引言

2026 年，如果你想让终端里的 AI 帮你写代码、改 Bug、搭一个能直接部署的全栈应用，通常要付这笔账：Cursor 约 240 美元/年、Claude Code 约 1200 美元/年、Devin 则高达 2400 美元/年。而 freebuff.com 给出的答案是 0 美元、永久免费——一款由广告补贴、无需 API Key、无需信用卡的免费 AI 编程智能体，已吸引 30 余万开发者加入。

需要先说明一个事实：Freebuff 并不是传统意义上「提供 REST 接口」的 API 平台，而是一个免费的 AI 编码智能体（Coding Agent）。但它的价值恰恰在于——把那些原本需要付费 API 才能调用的前沿大模型（DeepSeek V4、MiniMax M3、GLM 5.2 等）免费开放给你使用。对开发者而言，效果等同于「免费拿到了多款顶级模型 API 的额度」。

免费能用到的模型矩阵

Freebuff 免费层内置了多款 2026 年主流前沿模型，并根据任务自动选择最合适的：

模型	定位	免费说明
DeepSeek V4	推理/智能最强	免费，含 V4 Flash / V4 Pro
MiniMax M3	速度最快	免费
GLM 5.2	编码精度高	免费
MiMo 2.5 Pro	均衡全能	免费
Gemini 3.1 Flash Lite	文件查找	免费（内置子代理用）
GPT-5.4 / GPT-5.6	深度思考	连接你自己的 ChatGPT 订阅（BYOK）
Claude Code	编码	支持 BYOK 接入

其中 DeepSeek V4 Flash 每天提供 6 小时免费额度，全球可用。这意味着你每天都能白嫖数小时的顶级模型算力。

五种产品形态

Freebuff 把同一套免费模型能力做到了五种形态，覆盖不同工作流：

产品	形态	对标付费工具	说明
Freebuff CLI	命令行	Claude Code、Codex CLI	终端里运行，`npm install -g freebuff`
Freebuff Desktop	桌面应用	Cursor	macOS/Windows/Linux，可并行跑多个 Agent
Freebuff Web	网页应用构建器	Lovable、Bolt、Replit	一句话生成全栈应用并部署
Freebuff Cloud	云端 IDE	Devin、Factory	沙箱内改任意 GitHub 仓库并预览
Freebuff Chat	免费 AI 对话	ChatGPT Plus、Perplexity	深度研究式问答

快速上手：从安装到生成 PR

1. 安装 CLI

npm install -g freebuff

2. 进入项目并启动

cd your-project
freebuff

首次运行会自动索引你的代码仓库，之后保持索引热更新。无需注册、无需 API Key、无需信用卡。

3. 用斜杠命令完整流程

Freebuff 内置了打磨过的斜杠命令，把一个模糊想法变成一份可合入的 PR：

/interview  →  澄清需求
/plan       →  制定实现计划
implement   →  自动编写代码
/review     →  代码审查

每次回答后，Freebuff 还会给出三个可点击的「下一步」建议，让对话不会陷入死胡同。

内置的 9 个专用子代理

Freebuff 开箱自带 9 个专用子代理，由主 Agent 自动编排调度：代码审查（code-reviewer）、浏览器自动化（browser-use）、文件查找（file-picker）、深度思考（thinker-with-files-gemini）等，覆盖编码、检索、审查等完整链路。

关于「永久免费」的商业逻辑

Freebuff 的免费并非临时促销，其成本由终端内的纯文本广告补贴——广告只出现在 Agent 动作之间，绝不出现在生成的代码里或变成弹窗。官方承诺：核心产品永不向你索要信用卡。如果你确实想去除广告，官方提供了付费升级路径（Codebuff Pro），但 95% 只是想「把代码 ship 出去」的开发者用免费版就足够了。

地区与限制模式（Limited Mode）

免费完整模式在 25+ 个国家/地区可用；在这些地区之外、或使用 VPN 时，Freebuff 会降级到「受限模式」：仅提供 DeepSeek V4 Flash，每天 6 个一小时的会话。依然是免费，官方也在每月扩大完整模式覆盖范围。

使用建议与注意事项

代码隐私：上传文件与其连接的仓库不会提供给广告供应商；但提示词和消息可能被分析以个性化广告。标注「May use data for AI training」的模型可能把输入用于训练。
敏感代码：涉及私有/敏感代码时，建议阅读官方隐私 FAQ 后再决定是否使用。
适合场景：快速原型、个人项目、学习练手、把现有仓库交给 Agent 做重构/加测试。
替代思路：Freebuff 本质上是用「免费 Agent」替代了「付费模型 API + 付费编码工具」的组合，是最直接的省钱方案之一。

