AnonRouter vsLiteLLM

LiteLLM is an MIT-licensed proxy you run yourself, so there is no middleman to trust. It also means you hold an account with every provider, and each of them still knows exactly who you are.

What’s the difference between and ?

Both are open source and both put one OpenAI-compatible API in front of many providers. The difference is what sits between you and the model, and who is left knowing your name. LiteLLM gives you a proxy and SDK you run inside your own infrastructure, with routing, fallbacks, spend tracking, and logging under your control. AnonRouter puts a strict content-retention boundary and privacy-aware routing layer between your application and 200+ models, with nothing for you to deploy.

  1. You + Ticket

    Anonymous

    encrypted
  2. Protected hardware

    Intel TDX enclave

    protected
  3. Your model

    Private

Protected hardware isolates prompt handling. The model and provider you choose determine the route’s privacy level.

At a glance

AnonRouter vs LiteLLM

Eight things a hosted privacy router does that a self-hosted proxy structurally cannot. LiteLLM is not weaker software; it is solving the other half of the problem.

Anonymity toward the provider

AnonRouter

Yes. Requests reach the provider on our credentials, not on an account in your name.

LiteLLM

No. Your own provider key identifies you on every request.

Provider accounts you must hold

AnonRouter

None. One prepaid balance covers every provider in the catalog.

LiteLLM

One per provider, each with its own billing relationship.

Infrastructure to run and secure

AnonRouter

None. It is an HTTP endpoint.

LiteLLM

A proxy, a database, and a secret store that you deploy, patch, and keep up.

Confidential compute

AnonRouter

Yes. Prompt handling runs inside an attested hardware enclave.

LiteLLM

No. The proxy runs wherever you deploy it, with no attestation to offer.

End-to-end encrypted routes

AnonRouter

Yes, wherever the provider runs an enclave. The router holds no key.

LiteLLM

No. Prompts leave your proxy in the clear for the provider.

Privacy floor on automatic routing

AnonRouter

Yes. /auto stays inside a privacy boundary and fails closed when nothing qualifies.

LiteLLM

No. Routing is by cost, latency, and your own rules.

Account without an email address

AnonRouter

Yes. Private accounts open with a recovery phrase instead of an inbox.

LiteLLM

No. Every upstream provider account needs its own identity and billing.

Time to first request

AnonRouter

One key and a top-up.

LiteLLM

Provider sign-ups, billing setup, and a deployment first.

Where the privacy boundary sits

Self-hosting hides you from the middle. It cannot hide you from the end.

LiteLLM and AnonRouter are both open source and both solve a real privacy problem. They solve different halves of it, and the half you need depends on who you are hiding from.

Who sees your prompt

AnonRouter

An attested enclave, and on E2EE routes nothing else, because the router holds no key.

LiteLLM

Your own infrastructure, then the provider. Nobody in between, because you run the proxy.

What the provider knows about you

AnonRouter

Nothing identifying. Requests arrive on AnonRouter's credentials, with your identity held separately.

LiteLLM

Everything on the account. Requests arrive on your own API key, billed to your own company.

What you have to operate

AnonRouter

Nothing. It is an HTTP endpoint with a prepaid balance.

LiteLLM

A proxy, its database, its secrets, its upgrades, and its uptime.

Confidential compute

AnonRouter

Enclave-backed routes with an attestation you can pull and check yourself.

LiteLLM

Not part of the project. Your proxy runs wherever you deploy it.

Getting started

AnonRouter

One key and a prepaid balance. A private account does not need an email address.

LiteLLM

Sign up with each provider, add billing, hold every key, then deploy.

Why AnonRouter

Privacy is part of the architecture

The value is not only access to models. It is what the router is structurally unable to retain.

Audit the router instead of trusting it

Every component that can touch prompt plaintext is published under Apache 2.0, and the SDK checks the enclave's attestation against that build.

Remove prompt logging from the product

Prompts and responses are never written to disk. There is no router-side content logging switch to enable later.

Know what you pay

Model usage is billed at listed rates. Credit purchases include a separately disclosed platform fee, currently 5%.

Separate identity from request content

The private ticket flow splits the systems that know your account, handle plaintext, and hold provider credentials.

Route inside a privacy boundary

The /auto router filters to eligible privacy levels first, then selects for capability, quality, and cost.

See what every route guarantees

Anonymous, Private, TEE, and E2EE labels make the actual privacy boundary visible before a request is sent.

Upstream provider policy still matters either way. Neither a self-hosted proxy nor a no-log router can make every model provider private. Review the exact route label, and use an explicitly supported E2EE route when you need the strongest available boundary.

Which one is right for you?

Choose AnonRouter if…

  • The provider should not know who is asking
  • You would rather not run a proxy, a database, and a key store
  • Enclave-backed or end-to-end encrypted routes are a requirement
  • One prepaid balance beats an account with every provider
  • You want a private account without an email address

Choose LiteLLM if…

  • Prompts must never leave infrastructure you control
  • You need custom logging, spend tracking, or audit trails
  • A compliance regime requires a self-hosted data path
  • You already operate the infrastructure and want the control

Common questions

Against a middleman, yes: you run the proxy, so nobody between you and the provider sees anything. Against the provider, no. LiteLLM sends requests on your own API key, so every provider you use knows your company, your billing, and your traffic pattern. AnonRouter sends requests on its own credentials with your identity held separately, so the provider serves the request without learning who asked. Which one is more private depends entirely on who you are trying to hide from.
Yes. The core is MIT licensed, with an enterprise directory under a separate license. This is the rare comparison where the open-source argument is not a differentiator: AnonRouter's confidential content plane and verification SDK are Apache 2.0, and LiteLLM's core is MIT. The difference is that LiteLLM is code you deploy, while AnonRouter's published code is what runs inside an attested enclave on our side, which is why it ships with an attestation you can check.
Yes, and for some teams that is the best answer. Configure AnonRouter as an OpenAI-compatible provider inside LiteLLM. You keep local routing, your own logging, and full control of the deployment, and requests that leave your network reach model providers without your identity attached.
LiteLLM's software is free; you pay each provider directly, plus whatever the hosting, maintenance, and on-call time is worth. AnonRouter bills model usage at listed rates with a platform fee added when you buy credits, currently 5% during the launch promotion. Whether that is cheaper depends on how you value operating a proxy.
When prompts must stay inside infrastructure you control, when compliance requires a self-hosted data path, or when you need custom logging and audit trails that a non-retaining router cannot produce by design. Those are real requirements and AnonRouter does not meet them.
