Just want to add, I followed pretty much the same path with Windmill [1], which is also in the developer tool space, and also open-source. Built everything solo for 5 months. I thought it would be impossible to get into YC, it is not and I was fortunate enough to join YC on the latest batch, on my first try [2].
Getting into YC changed the course of the company, increased many orders of magnitude my ambition and made fundraising much easier. Most importantly, even though I worked in tech in the bay many moons ago, at the time I was very isolated in Paris and thought I understood the startup game but I did not really. Being part of a cohort like YC with like-minded amazing peers, truly felt like I was able to go up to speed on many subjects that would have been out of reach for a solo founder.
If you are a solo technical founder and considering applying to YC, reach out to me, I am more than happy to help.
