A managed alternative to a self-hosted LiteLLM proxy
LiteLLM is a popular open-source proxy you deploy and operate yourself. Router One is a fully managed, OpenAI-compatible LLM API gateway that covers the same routing and fallback needs — plus built-in billing, observability, and worldwide reachability including Mainland China — with no infrastructure to run. Use it when you want one endpoint for 40+ supported models such as GPT, Claude, Gemini, and DeepSeek, plus Claude Code and Codex CLI workflows.
Managed gateway vs self-hosted proxy
| Feature | Router One | LiteLLM (self-hosted) |
|---|---|---|
| Hosting model | Fully managed — nothing to deploy or operate | Open-source proxy you self-host (managed tier also available) |
| Smart routing & fallback | EWMA latency + posted cost + 5xx rate, managed | Configurable routing and fallback you maintain |
| Observability | Per-request traces, tokens, and cost out of the box | Logging/observability you wire up (e.g. Langfuse) |
| OpenAI-compatible API | Yes — Chat Completions, drop-in base URL | Yes — OpenAI-compatible proxy |
| Provider access | Upstream access included through one Router One key | You supply and manage each provider API key |
| Accessible from Mainland China | China-reachable endpoint with published latency benchmark | Depends on where you host the proxy |
| Billing & payment | Built-in wallet: Stripe, USDT/USDC, WeChat Pay, Alipay | Bring your own provider keys and billing |
Where a managed gateway helps
No proxy to run
Self-hosting LiteLLM means provisioning, scaling, patching, and monitoring a proxy. Router One is managed, so you skip the ops and start with an API key.
Billing built in
Top up by card through Stripe, with USDT and USDC on six chains, or in RMB with WeChat Pay and Alipay — one wallet, no separate provider invoices to reconcile.
Reachable worldwide, including Mainland China
Hosting an open-source proxy does not solve reachability for a distributed team on its own. Router One's managed endpoint serves members everywhere, including Mainland China. Based on the China latency benchmark last updated 2026-05-15, Router One measured 110-130ms p50 across Beijing, Shanghai, and Shenzhen; individual networks may vary.
Switch with one base URL change
Both Router One and a LiteLLM proxy speak the OpenAI Chat Completions API, so moving over is usually a base URL and key change. Point your client at Router One and drop the keys you no longer need to manage.

FAQ
Is LiteLLM open source?
Yes. LiteLLM is an open-source, self-hostable proxy, and it also offers a managed tier. Router One is a managed gateway — the trade-off is run-it-yourself flexibility versus zero-ops managed access with billing and observability built in.
Can I migrate from a LiteLLM proxy?
Yes. Both are OpenAI-compatible, so most integrations move with a base URL and API key change. Tools and SDKs that work against a LiteLLM proxy work against Router One.
Do I still bring my own provider keys?
No. Router One includes upstream access and billing through a single key and wallet, so you do not manage a separate key per provider. One endpoint reaches 40+ supported models — browse them at /models.
Which should I choose?
If you want full control and are happy to self-host, LiteLLM is a strong open-source option. If you want a zero-ops gateway with upstream access, billing, and observability built in — reachable worldwide, including Mainland China — Router One removes the infrastructure work.
