Supabase(开源 + PostgreSQL)和 Firebase(Google + NoSQL)是 BaaS 领域的两大选择。本文帮你根据项目需求做出正确选型。

Supabase (open-source + PostgreSQL) and Firebase (Google + NoSQL) are the two leading BaaS choices. This guide helps you choose based on project needs.

什么是 BaaSBackend-as-a-Service 让前端开发者不需要自己搭建服务器、写 API、管理数据库。注册一个账号,就能拥有数据库、认证、文件存储、实时订阅等后端能力。核心对比维度SupabaseFirebase数据库PostgreSQL(关系型)Firestore(文档型 NoSQL)开源是(可自托管)否实时功能PostgreSQL 变更订阅原生实时同步认证内置(邮箱/社交/SAML)内置(邮箱/社交/电话)文件存储S3 兼容Cloud Storage边缘函数Deno Edge FunctionsCloud Functions定价免费层更慷慨按用量付费SQL 支持完整 SQL无(NoSQL 查询)供应商锁定低(PostgreSQL 通用)高(Firestore 专有)选型建议选 Supabase:需要关系型数据、复杂查询、SQL 经验丰富、担心供应商锁定选 Firebase:需要强实时同步、移动端优先、Google 生态集成、快速原型iDev 的实践对于客户的 MVP 项目,我们越来越多地使用 Supabase。原因:PostgreSQL 的灵活性远超 Firestore,项目成长后迁移到自建后端的成本很低。Firebase 我们主要用于需要实时聊天或推送通知的移动端项目。
