什么是 Supabase?

Supabase 是一个基于 PostgreSQL 的开源后端即服务平台。它提供完整的数据库、身份验证、文件存储、实时订阅和边缘函数——所有功能都通过简洁的控制台和精心设计的客户端库实现。

核心卖点:Firebase 的所有功能,但构建在开源技术上,必要时可以自托管。

核心功能

PostgreSQL 数据库

与 Firebase 的 NoSQL 方式不同,Supabase 提供完整的 PostgreSQL。编写 SQL、使用连接、创建视图——你可以期望从正规数据库中获得的一切。行级安全让你在数据库层面控制访问。

身份认证

内置认证支持邮箱/密码、魔术链接和 20+ OAuth 提供商(Google、GitHub、Apple 等)。它基于 GoTrue,与数据库无缝集成。

实时功能

订阅数据库变更的实时推送。非常适合协作应用、仪表板和聊天。实时引擎基于 Phoenix Channels 构建。

存储

带有自动 CDN 交付、图片转换和细粒度访问策略的文件存储。

价格方案

免费套餐包括 500MB 数据库、1GB 文件存储和 50,000 月活用户。Pro 计划每月 $25,取消项目暂停并大幅提高所有限制。

适合人群

  • 全栈开发者——想要无需操心的后端
  • 团队——从 Firebase 迁移且需要 SQL
  • 初创公司——从第一天起就需要认证、数据库和存储
  • AI 应用开发者——使用向量嵌入

总结

Supabase 是想要 Firebase 的便利性和 PostgreSQL 强大功能的开发者的最佳后端选择。它开源、设计精良,免费套餐确实实用。
