I'm on Claude Max, so it didn't cost me anything more than the subscription I already have. Had to use it for Something. As for time - for the full CHasm and Fe2O3 suite of sw, I started the work 2026-03-29 and have probably spent 60h or so of my time. But then again I have a very tailored CC setup that I have fine-tuned since last summer with more than 70 CC projects helping me get it the way I need it to be since then.

So, it's at most $400 in Claude expenses for a fully custom suite of software in 2 months. Even if your time is 300/h, it's less than $2k in your own time (which, I would expect, you enjoyed spending). That's insanely impressive.

I need Claude Max in any case for my work, so the cost is effectively null. And I do creative stuff in my spare time regardless, and I don't really think about my hourly rate when I play with my kids either ;)

> That's insanely impressive.

literally every app they need, except the browser, at least have 10 alternatives that are FOSS, much more mature, better structured and prone to be bug free... or do you really think the OP with months/years of use won't need some other feature and will re-invent the wheel on software that is around for more than a decade with hundreds of bug reports done (i3 wm was released in 2009)

Did you miss a factor of 10 in that time-cost calculation?

As a hobby, normal rates don’t apply, but just not to be misleading on the equivalent cost.

Indeed, I forgot it. Must be $10-20k worth of human engineering time.

Interested to hear about your CC setup if you'd like to share.

@geir_isene: This is insanely cool, thanks for writing about it.

Do you know how much it would have been at API prices?

Can't speak for their usage, but I calculated my token use with Copilot, my employer paid 22$ for >2000$ in tokens. Given estimates margins, Github is paying 98-99% of the costs for us. I imagine Claude max etc is similar. So it's not sustainable at all

No idea. Probably quite expensive. I usually run 4-5 concurrent CC sessions, so hard to pinpoint for just CHasm and Fe2O3
