🏆 Which to Pick?
It's close — Windsurf scores 84/100 and Koidex scores 80/100. Pick based on your use case.
Windsurf
Windsurf is a strong alternative to Cursor, with an agent (Cascade) that plans and carries out multi-step changes. It is now owned by Cognition, the company behind Devin, and its pricing page redirects to Devin's plans, so expect the product and branding to keep converging.
Koidex
As AI coding tools install packages at machine speed, supply chain security becomes critical. Koidex is a no-brainer free layer of protection for any serious vibe coder.
