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 China-reachable access, local payment, and built-in billing and observability — with no infrastructure to run. Use it when you want one endpoint for 25+ 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) |
| Accessible from Mainland China | China-reachable endpoint with published latency benchmark | Depends on where you host the proxy |
| Billing & payment | Built-in wallet: WeChat Pay, Alipay, Stripe, USDT/USDC | Bring your own provider keys and billing |
| Provider access | Upstream access included through one Router One key | You supply and manage each provider API key |
| Observability | Per-request traces, tokens, and cost out of the box | Logging/observability you wire up (e.g. Langfuse) |
| Smart routing & fallback | EWMA latency + posted cost + 5xx rate, managed | Configurable routing and fallback you maintain |
| OpenAI-compatible API | Yes — Chat Completions, drop-in base URL | Yes — OpenAI-compatible proxy |
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.
China access without VPN
Hosting an open-source proxy does not solve Mainland China reachability on its own. 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.
Local payment built in
Top up in RMB with WeChat Pay, Alipay, Stripe, plus USDT and USDC on six chains — no foreign credit card and no separate provider invoices to reconcile.
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.
# Replace your LiteLLM proxy base URL with Router One export OPENAI_BASE_URL=https://api.router.one/v1 export OPENAI_API_KEY=sk-your-router-one-key
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 China reachability and local payment 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 25+ 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 managed access from China with WeChat Pay/Alipay/stablecoin billing and built-in observability, Router One removes the infrastructure work.
