Windsurf / Devin DesktopWindsurf / Devin Desktop

模型与开放条件Model & openness

Pro 档明确列出供应商：OpenAI、Claude、Gemini、SpaceXAI 以及领先开源模型。

自有模型 SWE-2 官方标注「Free use of SWE-2」， 定价页顶部另标注「SWE-2, our latest model, is now available」。

Free 档标注「有限模型可用性」（Limited model availability）。

The Pro tier lists providers explicitly: OpenAI, Claude, Gemini, SpaceXAI and leading open-source models.

The in-house model SWE-2 is officially labeled "Free use of SWE-2", and the pricing page header additionally states "SWE-2, our latest model, is now available".

The Free tier is labeled "Limited model availability".

运行位置Where it runs

重要变更：Windsurf 已改称 Devin Desktop——

官方文档标题为「agent-native editor」的稳定版本发布说明， 下载页同时提供 macOS（Apple Silicon / Intel）、 Windows（arm64 / x64）与 Linux x64 for Debian。

支持 SSH 或 WSL 主机上的文件夹选择。

Important change: Windsurf has been renamed Devin Desktop —

the official docs title the stable-release notes "agent-native editor"; the download page offers macOS (Apple Silicon / Intel), Windows (arm64 / x64) and Linux x64 for Debian.

Folder selection on SSH or WSL hosts is supported.

本地文件Local files

本地编辑器，直接读写工作区。官方 context-awareness 页原文： "The entire local codebase is then indexed (including files that are not open)"——整个本地代码库会被 RAG 上下文引擎索引，检索时按需取片段。

Pro 档有更大索引上限与上下文长度；Teams / Enterprise 可索引远端仓库。

.gitignore 内文件默认不对 Cascade 开放（Cascade Gitignore Access 默认关闭）；.codeiumignore 可排除路径。

Fast Context 是专门检索子代理 （SWE-grep / SWE-grep-mini 模型，仅用 grep / read / glob， 最多 4 轮、每轮至多 8 个并行工具调用）。亦可拖文件到面板或把选区发到聊天。

A local editor that reads and writes the workspace directly. Official context-awareness page wording: "The entire local codebase is then indexed (including files that are not open)" — the whole local codebase is indexed by the RAG context engine, with snippets fetched on demand at retrieval time.

The Pro tier has larger index caps and context length; Teams / Enterprise can index remote repositories.

Files in .gitignore are not exposed to Cascade by default (Cascade Gitignore Access is off by default); .codeiumignore can exclude paths.

Fast Context is a dedicated retrieval subagent (SWE-grep / SWE-grep-mini models, using only grep / read / glob, up to 4 rounds, at most 8 parallel tool calls per round). You can also drag files into the panel or send a selection to chat.

关机后的任务Tasks after shutdown

真后台来自 Devin Cloud：官方 windsurf/devin 页原文 "Each Devin session runs on its own VM with a desktop, browser, and computer use, so it can keep working after you close your laptop"——

每个 Devin 会话跑在自己的云端 VM，关掉笔记本仍继续。 可在本地用 Cascade 制定计划后一键交给 Devin 云端实现， 会话出现在 Agent Command Center。

本地 Cascade 与 Devin Local 则在你机器上运行（Devin Local "operates on your machine"），需客户端常驻。

注意 Devin Cloud 访问在逐步放开（rolling out），Enterprise 需管理员开启。

True background comes from Devin Cloud: official windsurf/devin page wording "Each Devin session runs on its own VM with a desktop, browser, and computer use, so it can keep working after you close your laptop" —

each Devin session runs on its own cloud VM, keeping working after you close the laptop. You can plan locally with Cascade and hand it to Devin cloud for implementation in one click, with sessions appearing in the Agent Command Center.

Local Cascade and Devin Local run on your machine (Devin Local "operates on your machine") and need the client resident.

Note Devin Cloud access is rolling out, and Enterprise requires an admin to enable it.

工具与扩展Tools & extensions

支持 Agent Client Protocol（ACP）—— 文档站有「Agent Client Protocol (preview)」与 「Building a custom ACP agent」两个专页，说明 ACP 处于 preview 阶段。

MCP 支持有一个重要细节：

changelog 记录 ACP 客户端传入的 MCP server 现在可被智能体使用并列出， 包括 HTTP 与 SSE 类型的 MCP server。

Supports the Agent Client Protocol (ACP) — the docs site has "Agent Client Protocol (preview)" and "Building a custom ACP agent" as dedicated pages, indicating ACP is in preview.

MCP support has one important detail:

the changelog records that MCP servers passed in by ACP clients can now be used and listed by the agent, including HTTP and SSE type MCP servers.

上下文与记忆Context & memory

Memories 机制已核到（官方 cascade/memories 页）：Cascade 在对话中自动生成并存储 memory，也可让它「create a memory」；

memory 与工作区绑定、存本地 ~/.codeium/windsurf/memories/、 不提交仓库、不消耗 credits，Cascade 认为相关时自动检索。

跨会话持久化官方推荐用 Rules（global / workspace / system 三级， .windsurf/rules/*.md）或 AGENTS.md。另有会话历史：

changelog 记录切回最近查看过的 10 个会话之一时，会立即显示其 transcript。

底层上下文引擎为 RAG（官方 M-Query 检索）。

The Memories mechanism is verified (official cascade/memories page): Cascade automatically generates and stores memories during conversations, and you can ask it to "create a memory";

memories bind to the workspace, stored locally at ~/.codeium/windsurf/memories/, not committed to the repo, consuming no credits, auto-retrieved when Cascade deems them relevant.

For cross-session persistence the official recommendation is Rules (global / workspace / system three levels, .windsurf/rules/*.md) or AGENTS.md. There is also session history:

the changelog records that switching back to one of the 10 most recently viewed sessions shows its transcript immediately.

The underlying context engine is RAG (official M-Query retrieval).

权限与限制Permissions & limits

有明确的安全机制与 CVE 修复记录： changelog 记录修复了 Restricted Mode 的一个绕过 （CVE-2026-81376）—— 原本只检查点号形式的受限工作区设置， 现在也检查嵌套对象形式。

这条值得注意：受限模式曾可被嵌套对象绕过。

There are explicit security mechanisms and CVE fix records: the changelog records a fix for a Restricted Mode bypass (CVE-2026-81376) — previously only dotted-form restricted workspace settings were checked, now nested-object form is checked too.

This one is worth noting: Restricted Mode could once be bypassed via nested objects.

适合什么任务Best for

需要多模型供应商可选（不想被单一模型绑定）的人； 需要 ACP 以接入自定义 agent 的人（注意是 preview）； 需要远程主机（SSH / WSL）支持的人。 Free 档适合只需要无限 inline edits 与无限 Tab 补全的人。

People who need multiple model providers to choose from (not locked to a single model); people who need ACP to plug in custom agents (note it is preview); people who need remote-host (SSH / WSL) support. The Free tier fits people who only need unlimited inline edits and unlimited Tab completion.

MCP servers passed by an ACP client ... are now usable by the agent
and listed in ..., including for HTTP and SSE MCP servers

Restricted Mode blocks restricted workspace settings written in
nested object form, not just the dotted form (CVE-2026-81376).
