TokenBudget: Cost Guard for Coding Agents

Set token budgets for AI coding agents and stop runaway bills

Problem

Developers using AI coding agents often see token costs explode because agents run full test suites or re-read files repeatedly. One user burned $1,200 in a single afternoon. Most only discover the spend when the bill arrives, with no real-time control during a task.

Solution

A local cost monitoring and interception tool: tracks token usage per request in real time, lets users set budgets per task, pauses the agent and alerts when overspending, and provides per-task/project cost reports to help optimize prompts and agent behavior.

Users

Indie developers and small teams who heavily use AI coding agents like Claude Code or Codex

MVP

Capture token usage via proxy gateway or log parsing; set daily and per-task budgets; trigger alerts and optional agent pause when budget exceeded; generate weekly cost reports per task

Revenue

Open-core with paid hosted/team edition (multi-user budget management, alert integrations), or subscription per monitored agent instance

Why now

AI coding agents are becoming mainstream and token costs are significant; demand for cost visibility and control is emerging with no mature lightweight tool yet
