FAQ

How does CostFence track Claude Code usage?

CostFence uses Claude Code's official OpenTelemetry (OTEL) metrics exporter. There are no SDKs, wrappers, or code changes required — just enable the exporter and point it to CostFence.

Is this officially supported by Anthropic?

CostFence is not affiliated with Anthropic, but it relies on documented and supported Claude Code metrics. If Claude Code emits it, CostFence can alert on it.

How real-time are the alerts?

Alerts typically fire within seconds of a limit being crossed. This means you can stop a runaway session before it drains your budget.

Do you store my prompts or code?

No. CostFence never stores prompts, responses, or source code. We only ingest usage metadata (tokens, cost, session IDs, timestamps).

What happens if CostFence goes down?

Nothing breaks. Claude Code continues to run normally. You simply won't receive alerts during the outage. CostFence is out-of-band monitoring, not a dependency.

Can I set multiple alerts?

Yes — depending on your plan.

  • Free: 1 daily + 1 session alert
  • Pro: Multiple daily and session alerts
  • Team: Multiple daily, session, and monthly alerts

What alert channels do you support?

We focus on signal, not notification spam.

  • Email (all plans)
  • Slack and webhooks (Team plan)

Why don't you charge per token or usage?

Because alerts shouldn't get more expensive when things go wrong. CostFence pricing is based on predictable alert value, not usage volume.

How is this different from dashboards like Helicone or LangSmith?

Those tools are great for analysis after the fact. CostFence is built for interrupting problems while they're happening. If you want charts, use a dashboard. If you want to stop surprise bills, use CostFence.

Can I use this for teams?

Yes. The Team plan supports:

  • Shared budgets
  • Team-wide alerts
  • Slack notifications
  • Alert history

Does this work for other LLMs?

Today, CostFence is laser-focused on Claude Code.

That focus is what allows us to deliver faster setup, better alerts, and simpler pricing.

We may expand later — but not at the cost of simplicity.

Is there a free trial?

Yes — the Free plan is unlimited time, no credit card required. Upgrade only when you need more alerts or team features.

How long does setup take?

Most users are up and running in under 5 minutes. Enable OTEL → set your limits → wait for your first alert.

Who is CostFence not for?

If you want deep analytics, model comparisons, or long-term reporting — CostFence may not be the right tool. If you want instant visibility into Claude Code costs, it is.
