What is BudgetKit?

BudgetKit wraps your Anthropic/OpenAI/Gemini calls invisibly, tracks cost per user, enforces per-plan limits, and fires alerts before a single free user generates a $300 bill. One line change. Zero behavior change. Never wake up to a surprise AI invoice again.

// After — identical response, fully tracked:
const response = await budget.track(userId, () =>
  anthropic.messages.create({ model: 'claude-sonnet-4-6', max_tokens: 1024, messages })
)
