Comparison
AgentCost vs Helicone
Helicone is an LLM observability and monitoring platform, offered as a hosted service with a free tier and paid plans.
Both AgentCost and Helicone answer the same underlying question: where is your LLM spend actually going? They differ mainly in how you integrate them and what you pay.
Helicone is a hosted product with a generous free tier and paid plans that scale with usage. AgentCost is MIT-licensed, free at every level, and designed to run on your own infrastructure — you install a Python SDK and host the backend yourself.

When to choose Helicone
- You want a managed service with no infrastructure to run, and someone to call when it breaks.
- You need SOC-2 or HIPAA compliance, which Helicone offers on its Team tier.
- Your team is happy routing traffic through a hosted gateway.
- You want a product with a longer track record than AgentCost currently has.
When to choose AgentCost
- You don't want request volume to determine your bill — AgentCost is free at any scale.
- Your data cannot leave your infrastructure. AgentCost self-hosts by default, with no telemetry.
- You'd rather not put a proxy in the path of every LLM call. AgentCost instruments the client libraries in-process instead.
- You want per-agent attribution in a multi-agent system as a first-class feature.
Frequently asked questions
Is AgentCost a drop-in replacement for Helicone?
Not exactly. Helicone commonly sits in the request path as a gateway, while AgentCost instruments the provider SDKs in-process. If you rely on gateway-level features such as caching or request routing, AgentCost does not replace those.
Is AgentCost really free, or is there a paid tier later?
It is MIT-licensed and free, with no tiers, seat limits, or paywalled features. You self-host it, so your only cost is the infrastructure you already run.
Can I run both?
Yes. They instrument at different layers, so running AgentCost alongside a gateway is possible, though you would be recording the same calls twice.
