Show HN: Frugal Tokens – explore costs and usage across coding agents
A developer has released 'Frugal Tokens,' a tool designed to help users track and optimize the costs of using AI coding agents. The project provides insights into cache usage, model pricing, and session-level spending patterns.
Why it matters
As AI-assisted coding becomes standard, managing the high costs of API tokens and cache efficiency is becoming a significant operational concern for developers and startups.
I wanted to share a project I’ve been working on called Frugal Tokens. I originally built it because I was curious to see how much all of my sessions cost and how much cache misses affected that spend. I’d noticed people had widely different spend profiles and wanted to better understand what might contribute to that. As I’ve worked on this, the tool has grown to show more usage patterns across all of your sessions. It shows overall usage, estimated working time and overlapping sessions, and where your spend is coming from across models and cache misses. I also have a few session level metrics with percentile breakdowns, along with a list of your sessions and high level info.
