Cline 是什么？What Is Cline?
Cline（前身叫 Claude Dev，VS Code 扩展 ID 至今仍是 saoudrizwan.claude-dev）是跑在编辑器侧边栏里的自主编程智能体：读你的代码库、创建和编辑文件、执行终端命令，还能用 Puppeteer 驱动真实浏览器——每一步关键操作都要经过你的审批。它是开源 IDE agent 路线的幸存者：2026 年 Roo Code（它的 fork）已于 5 月 15 日关停、Continue 并入 Cursor 后转为只读、Kilo Code 被 Anaconda 收购，Cline 以约 7 万 star 成为这条路线的现存主线。Cline (formerly Claude Dev — the VS Code extension ID is still saoudrizwan.claude-dev) is an autonomous coding agent living in your editor's sidebar: it reads your codebase, creates and edits files, runs terminal commands, and even drives a real browser via Puppeteer — with your approval required at each consequential step. It is the survivor of the open-source IDE-agent lineage: in 2026 Roo Code (its fork) shut down on May 15, Continue went read-only after joining Cursor, and Kilo Code was acquired by Anaconda — Cline stands as the surviving mainline with ~70k stars.
2026 年它依然在高频更新：4 周 313 次提交、每周新增约 478 star（2026-10 核实）；VS Code Marketplace 安装量超 500 万（2026-09 约 529 万）。扩展版本 v4.0.10（2026-07），Cline 桌面应用与 CLI（npm i -g cline）并行迭代。背后是 Cline Bot Inc.，2025 年 7 月完成 $5M 种子轮 + $27M A 轮（估值约 $1.1 亿）。It is still shipping fast in 2026: 313 commits in four weeks and ~478 new stars per week (verified Oct 2026); over 5 million VS Code Marketplace installs (~5.29M in Sept 2026). Extension at v4.0.10 (July 2026), with the Cline desktop app and CLI (npm i -g cline) iterating in parallel. Behind it is Cline Bot Inc., which closed a $5M seed + $27M Series A in July 2025 (valued around $110M).
模型完全自由（BYOK）：30+ 提供商——Anthropic、OpenAI、Google、OpenRouter、AWS Bedrock、GCP Vertex、Groq、Cerebras、DeepSeek，以及本地 Ollama / LM Studio。扩展本身免费，成本就是模型 token；另有 ClinePass（$9.99/月，开源模型阵容）与 Cline Provider 按量付费，Teams $20/人/月（前 10 席免费）。价格以官网为准。Model choice is fully free (BYOK): 30+ providers — Anthropic, OpenAI, Google, OpenRouter, AWS Bedrock, GCP Vertex, Groq, Cerebras, DeepSeek — plus local Ollama / LM Studio. The extension is free; you pay only for model tokens. There is also ClinePass ($9.99/mo, open-weight model lineup) and pay-as-you-go via the Cline Provider; Teams is $20/user/mo (first 10 seats free). Confirm prices on the official site.
Cline 是开源 IDE agent 这波浪潮里最后的主线，而且是凭实力留下来的：约 7 万 star、4 周 313 次提交、背后有真正的公司。它的产品洞察是一个循环：Plan（只读出方案）→ 审批 → Act（执行）→ Checkpoints（回滚）。这种"人在回路"的纪律性，加上 BYOK 的模型自由，就是为什么已经买了多个模型订阅的开发者愿意只用它一个界面。诚实的一面：BYOK 意味着 token 账单自己扛——大仓库的全文件上下文烧得很快，重度用前沿模型一个月能烧掉数百美元（日常探索用本地/便宜模型是主流省钱姿势）；而 2026 年 2 月的供应链事件是永久提醒：把 agent 工具当特权软件对待，固定来源、保持更新。
Cline is the last mainline standing of the open-source IDE-agent wave — and it earned it: ~70k stars, 313 commits in four weeks, a real company behind it. The product insight is a loop: Plan (read-only proposal) → approve → Act (execute) → Checkpoints (roll back). That human-in-the-loop discipline plus BYOK model freedom is why developers who already pay for model subscriptions keep a single interface. The honest caveats: BYOK means you meter your own token bill — full-file context on big repos burns fast (heavy frontier-model sessions can run into the hundreds of dollars a month; local/cheap models for exploration is the standard saving move); and the February 2026 supply-chain incident is a permanent reminder to treat agent tooling as privileged software — pin your sources, keep it updated.
