Direct alternatives to LiteLLM
If you came here from "litellm alternatives", you probably want what LiteLLM does: a self-hosted, OpenAI-compatible proxy (plus Python SDK) that gives one interface to 100+ LLM providers, with cost tracking, load balancing, and fallbacks. The closest direct replacements:
- Portkey: open-source AI gateway routing to 1,600+ LLMs across 200+ providers, with retries, fallbacks, and load balancing, plus observability, guardrails, and prompt management on top.
- OpenRouter: a hosted aggregator instead of a proxy you run. One API and one bill across providers, no infrastructure to operate, but your requests flow through a third party.
- Cloudflare AI Gateway: managed proxy at Cloudflare's edge with caching, rate limiting, retries, and cost analytics. No self-hosting, and pairs naturally with an existing Cloudflare stack.
- Vercel AI Gateway: routing layer for hundreds of models with built-in rate limiting and key management, tightly integrated with the Vercel AI SDK.
- TrueFoundry: enterprise-leaning gateway routing across 250+ LLMs with latency-based routing, guardrails, RBAC, and rate limiting.
- Helicone: proxy-style integration focused on observability: logging, caching, and rate limiting across providers. A common pick when monitoring is the main need alongside routing.
One distinction worth keeping in mind: LiteLLM is open source and runs in your own infrastructure. Portkey's gateway is also open source and self-hostable; OpenRouter, Vercel AI Gateway, and Cloudflare AI Gateway are managed services. If self-hosting is a hard requirement, that narrows the list quickly.
The full list below also includes orchestration frameworks and observability tools that share LiteLLM's categories but solve a different problem than provider routing.
