Squiid vs Helicone
Helicone is observability for LLM calls: a proxy or async logger recording every request, response, latency and dollar. Squiid provisions and bills the whole stack. Complements, not rivals.
Short answer. If the question is what did my agent actually send and what did it cost, use Helicone. If the question is how many provider accounts, credentials and invoices this project carries, that is Squiid. Most teams serious about agents want both.
The one-line difference. Helicone tells you what happened to your model calls. Squiid holds the credentials and the balance for every service your app spends on.
Side by side
| Helicone | Squiid | |
|---|---|---|
| What it covers | LLM observability. A proxy or async logger recording requests, responses, latency, errors and cost, with caching and rate limiting. | The whole catalogue: databases, hosting, email, SMS, storage, auth and payments, models included. Model calls go to a named provider, not a router. |
| Non-AI services | No. It observes model traffic. Your database and email sender are elsewhere. | Yes. Postgres, object storage, email, phone numbers, error tracking. |
| Provisioning of accounts | No. You bring the accounts and keys; Helicone sits in the path or receives the logs. | Yes. Squiid opens the account and holds the credential. |
| Key custody and rotation | You hold every provider key. Proxied requests pass through a third party, which matters for sensitive prompts. | Squiid holds and rotates the provider keys. Your project carries one gateway key, worthless outside it. |
| Billing model | You pay providers for usage. Helicone charges for the observability product, as of their public docs. | Prepaid credits at par: $1 of credit is $1 at the provider. Subscriptions pass through at list price. |
| Fee | No markup on inference. | Free $0/mo + 15% at top-up. Solo $19.97/mo from 8%, falling to 3.5% with spend. Team from $29.97/seat, one point lower. Custom 3% or less. |
| One invoice PDF | A Helicone invoice plus one per model provider. | Yes. One monthly PDF: credits, plan, subscriptions. |
| Spend caps and pause-on-zero | Cost tracking, alerting and rate limits. It reports and throttles, but holds no balance to run out of. | Yes. Alerts at 75, 90 and 100%, capped auto top-up, pause at zero. |
| Works with coding agents | Yes. Usually a base URL plus a header. | Yes. One variable and one base URL convention for every service. |
| Self-host option | Yes. Open source and self-hostable, as of their public docs. | No. Hosted only. Leaving is a transfer where the provider supports one, a documented export otherwise. See handover. |
| Best for | Anyone who needs to see, debug and attribute what their agents sent. | Projects where the model bill is one line next to the database. |
When to pick Helicone instead
Pick Helicone when you are debugging behaviour rather than managing procurement. Nothing in Squiid shows you the prompt that produced a bad answer, the retry storm that tripled your bill, or which user accounted for a third of last week.
Pick it when cost attribution per user or per feature matters. Knowing the onboarding flow costs eleven cents per signup is a product decision, and it needs request-level data.
Pick it when caching repeated calls is worth money. Agent loops repeat themselves, and a cache in front of an expensive model pays for itself quickly.
Pick it if the observability stack has to stay inside your own perimeter. Self-hosting matters when prompts contain customer data.
When Squiid is the better fit
Squiid is the better fit when the problem is upstream of observability: the accounts are not open, keys are spreading through .env files, and invoices arrive from eight vendors. Observability makes a mess legible; Squiid reduces how much exists.
It is also the better fit for the non-model half of the bill. A request log says nothing about what Postgres, the phone number and the bucket cost this month. Those run on the same balance and invoice.
And it is the better fit for a hard stop. Alerting tells you spend is high; a balance that pauses at zero means it cannot keep going while you are asleep.
Use both
Close to ideal, because there is almost no overlap. Squiid is the account, the key and the balance; Helicone is the microscope. Squiid also carries Sentry, PostHog, Axiom and Better Stack, so the rest of your telemetry sits on the same invoice.
Questions people ask
Does Squiid replace Helicone?
No, and it should not be sold as if it does. Squiid reports what each service cost and which key called it, but stores no prompts, responses or request-level traces.
Can I run Helicone in front of Squiid?
For model calls, the shapes are compatible: both are a base URL and a header. Whether it is worth it depends on whether you want the prompt log, since Squiid already meters the spend.
Does routing prompts through a proxy raise privacy questions?
It should. Any proxy that logs requests sees whatever is in them, which is why self-hosting exists. Squiid meters calls at its gateway too; see the privacy policy and the DPA.
Which one stops an agent from overspending?
Helicone can rate limit and alert. Squiid holds the money: calls pause at zero across every service, not just models. Using both is not excessive.
Do I need either if I only make a few calls a day?
Probably not. At that scale a provider dashboard is enough. Both start earning their place when several agents, environments or people are involved.
Seeing the spend and
holding it are different jobs.
Squiid holds the credentials and the balance. Bring your own microscope.
