AUCT.us is just a humble fork of Cursor. As you should guess, Cursor is not free, but if you are serious about code and AI, you are probably really going to want Cursor.
At AUCT.us, we are giant fans of AI-first thinking used by the Cursor founders and consider Cursor tab, Cursor chat, Cursor CMD K along with Cursor Context and Cursor Advanced features to give us an early indication why Cursor will be THE code editor built from the ground up for programming with AI. Creating new posts on the forum for bugs or feature requests is much appreciated by the Cursor team.
Head over to the Cursor website to download and try out the Cursor editor for a no-cost two-week trial which includes 2000 completions and 50 slow premium requests ... but you are probably really going to want Cursor.
