Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. S-tier if you self-host. The reason open-source image gen matters.
