LoopBudget
About LoopBudget
LoopBudget provides a lightweight guardrail layer between developers and AI coding tools such as Cursor and Claude Code. It enforces soft and hard dollar caps on AI coding sessions, issuing a finance-readable receipt for each session that includes token usage, costs, and enforcement events. The tool is designed to shift spend control from a monthly forensic exercise to an immediate policy that runs with every session, preventing budget overruns before they happen. LoopBudget connects to AI tools via a single org API key, allowing teams to set spending limits without adding another dashboard to their workflow. Engineering teams retain visibility into real-time usage while finance receives clear, itemized records for auditing or chargeback purposes. The solution targets teams rolling out AI coding tools across multiple developers, offering a shared policy layer that complements single-vendor controls.

Frequently asked questions about LoopBudget
How is LoopBudget different from Cursor or Claude Code billing controls?
Cursor and Claude Code billing controls only govern their own tool, whereas LoopBudget acts as a shared policy layer that applies soft and hard spend caps across sessions, records enforcement events on a finance-readable receipt, and maintains a single ledger for both tools.
Isn't this the same as a cloud FinOps tool?
Cloud FinOps tools are not built for AI coding-agent sessions, which involve per-session billing and granular token-level usage. LoopBudget is designed specifically for Cursor and Claude Code sessions, offering per-session soft warnings, hard stops, and itemized receipts.
Does LoopBudget support Cursor and Claude Code today?
Yes, LoopBudget currently supports Cursor and Claude Code, providing guardrails and session receipts for both tools through a single integration.
Will spending caps get in developers' way?
LoopBudget is designed to allow teams to move quickly while preventing budget overruns. Soft warnings and hard stops are enforced only when limits are reached, minimizing disruption to workflows.
What does a session receipt include?
A session receipt includes token usage, dollar cost, soft-limit warnings, hard-stop events, and enforcement records, providing a clear, itemized record for both engineering and finance teams.
Do you see our code or prompts?
No, LoopBudget does not access or store code or prompts. It only tracks token usage, session costs, and enforcement events for budget control purposes.
