Do You Know Where Your LLM Budget is Actually Going?

Most teams pay their OpenAI or Anthropic bill every month without knowing which feature, user, or agent loop is burning the most tokens. TokenCurb is an LLM cost monitoring tool designed to show you exactly where your money goes and how to spend less.

Benefits

TokenCurb provides deep visibility into LLM spending, moving beyond simple monthly totals to offer granular insights. It is specifically built for teams using OpenAI, Anthropic, Google Gemini, and Mistral models. Unlike other tools that focus on debugging or general observability, TokenCurb specializes in cost visibility. Its key advantages include:

• Per-Feature Cost Breakdown:See exactly which part of your product costs the most to run, rather than just viewing a monthly total. This allows teams to identify high-cost areas immediately.
• Spike Alerts:Receive notifications before the damage shows up on your invoice, allowing for proactive cost management.
• Agent Loop Detection:Automatically flag agent calls that consume 10x more tokens than expected, helping to identify and fix inefficient loops.
• Model Routing Suggestions:Gain insights into which calls could run on a cheaper model without negatively impacting quality.

Teams with per-feature visibility typically cut LLM spend by approximately 35% through strategic routing, loop fixes, and spike detection.

Use Cases

TokenCurb is ideal for development teams and product managers who want to control their AI expenses. It helps users understand the financial impact of different parts of their application. For example, a team might discover that their chat feature costs significantly more than their embedding feature. Without this level of detail, it is difficult to determine which specific area requires optimization. The tool highlights critical insights, such as a specific agent loop consuming 12 times the average tokens, which is essential for cost reduction.

Pricing

TokenCurb operates on a no spam, no credit card basis for early access. Users can sign up for the waitlist to gain access once it opens. Additionally, there is a free LLM Cost Calculator available to estimate monthly API spend before joining the waitlist.

Vibes

The tool addresses a growing pain point as LLM costs rise and many teams lack visibility into their spending. By providing per-feature breakdowns, alerting on spikes, and detecting inefficient agent loops, it empowers teams to reduce their LLM spend by an average of 35% while maintaining performance.

Additional Information

In 2025, LLM API spend is projected to reach $8.4 billion, yet approximately 50% of teams do not track their costs effectively. TokenCurb offers a targeted solution to this problem by helping teams monitor and optimize their usage across major models like OpenAI, Anthropic, Google Gemini, and Mistral.
