Windsurf

Also known as: Windsurf Editor / Codeium Windsurf / ウィンドサーフ

Codeium's AI editor with a Flow agent that tracks developer actions and proactively suggests next steps for context-persistent coding.

Overview

Windsurf is a leading AI editor alongside Cursor, combining VS Code-compatible UI with a proprietary Flow agent. Its unified conversation and action history delivers persistent context that survives editor restarts.

Differences from Cursor

Where Cursor emphasises model-switching flexibility, Windsurf focuses on the unique UX of proactive Flow-agent suggestions. Its free tier also includes a capable Agent mode, which has broadened its adoption.

Cognition AI's FrontierCode Explained: The Next-Gen Coding AI Benchmark That Asks 'Is It Mergeable?'

On June 8, 2026, Cognition AI unveiled **FrontierCode** — not a product, but a coding AI evaluation benchmark. It measures not just 'does it pass tests' but 'would an OSS maintainer actually merge this?' across six axes. This article covers its differences from SWE-bench Verified, the three-tier dataset (Diamond/Main/Extended), official results with Claude Opus 4.8 leading at 13.4% on Diamond, and its relevance to Japan's rigorous code-review culture.

Windsurf × Devin (Cognition AI) Integration Deep Dive — The 72 Hours That Reshaped the AI IDE Market and the Windsurf 2.0 Vertical Stack (May 2026)

The Windsurf (Codeium-origin AI IDE) and Devin (Cognition AI's autonomous engineer) story — grounded in the official [docs.windsurf.com/windsurf/devin](https://docs.windsurf.com/windsurf/devin) page and Cognition's announcement. Covers the July 2025 **"72 hours"** that reshuffled the market (OpenAI's $3B deal lapsed → Google's $2.4B reverse-acquihire of the CEO, co-founder, and ~40 R&D staff → Cognition's acquisition of the remaining assets the next Monday), the April 15, 2026 release of **Windsurf 2.0** with native Devin integration, automatic inclusion across Pro / Max / Teams plans, the $50 GitHub-connection credit, the Agent Command Center bringing local Cascade and cloud Devin into a single Kanban view, head-to-head comparison with Cursor, Claude Code, Antigravity, and Codex Computer Use, and adoption guidance for Japanese enterprises.
