Despite their impressive ARR, Cursor faces existential threat from not only BigLabs (Claude Code, Open AI Codex) but also BigTech (AWS Kiro, Google Antigravity, MS VSCode). I am sure the usual suspects would have lined up to purchase Cursor, and the deal from xAI was probably the best of the lot. Marks an end to a remarkable sprint for a 3yo company, and an admirable exit (considering the recent discombobulation of Windsurf's), just as investor money and/or hype is going belly up.
It has shown surprising stickiness. Occupying some middle ground between full adoption and still ~in the code.
I am starting to see some potential in moving back away from pure terminal, a mixed modality with AI. But it is not in the direction of IDE in any traditional sense.
Having tried most (all?) of the commercially available + open source options, and even tangential competitors like CC, Conductor, Antimetal, etc. I haven't found anything that's close to the experience of Cursor. The harness they've built is incredible.
I'd even go so far as to say that any competitors that are direct (windsurf, kiro, etc.) aren't even in the same universe. Cursor is just so much better, faster, has better features (plan and debug mode), and squeezes much better results/code out of the same models. They absolutely have some secrete sauce that the other options just don't have.
