Windsurf
by Cognition AI
Agentic AI IDE whose Cascade agent edits across your codebase
Last reviewed 2026-06-18
Windsurf is an AI-native code editor (a fork of VS Code) built around Cascade, an agentic coding engine that performs multi-step work across a codebase: reading context, editing multiple files, running checks, and iterating until a task is done. It also offers inline autocomplete and a Supercomplete suggestion feature for the line-by-line copilot loop. Windsurf was acquired by Cognition AI (makers of Devin) in 2025, and its 2.0 release integrates Devin as a cloud agent alongside local Cascade agents. Cascade can run multi-step edits with limited per-step confirmation, but a human still reviews and accepts the resulting changes, so in practice it operates as a supervised agent. Windsurf ships its own fast coding model (SWE-1.5) and also runs frontier models such as Claude.
What it can do
Make multi-step edits across the codebase (Cascade)
SupervisedCascade decomposes a natural-language request into a sequence of operations, reads context, edits multiple files, and runs checks, iterating until the task is complete; a human reviews and accepts the changes.
sourceSuggest code inline (autocomplete and Supercomplete)
CopilotProvides line-by-line autocomplete and intent-aware Supercomplete suggestions that the developer accepts as they type.
sourceDelegate tasks to a cloud agent (Devin integration)
SupervisedWindsurf 2.0 integrates Devin as a cloud agent running on its own VM, surfaced through an Agent Command Center that tracks local and cloud agents; delegated work still returns for human review.

Strengths
- +Cascade does genuine multi-step, multi-file agentic work inside a familiar VS Code-style editor
- +Ships a fast in-house coding model (SWE-1.5) and can also run frontier models like Claude
- +After the Cognition acquisition, integrates Devin as a cloud agent for delegated tasks
Limitations
- −Quota and credit changes after the acquisition have shifted what each tier includes
- −Multi-step agent runs still need human review; not a hands-off autonomous engineer
- −Now owned by Cognition, which also sells Devin, raising product-direction questions for some buyers
Overview
Windsurf is an AI-native IDE (a VS Code fork) built around Cascade, an agentic coding engine. Unlike a pure autocomplete tool, Cascade performs multi-step work across a codebase: reading context, editing multiple files, running checks, and iterating. Windsurf was acquired by Cognition AI, the maker of Devin, in 2025.
What it does
Cascade decomposes a natural-language request into a sequence of operations and executes them across the project, returning changes for the developer to review and accept, which makes it a supervised agent in practice. Windsurf also offers traditional inline autocomplete and an intent-aware Supercomplete suggestion feature for the line-by-line copilot loop. After the Cognition acquisition, Windsurf 2.0 added an Agent Command Center that tracks local and cloud agents and integrates Devin as a cloud agent running on its own VM.
Integrations & setup
Installs as a desktop editor, supports the VS Code extension ecosystem, consumes MCP servers, and connects to GitHub. It ships its own fast coding model (SWE-1.5) and can also run frontier models such as Claude.
Pricing
Freemium: a free tier plus a Pro plan around $20/mo, with higher Teams and Enterprise tiers. Plans use daily and weekly quotas; the specifics changed after the Cognition acquisition, so buyers should check current limits.
Best for / not for
Best for developers who want an agentic editor that can do multi-file work in a familiar VS Code-style interface. Less ideal for teams that want a fully hands-off autonomous engineer (that is closer to Devin's async model) or a vendor with no overlapping product.
Alternatives
Cursor is the closest agentic-IDE competitor; GitHub Copilot and Claude Code target the same coding workflows; Cognition's Devin (now the parent company) targets async delegated tickets.

FAQ
Is Windsurf's Cascade agent autonomous?+
Cascade runs multi-step edits across a codebase with limited per-step confirmation, but a human reviews and accepts the changes, so in practice it is a supervised agent. The plain autocomplete and Supercomplete features are a copilot loop.
Who owns Windsurf?+
Cognition AI, the maker of Devin, acquired Windsurf in 2025. Windsurf 2.0 integrates Devin as a cloud agent alongside local Cascade agents.
