Helicone vs LiteLLM (2026)
Both are open source and both sit in front of your model calls, with different centers of gravity.
LiteLLM is a routing layer first: one interface across a hundred plus providers with keys, budgets and failover, free to self host. Helicone is an observability layer first that happens to route, logging, caching and costing every request through one endpoint, free to ten thousand requests then 79 dollars a month. Teams often run LiteLLM for routing and something else for visibility, which is exactly the overlap worth checking before you buy both.
Choose Helicone if
- Logging, caching and cost attribution are the problem you are solving right now.
- You want a hosted option with a usable free tier rather than infrastructure to run.
- Per request visibility across teams and projects is what finance is asking you for.
Choose LiteLLM if
- Routing and failover across many providers is the requirement, and breadth is the metric.
- Budgets and virtual keys per team are how you want to control spend.
- Free self hosting with no request ceiling fits your volume better than a metered tier.
