Show HN: Frugal Tokens – explore costs and usage across coding agents

The report

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.

The significance

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.

The context

It shows overall usage, estimated working time and overlapping sessions, and where your spend is coming from across models and cache misses

The read

It shows overall usage, estimated working time and overlapping sessions, and where your spend is coming from across models and cache misses. You can also jump directly to where a cache miss happened.
