An agentic editor built around Cascade — a flow that keeps working across files without being re-prompted each step.
Windsurf is an AI-native editor whose central feature, Cascade, maintains state across a multi-step task: it tracks what it changed, runs commands, and keeps going. It also ships inline completion and rules files, and offers a self-hosted deployment for organisations with source-code constraints.
Multiple providers plus in-house models
Teams that want an agentic editor and need a self-hosting story.
