LiteLLM - Pros & Cons
Pros
- ✓Open-source edition has no license charge for production self-hosting
- ✓One interface reduces application coupling to individual providers
- ✓Centralizes model and MCP access, cost controls, and logs
- ✓Supports private and air-gapped deployments
Cons
- ✗The customer must operate a critical production gateway
- ✗Enterprise pricing is custom and requires an annual agreement

- ✗Provider-specific behavior can leak through the normalized API
Helicone - Pros & Cons
Pros
- ✓Truly one-line integration — fastest path to LLM logging in the market
- ✓Open source under Apache 2.0 with viable self-host story (not just open-core marketing)
- ✓Generous 10,000-request free tier covers most prototypes and small side projects
- ✓Gateway + observability in one tool reduces vendor count for small teams
- ✓Vault feature lets you put provider keys server-side without rewriting the client
Cons
- ✗Proxy adds 50–200ms latency in some regions versus calling the provider directly
- ✗Async/log-only mode exists but loses many gateway features (caching, fallback)
- ✗Trace/session UI is less polished than LangSmith for deeply nested agent runs
- ✗$79 → $799 jump from Pro to Team is steep if you only need SSO
- ✗Self-host docs assume Kubernetes/Postgres comfort; not push-button
