LoopBudget

LoopBudget is an AI coding cost-control tool that puts hard and soft dollar caps on AI coding sessions in tools like Cursor and Claude Code, giving finance a receipt that shows where the money went. It sits as a lightweight guardrail layer between developers and their AI coding tools, with three behaviors: a soft warn when a session crosses a set threshold, a hard stop when it hits the cap, and a live session trail that records spend as it happens. Setup is minimal: you connect Cursor or Claude Code with one org API key, set soft and hard spend caps in dollars, then let LoopBudget enforce the policy and explain the spend on every session. The point is to move cost control from a monthly forensic exercise — where vendor dashboards and end-of-month invoices only tell you what happened after the money is gone — to a policy that runs with every session before overspend occurs. Each session produces a receipt that finance can read, tied to a session identifier and showing the soft and hard caps alongside actual spend. It is best for engineering and FinOps teams that need to cap and audit AI coding spend across a team once tools like Cursor and Claude Code spread beyond one or two developers.
