodal coverage thinner than text/embedding.
   Pricing

   Free 50 req/day, Pay-as-you-go +5.5%, Enterprise custom.

   Best for

   Teams who want the widest LLM catalog and already plan BYOK.

# No virtual-key abstraction. The model slug is the upstream slug.

Portkey's virtual-key + config indirection collapses to a single ElliotGate API key + an upstream model slug.
