开源协议的选择和合规检查是开发者在项目开发中常常忽视但至关重要的环节。选错协议可能导致法律纠纷，引用不兼容的开源组件可能带来合规风险。
License Analyzer 利用 AI 多智能体协作，帮助开发者：
- 根据项目需求智能推荐最合适的开源协议
- 检查项目依赖的开源组件是否存在协议冲突或法律风险
- 直观对比多个协议的权限、条件和限制
协议选择 — 描述你的项目，AI 推荐最适合的开源协议，支持对比和一键生成 LICENSE 文件
合规检查 — 上传依赖文件或输入 GitHub 地址，自动分析每个依赖的协议风险等级并给出修复建议
协议对比 — 从权限、条件、限制等 14 个维度对比多个协议的差异
多模型支持 — 内置免费模型开箱即用，同时支持 DeepSeek、通义千问、Claude、OpenAI 及任意 OpenAI 兼容接口

- 将代码推送到 GitHub
- 在 Render 创建 Web Service，连接仓库
- 配置：
- Build Command:
npm install && npm run build - Start Command:
npx next start -p $PORT - Instance Type: Free
- Build Command:
- 在 Environment 中添加上述环境变量
- 部署完成后访问
https://your-app.onrender.com
注意：Free 计划 15 分钟无流量会休眠，首次访问需等待冷启动。SQLite 数据在每次部署时自动重建。

Choosing the right open-source license and ensuring compliance with dependency licenses are critical yet often overlooked aspects of software development. A wrong license choice can lead to legal disputes, and using incompatible open-source components can introduce compliance risks.
License Analyzer leverages a multi-agent AI pipeline to help developers:
- Get intelligent license recommendations based on project requirements
- Check dependencies for license conflicts and legal risks
- Visually compare licenses across permissions, conditions, and limitations
License Selection — Describe your project, and AI recommends the best license with one-click LICENSE file generation
Compliance Check — Upload dependency files or enter a GitHub URL to analyze license risks for each dependency
License Comparison — Compare multiple licenses across 14 dimensions including permissions, conditions, and limitations
Multi-Model Support — Built-in free model works out of the box; also supports DeepSeek, Qwen, Claude, OpenAI, and any OpenAI-compatible endpoint
