As a solo dev, I use $5 VPS on OVH or Hetzner for peace of mind. I remember trying out GCP for some simple html or django thing a decade ago and it cost me $30/mo or something and I said nah. I've also seen an ex-coworker rack up $50k with no recourse. I've already read enough horror stories like this.
