Deep Dive: Switching from Windsurf to Kilo Code
Trade-offs, installation & data architecture
Why fork Kilo Code instead of vibe-coding a Windsurf clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Windsurf, build a VS Code extension that proposes and applies reviewed multi-file patches. The hard boundary is proprietary coding models, agent context, ide integration, and hosted inference, plus frontier models, context infrastructure, and execution safety.
