Show HN: Open Source B2B SaaS Starter Kit (Go, Next.js, RBAC, Polar)
- moh_quz 10mo agoHi HN, I realized I was spending the first 3 weeks of every new B2B project just wiring up "boring" infrastructure like Authentication, Team Invites, and Billing webhooks. I decided to open-source my internal kit (MIT Licensed) to fix this. The Goal: Help founders skip the plumbing and start building their unique business logic on Day 1. The Stack: Backend: Go 1.23 (Modular Monolith with sqlc). Frontend: Next.js 15 (App Router). Included: Pre-configured RBAC, Multi-tenancy, Billing (Polar), and a pgvector RAG pipeline. It’s opinionated, but it saves you from "Decision Fatigue" when launching a new product. Happy to answer questions!
