AnonRoutervs LiteLLM
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.
Running the proxy yourself removes the middleman. It does not remove your name from the request.
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.
Read the code that handles your prompt
A privacy claim about a closed service can only ever be a statement of intent. These two repositories are the reason ours is not.
Nothing to run
No proxy, database, or key store to operate
No provider account
The provider never learns who you are
Apache 2.0
The code that touches your prompt is public
The core difference
Built for different guarantees
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
Built to be self-hosted
LiteLLM gives you a proxy and SDK you run inside your own infrastructure, with routing, fallbacks, spend tracking, and logging under your control.
Best for:
- Full control of the deployment
- Data that must never leave your network
- Custom logging and spend tracking
- Teams happy to run infrastructure
AnonRouter
Built for private model access
AnonRouter puts a strict content-retention boundary and privacy-aware routing layer between your application and 200+ models, with nothing for you to deploy.
Best for:
- Provider-facing anonymity
- Enclave-backed and E2EE routes
- No infrastructure to run or secure
- One prepaid balance instead of many accounts
Feature comparison
What you get here and nowhere else
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.
Why AnonRouter
Why teams choose AnonRouter
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.
Pay a lower platform fee
Model usage bills at the displayed provider rate. The only charge is a platform fee on credit purchases, 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.
Choosing
When to choose which
This is the one comparison on the site where the honest answer is often the other product, and sometimes it is both: point LiteLLM at AnonRouter and you get local control with provider-facing anonymity behind it.
Choose LiteLLM when
- 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
Choose AnonRouter when
- 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
