A production-grade alternative to LiteLLM
LiteLLM is a great place to start. Teams move to Routeplane when the edge becomes regulated and high-throughput.
LiteLLM’s Python proxy is a superb way to unify providers and prototype fast. The reasons teams look for an alternative are operational, and they cluster:
- Tail latency under load. A garbage-collected Python proxy has unpredictable pauses. Routeplane’s Rust data plane targets sub-5 ms added p99 with no GC tails.
- Governance you don’t have to assemble. Deterministic PII/secret redaction and prompt-injection detection are first-class request stages, not callbacks you wire up.
- Sovereignty as a built-in. Per-request classification of regulated data and region-locked routing across clouds.
Feature-by-feature
| Capability | routeplane | LiteLLM |
|---|---|---|
| No-GC Rust data plane | ✓ | ✗ Python (GC) |
| Per-request regulated-data classification | ✓ | ✗ |
| Region-locked routing per request | ✓ | ✗ |
| Deterministic guardrails on hot path | ✓ | ◐ callbacks |
| Multi-currency FinOps | ✓ | ✗ |
| Fully open source | ◐ self-host | ✓ |
Which should you choose?
Choose routeplane when
- Predictable p99 latency under production load matters.
- You need residency enforced per request and guardrails on the hot path.
- Finance needs currency-aware chargeback by team and project.
Choose LiteLLM when
- You want a fully open-source, forkable Python codebase today.
- Maximum model breadth out of the box is the priority.
Migrating to routeplane
If your apps already talk to a LiteLLM proxy over the OpenAI shape, switching is a base-URL change. Keep your SDKs; gain a no-GC data plane, inline guardrails, and sovereign routing.
Frequently asked questions
Is Routeplane a drop-in LiteLLM replacement?
For the OpenAI-compatible gateway surface, yes, adoption is a base-URL change. Routeplane is not a Python library you import; it’s a standalone Rust data plane you put in front of your apps.
When should I stay on LiteLLM?
If you want a fully open-source, Python-native, maximally hackable proxy and you don’t yet have residency or hot-path-latency requirements, LiteLLM is a great fit. Routeplane is for when those requirements arrive.
See the residency header come back true.
