I built B2B SaaS OS – Next.js 16 + Supabase starter with an automated 8-point security test runner

hello guys, Most SaaS boilerplates give you pre-built UI components and basic auth, but leave you completely on your own when it comes to hardening multi-tenant architecture and backend security testing. I built B2B SaaS OS (andrady.co) to solve this. It’s a Next.js 16 + Supabase starter focused on proven database security: 🛠️ Key Technical Features: Database-level isolation: Multi-tenancy enforced at the PostgreSQL RLS layer via JWT claims (not fragile JS middleware checks). Automated 8-poin

AI 分析

痛点:用 Next.js + Supabase 做多租户 B2B SaaS 的开发者,在 PostgreSQL RLS 隔离、权限提升和 webhook 竞态等后端安全环节几乎无参考,容易埋下跨租户数据泄漏漏洞。

目标用户:使用 Supabase/Next.js 独立开发或小团队构建多租户 B2B SaaS 的开发者,以及已有线上多租户项目、担心数据隔离安全的团队。

证据:Most SaaS boilerplates give you pre-built UI components and basic auth, but leave you completely on your own when it comes to hardening multi-tenant architecture and backend security testing. / Automated 8-point Security Runner: An integration test suite built into the repo that checks for cross-tenant leaks, SECURITY DEFINER privilege escalation, and Stripe webhook race conditions. / I built a free self-assessment tool where you can test your setup against these 8 failure modes in ~2 minutes

变现:boilerplate 买断制授权($199–499 一次性,含终身更新与私有 Discord);免费 RLS 安全自测工具作为获客入口,转化到付费模板;后续可衍生「多租户安全审计」按次收费服务($500–2000/次)。

MVP:2 周可完成:一个 Supabase 多租户种子仓库(JWT claims + RLS 策略 + org 切换 + RBAC + Stripe 订阅),外加 8 条可运行集成测试(跨租户读写泄漏、SECURITY DEFINER 提权、webhook 重放/竞态、service_role key 误用等),再配一个在线 2 分钟自测脚本从用户自己的 Supabase 项目拉取 schema 做静态检查,作为落地页 lead magnet。

竞品:ShipFast、Makerkit、supastarter、Ship SaaS、Supabase 官方 Next.js Starter、Vercel SaaS Starter Kit

摘要:这是 r/SideProject 上一位开发者发布的产品:Next.js 16 + Supabase 的 B2B SaaS 启动模板(andrady.co),核心卖点是在 PostgreSQL RLS 层强制多租户隔离,并内置「8 点安全测试运行器」检测跨租户泄漏、SECURITY DEFINER 提权与 Stripe webhook 竞态,另附免费自测工具。帖中未给出任何价格、收入或付费用户原话,需求强度靠 SaaS boilerplate 这一已被验证的品类支撑;机会点更偏向「多租户安全自测/审计」这一细分切口,而非又一个通用模板。
