LiteLLM vs YoloRouter

LiteLLM is an open-source AI gateway and LLM proxy for platform teams. It provides one OpenAI-compatible API to 140+ providers and 1,800+ models, with load balancing, lowest-cost routing and automatic selection of cheaper models for simple prompts. Teams can track usage and spend across keys, users, teams, organizations, tools, agents and MCP, then apply hard budgets and rate limits. Response and semantic caching can use Redis, S3 or GCS. LiteLLM can be self-hosted, including in air-gapped environments, and offers deployment through an official Helm chart or Terraform module. The maker says self-hosting has no telemetry and keeps data within the user's infrastructure. Listed security features include hardened non-root images, vulnerability scanning, SSO/JWT/RBAC controls and secrets-manager integrations. The free Open Source plan is self-hosted and includes 100+ providers, virtual keys, budgets, rate limits, fallbacks, logging and Prometheus metrics. A 30-day Enterprise trial key is available without a credit card.

YoloRouter is a gateway that sends AI model requests to multiple providers through a compatible API. It accepts OpenAI Chat Completions and Responses, Anthropic Messages, and Gemini generateContent protocols, and translates between supported formats when the client and provider use different ones. Routing includes ordered provider candidates, failover, and pooling of upstream keys; the documentation lists access to providers including OpenAI and Anthropic through one endpoint. Streaming uses Server-Sent Events with usage tracking. Alongside chat, the gateway exposes OpenAI Images and Videos APIs, with billing based on delivered images or video seconds. It can compress bulky tool output before forwarding it upstream and report measured savings. API keys can have model allowlists, rate and concurrency limits, budget caps, expiry, and revocation. The admin console supports multiple users, single sign-on, usage visibility, and account controls. Self-hosted deployment is a single binary with an embedded console, SQLite by default, or optional PostgreSQL. The self-hosted plan is free. Cloud billing uses top-up credits, with no subscription or minimum spend.
