Ask HN: Is $300/HR too low these days for custom full stack?

Background. I'm a solo dev. I used to just bid contract jobs at around 25% less than where I used to work. So back in 2008 I would bid $75k to go solo on a job I knew my former employer would charge $100k for. I switched to an hourly rate around 2012 because I was tired of re-negotiating over every new feature (or what constituted a feature). At that point I just did an estimate, backwards from my job rate, and settled on $75/hr. Since then I've increased to $300/hr.

But even back then, in 2012, I knew freelance consultants who specialized in something like Salesforce setups, who would come into someone's office and charge $450/hr to be there.

Is $300/hr stupidly cheap now? I also know which code I could write with LLMs but I never check in LLM code. I could, but that would be cheating. I spend the hours writing code by hand.

I'd like to hear from anyone in a similar position.
