Helicone alternatives — including when to just use Helicone
Last verified
First, the honest part: Helicone is good. One base-URL change gets you per-request cost and latency, plus caching, with a usable free tier. If that's what you need, use it — nothing below is an argument against it.
People look for an alternative for three specific reasons. Each has a different answer.
Reason 1 — "I can't put a proxy in my request path"
The most common and most legitimate reason.
A proxy is an availability dependency. If it's slow, your product is slow; if it's down, your product may be down. Some teams simply can't accept that on a critical path, and some compliance regimes can't accept a second processor seeing prompt content.
What to use instead: a billing-API reader. Provider dashboards are free and accurate. TKN does the same across four providers with thresholds and a kill switch. Nothing touches your traffic.
What you give up: per-request cost, per-customer attribution, and freshness — billing data is daily.
Also consider: self-hosted Langfuse. If the objection is specifically _data leaving your estate_ rather than _anything in the path_, running it yourself resolves it while keeping request-level detail.
Reason 2 — "It's getting expensive at our volume"
Usage-based pricing on request volume scales with success.
What to use instead:
- Langfuse self-hosted. Open source, free to run, you pay in operational effort. The standard answer for high volume.
- LiteLLM. Open-source gateway you host yourself; routing and cost tracking without the per-request bill.
- Billing APIs. If what you actually look at is the daily total, you may be paying for per-request granularity you never open.
Worth checking before you migrate: which Helicone features do you use in a given week? Teams frequently discover they're paying for tracing and using a spend number.
Reason 3 — "I want to know total spend, not request spend"
A quieter reason, and often the real one.
Helicone tells you what went through Helicone. It cannot see the prototype key from March, the notebook a teammate runs, or the cron job nobody remembers. When a bill surprises you, the cause is frequently in that blind spot — so the tool bought to prevent surprises structurally misses the most common cause.
What to use instead: a billing-API reader, which sees every dollar on the account regardless of how the request was made. That's the coverage difference, and it's the argument for running both rather than swapping one for the other.
The alternatives, briefly
| Tool | Architecture | Best for |
|---|---|---|
| Langfuse | SDK, self-hostable | Deep tracing, data residency, high volume |
| Portkey | Gateway | Multi-provider routing with fallbacks |
| LiteLLM | Self-hosted gateway | Volume without per-request pricing |
| Provider dashboards | Billing | A free, accurate, definitive answer |
| TKN | Billing API, on a phone | Combined spend across providers, alerts, revocation |
| ccusage | Local logs | Claude Code and Codex session costs |
When to stay with Helicone
Genuinely, stay if:
- You need per-request cost, and the proxy hop is acceptable
- You need per-customer attribution for usage-based billing
- You're using its caching to cut spend — that pays for itself
- Setup time matters more than architectural purity
Those are real requirements and billing-API tools cannot serve them. Swapping to one because a comparison page told you to would be a downgrade.
The setup most teams land on
Both, doing different jobs:
- Helicone on the production service you're optimising — per-request detail where you need it
- A billing-API view for the account total — catching the traffic the proxy never sees
- A hard spend limit at each provider as the backstop
They overlap much less than the category naming suggests.
