DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for LiteLLM, the case for OpenRouter, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick LiteLLM
95.6 / 100- 61.3k+ GitHub stars under MIT license with 0% fee markup on your AWS Bedrock, Vertex, or Anthropic keys
- Self-hosted proxy keeps prompts, PII, and Redis semantic caches 100% inside your VPC
- Enforces per-developer, per-project, and per-key spend caps with automatic model fallbacks
When to Pick OpenRouter
93.0 / 100- Zero Docker or Postgres infrastructure to host; start routing across 400+ models in 30 seconds
- Automatic provider failover across fireworks, together, deepinfra, and first-party endpoints
- Unified prepaid credit balance eliminates managing 12 separate vendor billing accounts
When to Self-Host in Docker / K8s
Docker / Helm HA- $0 SaaS Usage / Per-Node Tax: Run on $18-$45/mo cloud VMs or bare-metal Kubernetes nodes with flat, predictable monthly compute.
- 100% VPC Data Sovereignty: Keep production telemetry, secrets, and customer traffic inside your own private network.
- Production HA Spec Included: Deploy with pre-tuned
traefik-ingress.prod.yml+helm-values.prod.yamlhealthchecks and resource limits.