小结

Freebuff 的出现，把「调用前沿大模型」这件事从按量付费的 API 账单，变成了广告补贴下的零成本体验。它不是 API 平台，却把 DeepSeek V4、MiniMax M3、GLM 5.2 这些顶级模型的「免费额度」直接放进了终端和浏览器。如果你正在寻找免费 AI 编码/模型资源，freebuff.com 值得第一时间体验。

Introduction

In 2026, if you want an AI in your terminal to write code, fix bugs, and scaffold a deployable full-stack app, you're usually looking at a bill: ~$240/yr for Cursor, ~$1,200/yr for Claude Code, and up to $2,400/yr for Devin. freebuff.com answers with $0, free forever — an ad-supported AI coding agent that needs no API key and no credit card, already joined by 300,000+ developers.

One clarification up front: Freebuff is not a traditional REST API platform — it's a free AI coding agent. But its value is exactly this: it gives you free access to frontier models (DeepSeek V4, MiniMax M3, GLM 5.2, etc.) that you'd otherwise have to pay to call via APIs. For developers, that's effectively the same as getting free quota across several top-tier model APIs.

The Free Model Lineup

Freebuff's free tier ships multiple leading 2026 models, automatically picking the best fit per task:

Model	Strength	Free Note
DeepSeek V4	Best reasoning/intelligence	Free, includes V4 Flash / V4 Pro
MiniMax M3	Fastest	Free
GLM 5.2	Coding precision	Free
MiMo 2.5 Pro	Balanced	Free
Gemini 3.1 Flash Lite	File finding	Free (built-in subagent)
GPT-5.4 / GPT-5.6	Deep thinking	BYOK via your own ChatGPT subscription
Claude Code	Coding	BYOK supported

DeepSeek V4 Flash offers 6 free hours per day, available globally — several hours of top-tier model compute each day, for free.

Five Product Forms

Freebuff delivers the same free model capability across five forms to fit different workflows:

Product	Form	Replaces	Notes
Freebuff CLI	Command line	Claude Code, Codex CLI	`npm install -g freebuff`
Freebuff Desktop	Desktop app	Cursor	macOS/Windows/Linux; run agents in parallel
Freebuff Web	Web app builder	Lovable, Bolt, Replit	One prompt → full-stack app → deploy
Freebuff Cloud	Cloud IDE	Devin, Factory	Edit any GitHub repo in a sandbox with preview
Freebuff Chat	Free AI chat	ChatGPT Plus, Perplexity	Deep-research style Q&A

Quick Start: Install to PR

1. Install the CLI

npm install -g freebuff

2. Enter your project and launch

cd your-project
freebuff

On first run it indexes your repo and keeps the index warm afterward. No sign-up, no API key, no credit card.

3. The full slash-command workflow

Freebuff ships polished slash commands that turn a vague idea into a mergeable PR:

/interview  →  clarify requirements
/plan       →  make an implementation plan
implement   →  write the code automatically
/review     →  code review

After each response, Freebuff proposes three clickable next steps so the conversation never dead-ends.

Nine Built-in Specialized Subagents

Freebuff ships 9 specialized subagents out of the box, orchestrated automatically by the main agent: code-reviewer, browser-use, file-picker, thinker-with-files-gemini, and more — covering coding, retrieval, and review end to end.

The "Free Forever" Business Model

Freebuff's free tier isn't a limited-time promo; costs are covered by text-only ads in the terminal, shown only between agent turns — never inside generated code, never as popups. The team promises the core product will never ask for your credit card. If you genuinely want no ads, there's a paid upgrade path (Codebuff Pro), but the 95% of developers who just want to ship code are fine on free.

Regions & Limited Mode

Full-model Freebuff is available in 25+ countries. Outside those regions — or when using a VPN — Freebuff drops to limited mode: DeepSeek V4 Flash only, with 6 one-hour sessions per day. Still free. The full-mode list expands every month.

Tips & Caveats

Code privacy: Connected repositories and uploaded files are not shared with ad providers, but prompts and messages may be analyzed to personalize ads. Models labeled "May use data for AI training" may use submissions for training.
Sensitive code: For private/sensitive code, read the official privacy FAQ before deciding.
Good fits: Rapid prototypes, personal projects, learning, and handing an existing repo to an agent for refactoring or test coverage.
The bigger idea: Freebuff replaces the classic "paid model API + paid coding tool" combo with a free agent — one of the most direct ways to cut AI costs.

Summary

Freebuff turned "calling frontier models" from a pay-per-use API bill into an ad-subsidized, zero-cost experience. It's not an API platform, yet it puts free access to top-tier models like DeepSeek V4, MiniMax M3, and GLM 5.2 right into your terminal and browser.
