BurnCap
AI cost control for small teams

Know which AI feature is burning money.

BurnCap ingests your LLM usage — an OpenAI import, a CSV, or a five-minute SDK — and shows cost per feature, customer and model. It forecasts month-end spend, alerts on runaway agents, and caps budgets before they destroy your margin.

How it works

From raw usage to a verdict, in minutes.

01

Send usage

Pull daily usage from the OpenAI or Anthropic admin APIs, upload a CSV, or track per-request with the TypeScript SDK. Idempotent by request id — retries never double-count.

02

See the burn

Spend by day, model, feature, customer and environment. Forecasted month-end. Estimated vs provider-billed, always labeled — no fake precision.

03

Cap it

Budgets per workspace, feature, customer or environment with 50/80/100% alerts. Hard caps return budget_exceeded through the SDK — your app stays in control.

Guardrails, not surprises

One check before the expensive call.

What you get

Everything the invoice hides.

01

Feature & customer breakdowns

Tag events with feature and customer_id; see exactly who and what burns money.

02

Forecast & spike alerts

Month-end forecast from your trailing average. Spike, runaway-loop, expensive-model and dev-spend detectors.

03

Budgets with real teeth

Alert-only by default. Soft and hard caps exposed to your app through one endpoint.

04

Unit economics

Cost per request, per active user, per paying customer — with margin % against the revenue you set.

05

Honest numbers

Every figure is labeled estimated, provider-billed or forecasted. Pricing overrides for negotiated rates.

06

Private by default

Token counts and identifiers only. No prompts, no completions, ever. Delete all usage data anytime.

Pricing

Cheaper than one surprise bill.
